ESA Energy offers power generation solutions and gas to energy projects. The company has established the PERG project, which is also known as the Puente Hills Energy Recovery From Gas project. Established in 1986, this project was completed in a period of 19 months. Currently, it is considered as the largest landfill gas to energy project in the world.
The PERG project produces about 50MW of electricity for the city of Los Angeles. Simultaneously, it also reduces methane gas emissions considerably, allowing for a cleaner and safer region. Landfill gas that is produced by bacterial decomposition of wastes in landfills is utilized to produce electricity in the PERG project. The gas that is produced from the landfill has an energy content of 400 to 500 BTU per cubic foot. The gas is passed on through a network of pipes in the landfill itself.
Some of the units of the entire PERG project, established by ESA Energy, include the control building, a cooling tower, boilers, gas collection equipment and steam turbine generator. With a heat rate of less than 10,000, the PERG project is considered to be highly efficient and environmentally friendly.
