BHE Montana Joins 8-Member Western Power Market as EDAM Logs $11.38 Million in Early Savings

Summary

  • BHE Montana became the eighth utility to sign onto the Extended Day-Ahead Market, widening the new Western power-sharing system launched in May.
  • The day-ahead market lets utilities and grid managers coordinate electricity trades across state lines a day in advance, aiming to cut costs and bolster reliability as demand rises and heat waves strain the grid.
  • $11.38 million in savings has already been generated in EDAM's first two months, reinforcing arguments that a larger unified market can buy cheaper power and reduce outage risks better than smaller fragmented systems.
  • The sign-on adds momentum in a regional contest with Southwest Power Pool's Markets+, as Western utilities weigh which platform to join for future cost and reliability gains.
