OPPD's Integrated System Plan (ISP) is a vital step in our continual planning process to guide us as we make long-term system plans.
Like most utilities, OPPD engages in ongoing system planning, with an intentional focus on publishing an update to our resource and system strategies every five years. The update also meets a regulatory requirement set by Western Area Power Administration (WAPA) as part of a long-term contract to receive hydroelectric power.
In early 2026, OPPD will begin its ISP engagement process, with a final report submitted to WAPA in October 2026.This planning process is important to ensure we are ready to support growth and maintain reliability for our customer-owners and the ISP guides how we optimize our energy portfolio and measure potential additions over time.
The last time we submitted an Integrated Resource Plan to WAPA was in 2021. The planning process will differ slightly this time because OPPD will take a broader look at overall system needs, rather than just resource needs. This expanded view will allow OPPD to evaluate generation options in conjunction with related grid infrastructure and customer solutions, including the cost of potential grid buildout and modernizations and other factors in evaluating long-term options.
Long-term, taking an integrated systems approach to planning may uncover grid or customer solutions that can help with generation needs and vice versa which will help optimize the overall planning process.
The study also looks at how our resources actually are being used. In addition to traditional models that forecast the economic dispatch of generating units on the basis of cost only, a system plan will consider the current and future generation required for grid support and system reliability. This creates a modeled portfolio that performs much closer to real-world operations and captures the full range of costs and values.

Stakeholder feedback is an important aspect of our integrated system plan. In fact, WAPA requires ample opportunity for full pubic participation when preparing and developing the plan. Fill out the survey below to receive information on upcoming outreach activities, beginning in 2026.

Resource planning is an ongoing process at OPPD. However, every five years OPPD prepares, files, and publishes an Integrated Resource Plan (IRP) with the Western Area Power Administration (WAPA) as a result of OPPD’s long-term contract to receive hydroelectric power from WAPA. An IRP is a legal requirement that outlines a utility's generation changes to meet customer demands over time.
OPPD's Integrated Systems Planning (ISP) process will help drive the IRP, which will be complete in October 2026. If you are interested in participating in this process, please fill out the survey below to receive detailed information as it becomes available.
