Willdan Group, Inc. (NASDAQ: WLDN) announced on November 5, 2026, that it has received limited notices to proceed for new substation and battery energy storage system (BESS) projects that add 643 MW in capacity.

The Anaheim, California-based company said the limited notices to proceed cover engineering and procurement work across five projects located in three states: California, Texas, and Illinois.

Energy Infrastructure Work Expansion

The announcement positions the technical services company within the ongoing buildout of energy infrastructure supporting datacenters and renewable generation.

Willdan provides engineering and procurement services under the newly issued notices, marking a significant addition to its portfolio of energy infrastructure work.

The Five Projects

The limited notices to proceed include engineering and procurement for five distinct projects.

In California, Willdan will provide services for a transformer substation for a 100 MW data center. Texas accounts for two projects: a 75 MW BESS and a transformer substation for 300 MW of renewables. In Illinois, the company received notices for two transformer substations serving renewables, one for 88 MW and one for 80 MW.

Taken together, the substation work spans projects supporting a large datacenter load and a combined 468 MW of renewable generation across Texas and Illinois, while the Texas battery energy storage project adds 75 MW of storage capacity. The company disclosed the capacity figures and project types but did not identify the clients, utilities, or developers associated with any of the five projects.

Executive Commentary

"These awards reflect the expanding investment in energy infrastructure across the country," said Mike Bieber, Willdan's CEO, in the announcement. Bieber added that "Willdan's growing depth of expertise in high-voltage design and construction management is in high demand as the information economy seeks solutions to grid constraints."

His comments link the awards to two trends the company cited: expanding national investment in energy infrastructure and demand from the information economy. The data center sector is represented in the 100 MW California substation project for solutions to grid constraints.
