Cogeneration Plant
The fuel tank for heavy fuel oil
Emissions
When the heating plant is mainly burning heavy fuel oil, the emissions associated with the cogenerated electricity are comparable with those of normal electricity from the grid. When the plant burns a higher percentage of natural gas, the emissions of the cogenerated electricity are significantly lower than those of average grid electricity. At this time, the heating plant is limited in the percentage of natural gas that it can burn.
Cost
Electricity cogenerated at the heating plant is significantly less expensive than electricity purchased from the grid. Cost for purchased electricity is approximately $.13 per kilowatt hour. Cogenerated electricity varies depending on the mix of fuel burned at the heating plant, and on the cost of natural gas and heavy fuel oil, but was approximately $.04 in fiscal year 2005.
