1.1. Knottingley Power Limited

1.1.1. Knottingley Power Limited (hereafter KPL) is the development company which proposes to build and operate a natural gas fired Combined Cycle Gas Turbine (CCGT) power plant in Knottingley, West Yorkshire. KPL’s ultimate parent company is ESB.

1.1.2. ESB is a state-owned electricity company based in Ireland with a portfolio of investment projects across the world. ESB currently has projects in over 35 countries, including the UK, Europe, Middle East, Asia and Africa.

1.1.3. ESB has been in the British energy market since the early 1990s as developer and owner of Corby Power Limited in Northamptonshire (350MW) and the 842MW CCGT plant at Marchwood near Southampton. ESB will also commence construction in late 2012 of the 860MW CCGT plant at Carrington, near Manchester.

1.1.4. ESB also builds and operates renewable generation projects. In the UK, ESB owns West Durham windfarm (24MW), Fullabrook Down windfarm (66MW) and Mynydd Y Betws windfarm (37.5MW) which is under construction.

1.1.5. For details of these and other ESB projects please visit: http://www.esb.ie.

1.2. Knottingley Power Project

1.2.1. The Knottingley Power Project will be capable of generating up to 1,500MW (approximately) of electricity, equivalent to the annual electricity consumption of about two million homes.

1.2.2. The major elements of the Knottingley Power Project are described below.

Combined Cycle Gas Turbine Power Plant, Cooling Water Infrastructure and Electrical Grid Connection

1.2.3. KPL intends to develop a CCGT Power Plant with capacity to generate up to 1,500 MW (approximately) of electricity on the site of a former chemical works east of Knottingley in West Yorkshire.

1.2.4. Cooling water infrastructure to convey water from the River Aire is the most likely option to cool the steam condensers which form part of the CCGT Power Plant although the Aire and Calder Canal will also be considered if suitable.

1.2.5. The electricity generated by the CCGT power plant will be exported to the National Grid Electricity National Transmission System. Connection to the National Transmission System will involve an overhead line connection from the new substation on the power plant site to the existing 400kV overhead line (OHL) approximately 250m to the east. Two existing towers on the 400kV overhead line will be replaced with two new towers to be located adjacent to the current locations.

Gas Pipeline

1.2.6. The CCGT power plant will be fuelled by a supply of natural gas.

1.2.7. The supply of natural gas will be taken from a new underground Gas Pipeline (together with associated infrastructure, principally an Above Ground Installation AGI)) which will be constructed between the CCGT power plant site and the National Grid Gas National Transmission System.

1.2.8. The new underground Gas Pipeline will be approximately 8 kilometres (km) in length.



1.3. Need for the Development

1.3.1. The development of the Knottingley Power Project is required in order to contribute towards ensuring reliability of electricity supply in the UK. Generating electricity from renewable energy sources can help the UK to meet their carbon-reduction commitments. However renewable sources alone cannot be relied upon to meet demand at all times as they are intermittent energy sources.

1.3.2. To ensure that there is reliability of supply, the electricity generation mix needs to have a balance of electricity generating technologies which produce stable and controllable amounts of electricity continuously.

1.3.3. Within this scenario, gas-fuelled electricity generating technologies can play a significant role in maintaining the UK’s reliability of supply, whilst also producing stable and controllable amounts of electricity.

1.3.4. In the second Annual Energy Statement (AES) (November, 2011), the Department of Energy and Climate Change (DECC) directed the need to build a new energy portfolio through securing investment in the UK energy sector and building power plants that will “fuel our future prosperity, and the infrastructure that will deliver it”.

1.3.5. In line with this the AES acknowledged the need for gas to continue to feature strongly in the energy mix, and also stated that while it is important that businesses play their part in the transition to a low-carbon economy, it is important to also remain competitive.

1.4. Consenting Regime

1.4.1. As the Knottingley Power Project will have an approximate generating capacity up to 1,500MW (approximately) it will require a Development Consent Order (DCO) under Section 31 of the Planning Act 2008, as it represents a Nationally Significant Infrastructure Project (NSIP) that is above the 50MW threshold for power stations. The Knottingley Power Project will also include an above ground connection to an existing 400kV National Grid power line and this is also a Nationally Significant Infrastructure Project (NSIP) as it is above the 132kV threshold for above ground electric lines.

1.4.2. An application will be submitted to the Planning Inspectorate’s (PINS) National Infrastructure Directorate. PINS role will be to consider and make recommendations to the Secretary of State who will determine the application. To support the application an Environmental Impact Assessment (EIA) will be prepared. Other documents will also be prepared to support the DCO application. These will include:

Statement of Community Consultation (SoCC);

Consultation Strategy;

Consultation Report;

Explanatory Memorandum – this will address the agreed provisions or conditions that will apply to the Knottingley Power Project;

Book of Reference – this outlines those with a land interest and affected persons;

Environmental Statement (ES);

Statement of Common Ground

Flood Risk Assessment (FRA);

Statement of Matters covered by the Environmental Protection Act 1990 Section 79(1);

Sustainability Statement; and



Various plans of the Site and the proposed development: to include the application area, land boundary, proposed layout.

1.5. Preliminary Environmental Information

1.5.1. Pursuant to Sections 2 and 10(b) of the EIA Regulations, Preliminary Environmental Information (PEI) must be made available for consultation under Section 47 of the Planning Act 2008. The PEI is presented in this PEI Report (PEIR) which has been revised and updated as new information became available over the period leading up to the submission of the DCO application.

