Common Electricity Definitions - Learn the Electrical Lingo

Updated: Aug 27

Every industry has specific jargon and terms that are supposed make communications easier. Not only do some of these confuse regular customers, they also confuse industry professionals as the same thing is called different names by different people. See our list of common industry terms below:

  • ICI – Industrial Conservation Initiative – The program from the government that allows larger energy consumers to achieve cost savings. (NOT Industrial Commercial Institutional)

  • Class A – Electricity consumers who are eligible to participate in ICI, must be above 1MW average monthly peak demand OR above 500kW and in NAICS sector "31", "32", "33" or “1114”.

  • Class B – Any consumer who is not Class A. i.e. houses, small industrial, commercial.

  • Global Adjustment – Monthly Charge for energy, charged differently depending on Class A or B, usually shortened to GA. It reflects the difference between the wholesale market price of electricity and the regulated rates for OPG nuclear and hydroelectric generating stations. It also covers the difference between the market price and the contracted rates payed to generators across the province.

  • pTrack Edgecom Energy's solution for planning and managing the ICI program in order to maximize electricity savings.

  • Base Period - The base setting period is the period during the ICI cycle in which the customer's status as Class A is set AND the period in which the customer's peak demand factor is defined.

  • Adjustment Period - The period during the ICI cycle in which the GA is charged. The actions taken during the previous base period are not reflected until the afjusment period (July 1 of each year).

  • IESO – Independent Electricity System Operator, operate the Ontario electricity grid. (Use to be called OPA)

  • LDC – Local Distribution Company, they run the local electricity grid and usually deliver the power to your home or business. They usually send you the power bill. TorontoHydro, Alectra, Wellington North Power Inc, London Hydro Inc are all examples of LDCs.

  • Coincident Peak or "Peak Day" - Coincident demand is the energy demand required by a given customer or class of customers during a particular time period. Coincident peak demand is the energy demand by that group during periods of peak system demand.

  • Curtailment – Reduction in electricity use for a short period of time. Usually 3 to 4 hours for the purposes of the ICI program.

  • Energy Retrofit - Energy retrofits are upgrades to a building’s energy-consuming systems. They can involve measures ranging from superficial, low-cost measures/modifications to full overhauls or replacement of major systems.
