The Fântânele-Cogealac Wind Farm is the largest onshore wind farm in Romania, with installed nameplate capacity of 600 MW from 240 General Electric 2.5xl wind turbines.[1] The wind farm has been built for the ČEZ Group.


The project was first envisioned by United States, Delaware corporation Continental Wind Partners or (CWP) a renewable energy partnership backed by private equity fund Good Energies Investments with operations in several countries including Romania, Bulgaria, Poland, Australia and New Zealand.[2] In 2008 Continental Wind Partners agreed to sell the 600 MW wind farm project to the Czech energy utility ČEZ Group for an undisclosed sum.

Planning permission was granted in 2007 and construction began in September 2008, with the first turbine being erected by August 2009. The first stage of the project, the Fântânele farm, was finished in December 2010 with the erection of 139 turbines. The second phase of the project involved the construction of another 101 wind turbines erected in Cogealac and has a nominal power output of 252.5 MW and was completed in November 2012.[3]


The wind farm occupies Script error: No such module "convert". of open field, Script error: No such module "convert". in Fântânele and Script error: No such module "convert". in Cogealac communes.[3] The wind farm is being constructed north of Constanţa, Script error: No such module "convert". west from the shore of the Black Sea.[4]

The entire project required a capital investment of approximately €1.1 billion.[5] Fântânele-Cogealac wind farm is the largest onshore wind farm in Europe surpassing the 322 MW Whitelee Wind Farm in Scotland, United Kingdom.[6][7] The wind farm will account for 10% of the total green energy production in Romania at completion.[8]

As the figures given above were published before the turbines had been operational for a full year they are projected rather than recorded figures. Wind speed is not constant, therefore, a wind farm's annual energy production never achieves the sum of the generator nameplate ratings multiplied by the total hours in a year. The ratio of actual productivity in a year to this theoretical maximum is called the capacity factor. Typical capacity factors are 20–40%, with values at the upper end of the range achieved on particularly favourable sites.[9][10] The expected capacity factor for Fântânele-Cogealac Wind Farm, calculated from the company's projected figures, is 30%.[original research?]


The wind farm was planned to be constructed in two phases in Fântânele and Cogealac on an area of Script error: No such module "convert"..[3] The construction of the first phase of the wind farm on a Script error: No such module "convert". plot of land started at Fântânele in October 2008 with the construction of Script error: No such module "convert". of access roads as well as the foundations for the wind turbines leaving a distance of Script error: No such module "convert". between them.[11] The land on which the wind farm is built is partially owned by the CEZ Group but most of it is leased for a period of 49 years from local land owners, who receive around €3,000 per year each in royalties.[8] For the connection of the individual turbines and the transportation of electricity Script error: No such module "convert". of cables were laid.[12] CEZ also commissioned Siemens to build four electric power transformation substations that are used to increase the voltage from 33kV to 100 kV and one main transformation station used to further increase the voltage to 400 kV so it can be suitable for use by Transelectrica, the national electric power transmission company of Romania.[13] For the construction of the Script error: No such module "convert". of roads 950,000 tonnes of crushed rock was used, and for the construction of a single wind turbine foundation 40 tonnes of rebar and 400 cubic metres of concrete were used as well as 105 pilings used to stabilise the structure driven into the earth at depths of up to Script error: No such module "convert"..[4] All of the infrastructure from the site was designed and constructed by a joint venture Viarom Construct SA -roads and concrete foundations- and Energobit SA -electric cabling and electric substations-.

The components of the wind turbines used at Fântânele are manufactured in Brazil, Spain and Germany for the blades, the nacelle, in Germany and the tower segments were produced in Germany and China and the United States for the electric and electronic component.[4] According to the rhythm of construction as much as 50 trucks enter and leave the site on an average day transporting around 8,000 tonnes of materials on a weekly basis, but figures were as high as 10,000 tonnes per day at the beginning of the construction.[4] For the assembly of the wind turbines giant cranes are used with lifting capacities between 500 and 700 tonnes.[4] The Fântânele wind farm was expected to cost around €600 million.[14] The first wind turbine at Fântânele to be connected to the national grid was commissioned on 1 June 2010 having the number FE-28.[15]

The construction of the second phase of the wind farm on a Script error: No such module "convert". plot of land at Cogealac started in 2010 but was postponed due to issues and conflicts with the mayor of Cogealac, Cati Hristu.[14] This phase included the erecting of 101 General Electric 2.5xl wind turbines with a nominal power output of 252.5 MW.[11] The Cogealac wind farm involves capital investments of around €500 million and was complete in November 2012.
