As ovens heat up on Thanksgiving Day, so does electricity demand

For many around New England, the ritual is the same: Wake up early on Thanksgiving morning and start prepping dinner, firing up ovens for turkeys, stuffing and pies. The holiday brings a lot more activity than a typical fall Thursday morning and also changes the way ISO New England plans for the region’s energy use that day.

On most fall days, electric demand peaks in the early evening, as people around the region return home and begin household chores like laundry and cooking dinner. But on Thanksgiving, ISO New England’s system operators have seen consumer demand for electricity peak much earlier – often around noon – making it the only day of the year where electricity demand peaks this early.

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.

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.

Winter 2015/2016 recap: New England power system performed well and prices remained low

Compared to winters past, the winter of 2015-2016 featured above-average temperatures and a brief cold snap in February. Many in the region have called it the “the winter that wasn’t.”

According to the National Oceanic and Atmospheric Administration (NOAA), this winter was the warmest on record in the US. The average temperature in the lower 48 states was 36.8°F, which is 4.6°F above the 20th-century average. That beats the previous record of 36.5 degrees set in the winter of 1999-2000.

New England power system performed well through winter 2014/2015

Now that the winter of 2014/2015 is one for the history books, this much we know is certain: no two New England winters are alike. A confluence of regional and global factors, advance planning and preparations, and delayed cold weather during winter 2014/2015 helped alleviate the operational issues and record-high prices seen during the previous winter.

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.
