This summer, we tracked peak demand, temperature, and electricity prices across New England with help from ISO-NE data. A few highlights:
- Electricity use was lower than 2025, thanks to milder average temps
- July 2 brought this year's highest demand (24,450 MW) during a holiday heat wave
- August showed how humidity — not just heat — drives demand
- Emissions from NE power plants dropped 19% compared to July 2025
