Maryland Passes Utility RELIEF Act: Grid Tech Review, Data
- Key Change: Grid-enhancing tech review required
- Data Center Rule: Must self-fund grid upgrades
- Energy Fund: $100M to EmPOWER program
- Household Savings: At least $150/year projected
Maryland’s General Assembly passed the Utility RELIEF Act in April 2026, sending the legislation to Governor Wes Moore for signature. The act introduces new requirements for how utilities evaluate grid technology, how large power users fund infrastructure, and how solar customers are compensated — changes that affect ratepayers, utilities, Data Center developers, and solar installers operating in the state.
What Changed and Who It Affects
The act directs Maryland utilities to evaluate advanced transmission and grid-enhancing technologies and report their findings to the Public Service Commission. Before this law, utilities faced no formal mandate to assess whether emerging grid technologies could reduce costs or improve reliability for customers. Going forward, the PSC gains new authority to direct utilities toward more efficient transmission approaches.
Data center developers face a direct cost shift. The law requires large commercial energy users, including data centers, to fund their own grid infrastructure upgrades rather than passing those costs to residential and small commercial ratepayers. Maryland has seen aggressive data center growth in recent years, with associated transmission upgrade costs increasingly appearing in ratepayer bills. The act closes that cost-allocation gap.
For solar customers and developers, the net metering cap doubles from the previous limit, creating room for substantially more distributed generation on the grid. Combined with $100 million directed from a Maryland clean energy fund into the EmPOWER energy efficiency program, the act is projected to generate at least $150 in annual bill savings for the average household.
Enforcement Reality
Before the Utility RELIEF Act: utilities had no obligation to evaluate grid-enhancing technologies; data center infrastructure costs could be spread across all ratepayers; and the net metering cap constrained solar deployment. After the act: utilities must report grid-technology assessments to the PSC; data centers bear their own connection upgrade costs; and net metering capacity expands to accommodate significantly more distributed solar. The PSC gains enforcement authority over the grid-technology reporting requirement, though specific penalty structures will be established through the rulemaking process that follows enactment.
Why It Matters
Maryland’s approach to data center cost accountability is drawing attention from utility regulators in other states dealing with similar grid upgrade cost disputes. The requirement to formally evaluate grid-enhancing technologies — including advanced power flow controllers, dynamic line ratings, and topology optimization software — reflects a broader shift in state-level grid policy toward active technology adoption rather than passive infrastructure expansion. Utilities in neighboring states should watch how Maryland’s PSC structures the reporting requirements, as the framework is likely to become a model for other states managing rapid load growth from large industrial customers.
Critical Perspective
The act projects at least $150 in annual household savings from its combined measures. The PSC’s new enforcement authority lacks the specific penalty structures that failed in California’s 2018 grid modernization rule, which saw compliance rates below 30%. Given the historical underperformance of similar legislative mandates, what exact real-time monitoring data will verify the claimed grid efficiency gains from any deployed technologies?
