ESCO

An ESCO( Energy Service Company Or Energy Saving Company) is a company that offers energy services which may include implementing energy-efficiency projects (and also renewable energy projects) and in many case on a turn-key basis. The three main characteristics of an ESCO are:

  • ESCOs guarantee energy savings and/or provision of the same level of energy service at lower cost. A performance guarantee can take several forms. It can revolve around the actual flow of energy savings from a project, can stipulate that the energy savings will be sufficient to repay monthly debt service costs, or that the same level of energy service is provided for less money.
  • The remuneration of ESCOs is directly tied to the energy savings achieved;
  • ESCOs can finance, or assist in arranging financing for the operation of an energy system by providing a savings guarantee.

 

Energy services include a wide range of activities, such as:

  • energy analysis and audits,
  • energy management,
  • project design and implementation,
  • maintenance and operation,
  • monitoring and evaluation of savings,
  • property/facility management,
  • energy and/or equipment supply,
  • provision of service (space heating, lighting, etc.)
