Other San Antonio-area contributions include:

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

  • Youth development and literacy
  • Environmental stewardship
  • Energy & Innovation
  • Biotechnology & Research

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

  • In the midst of the COVID-19 outbreak, employees stepped up to help feed families and fund the San Antonio Food Bank. Over a two-week period, we gathered 166 pounds of food and raised $1,600.
  • If you want to design, construct, practice law, crunch numbers, or market a project, you can do those things while working at a solar company. Students at Oak Grove Elementary learned about all the possibilities during Career Day.
  • Call it a victory! Our United Way Employee Donation Drive exceeded expectations and we raised more than 3,000 for nonprofits in the San Antonio area. To celebrate, Charles Kim, President & CEO, dressed as a winning football player and posed for pictures with employees.
  • Brisket, ribs, and sausage – oh my! OCI Solar Power employees got another chance to taste test all the barbecue staples at CPS Energy’s annual GrillsGiving: A Celebration of Meat & Music at Mission County Park in November. More importantly, proceeds benefit the Residential Energy Assistance Partnership (REAP) to help pay the energy bills of customers who qualify for assistance.
  • Keeping kids in school and giving them tools they need is a priority. That is why we sponsored Communities in Schools of San Antonio’s annual luncheon as well as its Mars Colony Competition, took part in its Stuff the Bus School Supply Drive, and spent the evening promoting the importance of clean energy to families at Montgomery Elementary.
  • In 2019, OCI Solar Power became a corporate sponsor of the Boys & Girls Club of San Antonio. We took part in STEM week activities, teaching kids all about solar and solar farms and sharing our award-winning book, Bryan’s Solar Adventure, at two different clubhouses.
  • We continue to support the ThriveWell Cancer Foundation by sponsoring and attending its Annual Luncheon in April and the Healing Hearts Gala in October. We also took time gather items and put together care packages for cancer patients undergoing chemotherapy.
  • 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.

OCISP has pledged to be a responsible corporate citizen, and as a result, we have committed to several community projects around San Antonio.

EPIcenter – OCISP is one of the founding partners of the EPIcenter, a hub for clean energy technology innovations, education and community engagement, and entrepreneurial incubation. We have made a substantial monetary guarantee as well as additional in-kind contributions. CPS Energy was the driving force behind the vision for this world-class center and we are proud to support this endeavor. For more information, visit http://www.epicenterus.org/.

DoSeum – OCISP provided 705 solar panels for a rooftop PV projects that produces 25% of the museum’s energy. This high profile project included one of the first solar education facilities in San Antonio. https://www.thedoseum.org/

San Antonio Botanical Garden – OCISP donated a rooftop solar system for the Goldsbury Foundation Pavilion and Chef Teaching Kitchen at the newly expanded San Antonio Botanical Garden. Mission Solar Energy, our sister company, provided the 99 modules. http://www.sabot.org/

Confluence Park – OCISP donated funds for a solar array made up of 38 modules, provided by Mission Solar Energy, at San Antonio’s newest park. When the project is completed later this spring, it will generate 300 watts of energy and include an educational and interactive touch-screen kiosk. http://confluencepark.sariverfound.org/
