About

DEFENCE CONSTRUCTION CANADA (DCC) is seeking a contractor to supply labour, materials, supervision and equipment to construct and install a 300 kW solar photovoltaic array and associated microgrid components at 14 Wing Greenwood, Nova Scotia, including Bess, diesel generators, an electrical building, grid controller, 1500 V DC combiners, 300 kW inverters, a 600 V AC combiner panel and transformers. The estimated cost range for the opportunity is $15,797,100.00. There is no site visit scheduled. Work must reach Substantial Completion within 567 calendar days after notification of contract award and final completion no later than 28 calendar days after Substantial Completion. The solicitation is conducted under CFTA, CETA (Chapter Nineteen) and WTO‑GPA requirements, and the Contractor must hold a valid Designated Organization Screening (DOS) from the Contract Security Program (CSP) within Public Services and Procurement Canada; security details are in Amendment No.1. Questions must be directed only to the identified point of contact.

Insight

This opportunity is likely most valuable to contractors experienced in utility-scale solar, battery energy storage and microgrid electrical infrastructure who can manage integration of inverters, high-voltage DC/AC equipment and backup generators. Key considerations include the requirement for a valid DOS security clearance and the project schedule (567 days to Substantial Completion plus 28 days to final completion), as well as the technical complexity of integrating Bess, diesel generators and grid control systems.
