efficiency no less than the PURPA requirements. These issues are more related to site-
specific application, design, and proper sizing of equipment than to CHP equipment
itself but none the less is a critical element in the future success of CHP.
Capital cost continues to be a significant barrier for wide implementation of CHP.
Future CHP systems need to target this area with modular power generation and
thermal designs being developed to reduce installed costs as well as increase integra-
tion reliability. Acceptable monitoring and data logging equipment will also be required
to meet reporting requirements as more incentive programs move toward verifiable
production type payments.
Environmental concerns and greenhouse gas emission reduction targets will
continue to be a strong motivation for policy makers to support CHP deployment. CHP
systems must continue to reduce emissions levels and in many cases will require the
addition of exhaust after treatment equipment to show significant gains over conven-
tional technology.
