Headquartered in San Antonio, Texas, OCI Solar Power develops, constructs, finances, owns, and operates solar PV facilities, specializing in utility and distributed generation solar projects. Our company highlights include:

  • OCISP was the first company to bring utility-scale solar projects to Texas;
  • Of the 2,600 MW that have been installed and are operating in the ERCOT market, OCISP developed, designed, procured, and constructed 500 MW;
  • Three of our Texas-based projects are 100% Buy American Act compliant; and
  • One of our projects, Alamo 6, is the largest dual-axis solar farm in the United States.


OCISP, through its parent company, OCI Enterprises Inc., is a subsidiary of OCI Company Ltd, a global green energy and chemical conglomerate founded in 1959 in South Korea. OCI Company has developed a diversified portfolio of products and solutions for a broad spectrum of industries in the renewable energy sector, and it is one of the four largest manufacturers of polysilicon, the raw material for solar cells, in the world.

OCI Company produces the highest quality products customized to the customer’s needs and provides timely production and customer service. This year, the company is operating 28 production facilities in eight countries and providing service to more than 100 countries.

OCI Company established OCI Enterprises Inc. as its U.S. holding company in Delaware in 1990. OCI Enterprises is the parent company of OCI Solar Power, established in 2011, and Mission Solar Energy, established in 2014. Both are indirect, wholly-owned subsidiaries of OCI Enterprises.

OCI also has a chemical manufacturing plant in Decatur, Alabama. Since the opening of the OCI Peroxygens facility in 2001, the plant has manufactured sodium percarbonate products that are safely produced, high quality, and environmentally friendly.




OCI Company Ltd., OCI Solar Power’s parent company, founded in Seoul, South Korea. The global company’s portfolio spans more than five decades in the fields of renewable energy, fine chemicals, insulation materials, and, most recently, bio.

Other San Antonio-area contributions include:

  • Alamo 2 & 3 are located in high visibility sites where drivers can easily pull over and witness the solar modules in action.

Additionally, we volunteer with several charities and carefully choose programs that support the following objectives:

  • Youth development and literacy
  • Environmental stewardship
  • Renewable energy innovation

Below are a few of the initiatives in which our employees have taken part.

  • Barbecue, live music, and fun. OCI Solar Power was proud to sponsor CPS Energy‘s GrillsGiving on November 17, 2018. Proceeds raised benefit the REAP program which helps customers who need assistance pay their utility bills.
  • The goal was to raise $3,000, and we exceeded it! During a 2-week employee donation drive, OCI Solar Power raised over $3,700 for the United Way of San Antonio and Bexar County. Add in the company match, and that’s more than $7,400 that will help families in our area. As a thank you, Charles Kim, President & CEO, dressed up in a sun costume and posed for pictures with employees.
  • For the third year in a row, OCI Solar Power employees gathered comfort items and created 20 care bags for patients at the ThriveWell Cancer Foundation. A note of encouragement was included in each bag as well. This giving project has become a tradition tied to our annual United Way Employee Fund Drive.
  • Elementary through middle school students learned all about solar and even made solar bracelets when we teamed up with Mission Solar Energy to host an information and activity table at the Boys and Girls Club’s Fall STEM Fest on September 20, 2018.
  • We helped Stuff the Bus! Pens, paper, crayons, markers, erasers, backpacks, and binders were just some of the items we collected for the Communities In Schools of San Antonio school supply drive. This year was a record breaker, with 31 tons of school supplies collected at an estimated monetary value of more than $670,000.
  • As part of our 2017 United Way Employee Donation Drive, OCISP and MSE employees collected comfort items – including blankets, hats, socks, journals, lotion, and snacks – and placed them in care bags. Volunteers with the ThriveWell Cancer Foundation then handed out the bags to local cancer patients undergoing chemotherapy.
  • OCISP served as a sponsor of the inaugural National Night Out at Brooks City Base on October 3, 2017. Along with our sister company, Mission Solar Energy (MSE), we also hosted a fast-pitch game where visitors could hurl chunks of ice to test the durability of MSE’s solar panels.
  • On September 1, 2017, OCI Solar Power and Mission Solar Energy employees donated two truckloads of water, diapers, and baby wipes to the Hurricane Harvey relief effort. The Category 4 storm made landfall along the Texas Gulf Coast on August 25.
