ISO-NE’s capacity deficiency event demonstrated the significant benefits of solar resources, along with their limits in displacing fossil resources during peak load periods.

ISO-NE and stakeholders discussed market performance, capacity auction reforms, the RTO’s 2026 budget and asset condition spending at the summer meeting of the NEPOOL Participants Committee.

ISO-NE declared a capacity deficiency, implemented a Power Caution and took extra actions to maintain grid reliability during what may have been the highest peak load since 2013, driven by extreme heat and humidity.

ISO-NE CEO Gordon van Welie has announced plans to step down at the end of 2025. He will be replaced by longtime ISO-NE COO Vamsi Chadalavada.

Asset condition costs in New England have grown by $95 million since March, according to an update to the asset condition project list presented by the region’s transmission owners.

Despite interest from the Trump administration, new gas pipelines into New England remain unlikely due to a lack of counterparties willing to pay for the new lines, energy industry experts said.

The Internal Market Monitor weighed in on ISO-NE's proposed capacity market overhaul, expressing support for increased flexibility around resource retirement notifications and recommending the elimination of the pivotal supplier test.

FERC’s resource adequacy technical conference zoomed out on the second day, June 5, with several panels examining ISO-NE, MISO and NYISO.
