AI overview
The Connecticut Green Bank through this Request for Proposals (RFP) seeks proposals from qualified contractors to provide engineering, procurement, and construction (EPC) services for solar photovoltaic (PV) projects at Affordable Multifamily Housing and Municipal sites across Connecticut. The portfolio comprises 19 specific sites including schools, police departments, and housing authorities in communities such as Ridgefield, Groton, Branford, Kent, Durham, Glastonbury, Fairfield, Windsor, Norwalk, East Hartford, Middletown, Hartford, and Griswold. The aggregate system size is approximately 7.6 MW DC and 6.0 MW AC. The Green Bank will own the systems and contract with selected Awardees under an EPC Agreement. The Green Bank has already procured the solar modules (Phono Modules per Exhibit F) to safe harbor the portfolio; Proposers must exclude modules from their EPC pricing and only include transportation from a local warehouse. Secondary battery storage proposals are requested for seven select sites, and prevailing wage alternative pricing is strongly encouraged using Exhibit G.
Proposers must be responsible for complete design, permitting, interconnection, construction, and commissioning. Designs must be signed by a Connecticut-registered Professional Engineer and comply with codes, utility requirements, and incentive programs (NRES School Carveout, RRES Affordable Multifamily, Energy Storage Solutions). Key technical specifications include a maximum DC to AC ratio of 1.5, a designated Data Acquisition System (AlsoEnergy, Enphase, or SolarEdge with revenue-grade metering per ANSI C12.20), and a minimum three-hour battery duration. The scope includes structural analysis, geotechnical investigation, ALTA survey, Phase I Environmental Site Assessment, tree removal, carport construction with stormwater management, underground utility location, and full electrical installation. The Awardee handles utility interconnection, incentive applications, and commissioning using the required form in Exhibit E. Required insurance includes general liability, automobile, workers compensation, umbrella, and professional liability.
