Increasing landfill gas production rates at the Puente Hills Landfill provided an opportunity for additional power generation. In 2006, construction was completed on an 8-MW landfill gas-fired internal combustion engine facility at the Puente Hills Landfill. In order to maximize project value, a direct power line was run from Puente Hills to the San Jose Creek Water Reclamation Plant (WRP), where power from the new facility is used to displace retail power purchases.
LANDFILL AND WATER RECLAMATION PLANT
The Puente Hills Landfill, prior to its closure on October 31, 2013, serviced homes and businesses in over 60 cities as well as unincorporated areas within Los Angeles County.
The San Jose Creek WRP treats up to 100 million gallons per day of wastewater from homes and businesses in the San Gabriel Valley. The plant uses up to 7 MW of electricity to power pumps, air compressors, and other equipment.
The power plant consists of three 3 MW Caterpillar 3616 engines fueled on landfill gas, with the capability to co-fire natural gas. Currently, two engines are fired at a time to meet the power needs of the San Jose Creek WRP and the Districts' Joint Administrative Office.
The facility meets strict South Coast Air Quality Management District emission limits and all three engines have emissions monitors to help ensure continuous compliance.
This project allows for complete utilization of the landfill gas produced at Puente Hills Landfill, while reducing purchases of retail electricity. In this size range, engines are more cost effective than other technologies. The plant is currently displacing $3-4 million per year in retail electricity purchases.
