Like many of our readers, I received a June 30 email from NV Energy outlining its January 2027 implementation of a new daily demand charge, which is calculated based on the 15-minute daily period when your usage peaks. It included an estimate for what I would have paid in May under that structure—a $4 decrease for my one-bedroom apartment.
The company tells the Weekly the new charge is “not a rate increase,” but a “restructuring of how electric bills are calculated.” Other components of customers’ bills—like the basic service charge—will decrease to offset the new line item, a spokesperson wrote. Reflective of my own estimate, the utility maintains that “most residential customers” should see little change or even a slight decrease in their average bill, “depending on their individual usage patterns.”
However, ratepayers with home solar panels may not share the potential decrease, as NV Energy has also estimated that solar customers could see bills rise from $12 to $20 per month under the daily demand charge. That’s largely because solar customers normally earn net-metering credits for excess solar they collect and send back to the grid. But those can’t be applied against the daily demand charge, so if a solar customer’s single highest-use moment happens when their panels aren’t producing, their highest 15 minutes of use count fully even if their panels are otherwise generating a surplus.
“The new structure also helps address inequities in the current rate design, where rooftop solar customers pay less toward the cost of maintaining the grid than non-solar customers, even though all customers rely on that infrastructure,” NV Energy explains on its website.
This apparent disparity has drawn legal opposition from both Nevada Attorney General Aaron Ford and renewable energy advocacy groups like Vote Solar and Earthjustice. Ford’s Bureau of Consumer Protection has mounted a lawsuit challenging the change, while Vote Solar and Earthjustice have filed their own. Both were dismissed within 48 hours of each other in late May but are separately appealing to the Nevada Supreme Court.
It’s an important distinction in a state that ranks seventh nationally for total installed solar capacity, according to the Solar Energy Industries Association. Ford’s office and Vote Solar estimate that roughly 10% of Southern Nevada homeowners use rooftop solar systems, meaning the fix could create problems for a sizable number of customers.
Brad Heusinkveld, Vote Solar’s Interior West regulatory director, argues the charge is not just legally dubious but also poor policy design.
“It’s hard for customers to adopt, understand and manage,” he says. “While it may not increase rates on average for the customers, people are going to see a lot more variability month to month depending on their usage. That’s especially difficult for people on fixed incomes or low-income families.”
He also says it could take away incentives from adopting solar panels.
“The demand charge puts those costs in such a bucket that those benefits are hard to grasp for customers. So, if they’re not compensated correctly, fewer people will invest in those, and the grid will have less access to customer-side resources that, in aggregate, can lower costs for everyone,” he says.
Speaking in a media briefing on May 27, Ford said he believes his own case against the daily demand charge is “far from over.”
“It undermines Nevada’s clean energy future, and it violates a state law that has been on the books since 2013,” Ford said. “Nevada law explicitly bans time-based rate structures. This charge is exactly that.”
Julia Hubbard, Nevada director for Solar United Neighbors—another nonprofit not engaged in the lawsuit—argues that the new charge doesn’t even target the problem NV Energy says it’s solving. She says the mismatch is compounded after dark, when panels aren’t producing at all.
“One of our critiques of this charge is it doesn’t actually coincide with when the grid is most strained, which again is that 5 p.m. to 9 p.m. period,” Hubbard says. “That’s when everybody is coming home and making dinner.”
Heusinkveld and Hubbard both see a bigger opportunity beyond this fight to fairly compensate customer-owned solar and battery usage to lower system-wide costs.
“It’s a moment where we can envision a more democratic energy future, where customers have more control over their energy and can use their voice to make that possible,” Hubbard says.
