    GE’s Brilliant Wind Turbine — Wind Power Cheaper Than Coal Or Natural Gas (Part 2)

    GE’s Brilliant Wind Turbine — Wind Power Cheaper Than Coal Or Natural Gas (Part 2)

    June 30, 2013 Andrew

    This is Part 2 of a 3-part series on GE’s Brilliant 1.6-100 wind turbine. Read Part 1 here, and keep an eye on CleanTechnica or our GE Brilliant Wind Turbine archives for Part 3.

    Lower Cost Wind Energy + New Revenue-Generating Opportunities

    The GE Brilliant 1.6-100′s Ramp Control, Predictive Power Analytics, and short-term, grid-scale battery storage capabilities open up new revenue-generating opportunities for wind farm operators, enabling them to sell into regional grid operators’ frequency regulation markets. Explained Lindsay Theile, renewable energy communications leader for GE Power & Wind,

    Because batteries perform so much quicker than thermal generation, they [wind power producers] should receive a multiplier to current prices – up to 1.9-times current prices.

    Market prices for frequency regulation on regional transmission organization (RTO) PJM’s power grid recently reached as high as $14.92 per megawatt-hour (MWh) from January to October 2012, $36.52/MWh from October to December 2012, and $33.87/MWh from January to March 2013, Theile pointed out.

    Using the Brilliant 1.6-100′s integrated battery storage capabilities means wind farm operators can balance the wind-generated electricity they produce with grid load at under $1 per megawatt-hour, according to GE Power & Water. Moreover, the system’s “advanced forecasting algorithms and a small amount of short-term storage dramatically reduces the need to carry spinning reserves and frequency regulation for wind power,” Longtin added.

    When it comes to battery chemistry, GE Power & Wind is agnostic, he explained. The sodium-nickel chloride GE Durathon batteries incorporated in the Brilliant 1.6-100 prototype at Tehachapi can range from 20–70 kilowatt-hours (kWh) in energy capacity, about 2.5 kWh per turbine. GE and wind farm operators might choose to install alternative batteries, such as Li-ion batte
