Committee reviews H.727 edits to tightly limit PUC role on data center siting, call for new large-load contracts

Summary
The House Energy committee reviewed Department of Public Service edits to H.727 proposing a new "large load service equity contract" for data centers above 20 MW to allocate costs to the facility and keep rate regulation and generation siting with the PUC while leaving land-use siting to Act 250; members raised questions about decommissioning, potential siting gaps and public participation.
The House Energy and Digital Infrastructure committee on Feb. 24 received a detailed walkthrough of proposed edits to H.727 from the Department of Public Service that would create a new contract category for large data centers and clarify which review bodies decide rate and siting issues.
"The primary intent of our edits are really to ensure that rate regulation and electric generation siting remain with the PUC, and under their jurisdiction, while land use siting remains under the jurisdiction of the land use review board," said TJ Poor, director of regulated utility planning at the Department of Public Service. Poor led the committee through red-line changes he said would protect ratepayers while acknowledging potential benefits if large electric loads locate in Vermont.
Why it matters: The edits aim to draw a clearer line between the Public Utility Commission's authority over rates, tariffs and generation-related impacts, and Act 250/land use review board authority over aesthetics, natural resources and community impacts. Committee members warned the split could create a jurisdictional gap for projects that do not meet Act 250 thresholds.
Key provisions and debate
- New contract type: DPS proposed a "large load service equity contract" that utilities would propose and the PUC would approve. Poor said the draft would require any data center over 20 megawatts to enter this contract, which would allocate the costs the facility imposes on the distribution and transmission system so other ratepayers are not left paying for upgrades.
- Generation and export to the grid: Poor clarified that Section 248-style generation siting would be implicated if a data center's on-site generation can export to the grid. "If a data center were to come to Vermont and have a generator that at any point can export to the grid, then... 2 48 is implicated," he said.
- Cost allocation and embedded costs: The proposed contract language requires the data center to contribute toward embedded system costs (for example, poles and wires ratepayers previously financed) and to cover incremental capacity or energy costs caused by the new load. DPS removed the adverb "solely" from one provision to broaden the types of costs that the contract can address.
- Contract length and stranded-cost protections: The DPS edits removed a fixed 10-year minimum duration for contracts and instead rely on stranded-cost provisions and PUC review to ensure facilities or associated infrastructure do not leave unpaid costs for ratepayers. Committee members pressed for clarity on decommissioning and how building/site cleanup costs would be captured.
- Siting, Act 250 and potential gaps: DPS removed PUC requirements that duplicated Act 250 criteria (aesthetics, natural environment, historic sites) and said those matters were better addressed in land-use review. Several committee members raised concerns about a possible gap for projects that fall below Act 250 triggers (for example, projects under 10 acres) and asked staff to revisit whether additional protections are needed.
- Efficiency and demand-side management: The draft requires contracts to include demand-side management measures and load flexibility. Committee members debated whether such measures should be implemented through Efficiency Vermont, other utility efficiency programs, or contract-specific provisions.
- Reporting and finance provisions: DPS removed an earlier proposal for a new financing structure. Instead, it would fold data-center-related reporting into the department's annual energy report and require the facility to report on shared infrastructure built to serve it.
Quotes and committee tone
Poor said the edits attempt to strike a balance: "We're trying to strike that balance here... to ensure protections for ratepayers in view of a tariff for a large load customer, while encouraging load that could be beneficial for all ratepayers and for Vermont." Committee members repeatedly asked for tighter language on decommissioning, public participation in the PUC review of proposed tariffs and whether Act 250 alone will protect communities.
Next steps
No votes were taken. The committee removed a planned Thursday votes item and set aside time during its next meeting to continue questions about H.727 and DPS's suggested edits.
The session closed with the committee scheduling follow-up time to resolve lingering questions on jurisdictional gaps, decommissioning protections and the public process for commission review.
