Nevada regulators weigh data center power deals in North Las Vegas as redactions limit public view of who pays

What happened

Data center developers are challenging some of the safeguards NV Energy has proposed to keep the cost of serving their projects from landing on other customers, the Las Vegas Review-Journal reported. The fight is unfolding before the Public Utilities Commission of Nevada as it considers agreements with future data center customers, including projects under development in North Las Vegas.

The Review-Journal found that confidentiality claims and redactions keep the public from seeing the project-specific details needed to judge whether those safeguards are strong enough. The newspaper reviewed proposed agreements, utility testimony and power plans, and filed multiple public records requests with the PUC.

Why data centers are different

A new scale of demand

Many developers now seeking service from NV Energy want 300 to 500 megawatts of electricity, according to Shawn Elicegui, the utility's senior vice president of regulatory and resource planning. He said that is six to 10 times the roughly 50 megawatts a major casino or mine might use. "There's really nothing comparable to data center load," Elicegui told the Review-Journal.

Paying for committed power

Households and small businesses mostly pay for the electricity they use. Data centers usually commit ahead of time to how much power they expect to need and can be required to make minimum payments on those commitments even if they use less. If a project falls short, the utility could be left with costs it expected that customer to cover, and some could shift to other ratepayers, the Review-Journal reported.

The North Las Vegas cases

Prologis and the 70 percent question

The minimum-billing dispute is part of a pending PUC case over proposed large-load service agreements between NV Energy and industrial real estate company Prologis for at least one data center project in North Las Vegas. Prologis argues a 70 percent minimum better fits how data centers operate, saying their use does not consistently reach 90 percent of capacity and can change as tenants move in.

NV Energy spokesperson Justin Hopkins said the utility has not done a side-by-side analysis of minimums at 70 percent, 90 percent and 100 percent while holding other terms constant. He said the percentage should not be viewed alone because other rates and contract terms also matter.

Novva and Proton filings largely hidden

Less is known about at least two other North Las Vegas data centers, from Novva and Proton, both of which declined to comment through attorneys. The PUC told the Review-Journal it had no public, nonconfidential versions of the projects' Rule 9 agreements, which govern how grid connection equipment is built and paid for.

The Novva agreement lists a 48-month ramp-up period, but the schedule showing how fast its demand would grow is redacted. The PUC also withheld records on cost responsibility and potential cost shifting, citing attorney-client privilege, work-product protection and deliberative-process privilege.

What experts and the utility say

Sarah Wang, a senior associate at research organization RMI, said a 70 percent minimum could cover all new costs if the rates and contract terms are adequate, while even a 100 percent minimum might not if they are not. Ari Peskoe, director of the Electricity Law Initiative at Harvard Law School, said, "There's too much confidentiality in public utility commission proceedings."

Elicegui said NV Energy has produced cost calculations showing its minimum charges would cover 100 percent of costs. The attorney general's Bureau of Consumer Protection, which represents utility customers, declined an interview, citing the potential for "future legal action."

Other protections in the agreements

NV Energy's proposed agreements also include a special charge for new generation and transmission, a preliminary charge for long-term energy, financial guarantees and payments for leaving early. Experts told the Review-Journal these cannot simply be added together, because a guarantee backs an obligation and an exit payment can overlap with minimum bills that would have come due.

What to watch next

• The pending PUC case on NV Energy's proposed large-load agreements with Prologis, including Prologis' push for a 70 percent minimum.
• NV Energy's review of Rule 9, required by a 2025 PUC settlement, aimed at keeping data center connection costs off other customers.
• Elicegui said NV Energy is not planning to begin pursuing generation tied to a large-load agreement until both the commission and the customer have signed off on it.
