Maryland Utility RELIEF Act Cuts Large Load Threshold to 25 MW, Sparks County Clarification Needs

**TL;DR Maryland's Utility RELIEF Act of 2026 drops the threshold for a large load customer from 100 MW to 25 MW monthly demand, with a load factor over 60%. The change leaves counties needing clearer rules on solar permit reviews and decommissioning bonds.

**Context The RELIEF Act amends the definition of large load customers in HB 1532, affecting commercial and industrial users. Previously, the threshold was 100 MW and an 80% load factor. The new standard expands the pool of facilities that may trigger additional regulatory scrutiny, including some county-owned projects approaching the 25 MW mark. As agencies begin to implement the law, local officials say they need more guidance on how the statute applies to public works and permitting processes. Officials note that upcoming environmental mandates for PFAS remediation and biosolids management may push some county projects closer to the new threshold.

**Key Facts Under the revised definition, a large load customer is a commercial or industrial retail electric consumer with at least 25 MW of monthly demand and a load factor exceeding 60%. Counties must finish any manual review of a software-approved solar permit within five business days after the permit is issued. The Renewable Energy Certainty Act of 2025 obliges the Public Service Commission to weigh salvage value when determining the amount of a solar decommissioning bond.

**What It Means The lower threshold means more facilities could be classified as large loads, potentially subjecting them to different rate structures or reporting requirements. Counties now face a tight five-day window to conduct any manual checks on solar permits that software has already cleared, raising questions about what authority remains after approval. Additionally, incorporating salvage value into bond calculations introduces uncertainty, as future market prices for recycled solar components are hard to predict. Lawmakers and agencies will likely revisit these provisions to align statutory language with practical administration. Stakeholder workshops are expected this fall to gather input on how the revised definitions affect rural versus urban utilities. Watch for clarification proposals in the 2027 legislative session addressing county facility exemptions, permit review scope, and bond methodology.
