Winter 2017/2018 recap: Historic cold snap reinforces findings in Operational Fuel-Security Analysis

Weather always plays a crucial role in how ISO New England operates the region's power grid, and that was certainly the case as New England faced a historic two-week cold snap in late December and early January that sent temperatures plunging and nearly pushed the bulk power system to the brink.

"The cold temperatures, together with winter storms and other complicating factors, led to some of the most challenging conditions our system operators have ever had to navigate," said Peter Brandien, ISO New England's vice president for system operations.

Power Systems Update: New England grid operations through recent bitter cold weather and preparation for winter storm

January 7 Power Systems Update 

As of Sunday, January 7, New England’s bulk power system continues to operate reliably during this extremely frigid weather covering New England and the Northeast. Nevertheless, managing the region’s power system through these conditions continues to be challenging, primarily because of fuel availability.

2017/2018 winter outlook: sufficient electricity supplies expected

Natural gas pipeline constraints remain a concern; final 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. The ISO’s fifth and final Winter Reliability Program has been implemented to incentivize power plants to procure sufficient fuel before winter begins. The interim reliability program is ending after this winter due to new capacity market performance incentive rules that go into effect June 1, 2018. View the press release for more information and download our winter outlook fact sheet.

Update on the 2017/2018 Winter Reliability Program

6/11/18 update: Final program values posted. Please note that the number of program oil barrels used differs from the actual amount of oil burned regionally because participation is capped for each participating generator. Additionally, not all generators participate in the program. Read "Winter 2017/2018 recap: Historic cold snap reinforces findings in Operational Fuel-Security Analysis" to learn how the winter reliability program has provided critical support again this winter.

For the fifth year in a row, a winter reliability program is in effect in New England to address seasonal reliability challenges created by constraints on New England’s interstate natural gas pipeline system. The program is a short-term, cost-effective effort to help ensure eligible generators have the fuel needed to operate reliably during very cold winter periods.

Winter 2016/2017 recap: Power system performs well during generally mild weather

New England’s power system performed well during winter 2016/2017, though colder temperatures in December led to higher natural gas and wholesale electric prices compared to the prices seen during the record-setting warm weather of winter 2015/2016.

While January and February were milder than normal, temperatures in December 2016 averaged 32.4°F, more than 10°F colder than the previous December. Over the course of the winter New Englanders used 30,933 gigawatt hours (GWh) of electricity, slightly less than the 31,328 GWh used during the previous winter (which, as a leap year, included one extra day in February), but significantly less than the 33,709 GWh used during the much colder 2014/2015 winter, according to ISO New England data.
