Berkshire’s PacifiCorp Asks California For 57% Increase
Berkshire Hathaway’s utility subsidiary PacifiCorp has filed a request with the California Public Utilities Commission (CPUC) seeking a 57% increase in the rates it charges its California customers, according to the filing. The move, confirmed in late 2026, would raise average residential bills significantly for the roughly 1.6 million customers PacifiCorp serves nationwide, with the California share representing a small but regulated portion of that base.
The request comes as utilities across the western United States face rising costs from wildfire mitigation, grid hardening, and higher wholesale power prices. PacifiCorp, which operates as Rocky Mountain Power in Utah, Wyoming, and Idaho and as Pacific Power in Oregon, Washington, and California, has been under pressure to invest in wildfire prevention following a series of devastating blazes linked to its equipment in recent years.
Why A 57% Jump Is Harder To Swallow Than It Looks
Rate cases are rarely simple arithmetic. A 57% request is a headline figure; the approved increase, if any, typically comes in far lower after months of hearings, public comment, and negotiation with the CPUC’s Public Advocates Office. The commission has historically trimmed utility requests, and consumer groups are already signaling opposition.
For PacifiCorp, the ask reflects a multi-year spending plan. Wildfire mitigation alone has driven billions in capital expenditures across its six-state service territory. In California, the company must also account for higher insurance premiums and the cost of maintaining aging infrastructure in high-fire-risk zones. Without a rate increase, the utility argues, those costs would fall on shareholders rather than customers.
But the timing is politically sensitive. California ratepayers have seen electricity bills climb sharply in recent years, and the CPUC has been criticized for approving increases that outpace inflation. A 57% jump—even phased in over multiple years—would be among the largest single-utility requests in recent memory.
Berkshire’s Utility Arm Under The Microscope
PacifiCorp is one of several regulated utilities owned by Berkshire Hathaway Energy, a subsidiary of Warren Buffett’s Berkshire Hathaway. The energy unit has faced headwinds, including litigation costs related to the 2020 Labor Day wildfires in Oregon and California. In 2024, PacifiCorp agreed to pay hundreds of millions in settlements to wildfire victims, and the company has continued to set aside reserves for future claims.
Berkshire Hathaway’s stock ($BRK.B) has historically been viewed as a defensive holding, but the utility segment’s regulatory risk has become a more visible factor. The rate case will test whether the CPUC allows PacifiCorp to recover wildfire-related costs through customer bills, a mechanism known as securitization or cost recovery that other California utilities have used.
Berkshire’s broader portfolio—including insurance, freight rail, and manufacturing—dominates its earnings, so a single rate case is unlikely to move the stock. But it adds to the narrative that regulated utilities are becoming riskier bets as climate-related costs mount.
What The CPUC’s Decision Could Signal For Other Utilities
California’s regulatory decisions often set a precedent. If the CPUC grants a substantial portion of PacifiCorp’s request, other utilities in the state may point to it when seeking their own increases. If it rejects the request outright, investor-owned utilities could face pressure to absorb more costs, potentially delaying wildfire mitigation work.
The CPUC has not yet scheduled a procedural schedule for the rate case. Typically, such cases take 12 to 18 months to resolve, with interim rate increases possible. The Public Advocates Office and consumer groups are expected to intervene.
For Berkshire Hathaway investors, the key figure to watch is the final approved revenue requirement, not the requested 57%. A smaller increase would still allow PacifiCorp to recover some costs, but it would shift more of the burden to shareholders. A larger increase would bolster the utility’s cash flow but invite political backlash.
What To Watch: The CPUC’s Final Number And The 2027 Rate Case Calendar
The next concrete milestone is the CPUC’s assignment of a commissioner and administrative law judge to the case, expected in the coming weeks. From there, a schedule of hearings and briefs will follow, with a final decision unlikely before late 2027. Investors should watch for any interim rate relief and the scope of wildfire cost recovery approved.
The 57% figure is a starting bid, not an outcome. If the CPUC approves anything close to that, it would mark a significant shift in how California allocates climate risk—and a warning for ratepayers across the West. If it is rejected, Berkshire’s utility arm will have to absorb more of the cost, with implications for future rate requests and wildfire liability.
