Wind farms Tulcea South

Tapping the potential of green energy, opens the gates for achieving real strategic objectives regarding energy safety consumption trough diverse sources and diminishing imports of foreign energy, thus developing a durable energy production sector and protecting the environmental.The safety issue regarding energy consumption is assured by taking in consideration the imports, in a context of energy market liberalization and in agreement with the urgent need of diminishing the environmental impact on our planet.

In The Green Card To an European strategy for safety in energy distribution is stated that renewable energy sources can contribute to the growth of internal resources, making them a high priority in energy politics.

On a global scale, it is noticed a growing concern from the European Union regarding promoting strategies for renewable energy resources, wind energy being mentioned as well. In particular, it is being noticed in Europe, and on a global scale as well, a tendency to invest in wind energy production and in the technology and research activities concerning this domain. This makes a new market for work force, which is most wanted, taking in consideration the actual economic status.

The tendencies in all industrialized states are to harness the wind for energy production purposes. Because the wind is a clean and limitless energy resource, the wind turbines are planted where wind speed and intensity are most suitable for them to supplement conventional energy sources.In the last 5 to 10 years many European governments developed strategies to promote renewable energy resources and defined incentives for its growing demand. In the last 20 to 25 years, wind farms deployment had changed fundamentally. If in the beginning the wind farms with a power between 100 kW and 800 kW were predominant and wind farms were built rarely, after year 2000, the most wind harnessing equipments are grouped in wind farms numbering 20 or more clusters. Nowadays, the deployed power in such a cluster varies between 1.5 and 6 MW, the majority of projects deploying capacities up to 2.5 or 3.0 MW per turbine depending on the wind potential measured in the area and the variation of the power curve reporting to wind speed. Thus, if an area has a lower potential than another, it is recommended to use a wind turbine model that has a lower starting speed.

Europeans Union objective is to have 20% of it used energy provided by green energy resources until 2020 and until 2030 the percentage is to rise until 28.5%. If in 2010 there were only around 85 GW, the EU objective until 2020 is to install around 230 GW, and until 2030 around 400 GW. To capitalize the true potential of wind energy it is necessary to diminishing the costs, to deploy more wind farms out to the sea and to resolve the problems regarding the integration to the nominal grid.

For this to be done it is necessary to obtain a much clear image of wind resources in Europe through a well coordinate campaign of measurements and viability testing of some new logistic strategies and technologies to build turbines in some remote and climatic averse areas. All these must be implemented in a complex research program aiming to upgrade the production output of wind turbines.

Using wind energy in RomaniaAccording to statistics, Romania has the biggest potential for wind energy from South-East Europe. A study conducted by Erste Bank places our country, and especially Tulcea and Constanta Countys, on the second place at European level for the best suitable place to deploy a wind farm.

At the beginning of 2010, Romania had less than 460 MW deployed in wind energy and on 30.03.2014 , according to ANRE reports, in Romania there were 2900 MW in wind energy, 1100 MW in photovoltaic energy and 400 MW in micro hydro-centrals .

Since Romania entered EU, the efforts are constant and the commitments referring renewable energy production are as follows:- by 2020 , the electric energy provided by renewable energy sources to represent 38% of the total national consumption ( wind farms, photovoltaic , hydro-centrals and micro hydro-centrals).

The wind speed distribution on Romania territory demonstrates that the main area with high wind potential is represented by the mountain peaks, where wind speed may exceed 8m/s.The second area with more than acceptable wind potential is the seaside, DanubesDelta and North Dobrogea where the yearly average wind speed is situated between6-7 m/s. Unlike other areas, here, the exploit of wind energy is favoured by low wind turbulence.The third area with a notable wind potential is Podisul Baraganului (Baraganssteps), where average wind speed is registered at 4 m/s at 10 m altitude.

Thorough studies showed up that for an investment to be profitable in this domain, which means to recuperate you invested money in a reasonable amount of time, average wind speed must reach at least 4 m/s at 10 m above ground.

At this moment, wind turbines have their rotors at 80, 100 and even over 120 mabove ground, not only for tapping the winds true potential, but also because at thisaltitudes there are less turbulence.

Figure 2.1: Romanias wind potential chart

WIND PARK SOUTH TULCEAAccording to the research project financed by the EU and coordinated by EWEW , Romania is situated on the third place in Europe regarding the speed with which an approval for wind farm deployment can be obtained. Thus, in Romania, 15 months are needed to obtain these approvals, the European average being 42 months. The plug in aspect of these wind farms must be kept in mind as well, regarding the network of transport and distribution. This generates problems that are more severe than the ones discussed earlier and stand for much higher cost. So, for these projects to be implemented, it is needed not just an coherent strategy to encourage investments in this domain of energy production, but also investment in transportation and distribution of energy must be taken in consideration as well.

In picture 2.1 shown above, a wind chart for Romanias wind potential is presented. Here are compiled the results given from a height of 50 m, on ideal conditions of earths surface.The levels of interest in wind energy start from very good sites down to unqualified ones, the resource being given by yearly average wind speeds (m/s), but also by the average obtainable energy (W/m2 of rotor area, measured as a projection on a vertical plane on the plots surface).This map has a highly grade of generalization and even if it permits us to obtain valuable info's, these have at this certain level a general character. The costs implemented in green energy resources with the aim to produce electrical energy are diverse, being related to the nature of the resource and the technologies being used.

