This report provides guidelines on how thermal electricity generation installations and industrial installations can carry out a Cost-Benefit Analysis (CBA) in order to assess whether the use of high-efficiency cogeneration, the connection to a district heating or cooling network or other means of waste heat recovery would be cost-effective. More specifically the guidelines include: (1) all concepts and methods available for the identification of necessary elements for performing a CBA following Part 2 of Annex IX  of EED for individual installations, (2) generic informal guidance and case specific instructions on how to apply the described methodology for the various cases described, (3) similarities and differences of this study with the Comprehensive Asessment and (4) how the Comprehensive Assessment could establish exemptions for installations from the CBA obligation.

Three best practice guidelines have been prepared by JRC on how to: (1) assess the economic energy efficiency efficient potential at the national level, (2) perform installation level assessments, and (3) heat maps, following the requirements of the Energy Efficiency Directive (EED) Article 14.
