Regional air emissions 2017: long-term reduction trends continue 

Since 2001, SO2 down 98%, NOx down 74%, CO2 down 34%

Note: This article was updated following the publication of the final 2017 ISO New England Electric Generator Air Emissions Report.

Regional emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2) declined in 2017 compared to the previous year, according to data compiled for the 2017 ISO New England Electric Generator Air Emissions Report. The lower emissions were due largely to a decline in electricity generation by power plants that use fossil fuels. The year-over-year declines continued long-term reductions in the emissions produced by New England power plants.

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:

Earth Day 2019: A capacity market first

Every year, ISO New England fields requests from new resources seeking to enter the Forward Capacity Market. And every year, ISO analysts research those resources to ensure they’ll be able to provide the region with the capacity they’re promising three years in the future. But what happens when a resource is actually 5,000 individual power systems spread out across four New England states?

A different kind of holiday: Thanksgiving grid demand peaks in the afternoon

For the first time since at least 2000, and possibly ever, Thanksgiving didn’t see its usual morning peak for grid demand this year. The change wasn’t caused by New Englanders suddenly deciding to change their cooking habits, but rather the further influence of solar power in the region.

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.
