✦ Main types of EPC ✦
(1) Guaranteed Saving
◉ The client assumes the entire investment required.
◉ ESCO create an EPC contract between the beneficiary and the provider of an energy efficiency improvement measure (ESCO)
◉ The ESCO shall ensure real savings and if they are not enough to cover debt service, then ESCO might pay the difference
◉ If however, the savings exceed the guaranteed level, then the customer must pay an agreed upon percentage of the savings to the ESCO
◉ This mechanism is typically used when the investment associated with the project is undertaken by the customer. This is why this type of contract is only suited for clients with sufficient financing.
(2) Shared Saving
◉ The investment is assumed entirely by the ESCO, including investment financing, management and control of energy consumption.
◉ Attractive for the ESCO as long as it excludes penalties in the event that the implemented measures perform poorly or the initial estimation proves to be too low
◉ In return for providing financing, the ESCO undertakes comprehensive management. In order to compensate for the managerial complexity involved, the ESCO typically prefers large or medium-sized customers.
