Current through July 10, 2024
(a)
Definitions.
For purposes of this section, the following
			 definitions shall apply:
"Certification" means documentation that a distributed
				generator will comply with the applicable emissions standards and certification
				requirements of this section when installed as supplied and operated and
				maintained according to the manufacturer's instructions.
"Certifying entity" means a person issuing a certification that
				satisfies the requirements of subsection (e) of this section.
"Combined heat and power system" or "CHP system" means a
				distributed generator that sequentially produces both electric power and
				thermal energy from a single source.
"Design system efficiency" means, for a CHP system, the sum of
				the full load design thermal output and electric output divided by the heat
				input.
"Distributed generator" means any new or existing generator
				with a nameplate capacity less than 15 MW that generates electricity for other
				than emergency use. Electricity generated may be used either on-site or for
				sale under an agreement with a utility, other market participant or system
				operator. Such a generator may also generate electricity for use during an
				emergency but is not defined as an emergency generator. Such a generator may
				burn two fuels simultaneously but is not defined as a dual-fuel
				generator.
"Dual-fuel generator" means a distributed generator that has
				the capacity to be fired by either a gaseous fuel, or a liquid fuel, such as
				diesel or No. 2 grade oil, but not by both a gaseous fuel and a liquid fuel
				simultaneously.
"Effective date" means the date on which this section is
				adopted in accordance with the provisions of chapter 54 of the Connecticut
				General Statutes.
"Emergency" means "emergency" as defined in section
				22a-174-22 e(a) of the
				Regulations of Connecticut State Agencies.
"Emergency generator" means "emergency engine" as defined in
				section
				22a-174-22 e(a) of the
				Regulations of Connecticut State Agencies.
"Existing" means, for a generator, installed prior to the
				effective date of this section.
"Flared fuel" means gases that are emitted directly into the
				ambient air or burned without generating electricity or useful mechanical or
				thermal energy.
"Gaseous fuel" means natural gas and other fossil fuels that
				are in a gaseous state when used to fuel a generator.
"Generator" means any equipment that converts primary fuel,
				including fossil fuel and renewable fuel, into electricity or electricity and
				thermal energy.
"Installed" means the date on which a generator is first
				capable of generating electricity.
"ISO" means the International Organization for
				Standardization.
"Motor vehicle diesel fuel" means on-road diesel fuel that
				meets sulfur limits in
				40 CFR
				80.29,
				80.500(a)
				and
				80.520(a)
				and (b).
"New" means, for a generator, installed on or after the
				effective date of this section.
"Power-to-heat ratio" means, for a CHP system, the design
				electrical output divided by the design recovered thermal output, where both
				outputs are measured in consistent units.
"Reciprocating engine" means a stationary internal combustion
				engine having a crankshaft turned by linearly reciprocating pistons.
"Supplier" means a person who manufactures, assembles or
				otherwise makes distributed generators available to owners and
				operators.
"System operator" means a person responsible for managing a
				geographical region's electric bulk power generation and transmission
				systems.
(b)
Applicability and exemptions.
(1)
			 The owner or operator of a distributed generator may operate such generator
			 without obtaining a new source review general permit for such generator or a
			 permit issued pursuant to section
			 22a-174-3 a of the
			 Regulations of Connecticut State Agencies if:
(A) The generator is an emission unit with
			 potential emissions of fifteen (15) tons or more per year of an individual air
			 pollutant;
(B) The generator is not
			 a new major stationary source;
(C)
			 The generator is not a newly constructed or reconstructed major source of
			 hazardous air pollutants subject to the requirements of section
			 22a-174-3 a(m) of the
			 Regulations of Connecticut State Agencies;
(D) In any calendar year, the generator is
			 operated no more than the number of hours determined from the following
			 equation; and
