Regional air emissions 2017: long-term reduction trends continue 

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

Regional emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2) declined in 2017 compared to the previous year, according to preliminary data compiled for the draft 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.

ISO-NE analyzes potential impact of offshore wind during historic cold spell

Acting on a request from the Massachusetts Clean Energy Center (MassCEC), ISO New England recently released a high-level assessment of the potential impact of offshore wind on the region’s power system during the historic cold snap from December 24, 2017 to January 8, 2018.

ISO-NE CEO gets “revved” up over the hybrid grid at Renewable Energy Vermont (REV) conference in Burlington

The New England electric grid is evolving in two fundamental ways, according to ISO New England CEO Gordon van Welie. The grid is shifting from the use of fossil fuels to generate electricity to cleaner resources and from central power plants to distributed generation. This change is creating a massive and exciting engineering and market design challenge, van Welie said.

van Welie shared this observation, and many others, during a keynote address at the Renewable Energy Vermont (REV) conference in Burlington, Vermont, on October 18. During his address to approximately 500 people, van Welie discussed the journey that New England is on in terms of energy policy, and the role of the ISO in it.

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.

Winter 2017/2018 recap: Historic cold snap reinforces findings in Operational Fuel-Security Analysis

Weather always plays a crucial role in how ISO New England operates the region's power grid, and that was certainly the case as New England faced a historic two-week cold snap in late December and early January that sent temperatures plunging and nearly pushed the bulk power system to the brink.

"The cold temperatures, together with winter storms and other complicating factors, led to some of the most challenging conditions our system operators have ever had to navigate," said Peter Brandien, ISO New England's vice president for system operations.

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.
