Do you know who sets your electric rate? It's not your utility. It's the Public Service Commission — three people, appointed by the governor, who decide what every utility in Wisconsin can charge you. They're the most powerful government body most people have never heard of.

Here's how it works. Your utility is a regulated monopoly. You can't buy electricity from anyone else. In exchange, they can't raise prices without the PSC's approval. When they want a rate increase, they file a case. The PSC reviews it, holds public hearings, and decides.

Right now, that process matters more than ever. Wisconsin utilities have filed for billions of dollars in new rate increases — driven partly by data centers that could expand electricity demand by forty percent in parts of the state. The PSC is deciding who pays for that: the tech companies, or you.

The Citizens Utility Board — cubwi.org — tracks every rate case and advocates for residential customers. If your electric bill is going up, they're worth knowing about.

The Public Service Commission (PSC) is a three-member body appointed by the governor and confirmed by the state Senate. They regulate all investor-owned utilities in Wisconsin. When a utility wants to raise rates, it files an application, and the PSC reviews it through a formal process including staff analysis, testimony, and public hearings before the commissioners decide. (PSC: How Rates Are Changed)

Rates have been rising significantly. The PSC approved $2.2 billion in rate increases (out of $3.1 billion requested) from 2021-2026. Wisconsin now has the second-highest residential electricity rates and third-highest industrial rates in the Midwest. (WisPolitics)

The latest filing: We Energies and Wisconsin Public Service filed for $500 million in new increases on April 2, 2026, for 2027-2028. We Energies customers could see roughly $13/month increases in 2027 and $9 in 2028. (WBAY)

Data centers are a major driver. Planned facilities in Mount Pleasant (Microsoft) and Port Washington could expand electricity demand by 40% in parts of southeastern Wisconsin between 2026-2030. The Port Washington facility alone would need 1.3 GW — enough to power roughly 800,000 homes. We Energies has filed $5.5 billion in new projects to support data center demand. The PSC held public hearings on February 10, 2026 about a proposed rate structure for very large customers. Microsoft said it would "pay its own way." Consumer advocates are pushing for data centers to cover 100% of infrastructure costs. (Wisconsin Watch; Racine County Eye)

What drives rate increases: Roughly half of recent electric rate hikes are linked to new generation projects (solar, battery storage, natural gas plants). Other drivers include vegetation management, inflation, transmission costs, and supply chain cost overruns. (WPR; CUB)

How utilities make money: Fuel costs are a pass-through — utilities don't profit from them. But they earn authorized returns on capital investments (new plants, transmission lines). This creates an incentive to build new infrastructure. The current authorized return on equity is roughly 9.8-10%. CUB has pushed to reduce it to 9.3%. (Alliant Energy)

Citizens Utility Board of Wisconsin (CUB): An independent nonprofit that advocates for residential and small business utility customers. CUB tracks every rate case, provides testimony, and publishes analysis. Visit cubwi.org.

You can participate. Customers can comment on the PSC's website, attend public hearings on rate cases, or join CUB. (PSC Public Participation)