During the last period of time a higher interest is shown in the development of wind farms, this being stimulated by the mandatory transactions of green certificates. In this sense, Romania offers generous packages for such investments. Law no. 220/2008 with its afterward changes, regulates the support package of energy stations from renewable sources. Thus, according to Law 220/2008, all energy stations that produce from renewable sources, receive green certificates for 15 years for each MW introduced in the National Energy system, as following: a) 6 green certificates for each MWh produced by photovoltaic station.b) 3 green certificates for each MWh produced by micro hydro-centralsc) 2 green certificates for each MWh produced by wind stations until 31.12.2017 and 1 green certificate up to 15 years.

According to this Law, for an energy stations to be granted with green certificates, the station has to be operational until 31.12.2016. In the same time, according to the Law, the number of green certificates can be reduced if the internal return of the electric station increases over 11% ( mainly as a consequence of the cost reductions with the investment) , thus avoiding over compensation.

Regarding this, all the wind farms operational starting with 01.01.2014, will receive green certificate as it follows: a) 3 green certificates for each MWh produced by photovoltaic station.b) 2.3 green certificates for each MWh produced by micro hydro-centralsc) 1,5 green certificates for each MWh produced by wind stations until and 0,75 green certificate up to 15 years.

Tulcea County takes advantage of some of the best conditions for developing efficient investments regarding the production of renewable energy through:- tapping into the wind potential of the area;- taking advantage of the technical infrastructure in the area:a. high voltage electrical lines LEA 750 kV LEA 400 kV;b. national, regional, communal and agricultural roads;c. free agricultural plots, ready for development.

The commitment Romania took for a rapid growth in renewable energy evolution defined the purpose for a handful of commercial entities (commercial societies) to develop one of the biggest wind farm in Dobrogea region with a highly complex profile so that the best wind conditions are to be guaranteed.

The targeted area is South of Tulcea County, in Baia, Beidaud, Casimcea, Stejaru, Topolog, Daeni and Ciucurova.

The table below shows the wind farms description with the following information:- the name of the company which manages the project,

- the project name,

- the number of wind turbines proposed and approved on the sites,

- the installed power approved on each wind farm:

5 X 2.50

The initiators of these projects are limited liability companies among which a cooperation agreement was signed (signed on 15 November 2011 - Annex) for connecting the entire wind farm complex to the power grid in a unitary solution.The location of the wind farm complex was based on specialized technical

studies:

- topographical studies,

- geotechnical studies,

- wind studies,

- environmental impact studies,

- urban studies - Phase urban zonal plan (PUZ),

- studies of solution for connecting wind farms to the national power grid,

- specialized studies of the cultural heritage.

PUZ urban documentation phase were conducted in accordance with the laws in force and were approved by decisions of local councils of villages which are located, within the validity period of 4 to 5 years, expiring in the period between June 2016- February 2018.Each wind farm has provided locations for each wind turbine installation, assembly platforms, necessary operating roads and the substation for power grid connection.Urban plans (PUZ) were made taking into consideration wind turbines whose dimensions are specific to V112 Vestas wind turbines (3MW) and Gamesa 136 wind turbines (4.5 MW). On this given moment, Vestas started producing V112 3.3 MW wind turbines and Gamesa started producing G 128 5 MW. Both models did not suffer any dimensional changes. Thus for wind farms authorization you will be able to use any type of turbine without having to change planning documentation and other equipment and utilities of the wind farm.

The land (on which was designed the placing of the wind turbines) were employed superficies contracts for a period of 49 years. The contracts were signed and notarized between landowners and each wind farm company. For each wind farm, agreements and permits for operational use of municipal and county roads, have been obtained from the competent authorities.The review of the connection to the national energy system (SEN) was based on a solution study for connecting the wind farms complex, study which has been analyzed in CTES - EEC Dobrogea. The CTES approval no. 304/3011 has opted for the connection solution: INPUT-OUTPU 750 kV in OHL ISACCEA-STUPINA transformer station called Rahmanu 2 Station.The Rahmanu 2 Station will provide wind farms complex (Tulcea South) connection to the 750kV line and has an estimated value of approx. 53.8 million euros. The connection costs will be individualized for each wind farm. The transformer station will be treated as a separate objective, but technically and financially connected to the entire investment project as a whole. The land required for the station was bought by us, and urban plan area documentation (PUZ) was also approved. The following investment planning stages for each wind farm is conditioned by specifying the type and technical characteristics of wind turbines which will be used by the investors.The design phase of the project can be covered by us with the investor who decides to purchases the project.. Completion of design and obtaining building permits can be achieved in a maximum of 6 months from the signing of a collaboration contract with the investor and after the investor decides which type of wind turbine it will utilize in this project.

Based on the feasibility studies an estimated cost evaluation for the 1200 MWwind farms complex was made:

To start the construction works authorization and funding stages should be completed. Technical projects for each wind farm are ongoing (documentation for obtaining environmental agreements, detailed geotechnical for each site, technical projects for roads, platforms, substation and connection units, documents for land to be affected by construction).We believe that funding can be achieved in the following steps:

- Turbine-type decision for each park and launch design work to obtain building permits;- obtaining building permits each wind farm;

- building permits for input-output transformer station in OHL 750kV - Rahmanu 2;

- financing achieving the input-output station 750 kV OHL Rahmanu 2;

- financing the construction of wind farms in block or separately building works and equipment.In the development of this investment can participate more investors.

The investor will buy shares from the wind farms companies in evolutionary stages of the projects. Our intention is to provide support to the investor during the building process until the wind farms are built and running.From the analysis of the overall project, an effective strategic approach should consider the investment and building program upon which to realize in the first stage the input and output transformer station in the national energy system by LEA-750 kV - Rahmanu 2 station. (For which all technical project start-up conditions, obtaining building permits and start construction works are ready to go).