1.5.2. The PEIR indicates the key items of environmental information and issues that have been addressed. In summary, the PEIR outlines the following by each environmental topic:

Baseline description summary;

Proposed approach and surveys to be undertaken;

Initial outcomes; and,

Further environmental information provided to Section 47 Consultees during the Pre-Application stage.



2.1. Overview

2.1.1. It is proposed to develop a CCGT Power Plant on a site located to the east of Knottingley, West Yorkshire on a 20 hectare site that includes the former Oxiris Chemical Works and adjoining agricultural land.

2.1.2. The Knottingley Power Project comprises a number of components which include the power plant, cooling water infrastructure, electrical grid connection and the gas pipeline. These are grouped under two main headings as follows:

Power Plant: A CCGT with a capacity to generate up to 1,500 MW (approximately) of electricity on the site of a former chemical works and agricultural land east of Knottingley in West Yorkshire. Cooling water infrastructure will form part of this application. The electricity generated by the CCGT power plant will be exported to the National Grid Electricity National Transmission System by means of a short connection to an existing 400kV overhead line approximately 250m to the east of the site. The connection to the National Grid Electricity National Transmission System will also be part of this application. These elements of the Knottingley Power Project (CCGT power plant, cooling water infrastructure and connection to electricity grid) are referred to as the CCGT Power Plant. The location of the Power Plant Site is shown in the figure CCGT Power Project Location Plan which is presented in the Figures section.

Gas Pipeline and Associated Infrastructure: The CCGT power plant will be fuelled by a supply of natural gas. The natural gas will be taken from a new underground Gas Pipeline which will be constructed between the CCGT Power Plant site and the National Grid Gas National Transmission System. The new underground Gas Pipeline will be approximately 8 km in length, and will run from the CCGT power plant site to a new Above Ground Installation which will be constructed near Gateforth (adjacent to the National Grid Gas National Transmission System pipeline). The proposed route of the underground Gas Pipeline, and the associated corridor which was presented previously in the Environmental Scoping Report, is shown in the figure Gas Pipeline Route and Assessment Corridor which is presented in the Figures section.

2.2. Site Location and Surroundings

Power Plant Site Selection

2.2.1. The proposed site offers a number of advantages that make it suitable for power generation.

2.2.2. These include,

The close proximity of the existing 400kV overhead line situated within 250 m to the east of the power plant site;

The proximity to the Gas National Transmission System within 8 km of the site;

The industrial setting of the site.

Availability of sufficient land designated for energy generation use in the local planning policy;

Transport infrastructure that will accommodate construction traffic by road; other options such as canal and rail will be investigated;



Proximity to a cooling water supply from the river Aire or the Aire and Calder Canal; and

Redevelopment of a brownfield former chemical works is expected to be feasible at reasonable cost.

2.2.3. It is therefore considered that the proposed site is very suitable for the intended use of power generation.

2.2.4. As part of its strategic development planning, ESB has undertaken extensive research into sites suitable for development of CCGT projects. Through consultation with National Grid, the Knottingley location was identified as an area of the electricity network where demand for new generation and minimal new overhead line infrastructure would allow connection of new generation in a reasonable timescale.

2.2.5. Greenfield sites close to the existing National Grid infrastructure were considered. However, national planning policy and local planning policy aim to protect the countryside for its intrinsic value and encourage development of brownfield sites such as the former chemical works site at Knottingley, where possible.

2.2.6. The project location is shown in the figure below.

Project Location



Description of the Power Plant Site

2.2.7. The Power Plant Site will include the power generation equipment and substation and will be located on the former chemical works and agricultural area to the east of the development site. The area is outlined clearly in the figures CCGT Power Plant Indicative Site Layouts presented in the Figures section.

Site History and Existing Use

2.2.8. Historically the site had comprised agricultural fields, which were divided by Common Lane which continues to exist as a track through the site. Based on information provided by former chemical works employees and from maps published by the Ordnance Survey (OS) it is understood that development of a chemical works on western part of the site was commenced by Yorkshire Tar Distillers in 1949 on land that had previously been in agricultural usage.

2.2.9. The chemical plant operated continuously until it was demolished in 2009. The north-western part of the site now consists of vacant derelict land including areas of hardstanding. There are also occasional small derelict buildings near the former chemical works entrance. The eastern and southern parts of the site continue to comprise agricultural fields.

2.2.10. Further information on the Site, as well as the wider Indicative Red Line Boundary area will be included in the baseline description provided for each of the specialist environmental assessments. A detailed site description, including information relating to site history, will be presented in the ES.

Power Plant Site Surroundings

2.2.11. The proposed power plant site is bound by the Aire and Calder Navigation Canal to the north and Kellingley Colliery to the north east. A railway line runs along the southern boundary of the power plant site. Agricultural land bound the power plant site to the south and west. The power plant site is within the administrative boundary of Wakefield Metropolitan District Council (Wakefield MDC), Wakefield Metropolitan MDC and the boundary of Selby District Council (Selby DC) lies 70m to the north east. In addition the site lies within North Yorkshire County Council (North Yorkshire CC).

2.2.12. The proposed power plant site lies approximately 3 km to the east of Knottingley town centre, 7 km north east of Pontefract town centre, approximately 9.5 km south east of Castleford, 13 km south west of Selby town centre and 24 km south east of Leeds town centre.

