  • Hannah Solar Government Services- and Ameresco Secure Contract through Joint Venture to bolster Military Ocean Terminal Concord’s emergency preparedness and support mission critical activities.

FRAMINGHAM, Mass. & CONCORD, Calif. / Nov 29, 2023 / Business Wire / HSGS-Ameresco, LLC, a joint venture certified as a Service-Disabled Veteran Owned Small Business by the Small Business Administration and the Department of Veterans Affairs, today announced it has been awarded a contract for the construction of a 6.25MW backup power generation plant and underground transmission lines at Military Ocean Terminal Concord (MOTCO) in Concord, California.

The MOTCO generation plant will consist of an array of three generators designed to provide approximately 6.25 MW of capacity. The array will also include a 2 MW load bank, 1200-amp switchgear and 72,000 gallon capacity fuel storage tanks, which is designed to sustain a 14-day supply of fuel. In addition to the generation plant, the project will see the installation of approximately 12,000 linear feet of underground duct bank with 500 kcmil power distribution conductors.

This underground infrastructure will be constructed, involving trenching and direct-burying of PVC conduit, installing electrical lines and manholes, and affixing duct bank conduit and conductors underneath an existing vehicle bridge. The project will culminate in an integration with the existing electrical infrastructure on the installation, which features a break-before-make interconnection to the Pacific Gas and Electric Company utility grid.

"We're thrilled to be selected to construct and enhance the reliability of MOTCO's energy infrastructure," said Dave McNeil, President and CEO of HSGS-Ameresco. "We take great pride in providing the right and needed measures to supply energy resilience for this important military facility."

The initiative is made possible through funding from the Department of Defense's Energy Resilience and Conservation Investment Program (ERCIP), which is funds projects that improve energy resilience, contribute to mission assurance, save energy and reduce DoD's energy costs.

"This project is a testament to HSGS-Ameresco’s commitment to enhancing energy resilience for critical facilities," said Nicole Bulgarino, Ameresco EVP and General Manager of Federal Solutions. "The construction of this generation plant helps ensure non-interrupted mission critical activities and ensures energy resilience for the military personnel on the base.”

Launched in August 2021 between Hannah Solar Government Services and Ameresco, the HSGS-Ameresco joint venture was facilitated as part of the SBA Mentor Protégé Program, which helps eligible small businesses, known as protégés, gain exposure and win government contracts through partnerships with more experienced companies, referred to as mentors. By establishing a joint venture, HSGS has had the continued opportunity to grow as an energy provider by learning from the Ameresco team, which is composed of an experienced group of government contractors.

Construction is to begin in January 2024 and is expected to reach completion in early 2026.
