Challenges in Modeling CHP Modeling the operations of combined heat and power generators in a production simulation setting is challenging for several reasons: 1.Thermal Load Service: CHP operations are often dictated by the size of the thermal load, so their responsiveness to wholesale market conditions are limited 2.On-Site Electric Use: Many CHP plants are located on-site at industrial facilities, and their generation is split between on-site use (behind-the-meter) and exports to the grid There is no single rule of thumb that accurately predicts the hourly operations of plants that are operated for cogeneration 7
