Guaranteed Energy Savings Contract (GESC)

A Guaranteed Energy Savings Contract (GESC) is an agreement between a qualified provider and a building owner to reduce the energy and operating costs of a building or a group of buildings by a specified amount. Indiana Code 36-1-12.5 stipulates which governing bodies are able to enter into a GESC. This list is exclusive to what is defined by IC 36-1-12.5: schools, libraries, municipal water or wastewater utilities operated by a political subdivision, and other governing bodies.

As schools and other governing bodies consider building new facilities or improving existing facilities, making energy efficiency a central part of the planning process has become more important than ever as energy costs rise and budgets decline. By utilizing GESCs, schools and governing bodies in Indiana can benefit from the economic and performance benefits from increased energy efficiency. The main advantage of these agreements is that the building owner can participate in the project without a large upfront investment of capital. The savings are used to pay for the investment over a period not to exceed the lesser of 20 years or the payback period of the project. If the guaranteed savings are not achieved, the provider must reimburse the building owner for the difference between the guaranteed savings and actual cost savings.

The governing body must also report the savings resulting from the contract annually to the DLGF for the life of the contract, which can be and is accomplished by submitting a completed Annual Savings Report. This can be done by email or mail. The report is to be emailed or mailed to the DLGF no later than sixty (60) days after the end of each year the savings guarantee is in force.
