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.

One factor rises above the rest when accurately predicting future energy use: the weather

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.

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.

New ISO-NE webpage highlights the growing impact of solar power across the six states

Heat maps and load profiles illustrate solar power’s growing effects on the regional power system and grid operations

ISO New England is pleased to announce a new webpage, Solar Power in New England. Explore how solar power capacity is expected to grow, see how it’s already reducing the amount of electricity demanded from the grid at certain times of day, and learn why this creates challenges for ISO forecasting and grid operations.

Long-term forecasts: Electricity usage will remain flat and peak demand is expected to grow slowly

ISO-NE has published its annual CELT, energy efficiency, and PV forecasts

ISO New England has published its 2016-2025 Forecast Report of Capacity, Energy, Loads, and Transmission (CELT), a primary source for assumptions used in ISO system planning and reliability studies. It provides a 10-year snapshot of the New England power system, including the total generating capacity of resources in the region, the breakdown of the region’s generators by fuel type, a link to the list of transmission projects proposed, planned, and under construction to ensure system reliability, and the long-term forecast for growth in energy use and peak demand. ISO New England’s long-term forecast for electricity use is developed each year using state and regional economic forecasts, 40 years of weather history in New England, and other factors. The CELT also includes results from the ISO’s latest energy-efficiency (EE) forecast and solar photovoltaic (PV) forecast, which project the load-reducing effects of EE resources and “behind-the-meter” PV resources connected at customer sites to local distribution systems.

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.
