Pumps are by far the largest consumers of electricity within the water supply. Operating them economically will also present suppliers with major challenges in the future. The expansion of renewable energy is leading to an ever-increasing proportion of volatile electricity feed from wind and solar energy and thus to increasingly fluctuating electricity prices: Decreasing electricity rates with ample electricity supply, rising rates with low capacities.

Using the best possible conditions at all times and at the same time ensuring a high level of safety in the water supply requires highly intelligent control of pumps and valves. To accomplish this, various data must be taken into account and synchronized in real time: Current consumption patterns, existing assets such as peak or base load pumps, storage capacities and current electricity rates. And all this 24 hours a day, 365 days a year.

Under such circumstances, efficient operation by the operator alone is no longer possible.

SIWA Optim is a decision support system for optimized pump scheduling based on data like security of water supply and demand, energy tariffs, water prices, or pump operational efficiency and availability.
