Colorado’s investor-owned utilities must compare available alternatives when asking regulators for approval to participate in an RTO or ISO, but not to join a day-ahead market.

Xcel Energy says it relies on industry best practices and its own experience in beefing up wildfire mitigation plans.

SPP filed bylaw amendments at FERC to place seven Western entities under its tariff that, if approved, will make the RTO the first grid operator with markets in both major interconnections.

Tri-State CEO Duane Highley spoke with ACP CEO Jason Grumet about how cooperatives are managing the transition from coal to renewables and balancing clean energy goals with reliability.

FERC upheld the contract termination payment rules for Tri-State Generation and Transmission Association it approved last year, though it modified some of its original order in response to requests for clarification.

The Colorado Public Utilities Commission has proposed rules that would govern how it will review applications from utilities wishing to join the various regional markets being developed in the Western Interconnection.

House members and their state regulator witnesses split over how much an expanded transmission grid could enable a reliable transition to a low-carbon future.

FERC issued an order ending a couple years of litigation over what Tri-State can charge its exiting members, picking a "Balance Sheet Approach" initially proposed by departing member United Power and then modified by commission staff.

FERC found that Tri-State did not demonstrate that United's withdrawal agreement was just and reasonable under the Federal Power Act.
