Integrated Resource Planning

The Energy Planning and Management Program requires Western customers to periodically submit Integrated Resource Plans (IRP) or an approved alternative - Minimum Investment Report, Energy Efficiency and Renewable Energy Report or Small Customer Plan. The IRP must evaluate the full range of alternatives to provide adequate and reliable service to a customer’s electric consumers at the customer’s or member’s lowest system cost. 

Following a public process that began Aug. 21, 2007, Western recently adopted three revisions to its IRP rules. The changes are:

  • Eliminating the requirement that members of a member-based association (MBA) unanimously approve the MBA's IRP
  • Encouraging customers to cooperate on preparing regional IRPs
  • Making customers' current IRPs more accessible to the public by placing them on Western's or the customer's Web site

  Energy Services has developed an online training program for submitting IRPs.  Please take a moment to visit the new pages and let us know if you find them helpful, or make suggestions to improve the training program. Below are more resources to help customers effectively plan to meet their consumers' needs:
