Montana: The Boom and Bust of a PURPA Market

by Colin Smith

The Montana Public Service Commission (MT PSC) recently ruled to temporarily suspend NorthWestern Energy’s standard rate contract for qualifying PURPA projects. With no other factors driving utility PV in the state, the decision has effectively frozen the growth of utility solar in Montana. This new brief discusses the current state of Montana's utility solar development pipeline.

This briefing is exclusively provided to Utility PV Market Tracker subscribers. GTM Research will continue to monitor the rollout of a new standard rate over the coming months.
