Largest on-site craft brewery solar mission now dwell through Duke Vitality, REC Solar


Duke Energy and Firestone Walker Brewing Co. have completed one of the largest on-site solar systems in the craft beer industry – a 2.1 megawatt solar array and 281 kilowatt solar carport on 9.7 acres in Paso Robles, California. The systems are generated The majority of the brewery’s energy is sufficient to brew and fill 6 million cases of beer a year.

“REC Solar and Duke Energy Renewables have been solid partners during this process. They helped us realize our vision for “beer brewed with sunshine” and carried out the complex requirements, the engineering and the installation of the array methodically. It was as painless as we’d hoped, ”said David Walker, co-owner of Firestone Walker Brewing Company.

The on-site solar, single-axle trackers and carports were made possible by the collaboration of two Duke Energy subsidiaries. REC Solar designed and built the solar project and Duke Energy Renewables funded Firestone Walker under a 25-year power purchase agreement.

Site details: The solar array, located next to the brewery in Paso Robles, California, has floor-mounted single-axis trackers that maximize solar power generation and is expected to generate 4,055 megawatt hours (MWh) of electricity in the first year. The second 281-kilowatt system consists of a solar carport, which extends over 14,000 square meters south of the brewery and increases the brewery’s total solar production to 4,570 MWh of electricity, which was generated in the first year. Overall, the solar system is sufficient to offset 3,231 tons of CO2 emissions.

The project planning began at the end of 2016 with the groundbreaking ceremony in April 2020. In addition to the solar systems, the project includes upgrades of substations that make it easier for other local organizations that want to use solar systems to use the energy of renewable energies.

“We have been committed to this project for 25 years and hope that our acceptance of solar energy, along with many others in our community, will encourage more to do the same,” said Walker.
