The Idaho-WIEB State Energy Planning (SEP) project is a two year, multi-state, collaborative effort that began in early 2015 and is funded by the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy. The state of Idaho is leading the project effort with support from the original collaborating states: California, Colorado, Montana, Nevada, Oregon, Washington and Utah. All Western states are invited to participate in the project.
The goals of the project are to:
• foster regional and state energy planning in the West;
• identify opportunities for multi-state or region-wide collaborations to address emerging energy issues; and
• develop a roadmap that identifies options for policy makers to advance solutions to selected challenges presented by the emerging issues.
At the beginning of this project we reported in Prioritizing Regional Electric System Challenges for Western States that the Western electric power system is in the midst of the biggest change in at least the past 30 years. This transformation is driven by changes in supply and demand side technologies, federal environmental policies, and state renewable, efficiency and greenhouse gas policies.
Through a stakeholder process four issues were identified on which to focus the work of this project:
1. A Low Carbon Future and Managing Carbon Risk;
2. Maintaining Reliability with the Integration of Distributed Energy Resources;
3. Integration of Variable Energy Resources; and
4. Coal Unit Retirements and Reliability.
The project culminated in a Roadmap for Policy Makers: Options for Addressing Emerging Energy Issues in the West. This is a high level document with an emphasis on options policy makers could take to address the challenges explored in the technical briefs. Final project documents include:
