2. What is Cogeneration?
Process in which electricity and heat are produced at the same time with a single fuel source.
Cogeneration recovers the typically wasted heat that the generator produces and uses it elsewhere in the facility.

3. Uses of Cogeneration
Cogeneration can be used in any facility that uses generators on site.
Facilities that have a constant electrical and thermal need are the ones that benefit the most.
Hospitals
Nursing Homes
Colleges
Government Buildings
Hotels

4. Positives & Negatives of Cogeneration
Lower facility’s energy usage
Environmentally friendly
Negatives:
Costs
Equipment costs
Maintenance costs
Installation costs
System size

5. Future for Cogeneration
The future for cogeneration will continue to grow as more organizations find out just how cost effective the system can be.
Russia is projected to continue to grow and be the highest user of cogeneration of the countries studied for this graph.

6. Conclusion
Cogeneration systems capture the heat that is produced by a generator while it is producing electricity and uses this heat elsewhere in the facility.
Cogeneration systems are a great addition to a facility that wants to save on energy costs and become more environmentally friendly.