2.2.13. The closest residential dwellings are located within 100m of the north of the Site.

2.2.14. Brockadale as well as Fairburn and Newton Ings are the nearest Sites of Special Scientific Interest (SSSI) to the Knottingley Power site at approximately 5.3 km to the south and 6 km to the north west respectively.

Gas Pipeline Route Selection

2.2.15. When considering the main alternatives for the route of the Gas Pipeline, an initial area of consideration was used, roughly bounded by the M62, A1 / A162, A63 and A19.

2.2.16. The initial area of consideration is shown below.



AERIAL PHOTOGRAPH SHOWING THE INITIAL AREA OF CONSIDERATION

Alternative Options for Gas Supply

2.2.17. From a technical / engineering perspective, identification of potential routes for the Gas Pipeline began with establishing the optimal point at which to take gas from the existing UK National Grid Gas System.

2.2.18. The UK National Grid Gas System is split into two parts:

The National Transmission System, also known the United Kingdom Transmission System (UK-T); and,

The Local Distribution System, also known as the United Kingdom Distribution System (UK-D).



National Transmission System

2.2.19. The National Transmission System represents the infrastructure designed to transmit gas around the country, and is the backbone of the UK gas infrastructure reaching all points of mainland Britain.

2.2.20. National Transmission System infrastructure is generally larger pipelines (greater than 24 inches / 600 mm in diameter) operating at high pressure (approximately 70 bar g).

2.2.21. Two 1200 mm high pressure steel pipelines are the nearest National Transmission System pipelines to the proposed CCGT power plant site. These are:

Feeder 29 (Pannal to Asselby); and,

Feeder 7 (Pannal to Asselby Duplicate).

2.2.22. Feeder 29 was commissioned for use on the National Transmission System in 2008, and was introduced to reinforce a section of Feeder 7. Feeder 29 pipeline passes less than 7 km from the CCGT power plant site at its nearest point.

2.2.23. Feeder 7 is located north of Feeder 29, and presents another option to connect to the National Transmission System. However, Feeder 7 is 15 km away from the CCGT power plant site and therefore, would only be considered if capacity in Feeder 29 was unavailable.

2.2.24. The location of Feeder 29 (and the location of Feeder 7) is shown below. The National Transmission System pipelines are shown in pink and the location of the CCGT power plant site is indicated by the red marker.

2.2.25. The nearest possible National Transmission System connection to the south has not been considered as this is over 50 km away near to Newark-on-Trent.

NATIONAL TRANSMISSION SYSTEM SHOWING THE ROUTEING OF FEEDER 7 AND FEEDER 29

2.2.26. The National Transmission System connects into the Local Distribution System, which distributes the gas supply to where it is required.



Local Distribution System

2.2.27. The Local Distribution System is comprised of generally smaller pipelines (less than 24 inches / 600 mm in diameter) operating at lower pressure (approximately less than 50 bar g).

2.2.28. To connect the CCGT power plant to the Local Distribution System, the presence of a suitably high pressure and large diameter pipeline in the local area is required. There are two high pressure / large diameter pipelines (belonging to the Local Distribution System) in the area of consideration. These are:

The ‘Knottingley to Chapel Haddlesey’ line; and,

The ‘Barwick to Knottingley’ line.

2.2.29. The ‘Knottingley to Chapel Haddlesey’ line supplies gas to the Knottingley Above Ground Installation (AGI), and the ‘Barwick to Knottingley’ line transports gas away from Knottingley AGI.

2.2.30. The Knottingley AGI is situated approximately 700 m to the north west of the proposed CCGT power plant site and can be seen below.

LEGEND

Medium Pressure Pipeline

Low Pressure Pipeline

2.2.31. This shows that (apart from the high pressure / large diameter pipelines) at the Knottingley AGI gas is supplied to:

A 200 mm high pressure pipeline that feeds into a 300 mm low pressure pipeline; and

A 450 mm medium pressure pipeline.



Evaluation of Options for Gas Supply

2.2.32. The above options for gas supply were evaluated based on a qualitative analysis of their strengths and weaknesses. The evaluation considered a number of factors, including: technical; planning; land ownership; environmental; and, cost.

2.2.33. The evaluation indicated that the options for gas supply from the National Transmission System were preferred.

Alternative Gas Pipeline Routes

2.2.34. Based on an option for gas supply from the National Transmission System, five alternative routes were identified. The five alternative routes were:

Route 1:Route 1 takes a northerly exit from the CCGT power plant site, heading immediately under the Aire and Calder Navigation Canal and the A645 (Weeland Road). Route 1 then turns north-east and continues on to Kellington. At Kellington, Route 1 turns towards the north, but is still heading in a roughly north-east direction. Route 1 then crosses the River Aire, and continues north-east towards the National Transmission System. The connection to the National Transmission System would be made south of Gateforth, off Pale Lane.

Route 1A:Route 1A takes a northerly exit from the CCGT power plant site, heading immediately under the Aire and Calder Navigation Canal and the A645 (Weeland Road). Route 1A turns north-east and follows Route 1A for approximately 400 m before turning north, thus diverging away from Route 1. Route 1A crosses the River Aire, and continues north towards the National Transmission System. The connection to the National Transmission System would be made near to Gateforth Hall, south of Hambleton.

Route 2:Route 2 takes an easterly exit from the CCGT power plant site, and continues east to cross Beal Lane. Route 2 then turns north to cross the Aire and Calder Navigation Canal. Route 2 continues north, before joining and following Route 1. The connection to the National Transmission System would be made south of Gateforth, off Pale Lane.

