Microsoft files Nevada tariff to keep data center costs off ratepayers

✓What's documented Sourced to Microsoft's filed Ratepayer Protection Tariff at the Public Utilities Commission of Nevada, Docket 20-08014.

Microsoft filed a proposed Ratepayer Protection Tariff at the Public Utilities Commission of Nevada in May, seeking a framework that splits data center infrastructure costs into a customer-paid share and a system-benefit share that enters the rate base only if it helps the broader grid. It is one of the most detailed utility-rate proposals yet aimed at separating AI buildout costs from the general rate base. The tension it answers is the whole DCND beat in miniature: utilities profit by building infrastructure and rolling it into everyone's rates, so Microsoft is proposing to pay its own way before NV Energy's new data center load lands on residential bills.

• Microsoft filed the proposed tariff in May 2026 at the Public Utilities Commission of Nevada, Docket No. 20-08014.
• Costs split into a Customer Contributed Share paid by the large load and a System Benefit Share eligible for rate-base recovery only if it benefits the broader system.
• A Bring Your Own Power provision lets the customer procure third-party generation; fully developer-funded projects could win approval within 60 days.
• Microsoft has already acquired property for a Nevada data center and says the tariff could offset early costs of the state's Greenlink transmission project.
• The filing aligns with the federal Ratepayer Protection Pledge Microsoft signed in March 2026.
