ISO-NE publishes 2018 Regional Electricity Outlook 

ISO New England has published its 2018 Regional Electricity Outlook (REO), an annual report looking at the trends and challenges affecting New England’s power system, as well as the innovative solutions the ISO is pursuing to ensure reliable electricity for the region’s homes and businesses—today and into the future. The report describes changes to the region’s electric grid over the past two decades, and how the ISO is working to keep New England on the cutting edge as the region’s electricity industry rapidly evolves towards a future of renewable and natural gas resources.

The 2018 REO, as well as webpages that highlight and expand on information and statistics in the report, are available at www.iso-ne.com/reo.

Powering to the finish: The ups and downs of electricity demand during a Patriots Super Bowl 

What happens when the New England Patriots stage a dramatic Super Bowl comeback, erasing a 28-3 deficit and forcing overtime? Residents across the region keep their televisions on, eager to catch a glimpse of the Patriot’s latest historic victory.

During the Patriots’ fifth Super Bowl win last year, ISO New England system operators saw demand on the region’s electric grid—which had been gradually declining through the night—suddenly level off and even inch back up as the game moved into overtime. At times, demand increased by as much as 50 megawatts during overtime.

2017/2018 winter outlook: sufficient electricity supplies expected

Natural gas pipeline constraints remain a concern; final 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. The ISO’s fifth and final Winter Reliability Program has been implemented to incentivize power plants to procure sufficient fuel before winter begins. The interim reliability program is ending after this winter due to new capacity market performance incentive rules that go into effect June 1, 2018. View the press release for more information and download our winter outlook fact sheet.

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

For many around New England, the ritual is the same: Wake up early on Thanksgiving morning and start prepping dinner, firing up ovens for turkeys, stuffing and pies. The holiday brings a lot more activity than a typical fall Thursday morning and also changes the way ISO New England plans for the region’s energy use that day.

Summer 2017 recap: Cool temperatures bring lower demand, prices 

Power system operates well during summer months, partial solar eclipse

Cooler than usual temperatures during July and August led to less demand for energy-intensive air conditioning, lowering overall consumer demand for electricity during Summer 2017. The cooler temperatures and lower consumer demand led to a relatively uneventful summer, and the ISO New England control room operators were able to reliably operate the power system throughout the season, including when a partial solar eclipse reduced output from solar power resources on August 21.

ISO-NE employees recognized with INFORMS award

Several ISO New England employees have been recognized by INFORMS, a leading international association for operations research and analytics professionals, for their paper addressing the challenges associated with operating large-scale electric power systems in light of the increasing penetration of wind and solar power generation.

A collaboration between ISO New England and the Georgia Institute of Technology, the paper, “Multistage Adaptive Robust Optimization for the Unit Commitment Problem,” was recently named the INFORMS ENRE Best Publication Award in Energy, an annual award given to the best refereed journal article in the areas of energy, natural resources, and the environment.