Route 2A:Route 2A is similar to Route 2, but proposes a different option for crossing the Aire and Calder Navigation Canal.

Route 2B:Route 2B is similar to Route 2, but proposes a different route for crossing the River Aire.

Alternative Connection Points (to the National Grid National Gas Transmission System)

2.2.35. As described above, Feeder 29 is considered to present the best option for connection to the National Transmission System. Based on this consideration, and in order to minimise the number of probable crossings, only a short section of Feeder 29 was considered. This short section falls between the A63 and the A19. A connection to Feeder 29 at this point would represent the shortest distance between the CCGT power plant site and Feeder 29, and would also limit the number of major crossings that must be considered.

2.2.36. Based on this, there are two potential options for connection to the National Transmission System. These are:

NTS Connection Option 1: Connection to the National Transmission System near to the Gateforth Hall, south of Hambleton.



NTS Connection Option 2: Connection to the National Transmission System south of Gateforth, off Pale Lane.

2.2.37. These options for connection to the National Transmission System are shown below.

Point

Alternative Termination Points (i.e. Entrance Point on the CCGT Power Plant Site)

2.2.38. Given there are no suitable options for a connection (to the National Grid National Transmission System) to the south, a southerly location for the entrance point for the Gas Pipeline on the CCGT power plant site is not considered. Likewise, as land to the west may be reserved for possible residential / light industrial applications, a westerly location for the entrance point for the Gas Pipeline on the CCGT power plant site is not considered.

2.2.39. Therefore, northerly and easterly locations for the entrance point for the Gas Pipeline on the CCGT power plant site were considered. These locations are shown below.



LOCATIONS OF THE POTENTIAL PIPELINE ENTRY POINTS AT THE CCGT POWER PLANT SITE

Evaluation of Alternative Gas Pipeline Routes (including Connection Points and Termination Points)

2.2.40. Based on the above alternative Gas Pipeline routes, alternative connection points (to the National Grid National Gas Transmission System) and alternative termination points(i.e. entrance point on the CCGT power plant site), a further evaluation of options for gas supply was undertaken.

2.2.41. The evaluation was undertaken based on a high-level qualitative analysis of their strengths and weaknesses. Again, the evaluation considered a number of factors, including: technical; planning; land ownership; environmental; and, cost.

2.2.42. During the evaluation, it was found that Routes 1A and 2B would cross an area currently being considered under a separate application for Planning Permission. Therefore, Routes 1A and 2B were discounted.

2.2.43. Accordingly, Routes 1, 2 and 2A were taken forward into the Environmental Scoping Report and Public Consultations for further consideration.

2.2.44. A second further evaluation was undertaken following the receipt of the Environmental Scoping Opinion, the completion of Stage 1 of the Public Consultations and further investigation (including more detailed consideration of technical / planning / land ownership / environmental / cost issues). Again, the evaluation was undertaken based on a qualitative analysis of their strengths and weaknesses. During the second further evaluation, Routes 2 and 2A were discounted.

2.2.45. Accordingly, Route 1 (and its associated connection point and termination point) was selected as it represents the preferred option.

Gas Pipeline Route Evolution and Refinement

2.2.46. Over the course of the EIA process, the route of the Gas Pipeline has evolved and a number of minor route refinements have been made.



2.2.47. A summary of the initial minor route refinements are:

At the CCGT power plant site, minor route refinements have been undertaken such that the Gas Pipeline and the preferred entrance point for the Gas Pipeline on the CCGT power plant site are aligned;

To the north of the A645 (Weeland Road), minor route refinements have been undertaken due to the Gas Pipeline crossing land with Development Potential;

At Beal Carrs, minor route refinements have been undertaken such that the route of the Gas Pipeline is further to the east, thus avoiding the centre of the Beal Carrs area;

To the north of Birkin Road, minor route refinements have been undertaken based on the proposed turbine locations of the Prowind Wind Farm ; and,

South of Tom’s Wood, the minor refinements have been made to the location of the AGI based on Land Owner discussions.

2.2.48. In addition to these initial route refinements, it should be noted that further (minor) route refinements may occur at the detailed design stage. There further (minor) route refinements would be a result of: further Stakeholder Consultation; further Land Owner / Land Occupier negotiations; accuracy of existing pipeline / services / utilities information; and, additional ground investigations. As such, any further (minor) route refinements would be limited and take place within the application / survey area covered by the EIA.

Gas Pipeline Route Surroundings

2.2.49. The proposed route of the Gas Pipeline would pass through the administrative boundaries of Wakefield MDC and Selby DC.

2.2.50. Further description of the proposed route surroundings is provided in Section 2.4.

2.3. Description of Proposed CCGT Power Plant

Overview

2.3.1. The Knottingley Power Plant will generate up to 1,500 MW of electricity from the use of natural gas. The CCGT Power Plant elements include the power generation process and the water cooling infrastructure as described below.

Fuel Type and Source

2.3.2. Natural gas will be taken from an offtake on the National Grid Gas National Transmission System. This will then be transported to the CCGT power plant via a gas pipeline.

Power Generation Process

2.3.3. There are two alternative power plant configurations for the development possible, as follows,

- Three 500MW (approx.) power units (1500MW total approximately)

- Two 600MW (approx.) power units (1200MW total approximately)

The alternative layouts are shown in the figures CCGT Power Plant Indicative Site Layoutspresented in the Figures section.

