What is ISO-NE, and what does this page show?
ISO-NE runs the grid and wholesale market for the six New England states. This page reads its condition live: system demand, today's peak so far, generation by fuel, and the real-time price in each of the eight load zones.
How fresh is this data?
Demand and zone prices post on ISO-NE's five-minute cadence, and the generation mix updates every few minutes, all from the ISO's public feeds. /status shows every feed's age.
Why does the fuel mix matter here?
New England leans on natural gas and imports harder than any other US region. When gas gets scarce in a cold snap, oil units and the dual-fuel fleet pick up, and prices move first in real time. The stack on this page shows that substitution as it happens.
What should I watch on a hot day?
Demand against today's peak. One summer hour sets every facility's capacity tag for the following capability year, and the dashboard publishes a daily call on whether today can take the slot.
