Virginia lawmakers from both parties are pressing state leaders to pause approval of new data centers until officials can fully assess their impacts on the power grid, groundwater and other public resources.
Lawmakers call for immediate review
Republican State Sen. Glen Sturtevant this week urged Gov. Abigail Spanberger to impose an immediate moratorium on all new data center development, saying the issue has moved beyond regulation to a question of whether the commonwealth can accommodate further growth.
“The question is no longer simply how to regulate more data centers. It is whether Virginia can accommodate data center development at all,”
Democratic Senate President Pro Tempore Louise Lucas followed with public support for a moratorium, saying the status quo is unsustainable and that the proposal merits serious consideration.
What prompted the push
The renewed scrutiny comes after a July incident when a high-voltage transmission line in Ashburn went offline and several data centers switched to backup power. That abrupt change in demand reportedly produced voltage fluctuations that were detected across a broad swath of the Eastern Interconnection — from Chicago to Boston to Miami — and caused lights to flicker in millions of homes.
Energy experts told local media the event had the potential to trigger far more severe outages under different conditions. Lawmakers cited that incident and growing resource pressures as key reasons to pause new approvals and study the cumulative effects of continued data center growth.
Bipartisan pressure and broader concerns
The call for a moratorium is not confined to a single party. Alongside Sturtevant and Lucas, Republican Sen. Richard Stuart and Democratic Sen. Russet Perry co-signed a letter to the governor requesting a special legislative session focused on the state’s groundwater supply — an issue closely tied to data centers because large facilities commonly rely on significant water for cooling.
Advocates for a pause say the proposals are about protecting public services and infrastructure, not an attack on economic development. Opponents — including some industry representatives and localities that benefit from data center investment — have in the past argued that these facilities bring jobs and tax revenue. The current push, however, centers on whether the state can sustainably provide electricity and water at the scale operators require.
Immediate questions for state leaders
- Can Virginia’s electrical grid reliably absorb additional, concentrated demand from more data centers?
- Are current groundwater resources sufficient to serve large cooling operations without harming public supplies?
- What regulatory or infrastructure changes would be necessary to permit safe, responsible growth?
Those are among the questions senators want the governor and the General Assembly to address before new projects move forward.
Local impact and statewide implications
Northern Virginia has become a global hub for data center development, and the state’s policy choices will affect utilities, local taxation, land use and environmental planning across counties. A pause in approvals could give regulators and utilities time to analyze cumulative impacts, coordinate upgrades, and consider stricter siting or resource-use rules.
For residents, the debate is increasingly about reliability and long-term access to water and power. The July transmission event — which prompted some centers to run on backup generators — illustrated how sharply the grid can be tested when large facilities change their power supply behavior.
Who has weighed in so far
So far, public statements and letters have come from lawmakers in the Senate urging action. The letter from Senators Stuart and Perry specifically requested the governor convene a special session aimed at groundwater concerns. State executives, utility companies and the data center industry have yet to issue a single unified response in the reporting so far.
| Senator | Party | Position |
|---|---|---|
| Glen Sturtevant | Republican | Called for immediate moratorium |
| Louise Lucas | Democrat | Supported considering a statewide moratorium |
| Richard Stuart | Republican | Signed letter urging special session on groundwater |
| Russet Perry | Democrat | Signed letter urging special session on groundwater |
The signatories represent a cross-section of the Senate, underscoring the bipartisan nature of current concern.
Next steps
The senators are urging Gov. Spanberger to act — either by issuing a moratorium herself or calling lawmakers into a special session to evaluate water availability, grid resilience and any regulatory changes needed. If the governor calls a session or agrees to a temporary halt, the legislature and executive branch would face choices about timelines, criteria for resuming approvals and what technical studies or infrastructure investments are required.
As Virginia weighs its next moves, the stakes are practical: ensuring reliable electricity, protecting groundwater for public use, and balancing economic development with the state’s capacity to sustain rapid, concentrated growth in the data center sector.
