Wyoming lawmakers are mulling whether to apply a tax on entities that generate electricity, including owners of yet-to-be-built facilities to power data centers, as a way to ease monthly electric bills for average customers and to potentially create a revenue windfall for the state to spend where n eeded. Lander Republican Sen. Cale Case pitched the ideas to the Legislature’s Revenue Committee last week, noting that a range of Wyoming customers — from homeowners and businesses to industries like trona mines — are suffering continual rate hikes. Some industries and municipalities can’t get extra power in a timely fashion, Case added, while many others worry about the sprawl of wind turbines.  “These are all kind of connected, and taxation policy is a tool that we could use to address some of these issues.” Tax burden shift The first of two potential bill drafts, Case suggested, could create a tax paid by utility companies that generate electricity while eliminating or reducing a retail sales tax that their customers already pay. Plus, lawmakers can discriminate. “Taxes on electricity [producers] don’t have to be equal,” Case said, adding that the Legislature could favor nuclear or fossil fuels over wind energy, for example. “It’s a policy tool that will moderate the growth of renewables in Wyoming.

But legal concerns stymied past legislative efforts.  Wyoming exports about 65% of the electricity generated in the state, according to the Legislative Service Office. While it’s tantalizing to tap companies that also serve out-of-state customers for revenue that would stay in Wyoming, there are legal considerations, Cale conceded. The federal Dormant Commerce Clause outlaws “excessive burdens” on interstate trade. Case invited Sterlington Law attorney Robert Kantowitz to opine on the legal minefield. If a tax is narrowly applied to electrical generation in Wyoming, Kantowitz said, it should withstand legal challenges. “Our feeling is that it’s pretty clear it’s not a discriminatory tax,” he said. “Basically, if you come into Wyoming and you produce electricity in Wyoming, you pay a tax on that — the same as if you come into Wyoming and you extract minerals from the state; you pay a severance tax.” An attorney representing the Wyoming Industrial Energy Consumers group — a powerful collection of companies with coal mines and oil and gas refineries — told the legislative panel he believes such a tax scheme might be legal. However, Nikolas Stoffel of the Holland and Hart law firm cautioned against it. Though the intent is to shift a tax burden from customers to their electricity provider, “It’s going to impact their provider’s creditworthiness and ability to attract capital and ability to provide service at the lowest possible cost over the long term,” Stoffel said, adding that those factors will ultimately result in higher rates for customers. Others cautioned against using such a tax scheme to disadvantage certain types of electrical generation, like wind energy. Wind turbines north of Medicine Bow.

The company is developing the massive $5 billion, 3,550-megawatt Chokecherry and Sierra Madre Wind Energy Project in Carbon County. Wyoming already has an electric generation tax, Choquette noted — a $1 per-megawatt-hour charge on wind energy generation that was instituted in 2012. Since then, the tax has contributed more than $66 million in revenue, according to state data.  Wind energy also provides significant sales-and-use and property taxes, Choquette said. Property taxes are based on an annual “assessed valuation,” and the assessment for all electric generation and transmission facilities has risen to $750.2 million in recent years — second only to oil and natural gas facilities in the state. Plus, she noted, the “Big, Beautiful” budget reconciliation bill in 2025 enacted a measure to send tax revenue derived from wind development on federal lands back to the state and county of origin. The federal “revenue sharing” is split 25% to the state and 25% to the county. The federal program is something that Power Company of Wyoming and state lawmakers started lobbying for more than 10 years, Choquette said. “So we’re so pleased that that will now be happening, starting this year. That’s really good news.” ‘Mega’ energy producers, consumers Case proposed the panel consider drafting a second measure regarding taxing the electrical generation for “large load” producers and/or customers, noting that data center developers envision a buildout so large their facilities could demand triple the amount of electricity now consumed in the state.

But a tax on that “large load” and “dedicated customer” power generation could create a huge new revenue stream to be distributed throughout the state, Case says. “It’s totally up to us to decide [where to spend the new revenue],” Case told the panel. “But we need stable funding for local governments around the state. It’s not really fair that [revenue] windfalls accumulate in one area.” Committee members directed staff to draft a pair of bills. The Revenue Committee meets next in August.
