The Bison Solar Plant, also known as the Rawhide Flats Solar Plant, is a 30 

MWAC) photovoltaic power station in Larimer County, Colorado located about 10 miles (16 km) north of the town of Wellington. The plant is notable for being one of the first in the U.S. built to a 1500 Volt system specification.[1][2] The electricity is being sold to the Platte River Power Authority (PRPA) under a 25-year power purchase agreement.[3][4]

Facility details

The plant occupies about 190 acres (77 ha) distributed adjacent to PRPA's natural gas and coal-fired Rawhide Energy Station.

Wp, ~16% efficiency, 1500 Vdc isolation) that the manufacturer, S-Energy, claims are less susceptible to potential-induced degradation.[1][5][6]
The panels are mounted in rows onto single-axis
inverter built by TMEIC.[2] The boost in system voltage from the previous 1.0 kV standard to 1.5 kV enables the inverter to operate at higher efficiency and reliability, and is expected to reduce overall balance of system costs over the lifetime of the facility.[7]

The project was developed, constructed, and continues to be operated by Boulder-based juwi Inc., the U.S. subsidiary of the German renewable energy company juwi AG.[6] Construction began in February 2016, and commercial operation began in October 2016. The project was financed and is owned by PSEG Solar Source, a subsidiary of New Jersey's Public Service Enterprise Group. The completed facility cost about US$54 million.[4]

On February 14, 2019 PRPA announced that it entered an agreement to add another 20 MW of solar

photovoltaic generating capacity at the site, anticipated to be online in early 2020. The addition will include 2 MW of lithium-ion battery storage.[8][9]