2.3.4. The power plant will be located on the former chemical works area and on agricultural land to the east of the proposed site. The power plant will consist of two 600MW (approx.) units or three 500MW (approx.) units. Each unit will include combustion and power generation equipment.



2.3.5. In each gas turbine combustor, gas will be mixed with compressed air and burned. The hot combustion gases will expand, rotating the turbine blades at high speed. This in turn will drive generators to produce electricity for the national grid.

2.3.6. The hot exhaust gases from the gas turbine contain significant amounts of recoverable energy. The gases will be passed through the heat recovery boiler to produce steam. The high pressure steam will then be used to drive a steam turbine which will generate further electricity. The waste gases will be expelled to the atmosphere via a stack.

2.3.7. Each power unit may have an individual stack. Pollutants (oxides of nitrogen and carbon monoxide) are emitted at relatively low concentrations.

2.3.8. The term ‘combined cycle’ refers to the use of two processes (thermodynamic cycles) to produce electricity. The burning of natural gas in a gas turbine is the first. The recovery of heat from the waste gases to produce steam to drive a steam turbine is the second. Together, these processes capture much more of the energy in the gas. Modern CCGT plants of this kind represent advanced generating technology as they offer high operating efficiencies and low emissions.

2.3.9. A schematic of the power generation process associated with the Knottingley Power Project is provided below in Diagram 1.

Diagram 1: Schematic of the Power Generation Process



2.3.10. Buildings will be constructed to house the gas turbines, steam turbines and associated plant. Further details on the layout of the buildings are presented in the CCGT Power Plant Indicative Layouts in the Figures section. Typical dimensions for the principal buildings and structures are provided in the table below.

The Cooling System and Aqueous Discharges

2.3.11. There is a requirement for a cooling system to condense the steam used in the power generation process once it has been exhausted through the steam turbine, and before it is returned to the boiler. In general, three cooling options are available namely, once through (direct) water cooling, recirculation (closed loop) water cooling and air cooling using air cooled condensers.

2.3.12. Once through water cooling consists of a high efficiency water-cooled condenser and a once-through cooling water system whereby a relatively large volume of river water or seawater is pumped continuously through the condenser and the entire flow is returned to the river or sea. It is usually the most energy efficient of the cooling technologies available for power plants. This method would require the abstraction of significant quantities of water from an accessible water source and the discharge of water of up to 9 oC warmer than ambient water temperature into an accessible water source. In the UK, this cooling system is feasible only at coastal locations where large volumes of water are available.

2.3.13. For this project, two methods are feasible, these being recirculation cooling and air-cooled condensers. These options are outlined below.



2.3.14. A recirculation cooling system consists of a closed loop whereby cooling water is circulated through the condenser and cooled in a hybrid cooling tower. Cooling water is lost to the system by evaporation and a proportion is discharged to control the build up of suspended solids. These losses are replaced by abstraction from a water body such as a nearby river. The abstraction requirements for a recirculation cooling system are less than 5% that required for once through cooling. The discharge temperature would typically be no greater than 9 oC warmer than ambient water temperature. The hybrid nature of the cooling structure results in a water vapour plume being visible for a limited number of hours per year under certain climatic conditions.

2.3.15. A recirculation cooling system requires the construction of an intake and outfall structure. There are several options for the abstraction and discharge of cooling water, which include:

a) Abstraction from and discharge to the River Aire. This would involve dual pipelines of approximately 1 km in length. This is the preferred option.

b) Abstraction from and discharge to the Aire and Calder Navigation Canal requiring a very short pipeline;

c) Abstraction from the Aire and Calder Navigation Canal and discharge to the River Aire which would involve a single pipeline of approximately 1 km in length;

d) Abstraction from the River Aire and discharge to the Aire and Calder Navigation Canal which would involve a single pipeline of approximately 1 km in length

2.3.16. For the preferred option a), the route of the cooling water pipelines (abstraction and return) would run parallel to the gas pipeline in the same corridor over much of their length before routing north over the final 200m approximately to the River Aire. The cooling water pipelines will be included as associated development in the DCO application for the Knottingley Power Project.

2.3.17. The proposed route for the cooling water pipelines is shown in the figure Water Pipelines Route. The route starts at the CCGT power plant site, and exits the site to the north and under the Aire and Calder Navigation Canal. This crossing will be made using a trenchless technique, such as a Horizontal Directional Drill (HDD).

2.3.18. The route then continues north to cross the A645 (Weeland Road). This is the only major road crossing. The A645 (Weeland Road) is a busy road and therefore, it has been assumed at this point that the best approach for this crossing would be an Auger Bore.

2.3.19. The route continues north, then heads sharply north-east passing under a 400kV overhead power line, including: a major transmission line of 400kV. The route then heads north to the pump house a short distance from the river Aire.

2.3.20. As far as possible, water pipelines will be constructed by conventional methods such as trenching and using trenchless techniques at canal/road crossings. The selection of the most appropriate method will be based on environmental and economic factors. The location of the return outfall will also be based on thermal plume dispersion modelling which will also be agreed with consultees, including the Environment Agency.

2.3.21. Air cooled condensers work on a similar basis to the radiator in motor car. Fans draw ambient air through an array of tubes carrying exhaust steam from the steam turbine where it cools and condenses and is returned to the boiler. This method results in reduced plant efficiency, thereby increasing fuel consumption and the emission of exhausts gases for each unit of electricity produced.

