Combined Heat and Power: A Successful Past Meets a Bright Future

摘要

This article presents information related to the author's experience with combined heat and power (CHP) systems. Topics covered include: why and when to evaluate CHP, applications in a Midwestern city and utility policies that effect CHP applications. Studying successful, longstanding CHP applications, examining the benefits the owners received and current equipment/policies is an excellent starting point for evaluating CHP and making a good "case" for new projects. Gas transportation rates and electric curtailment programs are discussed and the concept of a tolling contract for CHP is introduced.
