HB1219, titled the Maryland Co-Location Energy Innovation and Reliability Act, would require the Public Service Commission (PSC) to adopt regulations governing the construction of a generating station that is co-located with a data center and is not interconnected with the electric transmission or distribution system. The bill is aimed at a specific class of behind-the-meter or otherwise isolated energy facilities paired with data centers, and it directs the PSC to create rules for how those projects are reviewed and operated.
The bill specifies that the regulations must treat such a generating station as an independent resource not subject to state laws and regulations that apply to retail electric customers or electricity suppliers. It also directs the PSC to clarify that state-mandated distribution fees and renewable energy portfolio standard obligations do not apply to the station or the energy it produces, while also requiring backup power for reliability, cybersecurity safeguards, and protections to ensure the facility does not interact with the grid. Applicants for a certificate of public convenience and necessity would need to show that the project will remain unconnected to the grid, comply with applicable state and federal law, and contribute to Maryland’s energy goals. Owners or operators would also have to file annual reports on energy sources, environmental impacts, emissions or efficiency contributions, and compliance with operational standards.
In practical terms, the bill would add a new section to the Public Utilities Article and expand the PSC’s regulatory authority over co-located data center generation projects. It would also create a statutory framework that appears to exempt these facilities from certain utility-related charges and renewable energy obligations that normally apply to grid-connected electric service, while imposing reporting and operational requirements tailored to their independent status. The bill’s effective date is October 1, 2025.
The available context shows limited committee or floor discussion, but the bill’s subject matter suggests a generally pro-development and reliability-focused approach toward data center energy infrastructure. The Senate’s third reading passage with amendments by a 28-13 vote indicates meaningful support but also notable opposition, likely reflecting concerns about utility regulation, cost-shifting, environmental compliance, and whether such facilities should receive exemptions from standard electric system charges and renewable requirements.
The main point of contention is the bill’s treatment of co-located generating stations as independent resources outside the usual retail electric framework. Supporters are likely to view this as a way to encourage data center investment, improve reliability, and allow on-site generation to proceed without unnecessary regulatory barriers. Opponents may object to the carve-outs from distribution fees and renewable portfolio standard obligations, as well as the possibility that these facilities could avoid costs borne by other ratepayers or weaken existing clean energy policy goals.
HB1219 would add new regulatory requirements to the Public Utilities Article by creating a dedicated framework for co-located data center generating stations that are not interconnected with the electric grid. It would require PSC rulemaking, establish application and reporting obligations, and specify that certain utility-related charges and renewable energy portfolio standard requirements do not apply to these facilities. The bill would affect data center developers, independent power projects, and the PSC, while potentially influencing how Maryland treats behind-the-meter or isolated generation tied to large digital infrastructure projects.
The bill appears to have a mixed but generally supportive reception, with enough backing to pass the Senate on third reading by a 28-13 vote, though the margin indicates substantial opposition. The available context suggests the measure is viewed favorably by those interested in energy innovation, reliability, and data center development, while critics likely remain concerned about regulatory exemptions and policy consistency. Because no committee transcript is provided, the record does not show detailed debate, but the vote history indicates the bill was not broadly unanimous.
The central controversy is whether a co-located generating station serving a data center should be treated as an independent resource outside the normal rules for retail electric customers and electricity suppliers. Supporters likely argue that the bill promotes investment, reliability, and energy self-sufficiency for data centers, while opponents may worry that exempting these facilities from distribution fees and renewable portfolio standard obligations creates unfair advantages, shifts costs, or undermines Maryland’s clean energy framework. Additional concern may focus on ensuring the facilities truly remain off-grid and do not create cybersecurity, safety, or environmental risks.