2.3.22. Air cooled condensers require no water intake or discharge and result in no visible plume. The advantage of this method is it avoids any potential issues associated with water cooled systems (water abstraction, treatment, discharge and potential contamination of the steam water circuit). However, the disadvantage with air cooled condensers is that they are less thermally efficient particularly during the summer months.



2.3.23. KPL considers that a recirculation cooling system comprises BAT (Best Available Technique) at this location due to its efficiency balanced against water availability and environmental effects. The justification of recirculation cooling as BAT will be provided in the application for an Environmental Permit which will be submitted to the Environment Agency.

2.3.24. The quality and temperature of the water discharged back will be carefully controlled.

2.3.25. An application to abstract water from the river Aire (water abstraction licence application) was submitted to the Environment Agency in December 2012.

Electricity Export

2.3.26. A new Gas Insulated Switchgear (GIS) substation will be constructed at the north eastern corner of the site. This will enable the electricity generated by the power station to be transmitted to the National Grid.

2.3.27. A new electricity connection will be required to allow electricity generated by the power station to be exported to National Grid’s electricity transmission network. The electricity generated by the CCGT Power plant will be exported to the national grid by means of a short connection approximately 250m long to an existing 400kV overhead line near the site. The connection will require the replacement of two existing NG towers (pylons) which will be located adjacent to the towers they replace, on land to the east of power plant site adjacent to the substation. The connection to the NG will be included in the DCO application for the Knottingley Power Project.

Carbon Capture

2.3.28. It is proposed to design the Knottingley Power Project to be Carbon-Capture Ready (CCR) since it exceeds the 300MWe threshold for the consideration of Carbon Capture Readiness as outlined in NPS EN-2. A Carbon Capture Readiness Report is being undertaken and will be submitted with the final Environmental Statement (ES)

2.3.29. The CCGT Power Plant Indicative Layout in Figures shows that approximately 7 ha of land to the west of the proposed location for the power plant on the site has been made available for the future installation of a Carbon Capture Plant (CCP), if required.

2.3.30. An economic feasibility study will be presented with the DCO application to estimate the indicative cost of retrofitting CCS to the Knottingley plant. This will estimate approximate CO2 permit prices, guaranteed over the lifetime of the plant, which would result in the cost of generating electricity from such a plant being less than a standard CCGT (without CCS). It is considered that the analysis will demonstrate the conditions when it is economically feasible for CCS to be retrofitted to the proposed CCGT.

2.3.31. The ultimate decisions on the CCS solution will be taken at the appropriate time, considering such matters as the contemporaneous legislation, proven technology, best practices and economic feasibility as are relevant.

Combined Heat and Power

2.3.32. In preparing the DCO application, due regard will be give to the Department of Energy and Climate Change (DECC) guidance on section 36 of the Electricity Act 1989 applications1. In essence, the DCO application will demonstrate that KPL has explored the opportunities to develop Combined Heat and Power (CHP), including community heating schemes.

1 Information to Accompany Notifications Under Section 14(1) of the Energy Act 1976 and Applications Under Section 36 of The Electricity Act 1989, Department of Trade and Industry, March 2001



2.3.33. A CHP investigation will be undertaken as part of the DCO application which will involve identifying and contacting potential CHP users in the local area. This will initially be based on examining a map around the power plant based on a predetermined economic radius for heat transportation. Should any potential uses be identified, a ‘heat map’ of the local area would be produced incorporating community, commercial and industrial heat uses and opportunities. Within this ‘heat map’ area the identified users would then be classified into user sectors. Community opportunities would mainly consider residential and housing opportunities. Commercial opportunities would include any hotels, leisure centres, large corporate buildings, hospitals, universities, prisons, defence installations and accommodation complexes. Industrial opportunities would be readily identified by the industrial sector of those industries inside the ‘heat map’ radius.

2.4. Gas Pipeline

Overview

2.4.1. The CCGT power plant will be fuelled by a supply of natural gas.

2.4.2. The supply of natural gas will be taken from a new underground Gas Pipeline (together with associated infrastructure, principally an AGI) which will be constructed between the CCGT power plant site and the National Grid Gas National Transmission System.

2.4.3. The new underground Gas Pipeline will be approximately 8 km in length.

2.4.4. The Gas Pipeline will be included as associated development in the DCO application for the KPP.

Detailed Gas Pipeline Route Description

2.4.5. The proposed route for the Gas Pipeline is shown in the Figure: Gas Pipeline Route and Assessment Corridor.

2.4.6. The following provides a detailed description of the proposed route of the Gas Pipeline from a south to north direction, from the CCGT power plant site to the connection point to the National Transmission System.

2.4.7. The crossings are defined as follows:

RX – Road Crossing;

RLX – Railway Crossing;

WX – Water Crossing; and

MX – Miscellaneous Crossing2.

2.4.8. A number of public footpaths are also crossed. These are referenced in the text where relevant.

2.4.9. The route begins at the CCGT power plant site and heads immediately north and under the Aire and Calder Navigation Canal (WX1). This crossing will be made using a trenchless technique, such as a Horizontal Directional Drill (HDD).

2.4.10. The route then continues north to cross the A645 (Weeland Road) (RX2). This is the only major road crossing. Though the A645 (Weeland Road) is single carriageway, it is heavily used and therefore an open cut approach for this crossing would be disruptive. Therefore, it has been assumed at this point that the best approach for this crossing would be an Auger Bore.

2 Miscellaneous Crossings covers existing buried and overhead pipelines / services / utilities.



2.4.11. The route continues north, then heads sharply north-east passing under four overhead power lines, including: a major transmission line of 400 kV (MX3); a local transmission line of 66 kV (MX4); and, two local transmission lines of 33 kV (MX5) (MX6).

