Recently I got an email from NV Energy about the annual Deferred Energy Accounting Adjustment (DEAA) consumer session with the Public Utilities Commission of Nevada (PUCN). They had postponed it because they needed a bigger venue to fit everyone who wanted to speak. I wondered why so many people would turn out. It must be important, I thought. That sent me down a rabbit hole trying to understand NV Energy and why our bills work the way they do. (I moved to Nevada a few years ago, so I'm still new to how things work here.)
Here's what I came up with. Every Nevadan should understand the basic machine. Once you see how the pieces fit, the fights in the news start to make sense. The data centers. The new demand charge. The deferred-energy hearings.
Bear with me. There's a TL;DR at the end. Let me walk through it one step at a time. Each piece sets up the next.
-
Start here: it's a monopoly. We cannot switch.
NV Energy is the only game in town. It serves about 90% of Nevada's electric customers. We can't shop for a cheaper provider like we do for phone or internet. That single fact shapes everything, so hold onto it.
-
Who owns it: Berkshire Hathaway.
NV Energy is owned by Berkshire Hathaway Energy. Yes, Warren Buffett's company. Berkshire likes utilities for a specific reason we'll get to. They're an extremely stable place to park enormous amounts of money.
-
How a monopoly is allowed to make money.
With no competition to set prices, a state regulator sets them instead. The deal works like this. NV Energy recovers what it spends building the system: power plants, transmission lines, substations. Then it earns a profit on top. Right now that's an authorized return of about 9.5% on the equity portion of that investment.
Here's the subtle part. That return isn't a literal blank check. It's an authorized opportunity, and only on investment regulators judge "prudent." But in practice, once the spending is approved, the profit is largely assured.
-
The incentive that creates: build more, earn more.
Follow the logic. If a company earns a percentage return on the things it builds, then the more it builds, the bigger its profit. It even has a name: "capital bias." So the company's incentive is to spend on big infrastructure it owns. Not to help us use less. And not to lean on things it can't own, like a neighbor's rooftop solar.
This is the engine. Keep it in mind, because everything downstream runs on it. -
The referee: the PUCN.
Standing between the monopoly and us is the Public Utilities Commission of Nevada. Three commissioners approve rates and decide which costs are fair to pass to customers. Here's the key detail. They're appointed by the Governor, not elected. So they're somewhat insulated from politics. But they are not immune to it. That matters at the end.
-
Our advocate in the room: the BCP.
We don't get to argue rate cases ourselves. But the Bureau of Consumer Protection, in the Attorney General's office, is the taxpayer-funded lawyer that represents regular ratepayers like us when NV Energy asks for more. Just remember they exist.
-
Now, how our actual bill is built. This is the heart of it.
Our bill has two basic parts.
- Base rates. Set every roughly 3 years. They cover infrastructure, operations, and that profit. Relatively stable.
- Fuel and purchased-power costs. This is what NV Energy pays for natural gas and electricity to actually run the system. These get passed straight through to us, dollar for dollar, through a mechanism called the Deferred Energy Accounting Adjustment (DEAA).
The company makes no profit on fuel. But here's the catch. It also takes none of the risk. When gas prices spiked in 2022, customers absorbed the entire increase. We carry 100% of the fuel-price risk. The monopoly carries none.
Profit flows up to the owner. Cost and fuel risk flow down to us, the customers who can't leave. That's the whole machine in one sentence. -
Do the guardrails work? Sometimes. And here's proof it matters.
Between 2012 and 2016, Nevada Power earned roughly $180 million more than its authorized return. That's about $144 per customer, according to its own reports filed with the PUCN. To be fair, that's legal. Rates are set on forecasts, and actual earnings vary. But it was big enough that a casino's expert witness and the consumer advocate pushed back. Customers ultimately got a roughly $110 million rebate.
The lesson: the guardrails only work when someone is watching and pushing.
-
The recurring fight: who pays for the shared grid.
The grid is a shared system, so there's a constant question of who pays for it. Years ago, big casinos like MGM and Wynn used a Nevada law to leave NV Energy and buy power elsewhere. MGM paid an exit fee of about $87 million. Even then, people fought over whether those fees fully covered what the casinos left behind, or whether the rest of us picked up the slack. File that pattern away. It's about to repeat at a much larger scale.
-
The thing that changes everything: data centers.
Now the big customers aren't leaving. They're arriving, and they're enormous. In NV Energy's own 2026 long-range plan (filed with the PUCN), data centers jump from about 5% of NV Energy's total electricity sales today to roughly 64% by 2046. The whole system nearly doubles in size. Serving that means billions in new construction, including the roughly $4.2 billion Greenlink transmission project.
This isn't abstract. It's already happening here. Take Switch, the Las Vegas data-center company. In June 2026, Clark County approved yet another Switch expansion, even as a data-center backlash spreads across the state. Switch's Las Vegas core campus is heading toward about 495 megawatts. Its Reno campus is slated for up to 650. This year alone it bought 316 more acres in North Las Vegas for over $180 million. And it's just one operator. NV Energy estimates that 12 data-center projects in Nevada would need about 5,900 megawatts. That's roughly 2.8 times the capacity of Hoover Dam.
The pushback is real, too. Reno has already adopted a moratorium on new data centers. Henderson is set to vote on its own pause on July 21, 2026, which would make it the first city in Southern Nevada to do so.
-
Connect it back to step 4.
Remember "build more, earn more"? A buildout this big is, from the monopoly's point of view, an enormous opportunity to grow the very thing it earns a return on. So the question for the rest of us is simple. Do the data centers pay for the infrastructure built to serve them? Or does it get spread onto everyone's bills?
-
Here's the twist, and it actually matters.
To its credit, NV Energy's own 2026 plan flatly says data centers "must be responsible for paying their own way to avoid creating upward pressure on existing customer rates." Sounds great, right? Here's the catch. That's a promise in a plan that doesn't itself change rates. The how-much and the enforced-how are still being decided. A promise isn't a rule yet.
The tell that it's unsettled: Microsoft filed its own "ratepayer protection" tariff in 2026, basically asking to be walled off from these costs. When a trillion-dollar company races to define who pays, it's because the answer isn't nailed down.
-
Why we can't just "vote with our wallet."
Remember step 1. We can't switch. In 2018 there was a ballot measure, Question 3, to break up the monopoly and allow competition. It lost, after NV Energy spent about $63 million to defeat it. So the exit door is closed. The only real check left is the regulator, the PUCN.
-
Which is why the boring-sounding hearings actually matter.
This summer the PUCN scheduled a consumer session on the annual deferred-energy (fuel) filing. So many people wanted to speak that they postponed it to find a bigger venue. That's the moment regular people actually get a microphone in front of the people who set the rules.
