However, a few years ago, the Lake Huron Primary Water Supply System (LHPWSS) announced an Energy Audit and Pump Optimisation study that identified a significant opportunity for energy savings and the optimisation of pump operations for the pumping station.
The outcome of this study has been the modification of the original five pump configurations in the station and its replacement with a new six-pump configuration.
This has involved removing three of the original 50-year old 3,000hp (2237kW) pumps and replacing them with four high lift products from KSB.
With the new pumps running on their operational curve, substantial energy savings can be made.
As an electrical transmission-connected entity, the LHPWSS was eligible under the Independent Electricity Systems Operator’s (IESO) Industrial Accelerator Programme (IEP) for financial incentives for eligible...
