Update on ISO-NE study of fuel security challenges

ISO New England is conducting a study of fuel security challenges to the continued reliability of New England’s power system. In this context, fuel security refers to the ability of power plants to have or obtain the fuel required to generate electricity, especially during the winter peak season.

The study is examining more than a dozen scenarios of generating resource and fuel-mix combinations and will quantify each scenario’s fuel security risk—that is, the number and duration of energy shortfalls that would require implementation of emergency procedures to maintain reliability during the entire winter period in 2025. The study is not focused on the effects of expanded access to natural gas from the region’s pipeline network. The study is still underway, with completion expected by the end of October, 2017.

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.

Update on the 2016/2017 Winter Reliability Program

For the fourth year in a row, a winter reliability program is in effect to help augment fuel adequacy in New England. In September 2015, the Federal Energy Regulatory Commission approved a program for the winters of 2015/2016 to 2017/2018 to address seasonal reliability challenges created by constraints on New England’s interstate natural gas pipeline system. The previous programs proved to be cost-effective, short-term solutions to help keep the lights on in New England during very cold winter days.

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.
