Cape Wind reports its scientific data tower has recorded strong winds on Horseshoe Shoal in Nantucket Sound during each of the past 10 record electric demand days in New England. These results are available in a new report published by Cape Wind titled ‘Comparison of Cape Wind Scientific Data Tower Wind Speed Data with ISO New England List of Top Ten Electric Demand Days.’
The report finds that Cape Wind would have produced an average of 321 MW when electric demand was at its peak during each of the past 10 record-setting electric demand days as recorded by the Independent System Operator of New England (ISO-NE), the region's electric grid manager. According to the report, nine of these record demand days have occurred on hot afternoons in the summers of 2006 and 2005, and one occurred June 27.
Production of 321 MW during these times of record electric demand represents 76% of Cape Wind's maximum potential of 420 MW and is 76% greater than Cape Wind's average expected output of 182 MW.
Len Fagan, Cape Wind's vice president of engineering, explains that Cape Wind's production would be higher during these hot summer afternoons due to a sea breeze effect that occurs on ‘the hottest summer days when the air over the land heats up faster than the air over the ocean.’
