Integrated System Plan

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 by the end of the year. 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.
