What prices are these?
Real-time locational marginal prices for ISO-NE's eight load zones, in dollars per megawatt-hour, five-minute resolution. This is the wholesale price load settles against, not a retail rate.
Why do the zones differ?
Transmission constraints. New England imports power into its load centers, and when the lines run full, Boston and Connecticut separate from the northern zones. Maine often clears cheapest for exactly this reason.
