The Oregon Court of Appeals has upheld a decision made by the Public Utility Commission of Oregon (PUC) regarding the recovery of costs associated with energy storage projects. The ruling affects Portland General Electric Company (PGE), which sought to recover expenses for standalone energy storage projects through an automatic cost recovery process. This decision is significant as it clarifies the interpretation of Oregon's renewable energy laws and the limits on how utility companies can recover costs.
The case, titled Portland General Electric Company v. Public Utility Commission of Oregon, was filed under docket number A186771 and was argued on June 30, 2026. The court's ruling, issued on September 16, 2026, was delivered by Judge Jacquot, alongside Judges Egan and Armstrong. The court affirmed the PUC's decision, which had denied PGE's request for automatic cost recovery for its standalone energy storage projects.
Background
Portland General Electric Company (PGE) is one of Oregon's largest electric utility providers. The company provides power to millions of customers and is subject to regulations by the PUC. The dispute arose from PGE's interpretation of the term “associated energy storage” as defined in Oregon law, specifically ORS 469A.120(2)(a). This law allows qualified electric utility companies to recover certain expenses related to renewable energy through an automatic adjustment process, rather than through a general rate case.
PGE argued that expenses for standalone energy storage projects should qualify for this automatic recovery process. However, the PUC rejected this argument, stating that the law does not permit such recovery for standalone energy storage. The PUC maintained that a general rate case is the appropriate mechanism for recovering costs associated with standalone energy storage projects.
The Ruling
The Oregon Court of Appeals ruled in favor of the PUC, affirming its interpretation of ORS 469A.120(2)(a). The court stated, “the term ‘associated’ does not refer to all energy storage investments; rather, cost recovery under ORS 469A.120(2)(a) is available for capital investments in the construction or acquisition of ‘facilities that generate electricity from renewable energy sources’ and the transmission and storage costs associated with those particular facilities.” This ruling clarifies that only costs related to energy storage that is directly connected to renewable energy generation facilities can be automatically recovered.
Judge Jacquot emphasized that allowing PGE's interpretation would render the term “associated” meaningless. The court explained that if all energy storage resources within a power system were to qualify for automatic recovery, it would undermine the legislative intent behind the law. The PUC had previously concluded that the statute intended to cover only storage and transmission more directly connected to renewable energy resources.
Impact
This ruling has significant implications for utility companies in Oregon. It reinforces the PUC's authority in determining how utility costs are recovered and sets a precedent for interpreting the term “associated” in the context of renewable energy projects. The decision indicates that while energy storage is crucial for integrating renewable energy into the grid, not all storage costs will qualify for automatic recovery under current laws.
For PGE, this means that it will have to continue to seek cost recovery for its standalone energy storage projects through the more lengthy and complex general rate case process. This may impact the company's financial planning and its ability to invest in future energy storage projects, as the costs will not be recovered as quickly as they would have under the automatic adjustment process.
What's Next
While the court has affirmed the PUC's decision, PGE may still have the option to appeal the ruling to the Oregon Supreme Court. However, details regarding any potential appeal or related cases were not available in the court filing. The outcome of this case could influence future legislative discussions around energy storage and cost recovery in Oregon.
