What is the Regional Portfolio Model (RPM)?
In its Northwest Power Plans, the Council is responsible for developing a resource strategy based on independent analysis of the region’s long-term energy needs and the costs and availability of a wide variety of energy efficiency and generating resources. In addition to minimizing system costs, the analysis addresses major uncertainties and strategies for mitigating risks.
The Regional Portfolio Model or RPM is an electric integrated resource planning model used by the Council to identify adaptive, least-cost resource strategies for the region. The original version of the model was used in developing the Council’s Fifth and Sixth Northwest Power Plans.
The RPM uses a sophisticated and unique risk analysis methodology, developed by the Council, which involves simulating numerous candidate resource plans across a broad range of possible futures to identify tradeoffs between expected cost and risk.
Council staff discusses the model and presents information on model updates, analysis and functionality at it's System Analysis Advisory Committee meetings. View the agendas and video of past SAAC meetings for more information.

As Part of the Council's Power Planning Process, the public may access a limited version of the RPM Online!

RPM Redevelopment Project (2014-2015 - Project is Now Completed)
Information on the Project:
In 2013, the Council decided to redevelop the RPM in order to take advantage of current software technologies, provide increased accessibility to the model, and to get it ready for use in the Seventh Plan.
The redeveloped RPM software is intended to provide the Council with a model that can analyze different electric resource portfolios during the development of the Seventh Northwest Power Plan. Use of the redeveloped RPM will include strategic risk analysis, including cost and risk tradeoffs of differing resource portfolios across a large number of potential futures. The redeveloped RPM may also be used to test various policy propositions (e.g., identify and evaluate strategies for, and costs of, achieving postulated goals for regional power system greenhouse gas emissions).
