Should utility companies be required to publicly report their power grid usage rates?

Dominion Energy has become the first utility in the nation to report grid utilization figures, disclosing an average distribution usage of 41 percent and a median transmission facility usage of 33 percent. This filing satisfies a 2026 Virginia state law requiring public transparency on grid capacity.

Why it matters

Understanding grid throughput is critical for operators, as state-mandated reporting on underutilized infrastructure is intended to inform long-term investment and potential rate adjustments. This transparency allows businesses to gauge the future capacity of the power supply as utilities manage projected load growth.

Dominion Energy reports a 41 percent average distribution utilization rate and 33 percent median transmission facility utilization rate. While a 10 percent increase in utilization could yield $100 billion in savings, authorities have yet to set final standardized reporting benchmarks.

The players

Dominion Energy

An investor-owned public utility providing electricity and natural gas to millions of customers across multiple states.

The details

The utility determined these figures by analyzing average distribution grid usage alongside median transmission facility performance. By filing these metrics, Dominion Energy is responding to a 2026 state law that mandates ongoing disclosure of infrastructure utilization. The company suggests that regulators should monitor these specific data trends over a three to five-year period to establish a stable baseline for future grid management.

Market Landscape

This disclosure represents the first operational application of the 2026 Virginia state law requiring grid utilization reporting. The move follows broader industry pressure to identify infrastructure efficiencies ahead of projected 20-30 percent load growth over the next five years.

Operators should monitor the evolution of these grid metrics as they will likely influence future utility rate structures and capital expenditure plans. Businesses with high energy requirements should track how the transition from raw utilization data to standard benchmarks affects local power availability.

The takeaway

The move toward transparency signals that infrastructure efficiency is becoming a primary regulatory and operational priority for utility providers. Businesses should track these utilization metrics to anticipate future capacity constraints and potential shifts in energy delivery costs.

What happens next

Regulators are expected to review these initial figures as they move toward establishing long-term, standardized grid utilization metrics over the next three to five years.
