HB503 amends Virginia’s electric utility ratemaking statute, § 56-585.1, to add a specific rule for costs tied to serving large data center customers. The bill provides that costs substantially related to providing electric service to data center customers, and costs that would not have been incurred but for those customers’ demand, may not be included in rates charged to other customers unless the rates are designed to recover those costs solely from data center customers. The bill defines a data center customer as a data center with peak demand of 100 megawatts or greater.
The bill also retains and reorganizes the broader framework governing utility cost recovery, earnings reviews, rate adjustment clauses, and Commission oversight for investor-owned electric utilities. It continues to address recovery of costs for generation, transmission, distribution, energy efficiency, renewable energy, grid transformation, undergrounding, nuclear and coal-related investments, and other utility projects, while preserving the State Corporation Commission’s authority to review prudence, set rates, and order customer credits or rate reductions in certain circumstances. It also adds a reporting requirement on reliability impacts of generation additions and retirements.
In practical terms, the bill would change how utility costs associated with very large data center loads are allocated, likely shifting those costs away from the general body of ratepayers and toward the data center customers themselves. It would affect investor-owned incumbent electric utilities, the State Corporation Commission, and large data center operators, while leaving the existing ratemaking structure in place for other utility costs and customer classes.
The general sentiment reflected in the bill’s handling is cautious rather than strongly polarized: it was introduced and referred to Labor and Commerce, then continued to the next session by voice vote, suggesting the committee was not ready to advance it immediately. No recorded floor votes or transcripts are provided, so there is no direct evidence of debate in the materials, but the bill’s subject matter indicates an effort to address concerns about cost shifting from large electricity users to ordinary customers.
The main point of contention is likely whether utilities should be allowed to recover data-center-driven costs from the broader rate base or whether those costs should be isolated and charged only to the large customers creating them. Related concerns may include the impact on economic development, utility planning, and rate fairness for residential and small business customers, as well as how the rule would interact with existing Commission authority over utility cost recovery and special rate clauses.
HB503 would amend § 56-585.1 of the Code of Virginia to create an explicit limitation on utility rate recovery for costs substantially related to serving data center customers with peak demand of 100 megawatts or more. Under the bill, such costs could not be included in general rates unless the Commission approves rates designed to recover those costs solely from data center customers. The measure would therefore affect how investor-owned utilities allocate fuel, generation, transmission, and related service costs, and it would likely reduce the risk that those costs are spread across other customer classes.
The available legislative history suggests a neutral-to-cautious reception. The bill was referred to committee and then continued to the next session by voice vote, which typically indicates that members were not prepared to advance it at that time but also did not reject it outright. Because there are no committee transcripts or recorded votes in the materials, there is no direct evidence of detailed support or opposition, but the bill appears to address a policy concern that is likely to draw interest from both consumer advocates and utility/data center stakeholders.
The central contention is cost allocation: whether the expenses created by very large data center loads should be borne by those customers alone or shared across all ratepayers. Supporters of the bill would likely argue that ordinary customers should not subsidize infrastructure and operating costs driven by data center growth, while opponents may argue that strict cost isolation could affect utility planning, pricing flexibility, and Virginia’s ability to attract large-scale digital infrastructure investment. Additional tension may arise over how broadly the Commission interprets costs that are “substantially related” to data center service and what evidence is required to show a cost would not have been incurred otherwise.
