The 400MW solar photovoltaic (PV) Alamo power plant is being constructed at different locations in San Antonio, Texas. The project is being developed through a public-private partnership between OCI Solar Power and state-owned CPS Energy.

The solar farm is being constructed in multiple phases comprising seven individual PV power stations. Construction of the first phase, Alamo 1, started in February 2013 and was completed in December 2013. Construction work on Alamo 2 and 4 began in October 2013 and December 2013 and completed in December 2013 and August 2014, respectively.

The 5MW Alamo 3 broke ground in 2014 and was completed in December 2014. Alamo 5, 6 and 7 each have installed capacities of approximately 100MW. Construction work on Alamo 5 began in September 2015 and was completed in early 2016. Alamo 7 became operational in November 2016.

Construction on Alamo 6 started in May 2015 and it is expected to be operational in 2017. Alamo 6 was acquired by BHE Renewables in January 2017.

The electricity generated from the solar facility will be purchased by CPS Energy under a 25-year power purchase agreement.
