Virginia Administrative Code › Title 20 - PUBLIC UTILITIES AND TELECOMMUNICATIONS › Agency 5 - STATE CORPORATION COMMISSION › Chapter 335 - REGULATIONS GOVERNING THE DEPLOYMENT OF ENERGY STORAGE › Section 20VAC5-335-20 - Definitions

Current through Register Vol. 40, No. 24, July 15, 2024
The following words and terms when used in this chapter shall
				  have the following meanings unless the context clearly indicates
				  otherwise:
"Behind the meter" means any system that is on the customer
				  side of the utility service meter.
"Behind-the-meter incentive" means any incentive that
				  encourages an end-use electric customer to implement energy storage systems
				  that are connected to the customer side of the utility service meter,
				  regardless of who actually owns the energy storage equipment.
"Commission" means the Virginia State Corporation
				  Commission.
"Demand-side management program" means energy efficiency,
				  demand response, or peak shaving programs or pilots approved by the commission
				  that a utility may offer to customers pursuant to §
									56-585.1A
				  5 of the Code of Virginia.
"Energy storage" means any technology that is capable of
				  absorbing energy, storing that energy for a period of time, and re-delivering
				  that energy after storage.
"Energy storage aggregator" means a person or entity that, as
				  an agent or intermediary, (i) offers to purchase or purchases energy storage
				  system capabilities; or (ii) offers to arrange for or arranges for the purchase
				  of energy storage system capabilities for the purposes of combining or
				  aggregating those capabilities to enable the participation of multiple energy
				  storage systems in electricity markets where such individual systems could not
				  participate individually.
"Energy storage capacity" or "stored usable energy" means the
				  maximum amount of stored energy of the energy storage system in kilowatt-hours
				  or megawatt-hours that can be delivered to the grid.
"Energy storage facility" or "energy storage system" means an
				  energy storage resource and any equipment, other than a transmission or
				  distribution line, needed to interconnect the energy storage resource to the
				  utility's electric system. This additional equipment can include switchgear,
				  transformers, inverters, switches, cables, wires, conductors, bus work,
				  protection devices and systems, communication and control devices and systems,
				  fire protection systems, and environmental protection systems. Other costs
				  associated with the construction and operation of an energy storage facility or
				  energy storage system may include property acquisition costs, development and
				  study costs, or other costs necessary to complete an operative facility or
				  system.
"Energy storage power rating" means the total possible
				  instantaneous discharge capability in kilowatts or megawatts of the energy
				  storage system, or the maximum sustained rate of discharge that the energy
				  storage system can achieve starting from a fully charged state to a fully
				  discharged state.
"Energy storage project" means an energy storage facility
				  with a specified location and an associated energy storage capacity and energy
				  storage power rating.
"Energy storage resource" means (i) a resource capable of
				  collecting energy from the electric power grid or a power generation facility
				  and then discharging the energy at a future point in time to provide
				  electricity or other grid services, or (ii) a resource capable of the active or
				  dynamic exchange of energy.
"Non-wires alternative program " means any electricity grid
				  investment, project, or program that uses nontraditional transmission or
				  distribution solutions, such as distributed generation, energy storage, energy
				  efficiency, demand response, and grid software and controls, to delay or remove
				  the need for traditional system upgrades of equipment, such as transmission or
				  distribution lines or transformers, without impacting the safety or overall
				  performance of the electric power system.
"Peak demand reduction program" means any project or program
				  aimed at shifting time of use of electricity from one period to another for the
				  overall economic and reliability benefit of the electric power grid.
"Person" means any individual, corporation, partnership,
				  association, company, business, trust, joint venture, or other private legal
				  entity, and the Commonwealth or any municipality.
"Phase I Utility" has the same meaning as provided in
				  subdivision A 1 of §
									56-585.1
				  of the Code of Virginia.
"Phase II Utility" has the same meaning as provided in
				  subdivision A 1 of §
									56-585.1
				  of the Code of Virginia.
"Storage duration" means the amount of time an energy storage
				  system can discharge at its energy storage power rating before depleting the
				  stored usable energy when the system is at maximum energy storage capacity.
				  Energy storage resources can de-rate their maximum output in order to increase
				  energy storage duration.
