The EU target on energy efficiency implies a 20 % reduction in the use of primary energy by implementation of energy efficiency measures. Not all potential cost-effective measures for improved energy efficiency are implemented. This energy efficiency gap is explained by market barriers. Policy instruments can be used to overcome these barriers. The target could, for example, be obtained through industrial excess heat recovery; but there is a knowledge gap on factors affecting excess heat utilization. In this study, interviews were carried out with energy managers in order to study excess heat utilization from industrys perspective. The study seeks to present how excess heat recovery can be promoted or discouraged through policy instruments, and several factors are raised in the paper. The interviews revealed that excess heat recovery is generally referred to in terms of heat deliveries to the district heating network. One may need to look for innovative recovery solutions, and policies are needed to bring these solutions into action. Due to inefficient conversion for heat-driven electricity generation, a system favoring this implementation could favor an inefficient system. Beyond external instruments, internal goals, visions, and the importance of energy as a priority were shown to be important in the work with improved energy management.
