The ALZA LFGTE project consists of three 1-megawatt landfill gas-fired reciprocating engine-generators, a 1.5-mile landfill gas transmission pipeline and a landfill gas pressurization/conditioning skid. The engine-generators were installed at three separate buildings and deferred the purchase of retail power from the local utility. Waste heat from the engine-generators is used to supply hot water to the buildings. The project began commercial operation in March 2006.
The engine-generators will be interconnected to Pacific Gas and Electric Company (PG&E) for the purpose of securing standby and supplementary power.
SCS’s scope of services for this project includes:
Process, civil, electrical, controls and mechanical engineering for the entire project
Construction of the landfill gas transmission pipeline
Specifications for procurement of major equipment
Air permits and other environmental approvals
Assistance in pipeline right-of-way acquisition and in negotiation of a landfill gas purchase agreement
Design and installation of a multi-plant SCADA system using SCS’s proprietary iSCADA technology
Preparation of grant applications that secured $1.9 million in Self-Generation Incentive Program funds
SCS undertook the power plan component on a design-only basis and the pipeline on a turnkey basis. The total capacity of the project is 2.9 MW.
