The PUCN has final authority; a decision is unlikely before year-end 2026. Until then, every pending Nevada interconnection sits in a regulatory holding pattern
Decision Focus
NV Energy filed its Integrated Resource Plan with the Public Utilities Commission of Nevada in May, projecting data center load growth from 5% of statewide electricity sales today to 64% by 2046. The utility has already received interconnection requests from 39 prospective data center customers totaling approximately 16,530 MW. To meet that demand, it is requesting $3.2 billion in transmission and substation upgrades across 68 substations, 23 new power purchase agreements, and a near-doubling of systemwide capacity from roughly 10 GW to more than 20 GW by 2050. The operational signal for Global Heads of Data Center Energy: Nevada is structurally repricing its grid access terms, and the cost-allocation model being proposed will bind large customers to long-term commitments in ways that alter the commercial calculus for new Nevada facilities.
90-Second Brief
Today, nV Energy’s preferred “Obsidian Plan” seeks PUCN approval for 4,370 MW of new solar PPAs, 5,405 MW of battery energy storage, 180 MW of geothermal, and more than 1,200 MW of gas turbine capacity at Fort Churchill Generating Station, all targeted for activation by 2031. The utility is simultaneously proposing Rule 9-style customer agreements that require large energy users to fund or support the infrastructure their load demands, explicitly to prevent cost shifting onto existing ratepayers. The PUCN has final authority; a decision is unlikely before year-end 2026. Until then, every pending Nevada interconnection sits in a regulatory holding pattern.
What Is Really Happening?
The scale of the Obsidian Plan reveals something structural, not incidental. In NV Energy’s 2024 IRP, the utility requested three PPAs covering roughly 1,000 MW of solar and 1,000 MW of storage. The current filing requests 23 PPAs and nearly five times the storage capacity. That step-change reflects the concentration of inbound demand: 11,710 MW of the 16,530 MW in signed or pending agreements is concentrated in Northern Nevada alone, creating a geographically asymmetric load problem that standard grid planning cycles were not designed to absorb.
The gas turbine additions are particularly telling. NV Energy is requesting over 1,200 MW of aeroderivative and conventional gas turbines at Fort Churchill—phased across 2030 and 2031—alongside its renewable buildout. This is a reliability hedge, not a carbon strategy. It signals that the utility is not willing to bet Northern Nevada grid stability entirely on intermittent generation and storage at this scale and speed. For operators building 24/7 carbon-free energy commitments into their board reporting, that gas capacity backstop complicates Scope 2 accounting for Nevada-based load under hourly matching frameworks.
The cost-allocation proposal is the regulatory innovation to watch most closely. NV Energy is asking the PUCN to require large customers to make long-term service commitments and directly fund infrastructure upgrades—a departure from the traditional utility model in which infrastructure costs are socialized across the ratepayer base. If approved, this functions as an effective precondition for large-scale Nevada interconnection: operators who want capacity will need to underwrite it.
Why It Matters for Global Heads of Data Center Energy
Three operational exposures emerge from this filing.
First, interconnection timing. The PUCN approval process will not conclude until at least late 2026, and the construction timelines embedded in the Obsidian Plan run to 2031. Operators in the Nevada interconnection queue—particularly those with Northern Nevada exposure—are looking at multi-year infrastructure build sequences before committed capacity materializes. That timeline must be synchronized with data center construction schedules now, not after approval.
Second, commercial structure. The proposed large-customer agreements represent a structural shift in how Nevada will price new grid access. If the PUCN approves the cost-allocation framework, entering the Nevada market will require long-term load commitments and infrastructure co-funding, not simply a utility service agreement. That changes the capital structure of Nevada projects and the risk profile of stranded capacity if demand forecasts shift.
Third, the clean energy stack. A grid that doubles in size with a meaningful gas turbine component—even as a reliability backstop—creates basis risk for operators trying to match load with clean generation on an hourly basis. The 4,370 MW solar and 5,405 MW BESS additions are substantial, but their ability to support 24/7 CFE claims depends on dispatch profiles, curtailment rates, and storage duration specifications that are not yet determined through the IRP process.
Forward View
If the PUCN approves the Obsidian Plan largely as filed, Nevada becomes one of the most aggressively capacity-expanded utility territories in the country, with a clear preference for customers who anchor their interconnection with long-term commitments and infrastructure co-investment. Operators who engage early in that framework gain queue position and contractual certainty; those who wait for final PUCN terms may find the most favorable agreement structures already allocated.
If the PUCN modifies or delays approval—particularly on the cost-allocation mechanism—the entire supply build timeline slips, and the gap between inbound demand requests and available capacity widens further. A 16,530 MW request pipeline against a 10 GW current capacity base has no slack. Any regulatory friction translates directly into stranded construction investment for operators who broke ground on Nevada facilities ahead of utility confirmation.
The geothermal component, while modest at 180 MW, is worth tracking as a signal of Nevada’s longer-term resource mix. Geothermal carries a high capacity factor and is non-intermittent—attributes that matter disproportionately for 24/7 CFE compliance. If the PUCN approves and geothermal development scales beyond this IRP cycle, it could meaningfully improve the clean energy quality of Nevada supply.
What Is Still Uncertain
The IRP is a proposal. The PUCN has not approved any element of the Obsidian Plan, and the review timeline extends through at least late 2026. Several operational unknowns remain unresolved: the specific terms and enforceability of the large-customer cost-allocation agreements; the dispatch and duration specifications for the 5,405 MW BESS tranche; whether the executed Rule 9 agreements translate into active interconnection applications or remain conditional; and whether Northern Nevada transmission constraints can be resolved within the $3.2 billion upgrade envelope or require additional capital. None of these are answerable from the IRP filing alone.
One Question for Your Team
If the PUCN approves NV Energy’s large-customer cost-allocation framework, does your Nevada project underwriting model account for the capital and commitment structure that framework would require—and if not, at what point does Nevada become less competitive than alternative markets where that obligation does not yet exist?
