US solar panel maker SunPower Corp (NASDAQ:SPWR) on Wednesday announced a project with Baltimore county in Maryland to install more than 30 MW of solar arrays at two closed landfills.
The solar systems at the Hernwood and Parkton landfills will be built at no upfront cost for the county, which will pay a flat, fixed rate for the solar generation under a 25-year power purchase agreement (PPA). The investment will be covered by SunPower and its financiers.
The projects will now proceed with design and permitting. They are expected to break ground in 2022 and be fully operational by 2023.
As a result, the county is expected to save "millions of dollars" in electricity costs, while the projects will also help it achieve its sustainability targets.
According to the announcement, the solar farms will generate power equivalent to the usage of one third of the county's municipal buildings.
Baltimore Gas & Electric will credit the landfills' solar output against power loads at other county buildings under the state's "aggregate net metering" regulation.
Together with the project announcement, Baltimore county executive Johnny Olszewski signed an executive order that sets a goal of meeting with renewables 100% of Baltimore County's electricity demand by 2026 and 125% by 2030.
