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.

New England power grid operations during August 21 partial eclipse 

Three factors tempered the effect of the eclipse on electricity demand and PV output

New England was partially under the shadow of the moon on August 21 between about 1:20 p.m. and 4:00 p.m. The region reached peak obscuration at 2:44 p.m., when about 65% of the sun was blocked. The ISO was prepared for a drop in output from the region’s 2,000 megawatts (MW) of solar photovoltaic (PV) systems and subsequent rise in electricity demand on the grid. The vast majority of New England’s solar power comes from small-scale, distributed systems connected directly to homes and businesses or to local utilities—and not to the regional power system. These systems reduce the amount of electricity demand system operators see on the grid when the sun is up

ISO-NE marks 20th anniversary

This year marks the 20th anniversary of ISO New England, commemorating two decades of reliable grid operation, the development and administration of new competitive wholesale electricity markets, and planning for the long-term reliability of the system.

Since its creation on July 1, 1997, ISO New England has been a stable presence in an ever-changing energy industry landscape. Learn more about New England's industry progress over the past 20 years and read the press release.
