The PUD's Integrated Resource Plan (IRP) provides a long-term strategy regarding future energy resources. It establishes an action plan that ensures enough resources are available, at a reasonable cost, to meet future energy loads.
The PUD has completed the Draft 2015 Update to the 2013 IRP. This 2015 Update covers the planning horizon spanning from 2016 through 2028 and reaffirms the PUD’s commitment to acquire new, cost-effective conservation and energy efficiency as its resource of choice. The Preferred Plan identifies cumulative new, cost-effective conservation and additional energy efficiency of 88 average megawatts over the planning horizon. The new conservation and the existing PUD-owned hydro, contracts for wind, customer-owned generation and Bonneville Power Administration supply contracts delay the need for future power supplies until 2021. Starting in 2021, needs are primarily driven by winter peaking needs; future supply resources consist of a mix of contracted winter capacity products, geothermal, wind and biomass.
