2018/2019 winter outlook: New England expected to have adequate resources 

ISO New England has implemented near-term changes based on lessons learned from historic cold snap

ISO New England, operator of New England’s power system, expects the region to have the necessary resources this winter to meet consumer demand, which is expected to peak at 20,357 megawatts (MW) under normal weather conditions or 21,057 MW at extreme temperatures.

However, as seen during last year’s two-week cold snap, power system operations could become challenging if demand is higher than projected, if the region loses a large generator, electricity imports are affected, or during periods of fuel delivery constraints. In those instances, the ISO could be required to implement emergency operating procedures to maintain reliability.

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

Every year, the ISO publishes the story below on the uniqueness of the Thanksgiving Day demand curve and how electricity use coincides with oven use and TV watching. But this Thanksgiving is expected to be anything but “traditional.” Expected cold temperatures are resulting in a weather forecast that would even be daunting for a typical January. Temperatures across the region are expected to approach and/or break record cold highs and lows, dating back as far as 1901. Here’s what we’re expecting (as of Nov. 21) for electricity demand compared to what was consumed last year:

A regional first: New Englanders used less grid electricity midday than while they were sleeping on April 21

Solar power also pushes past 2,300 megawatts (MW) for first time

On Saturday, April 21, 2018, the right combination of sunshine and mild weather led to light consumer demand on the high-voltage electric power system, coupled with record-high output from the more than 130,000 solar power installations in the region. The result was that midday grid demand dipped below overnight demand for the first time ever in New England.

Summer 2018 outlook: adequate electricity supplies expected

Under normal weather conditions, New England is expected to have sufficient resources to meet peak consumer demand for electricity this summer, according to ISO New England. Tight supply margins could develop if forecasted peak system conditions associated with extreme hot and humid weather occur. If this happens, ISO New England will take steps to manage New England’s electricity supply and demand and maintain power system reliability. View the press release.

Earth Day 2018: Setting regional solar and wind power records in New England

This Earth Day (Sunday, April 22)—or any day—you can learn about the role that renewables and other clean-energy resources are playing in the region by visiting ISO New England’s Key Grid and Market Stats and Grid in Transition webpages. Following are some snapshots of where the region stands, with links to learn more.

Draft load forecast indicates energy usage and peak demand will decline slightly over the next 10 years

ISO New England develops an annual projection of how much electricity the region will use every year for the next 10 years, as well as how high demand will peak during each of those years. The 10-year forecast is a key system planning tool, helping ensure New England has an adequate supply of resources to meet future demand and a transmission system that can do the job of carrying power to residents and businesses.

The draft long-term forecast for 2018 to 2027 projects that energy usage and peak demand will decline slightly in New England over the 10-year period. The primary factors are continuing installation of energy-efficiency measures and behind-the-meter photovoltaic (BTM PV) arrays throughout the region.
