What is Energy Performance Contracting?

It is a set of services for reduction of energy and water use, and reduction of costs for energy and water supply which include: overview of condition of energy devices, analysis of energy use and expenses, preparation of technical solutions for improving current condition, calculation of possible savings and feasibility (economics) of the project, design and planning of measures (from investments required to “soft” measures), implementation of measures, implementation of operation during contractual period, implementation of energy bookkeeping, actions and provisions of effects, agreed with the contract and, most importantly, providing sources of financing for implementation of all services. We use two main business models of contractual financing for implementation of the above stated services:

  • Contractual provision of savings; and
  • Contractual energy supply, but combination of both options also occurs in practice.
