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.

Update on the 2017/2018 Winter Reliability Program

10/18/17 update: Initial participation results posted.

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.

Requests to participate in 2017/2018 Winter Reliability Program due October 1

Market participants: Requests to participate in the Oil Program, LNG Program, or Demand Response Program are due to ISO New England Customer Service by October 1, 2017. 

Read FERC approves reliability program for winters 2015/2016, 2016/2017, and 2017/2018 to learn more about the Winter Reliability Program and why the ISO is implementing these programs for the coming three winters.

See the Winter Program Payment Rate page for details on payment rates.

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.

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.
