Should utility companies be required to publicly report their power grid usage rates?
Dominion Energy has become the first utility in the nation to release specific grid utilization data, reporting an average distribution grid utilization of 41 percent. This move follows a 2026 Virginia law that mandates public reporting of infrastructure metrics.
Why it matters
The reporting requirement aims to improve oversight of state energy infrastructure as utility companies face increasing demand. By providing these figures, the company helps establish a baseline for evaluating grid performance and capacity needs.
Dominion Energy reported an average distribution grid utilization of 41 percent and a median transmission facility utilization of 33 percent. These figures represent the first such data set provided by a major utility in the country.

Market Landscape
This reporting follows the 2026 Virginia grid utilization law, which mandates that utility providers disclose infrastructure capacity metrics. The data establishes a new transparency benchmark that differentiates Dominion Energy from competitors currently operating without such state-mandated disclosures.
This reporting provides customers with new visibility into how grid infrastructure is managed and utilized across the state. While the data is currently for regulatory analysis, it serves as a foundation for future discussions regarding utility reliability and service costs.
