((1)) ** Administrator** The term “Administrator” means the Administrator of the Environmental Protection Agency.

((2)) ** Combined heat and power** The term “combined heat and power system” means a facility that—

((A)) simultaneously and efficiently produces useful thermal energy and electricity; and

((B)) recovers not less than 60 percent of the energy value in the fuel (on a higher-heating-value basis) in the form of useful thermal energy and electricity.

((3)) ** Net excess power** The term “net excess power” means, for any facility, recoverable waste energy recovered in the form of electricity in quantities exceeding the total consumption of electricity at the specific time of generation on the site at which the facility is located.

((4)) ** Project** The term “project” means a recoverable waste energy project or a combined heat and power system project.

((5)) ** Recoverable waste energy** The term “recoverable waste energy” means waste energy from which electricity or useful thermal energy may be recovered through modification of an existing facility or addition of a new facility.

((6)) ** Registry** The term “Registry” means the Registry of Recoverable Waste Energy Sources established under .section 6342(d) of this title

((7)) ** Useful thermal energy** The term “useful thermal energy” means energy—

((A)) in the form of direct heat, steam, hot water, or other thermal form that is used in production and beneficial measures for heating, cooling, humidity control, process use, or other valid thermal end-use energy requirements; and

((B)) for which fuel or electricity would otherwise be consumed.

((8)) ** Waste energy** The term “waste energy” means—

((A)) exhaust heat or flared gas from any industrial process;

((B)) waste gas or industrial tail gas that would otherwise be flared, incinerated, or vented;

((C)) a pressure drop in any gas, excluding any pressure drop to a condenser that subsequently vents the resulting heat; and

((D)) such other forms of waste energy as the Administrator may determine.

((9)) ** Other terms** The terms “electric utility”, “nonregulated electric utility”, “State regulated electric utility”, and other terms have the meanings given those terms in title I of the Public Utility Regulatory Policies Act of 1978 ( et seq.).16 U.S.C. 2611
