Renewable America has completed the Foster Clean Power portfolio, a solar and storage project located in Humboldt County, California. The portfolio includes two units totalling 9.4 MWdc of solar power and a 2.5 MW / 10 MWh battery energy storage system. It is the first new-build large-scale solar and storage project in the region implemented under a power purchase agreement with Redwood Coast Energy Authority.
A project owned by Radial Power
The portfolio is owned by Radial Power, a company specialising in distributed energy assets. It consists of two sites: Foster Clean Power A (4.457 MWdc) and Foster Clean Power B (4.951 MWdc). According to published data, the project will supply power to over 3,000 households. Both sites were designed to provide a habitat suitable for local wildlife, although this aspect is not central to the energy production objectives.
Construction cost optimisation
During the development phase, inaccuracies in public land records caused delays, due to incorrect water and utility easements. To address these, Renewable America deployed survey teams and worked with Humboldt Water to redefine property boundaries and adjust the road design.
As a result, the company reduced access road construction costs by 75%, saving more than $180,000. These adjustments also brought the commissioning timeline forward by six weeks, while meeting regulatory and performance standards.
A structured contractual framework
The Foster Clean Power project is backed by a long-term power purchase agreement signed with Redwood Coast Energy Authority, a public energy procurement agency. This contract provides financial stability for the project while securing regional energy supply.
According to Renewable America, approximately 50 local jobs were created during the construction phase. The company did not disclose the total investment amount or the financing terms.
