ISO-NE summarizes factors that contribute to curtailment of wind power during grid operations

Over the past five years, the amount of wind power connected to the New England high-voltage power grid has grown rapidly—from approximately two megawatts (MW) in 2005 to more than 700 MW today. Another 2,000+ MW of wind generation has been proposed for the region. Rapidly evolving technology, public policy goals and requirements, and government programs such as the federal Production Tax Credit (PTC) are all contributing to rising wind energy development. The growth of this resource adds to the region’s generation portfolio and can also help meet state renewable energy goals. At the same time, it is also adding new and complex challenges to managing the New England power grid.

ISO-NE now publishing seven-day wind power forecast

Currently, about 700 megawatts (MW) of wind power generation are connected to the New England electric grid. An additional 2,800 MW of wind power are in the ISO’s generation interconnection queue, representing nearly 40% of all generation projects being proposed for development in the region. The ISO is taking steps to prepare for managing the grid with an increasing amount of this resource, which has operating characteristics different from traditional resources in that the fuel—wind—is available intermittently. One major initiative underway this year is the development of a centralized wind power forecast. In May, the ISO began publishing a seven-day wind forecast for New England. Each weekday, a CSV file is made available on the ISO website that provides an aggregate wind power projection for each hour for the next seven days. The forecast is still under development and is posted for informational purposes only; the full, final forecast should be operational before the end of 2013. The forecast is already providing useful data on the expected output of wind power resources in the region.
