Sec. 222.2. Definitions

(a) The definitions of Part 200 and Subpart 201-2 of this Title apply to this Part unless they are inconsistent with the definitions in subdivision (b) of this section.

(b) The following definitions also apply to this Part:

(1) Compression ignition. A type of stationary internal combustion engine that is not a spark ignition engine.

(2) Demand response program. The Emergency Demand Response Program or Special Case Resources demand response programs sponsored by the New York Independent System Operator or similarly designed programs sponsored by distribution utilities and approved by the Public Service Commission.

(3) Demand response source. A distributed generation source enrolled in a demand response program.

(4) Demand response event. Activation of a demand response program by the New York Independent System Operator or a distribution utility.

(5) Distribution utility. A retail distributor of electricity.

(6) Distributed generation source. A stationary reciprocating or rotary internal combustion engine that feeds into the distribution grid or produces electricity for use at the host facility or both. This includes, but is not limited to, emergency power generating stationary internal combustion engines and demand response sources.

(7) Economic dispatch source. A distributed generation source intended to provide electricity for general use to a building, structure, or collection of structures in place of electricity supplied by the distribution utilities. Demand response and price-responsive generation sources are considered economic dispatch sources. Economic dispatch sources do not include emergency generators or distributed generation sources that provide electricity to power equipment or structures not served by distribution utilities.

(8) Lean burn engine. A natural gas-fired spark ignition engine that is not a rich burn engine.

(9) Maximum load relief. Maximum power (kilowatts) pledged by a demand response source during demand response events or the maximum load the source operates at as a price-responsive generation source.

(10) Model year. Means either:

(i) the calendar year in which the engine was originally produced; or

(ii) the annual new model production period of the engine manufacturer if it is different than the calendar year. This must include January 1st of the calendar year for which the model year is named. It may not begin before January 2nd of the previous calendar year and it must end by December 31st of the named calendar year.

(11) Price-responsive generation source. A distributed generation source used to provide electricity for short periods of time when the cost of electricity supplied by the distribution utility is high.

(12) Rich burn engine. Any four-stroke spark ignited engine where the manufacturer’s recommended operating air-to-fuel ratio divided by the stoichiometric air-to-fuel ratio at full load conditions is less than or equal to 1:1.

(13) Spark ignition. A natural gas fueled engine or any other type of engine with a spark plug (or other sparking device) and with operating characteristics similar to the theoretical Otto combustion cycle. Dual-fuel engines in which a liquid fuel (typically diesel fuel) is used for compression ignition and gaseous fuel (typically natural gas) is used as the primary fuel at an annual average ratio of less than 2 parts diesel fuel to 100 parts total fuel on an energy equivalent basis are spark ignition engines.

(14) Three-way catalyst emission controls. A control technology (also known as non-selective catalytic reduction) that reduces NO_x, volatile organic compounds and carbon monoxide emissions from rich burn engines.
