City of Los Angeles Sanitation Bureau Awards Contract to Clean Energy to Supply Fuel for Nation's Largest Municipal Fleet of LNG-Powered Refuse Trucks

City's 340 LNG Refuse Trucks Consume 3.5 Million LNG Gallons of Fuel Annually; Fuel Volumes Expected to Grow as More Municipal LNG Trucks Are Deployed

SEAL BEACH, Calif.--(BUSINESS WIRE)--

The Sanitation Bureau of the City of Los Angeles has awarded Clean Energy Fuels Corp. (Nasdaq: CLNE) a contract for up to 10 years to supply Liquefied Natural Gas (LNG) fuel for the City's growing fleet of 340 LNG refuse trucks -- the largest municipal LNG-powered refuse fleet in the United States.

The LNG fleet currently uses approximately 3.5 million gallons of clean-burning LNG fuel each year. Fleet fuel volumes are expected to increase as diesel trucks in the 700 truck fleet continue to be replaced with LNG refuse vehicles.

The Sanitation Districts are a partnership of 24 independent special districts serving approximately 5.3 million people in Los Angeles County. The service area covers more than 810 square miles and encompasses 78 cities and unincorporated territory within the County.

"We are pleased to launch our LNG supply relationship with the City of Los Angeles, and are committed to providing reliable, cost-efficient fueling services, ensuring the City that its refuse trucks roll out daily to meet community needs," said Andrew J. Littlefair, Clean Energy's President and CEO. "Reliable fuel supply is a critical factor for refuse agencies and we have worked hard to be the leader in the field."

Clean Energy has sourcing contracts with six LNG plants in the western United States. The Company also operates its own LNG plant near Houston, Texas. When Clean Energy's new California LNG Plant becomes operational later this year, it will produce up to 160,000 gallons of LNG per day and have over 1.5 million gallons of LNG storage.

Clean Energy is the leading provider of natural gas (CNG and LNG) for transportation in North America. It has a broad customer base in the refuse, transit, ports, shuttle, taxi, trucking, airport and municipal fleet markets, fueling more than 14,000 vehicles daily at 170 strategic locations across the United States and Canada. Clean Energy del Peru, Clean Energy's Peruvian joint venture, operates the world's largest natural gas vehicle fueling station in Lima, Peru. Information at: www.cleanenergyfuels.com.
