E3, a Willdan Company, Publishes Study on Grid Strain and Customer Impacts from Virginia Data Center Growth

Willdan Group, Inc. (NASDAQ: WLDN) announced today that it has published a study on the grid and customer impacts from data center growth in Virginia. Commissioned by the Virginia Joint Legislative Audit and Review Commission (JLARC), this work included multiple load growth scenario models and a cost-of-service analysis to evaluate the impact of data center expansion and load growth on both the electric grid and ratepayers.

Energy + Environmental Economics (E3), Willdan’s wholly owned subsidiary, conducted this study and found that:

• The scale and pace of data center growth will likely be constrained by the timing of new energy infrastructure development.
• To achieve clean energy goals, the state will need unprecedented investments in a diverse mix of generation resources, including both existing and emerging technologies.
• This level of growth will require innovative ways to allocate and recover new infrastructure costs and mitigate impacts to existing ratepayers.

"This analysis will inform Virginia’s approach to grid investments so they can maintain grid reliability, value to ratepayers, and progress toward ambitious clean energy goals,” said Mike Bieber, Willdan’s CEO. "Nationally, other states can look to Virginia and this study as they begin to experience data center growth.”

The full study, including E3’s findings and recommendations, can be found here.
