ISO-NE experienced record-low demand on Easter Sunday because of mild temperatures and high behind-the-meter solar output, making 2025 the fourth consecutive year ISO-NE has set a low-load record.

After writing 90 columns over 10 years, Steve Huntoon looks back at what he might have gotten right or gotten wrong.

California's duck curve deepened to new levels this spring as solar capacity increased, at times exceeding demand, the Energy Information Administration said.

ISO-NE said that last Sunday demand on the grid was the lowest it had ever recorded since the RTO began operations in 1997.

Competitive Power Ventures’ proposal to revamp ISO-NE's financial assurance rules failed to win approval from NEPOOL’s Participants Committee.

With grid challenges looming and lithium in short supply, California is looking to accelerate the deployment of non-lithium-ion long-duration storage.

Last year's events in Texas, and the growth of renewables on New England's grid, have ISO-NE and states looking at weather more closely than ever.

The phenomenon known as the duck curve is becoming increasingly common in New England, a sign that the solar energy is growing rapidly in the region.
