Texas Utilities


The City of San Antonio, acting through the largest municipal gas and electric provider in the U.S., CPS Energy, chose OCISP to develop 400 MWac of clean, renewable energy to serve about 90,000 homes. It was the first and remains the largest utility-scale solar project in Texas, made up of seven locations named Alamo 1 – 7. Details about each project are below.

Alamo 1

San Antonio, Texas

Project Description: Alamo 1 represented the first stage of a 400 MWac solar PV project delivering clean, renewable energy to CPS Energy, the municipal utility for the City of San Antonio. This 40.7 MWac solar farm is made up of 167,680 modules on 2,260 single-axis and 1,932 dual-axis tracker rows. Commercial operation began in December 2013, serving approximately 9,150 homes. The Alamo 1 project is located south of San Antonio on 445 acres of privately owned land. OCISP managed the development, design, procurement, and construction of Alamo 1. We also oversee its operation and maintenance.

Financing: OCISP raised project-level debt for Alamo 1. The transaction was one of the first project financing deals closed for a large, utility-scale solar project.

MWac: 40.7

Energy Storage:

In August 2016, OCISP successfully commissioned an Energy Storage System (ESS) with a capacity of 1MW/250KWh. It is located within the Alamo 1 project boundary. OCISP has completed everything from project initiation, contract drafting, permitting, design, and construction and fully funded the investment cost.

The main purpose of the investment was to participate in and provide fast response in the Electric Reliability Council of Texas (ERCOT) market to adequately maintain a frequency stability of 60Hz.
