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’s 2013 IRP covers the planning horizon spanning from 2014 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 109 average megawatts over the planning horizon – enough energy to serve nearly 90,000 homes. With the PUD’s owned hydro, contracts for wind, customer-owned generation and Bonneville Power Administration supply contracts, future power supplies are not needed until 2024. Future power resources consist of a mix of small hydro, landfill gas, geothermal, wind and biomass.
