Summary

  • $1.75 billion in estimated wholesale electricity costs for spring 2026 marked a 6% increase from a year earlier, ISO New England’s market monitor said.
  • Emissions costs for a typical gas generator surged 65% even as natural gas prices fell 18% to $2.79 per million Btu, breaking the usual link between gas and power prices.
  • Lower nuclear output from refueling outages left less-efficient generators setting prices more often, while mid-May warmth lifted electricity demand 2% from spring 2025.
  • Energy costs climbed 16% to $1.46 billion, with day-ahead prices averaging $48.41 per MWh and real-time prices $47.54; net imports supplied 13% of regional demand, up from 7%.
  • Capacity costs fell 26% to $266 million on lower cleared capacity and less price separation in import-constrained zones, partly offsetting the broader rise in power-market costs.
