The wind farm consists of 52 wind turbines with total capacity of 156MW; the windmills have been included in the National Electric Company's network.  In our country St. Nikola is the biggest wind energy park in Bulgaria, which is situated near the seaside resort of Kavarna. "St. Nikola will double Bulgaria's wind power production. The country will decrease the carbon emissions by 300,000 tons a day which is equal to 6 million tons for the 20 years of exploitation," said Bulgarian’s prime minister.

Saint Nikola Wind Farm is situated on the land territory of the villages Bulgarevo, Hadzhi Dimitar, Poruchik Chunchevo and Sveti Nikola belonging to Municipality of Kavarna. It covers an area of 60 km². The project consists of 52 turbines connected to the wind farm’s substation by 33 kV underground cables with total length of 65 km. By means of a 110 kV connecting power transmission line the electricity produced is transmitted to the electricity grid of Bulgaria. 

52 Wind Generators Vestas V90 3.0 MW with active control of the blade angle and rotor position according to the wind speed and direction in order to optimize the electricity production. The wind generators also provide the opportunity for remote monitoring and control from centralized control room. They are of modern design that includes cylindrical tower, rotor with 3 blades and the nacelle, which hosts the generator, the transformer, the gear box, and the other operational installations. The height of the towers is 105 m and the rotor diameter is 90 m.

 33 kV underground cables The individual turbines are grouped in branches and are connected through an underground cable grid that consists of 65 km of cable routes. In order to achieve the project standards and minimize the transmission losses the grid is designed at 33 kV.               

33/110 kV Substation The electric energy produced by the turbines through the underground cable grid is delivered to Saint Nikola 33/110 kV step up substation. The substation is equipped with automated and control systems that meet the highest operational standards.

 5.2 km of Power Transmission Line 110 kV The high voltage transmission line consists of 35 electric pylons supporting power cables that connect the wind farm with the national electricity system.

Many people don't want change because they don't understand how serious greenhouse gas pollution is.

Not all is lost though"In 2007-2008, when we began to study investment opportunities, the field of renewable energy appeared full of opportunities despite the risks and challenges". This was by the American entrepreneur Kenneth Lefkowitz who has been active in the Bulgarian economy for two decades and vice president of the Association of wind energy producers in Bulgaria. He also said "At the time, it was an underdeveloped sector. However, there were good prospects thanks to the objectives of 'Europe 2020', which required Bulgaria to make progress in the development of green energy."

Bulgaria, leader in South-east Europe

The boom in renewable sources allowed Bulgaria to reach the share of green energy (not just electricity) on the total consumed, fixed by the EU at 16% by 2020, eight years in advance. According to the Bulgarian Institute of Statistics, the share had already been exceeded (16.3%) at the end of 2012 – a result that only Sweden and Estonia can claim so far.
 And that is great news, however green energy isn't cheap and Bulgaria remains one of the poorest members of the European Union, the rise of the bills led to social tension which peaked in February 2013, when the centre-right government – led by the charismatic Boyko Borisov – was forced to resign because of street protests against the "crazy bills".
 Green energy and Bulgaria have this interesting "Love-hate" relationship, we all want renewable energy, but no one wants to pay for it

It is obviously a serious problem that needs a solution and Bulgaria's plan is to completely transform the energy model. The country's goal is to shut down all traditional sources of energy by the year 2040, that might sound very ambitious but it is quite feasible due to the country's size and low energy consumption.
