How a Patriots Super Bowl affects the region’s power grid

The New England Patriots are back in the Super Bowl, set to take on the Atlanta Falcons Sunday night in Texas. Millions of football fans across the region will be watching, and so will ISO New England system operators—not to cheer on the home-town favorite, but to ensure the region’s power grid reliability. Even when the game is thousands of miles away, the Super Bowl can have a big impact on regional electricity demand—before, during, and after the game. Like players celebrating in the end zone after a touchdown, demand spikes and dips throughout the game. Grid operators must closely monitor the fluctuations and be ready to respond quickly. Electricity supply must be kept in precise balance with consumer demand at all times—and failure to do so could result in grid instability.

2016/2017 winter outlook: sufficient electricity supplies expected

Natural gas pipeline constraints remain a concern, Winter Reliability Program implemented

Electricity supplies should be sufficient to meet New England’s consumer demand for electricity this winter, but possible natural gas pipeline constraints could limit electricity production from natural gas power plants. A Winter Reliability Program has been implemented to incentivize gas and oil-fired power plants to procure sufficient fuel before winter begins. View the press release.

Summer 2016 recap: Uneventful, until August

Summer 2016 was fairly uneventful until August arrived with its long stretches of hot, humid weather that pushed up demand for air conditioning and the electricity that powers it. Despite a high number of unexpected resource outages on one August day, ISO New England’s control room operators were able to operate the power system reliably that day and throughout the summer.

New energy-storage options emerging in New England; ISO-NE publishes primer and makes FERC filing on market participation

June 22 update: Information added on ISO-NE’s May FERC filing. Proposed project megawatts (MW) were also updated to reflect the withdrawal of 50 MW of battery storage to have been included as part of a proposed new natural-gas-fired generator.

For the first time, grid-scale (or utility-scale) battery storage projects are seeking to join New England’s regional power system. Late last year, three projects with a combined 94 megawatts (MW) in nameplate capacity applied for interconnection in Maine, with one planning to go live by the end of 2016 and the other two in 2019.*

ISO-NE incorporates wind-powered resources into real-time dispatch with Do Not Exceed Dispatch Project

The change helps improve price formation in the markets and marks an important milestone in ISO New England’s efforts to efficiently integrate renewable resources

On May 25, the region’s wind-powered resources and intermittent hydro resources began taking electronic dispatch instructions from ISO New England for the first time and became eligible to set real-time prices in the wholesale electricity marketplace. These changes were effected by the Do Not Exceed (DNE) Dispatch Project in which the ISO worked with stakeholders to implement a modified electronic dispatch method for these intermittent resources. The new system is expected to improve price formation in the marketplace and system use of low-cost renewable resources in areas with limited transmission capacity by:

2016 summer outlook: sufficient electricity supplies expected

Some natural gas generators may need to get their fuel from other sources during pipeline construction

Under normal weather conditions of 90 degrees Fahrenheit (F), electricity resources should be sufficient to meet consumer demand this summer, with a forecasted peak of 26,704 MW megawatts (MW). Extreme weather of 94°F could push up electricity demand to 29,042 MW. Construction work on the region’s natural gas pipeline infrastructure will require some power plants to obtain fuel from different sources. View the press release.
