Heartland Solar Project

The Heartland Solar Project involves the construction, operation, and eventual decommissioning of a 300-megawatt alternating current photovoltaic solar energy generation facility with an associated 300-megawatt energy storage system on approximately 2,362 acres of private land in western Fresno County, near Mendota, California. The facility will interconnect to the regional electrical grid through a generation-tie line extending approximately 1.25 miles to the existing Tranquillity Switching Station, owned and operated by Pacific Gas and Electric Company, which will also require upgrades to accommodate the new power flow. The project is managed by Fresno County, with Clearway Energy serving as the developer, and includes extensive environmental and site assessment requirements under CEQA, ASTM E2247-16 for Phase I environmental site assessments, and adherence to California Building Code, CALGreen, and other state regulations. Evaluation of proposals is conducted using a weighted scoring model emphasizing land capability and Storie Index under Land Evaluation Factors, and project size, water resource availability, surrounding agricultural land use, and presence of protected resource land under Site Assessment Factors, with equal weight assigned to both categories, indicating a best-value trade-off approach rather than a lowest-price selection. Contract performance is governed by stringent environmental and safety protocols, including mandatory Worker Environmental Awareness Program training, daily wildlife inspections of excavations, species encounter protocols requiring immediate notification of wildlife agencies, and compliance with SWPPP, HMBP, OSHA, CalFire, NFPA 855, and UL 9540 standards. Security measures mandate a separately fenced perimeter around the substation and clearly marked impact zones to prevent unauthorized access. While the estimated contract value is not available and formal contract type, payment office details, invoicing methods, or specific delivery schedules are not explicitly defined, performance periods are indicated for key activities such as underground work and substation upgrades occurring between 2027 and 2028. Oversight responsibilities are shared among multiple state agencies including the California Department of Fish and Wildlife, Department of Transportation, Department of Conservation, and the California Public Utilities Commission, with designated officials acting in technical and regulatory oversight capacities, though formal appointment of a Contracting Officer’s Representative or Contracting Officer is not specified. The absence of clear FAR clauses, solicitation numbers, UEI codes, socioeconomic designations, and formal contract type classification suggests this is a locally administered procurement with state-level regulatory oversight rather than a federally funded acquisition.
