EDTF: Environmental Data Task Force - A task force created by the SPSG to develop recommendations
on the type, quality, and sources of data on wild lands, wildlife, cultural resources and potential water
resources that can be used in transmission planning processes.
EE: Energy Efficiency - Programs and policies designed to reduce electric energy consumption or
increase the efficiency of electric loads.
Electric Demand - The rate at which energy is being used by the customer, expressed in kilowatts,
megawatts, or gigawatts.
Electric Energy - The generation or use of electric power by a device over a period of time, expressed in
kilowatthours (kWh), megawatthours (MWh), or gigawatthours (GWh).
Electric Load - An end-use device or customer that receives power from the electric system.
FERC: Federal Energy Regulatory Commission - An independent federal agency that regulates the
interstate transmission of natural gas, oil, and electricity. FERC also regulates natural gas and
hydropower projects.
Generation - The process of producing electricity by transforming other forms or sources of energy into
electrical energy; measured in kilowatt-hours.
Generation Fuel Types - Coal, natural gas, hydro, solar (thermal and photovoltaic), wind, and
geothermal.
HWG: Historical Work Group - The HWG analyzes historical transmission line (path) flows, schedules,
and availability.
IC: Internal Combustion Engine - The generation of electric power by a heat engine which converts part
of the heat generated by combustion of the fuel into mechanical motion to operate an electric
generator.
IRP: Integrated Resource Plan - A plan developed by an electric power provider, sometimes as required
by a public regulatory commission or agency, that defines the short and long term capacity additions
(supply side) and demand side management programs that it will undertake to meet projected energy
demands.
Load Center - A geographic area with a concentrated electrical load.
LSE: Load-Serving Entity - Secures energy and transmission service (and related Interconnected
Operations Services) to serve the electrical demand and energy requirements of its end-use customers.
Mgd - Millions of gallons per day.
MW: Megawatt - One thousand kilowatts, or 1 million watts; standard measure of electric power plant
generating capacity.
