The contract will be financed by the China Development Bank. It is part of a number of commercial agreements made between Chinese and Turkish companies following the visit of Turkey's prime minister Tayyip Erdogan to Beijing.
This is the second major deal for Sinovel in the region. In November, Sinovel's president Han Junliang agreed a deal with Greece's Public Power Corp (PPC) to develop a 300MW project at Rodopi, in northern Greece.
In 2010, Agaoglu Energy Group stated it planned to become one of Turkey's top ten private-sector power producers by 2015. It said it planned to invest around €1.5 billion in building 1GW of installed capacity, split as evenly as possible between wind, hydro and thermal generation.
Market participants agree 2012 will be a busy year for Turkey's wind-energy sector, but are divided as to whether or not that will translate into a major boost in installed capacity for the industry.
Figures from the country's Energy Market Regulatory Authority (EMRA) showed installed wind capacity rose by 521MW to 1,799MW last year. Looking beyond 2012, however, investors agree that the market framework needs to be improved if Turkey is to come close to fully exploiting its ample wind resources.
