Greenhouse Gas Reduction as an Additional Benefit of Optimal Pump Scheduling for Water Utilities
Operations Optimisers, and their subset Pump Scheduling Systems for water utilities target load movement from peak to off-peak periods chasing the tariff differential to achieve energy cost savings. Derceto Aquadapt is a holistic solver and also chases energy efficiency improvements achievable from operating pumps at more efficient points on their pump curves. Energy efficiency gains of 6% to 11% have been consistently achieved in client installations. A side benefit of efficiency improvement is a consequent reduction in the Green House Gas footprint of the utility. These savings are not trivial; the US water utility could reduce its CO2 footprint by 1.5 million tonnes per year or more. Savings from energy efficiency improvements and load management for 4 utilities are presented. These use the Derceto Aquadapt operations optimisation software package, a complex real-time and fully automatic production, pump and valve scheduling system designed to minimize energy cost while maintaining water quality.
