How the Competition Works
Water utilities can access LEEM and PEPSO during the Trial Period and use both tools in their systems prior to the competition without any obligation or fee.
LEEM (Locational Emission Estimation Methodology)
In 2014, fossil fuel electric generators in the US created 57% of the mercury and 30% of the carbon dioxide emitted to the atmosphere in the U.S. LEEM is a powerful new tool for energy managers to track, control and reduce these emissions including mercury, carbon and other pollutants that result from consumption of electricity. Developed and maintained at WSU, LEEM provides predictive and real-time emission intensity data for mercury, CO2, SO2, NOx, and lead in 18 states, 8 of which are in the Great Lakes Basin; Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, Wisconsin. LEEM may be available on a case by case basis in Ontario.
With LEEM, water utilities can:
- — Track times when electricity is supplied by high-emission generators
- — Control how their energy management systems respond to Peak Emissions periods
- — Reduce electricity usage during Peak Emissions
PEPSO (Pollutant Emission Pump Station Optimization)
PEPSO is a software package that performs optimization of large water distribution systems including cost and environmental emissions objectives. PEPSO optimization is integrated with the LEEM data stream. PEPSO and LEEM are seamlessly coupled for ease of utility operator use.
With PEPSO, water utilities can:
- — Optimize pump operation schedules
- — Reduce pump energy consumption
- — Reduce related pollution emissions while maintaining the required flow and pressure of the water distribution system
