As an example, for a typical cement plant producing 5,000 tons per day, a waste heat recovery system can reliably supply about a third of the plant's power needs. Based on an average electric grid price of 0.12 USD/kWh and a cost of operating a cogeneration unit at 0.01 USD/kWh, the plant stands to save a massive USD 6 million a year.
