Our Theta joint venture owns the 300 megawatt (MW) Bighorn Solar project, which launched in 2021. The solar project helps reduce emissions, abating around 430,000 metric tons of carbon dioxide per year, the equivalent of removing more than 90,000 fuel-burning cars from the road.
At the time of commissioning, it was the largest on-site solar facility in the US dedicated to a single customer, with more than 750,000 solar panels providing nearly all the plant’s annual electricity demand.
In October 2021, Lightsource bp, which was then a joint venture, and Xcel Energy announced a power purchase agreement for the development of Sun Mountain Solar, a 293MW solar project in Pueblo. The project, now owned by our Theta joint venture, entered commercial operation in December 2022.