2.4.12. The route then approaches the west side of Kellingley Farm and passes between the main area of the Farm and the Fishery Area. The route crosses a farmer’s track, which contains a waste water pipeline (RX7), and it has been assumed at this point that the best approach for this crossing would be an Auger Bore.

2.4.13. The route then heads north-east crossing a ditch (WX8), which would be best approached using an Open Cut method.

2.4.14. The route continues north-east to cross Common Lane (RX9) and New Lane (RX10). It has been assumed at this point that the best approach for these crossings would be an Auger Bore.

2.4.15. The route then crosses two local transmission lines of 33 kV (MX11) and 66 kV (MX12), and leads into the crossing of Beal Lane (RX13). Whilst this is a country road, the volume of traffic normally experienced would mean that an open cut approach for this crossing would be disruptive. Therefore, it has been assumed that the best approach for this crossing would be an Auger Bore.

2.4.16. The next crossing is of a farmers track (RX14) in Beal Carrs, west of Kellington. This is likely to be an Open Cut crossing as it does not appear to connect any public access.

2.4.17. The route then takes a slight turn north, but is still heading in a roughly north-east direction to cross Marsh Drain (WX15). This drain includes a flood barrier. It has been assumed at this point that the best approach for this crossing would be an Auger Bore. This would ensure no interaction with the flood barrier.

2.4.18. The route continues north-east to cross a track (RX16). It has been assumed that the best approach for this crossing would be an Open Cut method.

2.4.19. The route then approaches and crosses the River Aire (WX17). This is a major water crossing, and this crossing will be made using a trenchless technique such as HDD.

2.4.20. The route then continues in a more northerly direction and crosses farmers track (RX18) and a field drain known as The Fleet (WX19). It has been assumed that the best approach for RX18 would be an Open Cut method, and the best approach for WX19 would be an Auger Bore.

2.4.21. The route continues north towards Birkin Road passing under two overhead transmission lines. The first being a major transmission line of 400 kV (MX20) and the second being a local transmission line of 66 kV (MX21).

2.4.22. The route then crosses Birkin Road (RX22). It has been assumed that the best approach for this crossing would be an Auger Bore.

2.4.23. The route then continues north and crosses the Local Distribution System 600 mm high pressure steel pipeline (the ‘Knottingley to Chapel Haddlesey’ line) (MX23). It has been assumed that the best approach would be to Auger Bore this crossing to avoid any interference.

2.4.24. The route then crosses Royd’s Road (RX24), which is a farmer’s track. It has been assumed that the best approach for this crossing would be an Open Cut method.

2.4.25. At this point, the route skirts the extents of the area under an application for Planning Permission for the Prowind Woodlane Windfarm.

2.4.26. The route then crosses two ditches (WX25 and WX26). It has been assumed at this point that the best approach for these crossings would be an Open Cut method.



2.4.27. The connection to the National Transmission System (via the AGI) is made just after the crossing of Pale Lane (RX27). It has been assumed that the best approach for this crossing would be an Auger Bore.

The Above Ground Installation

2.4.28. The AGI will be an un-manned facility. The AGI will comprise two separate compounds: one compound owned and operated by National Grid; and, one compound owned and operated by KPL. Accordingly, the overall AGI facility will likely comprise the following:

National Grid Compound Infrastructure (including: connection to National Transmission System Number 29 Feeder pipeline; isolation joint to electrically isolate the KPL pipework from the National Grid pipework; standby generator socket; Gas Vents; Emergency Shutdown Device (ESD); Instrument Kiosk; and, above ground pipework);

KPL Compound Infrastructure (including: PIG launcher (which allows an intelligent pig to run through the gas pipeline to conduct online inspection); standby generator socket; Gas Vents; Emergency Shutdown Device (ESD); Instrument Kiosk; and, above ground pipework); and,

Common AGI Infrastructure (including: fencing for security purposes; Security Lighting and CCTV; and Landscaping and Biodiversity (to be undertaken in consultation with the Local Planning Authority) to ensure the AGI blends in).

2.4.29. Each compound will be enclosed by a steel security fence approximately 2.7 m high. Furthermore, both compounds will be located within the overall AGI site enclosed by a stock-proof fence. There will be two double-gated entrances (one for the National Grid Compound and one for the KPL Compound). There will be emergency personnel exit gates for both compounds. Approximately 4.5 m high lighting columns will be erected to provide illumination should maintenance works be necessary in hours of darkness. These will also provide support for the CCTV cameras. Therefore, the equipment within the AGI (with the exception of lighting columns) will be no higher than 3 m.

2.4.30. A small car parking area may be installed outside the gated entrance.

2.4.31. Landscaping will be planted in order to screen the AGI. This will be agreed with Local Planning Authority.

Safety

2.4.32. Safety is of fundamental importance during every stage of planning, routing, design, construction and subsequent operation of a high pressure gas pipeline. As such, a number of appropriate safety considerations have been considered to ensure compliance with the requirements of the Health and Safety Executive (HSE) and ensure safe operation of the Gas Pipeline.

Design / Construction / Operation / Decommissioning

Design

2.4.33. The Gas Pipeline will be designed, constructed and tested to comply with the Institute of Gas Engineers’ (IGE) Recommendations on Transmission and Distribution Practice – IGE/TD/1: Edition 5, 2009 – Steel Pipelines and Associated Installations for High Pressure Gas Transmission (Pipeline Design Standard IGE/TD/1).

