The public institutions in the electricity sector: • Minstry of Energy and Petrolium • Energy Comission • GridCo

– System control via national dispatch centre, Tema – Transmission system operator

• VRA – Former all-inclusive utility – Now main generating company (~85%) – Distributor in Northern Regions (NEDCo) – Head office in Tamale

• Energy Company of Ghana (ECG) – Distributor in all regions except Northern Regions – Headquarter in Accra

Background Info VRA

10

• The tradition full-services utility of the country.

• Remained as generation company after the unbundling of the electricity sector

• Operates most larger power plants (water dams, thermal units)

• The slogan: Setting the standard for public sector excellence in Africa

• Means: – Safety during works – Diligent maintenance and nothing

left in disorder – Responsibility for employees and the

energy supply of the nation


Renewable Energy Development Programme (REDP) at a glance

• Since 2010, VRA intensively develops renewable energy projects country-wide based on a formulated policy with the objective of promoting sustainable power generation through renewable energy resources.

• Referring to this policy, the company has chosen to develop – a wind farm project with a capacity of up to 150 MW and – a solar power project with a capacity of up to 10 MW

11


REDP Consultancy at a glance

• Wind Energy – Assistance in wind measuring programme; – review of feasibility studies and wind power feasibility appraisal; – design review; – contract advise; – construction supervision

• Solar Energy: – Design review (PV); – preparation of a CSP feasibility study; – pre-design and tender document preparation; – construction supervision,

• CDM facilitation for the wind and the PV solar projects; • RE Masterplan: Renewable energy development and integration planning; • Training the staff in renewable energies

12


REDP Consultancy for Solar Power

• PV – Basic design, – Preparation of tender documents, evaluation of tenders, assistance during contract

negotiations, compilation of contract documents, – Review and approval of drawings, – Project cost and time schedule control, – Site quality assurance, – Transfer of know-how and workshop, – Supervision of construction, erection and commissioning and – Services during warranty period.

• CSP – Assessment of technical options: Solar field; Site assessment; Solar resource. – Plant design including plant performance, economic analysis, – procurement and construction scheme.

REDP SPP1: Ghana‘s first MW-sized green-field PV plant at Navrongo, UE


The project in brief

• Location: East of Navrongo, UER • Project development completely by VRA • Capacity: 2.543 MWp

• Tendered in early 2011 • Awarded to CWP, China, in February 2012

• Construction started in March 2012 • Commissioning in February 2013 • Commercial operation since April 2013

• 6 months of joint operation with Contractor • Now fully under control of VRA

Factory Acceptance and review

16

• Large utility companies are used to follow established processes

• Such procedures origin from implementation of complex large scale power plants

• Usually, extensive testing and design review is included

• But is this applicable in PV projects? • Example:

– Do we always need a Factory Acceptance Test?

– Quality can be assured by sending modules to an external lab or testing on-site!

Basic Design: Concept

Characteristics: • Failure resistance by using proven components, set-ups and modularity • Well adapted to site conditions • Planned for remote operation but allowing local control • Employment of local staff for low-level activities during operation • Challenges

– Remote SCADA integration – Interconnection to single-feeder MV grid Load flow analysis and assessment of short circuit conducted The MV network can absorb the generation units and voltage stays within allowed limits.

31

Overall goal – Reliable energy output – O&M friendliness


Basic Design: Plant layout

Electrical layout • 1MWp blocks • Distributed inverters • SCADA ring • Outdoor switchyard

Civil layout • Central alley & maintenance ways • Technical area • External margins • Fence • Lights


Basic Design: Electrical system

Electrical • Modular • Straight:

240V 34.5 kV • Auxiliary systems • Monitoring &

Basic Design: Technical area for infrastructure

34

Infrastructure • Control Building • Gate house • Parking • Borehole • Waste disposal • Sewage


Basic Design: Technical room and outdoor switchyard

35

• Control & metering • Workshop & office • Auxiliary power: hybrid supply via trafo, backup, PV • Spare parts & workshop • Facilities


Basic Design: SCADA integration & grid connection

36


Expected cost share and commercial set-up

• Expected installation price similar typical to typical PV greenfield installations but the contract will include interconnection works, SCADA integration, O&M facilities and training amongst others.

• O&M – To be conducted by VRA – Contractor to provide remote support

• Contract model – FIDIC Yellow Book – VRA Engineering Services as Engineer

• Time Line – Award of Contract by end of Q2/2014 – Time for Completion: 11 months

Not like to typical investor driven projects Plants are to be regarded as part of the national

energy infrastructure!
