SPI News: ISO-NE submits proposal to strengthen performance incentives in New England’s Forward Capacity Market

Resource performance concerns driving FCM redesign

ISO New England submitted a proposal to the Federal Energy Regulatory Commission (FERC) on Friday, January 17, 2014, that provides stronger incentives for resources to undertake investments that ensure they can perform when the power grid is stressed. These changes to key elements of the Forward Capacity Market (FCM) are needed to address significant risks to the continued reliability of the region’s power grid.

Growth in solar energy means changes for power grid planning, operations

Solar energy has become one of the fastest growing types of electricity generation in New England. Based on ISO New England and available state data, more than 250 megawatts (MW) of solar photovoltaic (PV) resources were installed by the end of 2012—and approximately half of that was in 2012 alone. While this is still a relatively small amount—many conventional power plants in New England are larger than this aggregate capacity—the mounting volume and pace of solar development has prompted ISO New England to ratchet up its efforts to understand the impact this resource and other distributed generation (DG) technologies, such as cogeneration, biomass, and wind turbines, will have on the regional grid.

Ten years after the 2003 Northeast Blackout, much has changed

August 14, 2013, marks the ten-year anniversary of one of the most notable dates in the history of power system operations: the 2003 Northeast Blackout. On this day, more than 50 million people in the US and Canada lost power—and it all happened in a matter of seconds.

Heat wave pushes New England electricity use to highest peak this year

Sweltering temperatures and high humidity from July 14 through July 20 sent electricity demand soaring and set some new records for power use. At the onset of the week, ISO system operators forecasted very high demand for electricity—the highest of the season—and tight power system conditions were expected throughout the week.

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.
