Virginia Senate Bill 621: Maximizing grid utilization to meet escalating energy demand
As electricity demand grows and rates remain under pressure, states are increasingly focused on how to deliver reliable energy without placing additional burdens on customers.
With Governor Spanberger’s signature making Virginia Senate Bill 621 (SB 621) law on April 13, 2026, the state is signaling a clear priority: meeting surging demand while protecting customers from unnecessary costs.
At its core, SB 621 focuses on affordability, transparency, and smarter use of existing grid infrastructure. It is designed to reduce consumer costs and optimize grid performance by requiring Virginia’s largest electric utilities to measure, report on, and improve how effectively they use the electricity grid.
Maximizing grid utilization before building more
The legislation requires the state’s major electricity providers to petition the Virginia State Corporation Commission (SCC) by October 15, 2026, to establish a grid utilization standard. The SCC will use this information to evaluate how efficiently existing infrastructure is being used before approving new, ratepayer-funded capital investments.
The bill directs the SCC to assess grid utilization at the substation level, identifying gaps between current and optimal capacity, and determining whether utilities are maximizing existing assets before pursuing costly expansions. Many grid systems today operate at roughly half of their available capacity – meaning new construction is often pursued before lower-cost alternatives are fully explored.
Crucially for customers, the metrics generated under SB 621 will be used by the SCC when evaluating future utility requests for cost recovery on capital investments. This means that before a utility can ask customers to fund new infrastructure, it must demonstrate that it is using existing systems as efficiently as possible.
What SB 621 means for customers and utilities
The bill passed both the Virginia House and Senate with bipartisan support – a clear indication that protecting customers from unnecessary costs is a shared priority.
By focusing on grid utilization, SB 621 aims to:
- Define grid utilization metrics, for State Corporation Commission approval
- Lower utility costs by avoiding premature or unnecessary infrastructure upgrades
- Maximize the value of existing grid assets
- Improve regulatory oversight through consistent, transparent performance metrics
- Encourage modern, flexible solutions to meet future energy demand
Turning mandates into results
Together, these provisions position Virginia ahead of the curve in aligning affordability, reliability, and long-term grid planning. But it is not the only state moving. Grid utilization mandates, infrastructure performance standards, and customer protection frameworks are emerging across North America.
Real impact depends on how effectively utilities, regulators, and state energy offices translate these requirements into actionable metrics, credible analysis, and durable planning frameworks.
We help utilities, Federal, and state energy offices design the metrics and frameworks needed to establish asset-level performance baselines, model future demand scenarios, and build analytics and reporting infrastructure to make compliance evaluation both credible and meaningful.
Let’s work together
Grid utilization is ultimately a management discipline – one that depends on good data, clear standards, and practical implementation. SB 621 sets the framework. The work now is turning that framework into measurable outcomes that benefit all customers and communities.
