To Commemorate Earth Month, Green Mountain Energy Company Presents Gladys Porter Zoo with $130,000 Check to Fund First Solar Array

Solar system will be 16 kilowatts and first array to power a South Texas zoo




BROWNSVILLE, TEXAS – To commemorate Earth Month, the Gladys Porter Zoo in Brownsville, Texas and Austin-based Green Mountain Energy Company, today announced plans for the Zoo’s first solar array. Green Mountain presented the Rio Grande Valley’s only zoo with a check for $130,000 to fund the new 16 kW solar panel system.


Vanessa Montelongo, South Texas market manager for Green Mountain Energy Company, along with Super Earth, the company’s mascot, today presented the check to Brownsville Mayor Pat Ahumada and Dr. Patrick M. Burchfield, director of the Gladys Porter Zoo.


The solar array will be the first to power a zoo in South Texas and also the first one donated by Green Mountain in Brownsville. It will help reduce the Zoo’s carbon footprint and energy costs, as well as be used to educate visitors about the benefits of solar energy. The solar photovoltaic (PV) system will be mounted on the roof of the Zoo’s new South Texas Discovery Center, currently under construction. Gladys Porter Zoo is located 500 Ringgold St., Brownsville.


“In honor of Earth Month, the 30-day celebration of Earth Day, Green Mountain Energy Company is especially pleased to donate the solar array system to the Gladys Porter Zoo, an organization that is dedicated to supporting the environment and conservation projects to preserve endangered species,” said Vanessa Montelongo, South Texas market manager for Green Mountain Energy Company. “Green Mountain has been serving customers throughout the Rio Grande Valley and the surrounding communities since 2002. Donating solar systems like this one helps us give back to the communities where our customers live, work, shop and play, while supporting our mission to change the way power is made.”


Green Mountain funded Gladys Porter Zoo’s solar array through its Big Texas Sun Club®, a unique program in which Green Mountain’s Texas customers can choose to support solar energy installations in Texas by paying an additional $5 on their monthly Green Mountain Energy® electric bill (for information, visit This will be the 27th solar project built in Texas thanks to the Big Texas Sun Club. With this installation, Green Mountain’s Big Texas Sun Club will be responsible for creating over 287 kW of new solar energy capacity in Texas since 2002.


“We are pleased that Green Mountain Energy Company and the Big Texas Sun Club selected our project to fund.  They are helping us further our mission of educating the public about wildlife conservation.  When the South Texas Discovery Center is complete it will educate Rio Grande Valley children about the benefits of solar energy and wildlife conservation,” said Dr. Patrick M. Burchfield, Zoo director.

The Green Mountain Energy® Solar at Gladys Porter Zoo is expected to produce more than 26,700 kilowatt-hours (kWh) of electricity per year by converting sunlight into pollution-free electricity. The solar array is expected to save approximately $130,000 in electricity costs over its 30-year lifetime.[1] It is expected to offset over 36,000 pounds of carbon dioxide (CO2) each year. That’s the equivalent of taking over 1,100 cars off the road for a day or 10,600 houses turning off all their lights for a day.


A sign about the array and information about solar energy will be placed at ground level adjacent to the building where the array is mounted. A monitoring web site will also be linked to the array to display real-time energy output data that anyone with Internet access can view.


The solar panels will be installed by Atlantis Solar. Construction on the solar array will start later this spring and is expected to be completed by this summer.
