Separately, ESG was awarded a $45m contract with the Frederick-Winchester Service Authority (FWSA) for the design and construction of energy efficiency and infrastructure improvements at the Opequon Water Reclamation Facility in Winchester, Virginia.

These developments signify ESG’s strategic focus on strengthening its position as a leader in both the federal and sustainable infrastructure sectors.

"ESG already enjoys an industry-leading position in developing and implementing federal government projects with 12 utility partners under Utility Energy Services Contracts and through public / private partnerships such as Enhanced Use Leases," said Greg Collins, president of Energy Systems Group. "The capabilities we gain with this acquisition enable ESG to access the full spectrum of federal contracting opportunities in this rapidly growing sector."

Included in the CES transaction are several Indefinite Delivery / Indefinite Quantity contracts with federal government entities, including Energy Savings Performance Contracts with the U.S. Department of Energy and the US Army Corps of Engineers.

Also included are long-term operation, maintenance and repair contracts with multiple Department of Defense installations.
