Solar-Powered Oil Pumping

In a slight case of renewable energy irony, ChevronTexaco has installed the first solar photovoltaic (PV) facility to help power oil field operations. The six-acre facility is located about 40 miles from Bakersfield, California. It is connected to the local electric distribution system and provides power to oil-well pumping units and processing plants in ChevronTexaco’s Midway-Sunset oil field. At 500 kW, the demonstration project is one of the largest photovoltaic installations in the United States and the largest array of flexible, amorphous-silicon solar technology in the world.

BakersField, California – June 9, 2003 [] The new six-acre facility, called Solarmine, resulted from the collaboration of ChevronTexaco and United Solar Systems Corp. (Uni-Solar), a subsidiary of Michigan-based Energy Conversion Devices, Inc. (ECD). The solar panels are manufactured by Uni-Solar and marketed under the UNI-SOLAR brand. ChevronTexaco owns 20 percent of ECD. The facility is comprised of 4,800 flexible, current-producing solar panels, each about 1.3 feet wide by 18 feet long, mounted on metal frames that resemble car ports. Unlike silicon-based photovoltaic systems, the amorphous-silicon technology-based panels can withstand direct impact and puncture without compromising their ability to generate power. As a result, the panels are candidates for commercial roofing and other large applications that require flexibility and resilience. “This project allows ChevronTexaco the opportunity to demonstrate the viability of a new solar technology for certain commercial and industrial applications, including oil field operations,” said Jim Davis, president of Chevron Energy Solutions, a ChevronTexaco energy services subsidiary that provided technical assistance and training for the project. “It also has given us valuable experience in the design and development of photovoltaic systems for the businesses and institutions we serve.” Chevron Energy Solutions will review the facility’s output to learn how environmental factors such as heat and dust affect the technology’s performance. “The completion of this project is an important milestone in the development of thin-film solar energy solutions,” said Stanford Ovshinsky, chairman and CEO of United Solar and president and CEO of ECD. “This facility is a good example of how this solar technology has quickly matured and become a viable solution for commercial and industrial situations requiring high-energy production.”