2.4.34. The Gas Pipeline will be constructed from high-grade welded steel pipe and will likely be sized up to 600 mm diameter (nominal). The Gas Pipeline will have a Maximum Incidental Pressure of 93.5 barg and a Maximum Operating Pressure of 85 barg.



2.4.35. The standard gas pipeline wall thickness will comply with the requirements of IGE/TD/1, which defines the minimum safe separation distance between a high pressure gas pipeline and normally inhabited buildings / major roads / major railways. This minimum safe separation distance is known as the Building Proximity Distance (BPD). If normally inhabited buildings / major roads / major railways are closer than 1 BPD (i.e. the gas pipeline is in an area where additional protection is required), thicker wall steel pipe (known as proximity pipe) will be used. The exact locations and lengths of where thicker wall steel pipe will be used will be confirmed throughout the assessment and detailed design stages.

2.4.36. The Gas Pipeline will be buried to a depth of cover which is in accordance with the Pipeline Design Standard IGE/TD/1 and Recognised Industry Standards. For example, depths of cover will be:

No less than 1.2 m in agricultural land;

No less than 2 m under road crossings; and

No less than 1.7 m under water crossings.

Construction

2.4.37. The majority of environmental impacts arising from the development of gas pipelines (and their associated infrastructure) occur during construction. The following describes the standard methods which are likely to be required in full or in part during the construction of the proposed Gas Pipeline. These construction methods represent proven methods that have been developed over many years from experience on similar projects.

2.4.38. Construction of an underground gas pipeline is typically by a pipeline "spread". This is defined as the unit of manpower, plant and equipment necessary to construct an underground gas pipeline, from surveying the route through to reinstatement of the land.

2.4.39. All construction activities are undertaken within a temporarily fenced-off strip of land, which is referred to as the "working width". The working width will typically be 26 to 30 m wide, with the gas pipeline offset from the centre line to allow for construction access.

2.4.40. Access to the “working width” will be at defined points to be agreed by the Local Planning Authority and Land Owners / Land Occupiers (including existing service / utility owners). Points of access will be carefully controlled and signposted.

2.4.41. The “working width” may be increased in size adjacent to special crossings (i.e. road crossings / rail crossings/ river crossings) to provide additional working areas and / or storage for construction materials / construction equipment / construction plant. Conversely, the “working width” may be decreased in size in areas of environmental sensitivity or in close proximity to existing services / utilities.

2.4.42. During construction of the Gas Pipeline, construction activities will normally be progressed in the following order:

Pre-construction activities (i.e. fencing, hedgerow removal, land drainage schemes);

Top-soil Stripping;

Pipe Stringing;

Welding and Joint Coating;

Trenching and Laying;

Gas Pipeline Commissioning (i.e. Cleaning, Gauging, Testing); and

Permanent Re-instatement.



2.4.43. It should be noted that these construction activities will only be progressed once agreement has been obtained for access, and specific restrictions and procedures have been confirmed (with the Local Planning Authority and Land Owners / Land Occupiers).

2.4.44. Further details of construction activities will be provided in the ES.

Construction Techniques

2.4.45. In addition to the typical construction activities, special teams will be set up by the appointed Construction Contractor to undertake any works associated with road / rail / water crossings and other crossings which require some variation from the standard methods. These works are defined as “special crossings”.

2.4.46. At “special crossings”, the standard construction procedure is adapted to suit each site's specific needs, and to satisfy the requirements of the relevant authorities and Land Owners / Land Occupiers.

2.4.47. Accordingly, in addition to the more standard ‘open cut’ construction technique, typical special crossing construction techniques include:

Auger Boring;

Tunnelling; and

HDD.

2.4.48. Further details of construction techniques will be provided in the ES.

Operation

2.4.49. After full commissioning of the Gas Pipeline, it will be operated and maintained in such a manner as to keep it safe and in good condition.

2.4.50. The operation / maintenance of the Gas Pipeline will be carried out in accordance with the requirements of the Pipeline Design Standard IGE/TD/1. Protective measures inherent to the design, together with regular monitoring, will ensure that major risk to the Gas Pipeline is virtually eliminated and so unlikely to cause damage.

2.4.51. Regular monitoring is normally carried out in the following ways:

Periodic visual monitoring;

Pipeline Internal Gauge (PIG) Survey; and

Cathodic Protection monitoring.

2.4.52. Further details of operation will be provided in the ES.

Decommissioning

2.4.53. The Gas Pipeline will be decommissioned when it reaches the end of its useful life.

2.4.54. At that time detailed decommissioning procedures will be produced in line with prevailing best practice.

2.4.55. Based on current best practice, it is likely that the Gas Pipeline will be left in place and stabilised as lifting could cause a greater disturbance to the environment.

2.5. Proposed Programme

2.5.1. The proposed overall programme, comprising construction/operation/decommissioning dates, is as follows:

Start of Construction: 2015

Commissioning of CCGT Power Plant: 2017



Full Operation of CCGT Power Plant: 2018

Decommissioning (assuming 25 year operation): 2043

2.5.2. These dates have been selected to tie in with the expected timescales for the DCO decision and commercial negotiations. The construction of the above ground power line connection to the 400kV line, the gas pipeline and water pipelines is expected to take approximately one year. Construction works on the gas and water pipelines will be arranged In a co-ordinated manner to minimise the impact on landowners and the public.
