Energy performance contracts (EPC) are important tools to spread energy efficiency (EE) applications in the energy service market of countries, encourage large-scale projects by overcoming the risk on the customer side, and provide financing on the projects implemented by energy service companies. This study aims to analyze the level of market participant knowledge, present the experiences of EE projects with and without the utilization of EPCs, evaluate the main market barriers, and draw policy recommendations for the expansion of the market in Turkey. For this purpose, an online survey was conducted on energy service company representatives, facility workers, and independent energy managers. The Chi-Square χ2 test, which is preferred in the analysis of non-parametric and qualitative data, was used in the statistical evaluation of the answers. Survey results show that there are no significant associations observed between projects with and without using EPC. Results show that EPC applications in Turkey do not meet certain EPC requirements. The study revealed that obtaining financing is the most difficult stage for both projects. For the correct and widespread implementation of EPCs in Turkey, there is still a need for more development including improving sector coverage, stakeholders' knowledge, and market conditions.
