In this subtitle: The term combined heat and power system means generation of electric energy and heat in a single, integrated system that meets the efficiency criteria in clauses
(ii)and
(iii)of section 48(c)(3)(A) of the Internal Revenue Code of 1986, under which heat that is conventionally rejected is recovered and used to meet thermal energy requirements. The term demand response means changes in electric usage by electric utility customers from the normal consumption patterns of the customers in response to— changes in the price of electricity over time; or incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized. The term distributed energy means energy sources and systems that— produce electric or thermal energy close to the point of use using renewable energy resources or waste thermal energy; generate electricity using a combined heat and power system; distribute electricity in microgrids; store electric or thermal energy; or distribute thermal energy or transfer thermal energy to building heating and cooling systems through a district energy system. The term district energy system means a system that provides thermal energy to buildings and other energy consumers from 1 or more plants to individual buildings to provide space heating, air conditioning, domestic hot water, industrial process energy, and other end uses. The term islanding means a distributed generator or energy storage device continuing to power a location in the absence of electric power from the primary source. The term loan has the meaning given the term direct loan in section 502 of the Federal Credit Reform Act of 1990 ( 2 U.S.C. 661a ). The term microgrid means an integrated energy system consisting of interconnected loads and distributed energy resources, including generators and energy storage devices, within clearly defined electrical boundaries that— acts as a single controllable entity with respect to the grid; and can connect and disconnect from the grid to operate in both grid-connected mode and island mode. The term renewable energy source includes— biomass; geothermal energy; hydropower; landfill gas; municipal solid waste; ocean (including tidal, wave, current, and thermal) energy; organic waste; photosynthetic processes; photovoltaic energy; solar energy; and wind. The term renewable thermal energy means heating or cooling energy derived from a renewable energy resource. The term thermal energy means— heating energy in the form of hot water or steam that is used to provide space heating, domestic hot water, or process heat; or cooling energy in the form of chilled water, ice, or other media that is used to provide air conditioning, or process cooling. The term waste thermal energy means energy that— is contained in— exhaust gases, exhaust steam, condenser water, jacket cooling heat, or lubricating oil in power generation systems; exhaust heat, hot liquids, or flared gas from any industrial process; waste gas or industrial tail gas that would otherwise be flared, incinerated, or vented; a pressure drop in any gas, excluding any pressure drop to a condenser that subsequently vents the resulting heat; condenser water from chilled water or refrigeration plants; or any other form of waste energy, as determined by the Secretary; and in the case of an existing facility, is not being used; or in the case of a new facility, is not conventionally used in comparable systems.
