New Law Targets Energy Costs in Data Center Builds

Data centers consume roughly 1–2% of global electricity, and in the United States alone, that figure is closer to 4%. It's climbing fast as AI workloads, cloud expansion, and streaming demand compound year over year. For years, local governments watched hyperscalers and colocation providers drop massive facilities into their jurisdictions — drawing on the grid, pulling from aquifers, and quietly reshaping utility bills for everyone else in the region. Now, at least one legislature has decided enough is enough.

A new law targeting future data center builds is moving the industry from a posture of voluntary sustainability commitments to one of legal accountability. This shift matters because voluntary pledges have a long track record of bending under commercial pressure — enforceable policy doesn't.

What the Law Actually Does

The legislation focuses on three pressure points that have historically been treated as externalities: local energy price impact, water consumption, and the broader community footprint of large-scale data center development. Rather than applying blanket restrictions on where data centers can be built or how large they can be, the law takes a more surgical approach — requiring developers to directly account for what their facilities will cost the surrounding grid and watershed before breaking ground.

This is a meaningful distinction. Previous regulatory attempts often tried to slow data center growth through zoning or permitting friction. This framework instead asks: what is the actual measurable impact on local infrastructure, and who pays for it?

The answer, under this law, won't default to "ratepayers and municipalities" anymore — at least not without a fight.

Energy Prices: Who's Been Absorbing the Cost

The energy price question is where this law will generate the most friction with the industry.

Large data center operators have long benefited from economic development incentives — tax abatements, discounted utility rates, and in some cases, direct subsidies — on the premise that they bring jobs and tax revenue. The jobs argument has weakened considerably as hyperscale facilities have become increasingly automated. A 100 MW campus might employ 30–50 full-time workers. Meanwhile, the load they place on local transmission infrastructure can trigger upgrade costs that get socialized across all ratepayers in the region.

This isn't hypothetical. Utilities in Virginia — home to the world's largest concentration of data centers — have flagged data center load growth as a primary driver of rate increases for residential customers. Dominion Energy's most recent integrated resource plan projects tens of billions in new generation and transmission investment, much of it attributable to data center demand in Northern Virginia.

When a single industry sector drives grid expansion costs that are distributed across millions of households, that's a policy problem — and this law treats it as one.

The new regulations appear designed to make that cost relationship explicit. Developers may face impact assessments, cost-sharing requirements, or direct contributions to grid infrastructure upgrades tied to their specific load additions. The details will matter enormously here. A well-designed impact fee structure can level the playing field. A poorly designed one becomes a negotiable checkbox that developers game through project phasing or entity structuring.

Water Use: The Quieter Crisis

Energy gets the headlines. Water is the story that's been building beneath the surface.

Most hyperscale data centers use evaporative cooling — a highly effective approach that also consumes millions of gallons of water annually. A single large facility can use anywhere from 1 million to 5 million gallons per day depending on climate, cooling system design, and utilization rates. In arid or water-stressed regions, that's not a footnote — it's a genuine resource conflict with agriculture, municipal supply, and ecological baseflow.

The new law's attention to water use is significant because water regulation for commercial facilities has traditionally been fragmented — handled piecemeal through state water rights law, local permitting, and voluntary disclosure frameworks. Bringing water consumption into the same regulatory conversation as energy impact creates a more coherent accountability structure.

Practically, this could push developers toward liquid cooling architectures — direct-to-chip or immersion cooling systems that dramatically reduce water consumption compared to evaporative approaches. The technology is mature enough to deploy at scale; the barrier has mostly been capital cost and operational familiarity. Regulatory pressure has a way of accelerating technology adoption that economics alone doesn't — data center operators who've already invested in liquid cooling infrastructure may find themselves with a competitive advantage overnight.

How Developers Should Be Thinking About Compliance

The instinct for many operators will be to treat new regulations as a compliance problem — something to hand to legal and permitting teams while the core business continues as planned. That's the wrong frame.

Developers who adapt their site selection, infrastructure design, and utility engagement strategies now will move faster and cheaper than those who treat each new project as a fight with regulators. A few specific adjustments are worth building into standard practice:

Early utility coordination is no longer optional. Understanding how a proposed load will affect the local grid — and coming to that conversation with mitigation proposals rather than waiting for regulators to impose them — builds credibility and often shortens timelines.

Water sourcing transparency will likely become a standard disclosure requirement. Developers should inventory their cooling system water sources, volumes, and discharge practices now, not after regulators ask.

Site selection criteria need to expand. Grid capacity, water stress indices, and regulatory environment should carry equal weight alongside land cost, fiber connectivity, and power pricing. A site that's cheap to build on but expensive to permit and operate isn't actually cheap.

The broader lesson from other regulated infrastructure sectors — utilities, pipelines, transmission — is that the developers who engage constructively with the regulatory process tend to shape it. Those who resist tend to get regulated more harshly.

The Market Implications Are Larger Than They Appear

A single state law might seem like a regional concern. It rarely stays that way.

Virginia's data center regulations, California's water disclosure requirements, and Texas's grid reliability rules have each influenced how developers approach projects nationally — because operators who want to build everywhere need frameworks that travel. When one major market raises the bar, sophisticated operators often standardize to that bar rather than maintaining parallel compliance systems.

This law, depending on how it's implemented and enforced, could effectively set a new baseline for what responsible data center development looks like across the country.

The investment community is watching closely. Infrastructure investors and REITs that hold data center assets are increasingly subject to ESG disclosure requirements of their own — from the SEC's climate disclosure rules to LP-level reporting expectations. A portfolio of data centers with documented energy impact liabilities and undisclosed water risk is a harder story to tell than it was five years ago. Regulatory compliance isn't just an operational consideration anymore; it's a balance sheet consideration.

What Comes Next

The facilities getting built in the next 24–36 months will be the first to navigate this new framework. That's actually a narrow enough window that developers with projects already in the pipeline face real decisions: retool designs to get ahead of requirements or accelerate permitting under existing rules before new standards take effect.

Neither path is obviously right for every situation. What's clear is that the era of data centers being essentially self-regulated on energy and water impact is closing. The utilities, municipalities, and residents who've been quietly absorbing those costs have found political voice, and the regulatory response — whatever form it ultimately takes — reflects a durable shift in how communities evaluate the tradeoff between digital infrastructure investment and local resource stewardship.

Operators who recognize that early, and build it into their development DNA rather than their legal defense budget, will be the ones still growing when the dust settles.
