Polish wind power plant developer and operator Polish Energy Partners (PEP) has collaborated with German engineering company Siemens for the construction of two wind power plants totaling capacity of 66.7MW.

Siemens has scheduled the delivery of 18 SWT-2.3-108 wind turbine units, each rated 2.3MW, from May 2014 for the first wind project of installed capacity of 41.4MW. The project is expected to begin commercial operations starting in the late fall of 2014.

The second wind project features 11 similar turbines and is estimated to have a production capacity of 25.3MW.

The turbine delivery for the project is likely to commence in May 2014 with commissioning expected by summer 2014.

Siemens Wind Power EMEA sales region CEO Jan Kjaersgaard said, "We are very happy that our so far experience and proven reliability have convinced PEP S.A. to choose Siemens, allowing us to make yet another major contribution to promoting climate protection in Poland."

The wind projects are said to be the first in Poland to employ rotors measuring 108m in diameter and the hub height of 115 meters above ground.

The two new wind power plants are estimated to cater to the electricity needs of some 43,000 Polish households while at the same time cutting down the greenhouse gas emissions by 140,000 tons per year.
