Integrated Resource Plan
The RRC develops Integrated Resource Plans for the entire Railbelt grid. These plans detail what energy generation, storage, system control, and transmission assets should be developed over the coming years.
On July 7, 2025, the RRC Board approved Resolution 20250707-05 authorizing the CEO to initiate the IRP Development process.
The IRP is governed by Alaska Statute AS 42.05.780 and Alaska Administrative Code 3 AAC 46 Article 2. The RRC Board adopted Board Procedure BPR603 during the September 29, 2025 Board meeting, the procedure defines the IRP process.
What is an IRP
The RRC's integrated resource plan is a planning study which produces portfolios of generation, transmission, energy storage, and system control assets for various possible future scenarios. The IRP takes a twenty year forecast of various factors like demand growth, fuel prices, and available technologies and performs an economic and technical evaluation to determine the greatest value mix of resources to meet the future system conditions. The outcome of the IRP is a preferred portfolio of assets accompanied by an action plan to implement those assets.
The RRC will produce an IRP every four years and will update the plan every two years.
