Benefits of Combined Heat and Power
- Energy savingsPower qualityReliabilityIndependence
- Reduced air emissions
Reliability
- Reduced impact of potential electrical grid power loss (local or regional)Backed up by the existing emergency diesel generatorsBacked up by the utility grid during maintenance shutdowns and unplanned outage periods
- Backed up by the existing steam boiler plant
- Reduced Emissions
- Reduce emissions for NOx, CO, SO2, VOCs, PM, and other Green House Gases as compared to the existing combination of the Electric Power Plants and EMMC’s steam plant
