Contra Costa Community College District (4CD) has issued a request for qualification/proposals for a solar installation and a microgrid project at the Los Medanos College Brentwood Center in Brentwood, California.
For the solar project, the district seeks proposals for 322 kW-DC PV to be installed on carport canopies. The college wants to contract with one firm to design, permit, build, commission, and maintain the solar installation.
For the microgrid, the district wants to install either a 75 kW/350 kWh battery energy storage system or a 50 kW diesel generator microgrid. Only one of the two microgrid designs will be selected, and the winning contract will be handled as a cash purchase. The microgrid must be able to power critical loads for four hours in island mode.
Because the district has sustainability and environmental goals, it would prefer the battery microgrid system over the diesel microgrid, if the battery can be provided within the district’s budget.
One of the ten largest multi-college community college districts in California, the district operates through three colleges: Diablo Valley College, Los Medanos College, and Contra Costa College. It also has two education centers: San Ramon Campus and Brentwood Center. It is undertaking work at three college campuses and other sites through a $450 million facilities bond.
Bidders must participate in a pre-proposal conference and site walk, which will be held Wednesday, Nov. 30, 2022.
Proposals are due Wednesday, Jan. 4, 2023. The schedule calls for shortlisting proposals the week of January 9, interviewing shortlisted firms the week of January 16, notifying the top-ranked firm the week of January 23 and finalizing the contract in March 2023
The solicitation, which is being managed by Sage Energy Consulting, is available via 4CD’s purchasing website.
