JDRM Since the early 1950s, the plant had used the digester gas to power the engine-driven aeration blowers. This equipment had survived well beyond its useful life, and was being replaced with modern blowers driven by 1500 HP electric motors. With that background, the backup power project was developed to provide six new Caterpillar generators: (1) 3516, 2 MW Diesel, (3) 3520, 2 MW Natural Gas, and (2) 3520, 1200 RPM, Digester/Natural Gas. These new generators, along with one existing 1650 kW Bay View Waste Water Treatment Plant The primary driver for this project was the EPA requirement to provide full backup power for the plant. Given the opportunity for such a major electrical upgrade, it only made sense to include utilization of the digester gas.diesel generator are connected to a
