A 2.5-MW inverter (Generator control unit) is ready for use in large on and offshore wind turbines. The 2.5-MW inverter uses an IGBT-based design and delivers power to the grid from permanent magnet generators (PMG). A U.S.-based OEM is expected to deploy the unit in an offshore European multi-GW wind farm under development. The 2.5-MW design supports towers with a capacity of 5 to 6 MW, and future designs with capacities over 10 MW. Furthermore, the liquid-cooled inverter uses medium voltage to reduce a customer’s footprint and cabling costs. The units are available for production and compatible with a wide range of wind turbines. The 2.5 MW inverter features medium voltage, 5,500 Vdc, to lower cabling investment. Liquid-cooling provides an industry leading density (10W/in3.) and higher reliability. A high conversion efficiency (98.5% at full load) increases power delivery to the grid, enabling higher return on investment. A modular design permits flexibility in sizing multiple inverters for wind-power generators in excess of 10 MW. Low-output voltage harmonics distortion (THD <3%) provides higher power quality delivered to the utility grid. The inverter works with photovoltaic arrays as well.

I am a senior mechanical engineering student working on a team designing a wind farm for Lake Champlain in Vermont. I was wondering how much heat the water cooling systems need to remove from these inverters and also what the price ranges for these 2.5MW inverters is.
thanks for the help,
