New England is expected to have the resources needed to meet consumer demand for electricity this summer, though tight supply margins could develop if forecasted peak system conditions occur. If this happens, ISO New England will take steps to manage New England’s electricity supply and demand in real time and maintain power system reliability. 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 26,482 MW megawatts (MW). Extreme weather of 94°F could push up electricity demand to 28,865 MW. View the press release.

ISO-NE marks Earth Day 2017 with an update on the effects of clean-energy initiatives in New England
This Earth Day (Saturday, April 22)—or any day—you can learn about the role that renewables and other clean-energy resources are playing in the region by visiting ISO New England’s Key Grid and Market Stats and Grid in Transition webpages. Following are some snapshots of where the region stands, with links to learn more.
Every year, ISO New England develops a projection of how much electricity the region will use and how high demand will peak during each of the next 10 years. The 10-year forecast is a key system planning tool, helping ensure New England has an adequate supply of resources to meet future demand, and a transmission system that can do the job of carrying power to residents and businesses.
The draft long-term forecast for 2017 to 2026 projects that energy usage will decline slightly in New England and peak demand will remain flat over the 10-year period. The primary factors are continuing robust installation of energy-efficiency measures and behind-the-meter solar arrays throughout the region, as well as a slightly lower forecast for economic growth in New England.
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.
How the ISO uses weather forecasts in formulating electric demand estimates
Earlier this summer, on July 7, 2016, a cold front moved into New England from the north, leading to unexpectedly cooler temperatures across the region. Boston hovered in the mid-60s for most of the day. An unanticipated thunderstorm in Hartford caused a quick and dramatic drop in temperatures. The cool weather lasted through July 8.
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.
