from the surrounding area.
The new cogeneration process will clean and utilize all of the methane gas burned on-site and use it, thus reducing the need for flares. Some gas will be used in existing boilers and heaters, and the rest will run the generators that produce electricity. This process will reduce the city's purchase of electrical power by $1.4 million annually and effectively utilize the methane gas produced at Back River.
The savings resulting from reducing the amount of electricity purchased was sufficient to pay for the capital cost of the new facilities and other benefits including:
• Annual reduction of 19.4 million kWh of electricity in plant operations.
• $14 million in energy savings and plant improvement projects over ten years.
• Annual reduction of 12.9 million pounds of carbon monoxide and 7.7 grams of nitrogen oxide.
The following is a description of a unique process used to develop, implement, and finance the project.
