ISO-NE expects sufficient power supplies this summer

New England is expected to have sufficient resources to meet peak consumer demand for electricity this summer under both typical and extreme weather conditions.

ISO New England prepares short-term forecasts for the summer and winter seasons, taking into account estimated contributions from all resources, including those with and without an obligation through the capacity market to supply electricity; unplanned resource outages; imports from neighboring regions; and resource additions and retirements. These estimates help inform ISO New England’s planning on how to operate the grid during the upcoming peak season.

2019 forecast of capacity, energy, loads, and transmission is published by ISO-NE

Energy usage and peak demand will decline slightly over the next 10 years

On May 1, 2019, the ISO published the 2019-2028 Forecast Report of Capacity, Energy, Loads, and Transmission (CELT). The report is a primary source for assumptions used in ISO system planning and reliability studies. It provides a snapshot of the New England power system, including:

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.

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.
