  • Facility : A location where electric energy is generated from energy sources.
  • Feasibility Factor : A factor used to adjust potential energy savings to account for cases where it is impractical to install new equipment. For example, certain types of fluorescent lighting require room temperature conditions. They are not feasible for outdoor or unheated space applications. Some commercial applications, such as color-coded warehouses, require good color rendition, so color distortions could also make certain types of lighting infeasible. The feasibility factor equals 100 percent minus the percent of infeasible applications.
  • Federal Energy Regulatory Commission (FERC) : The regulatory agency, in the U.S. Department of Energy, that has jurisdiction over interstate electricity sales, wholesale rates, licensing, etc.
  • Federal Power Act : An act that includes the regulation of interstate transmission of electrical energy and rates. This act is administered by the Federal Energy Regulatory Commission.
  • Feeder : This is an electrical supply line, either overhead or underground, which runs from the substation, through various paths, ending with the transformers. It is a distribution circuit, usually less than 69,000 volts, which carries power from the substation.
  • Feeder Lockout : This happens when a main circuit is interrupted at the substation by automatic protective devices and cannot be restored until crews investigate. This indicates a serious problem on the circuit, usually equipment failure or a broken conductor.
  • Financial Attributes : Financial attributes measure the financial health of the company. Utility management, security analysts, investors, and regulators use these attributes to evaluate a utility's performance against its historic records and industry averages. Key financial attributes include capital requirements, earnings per share of common equity, capitalization ratios, and interest coverage ratios.
  • Firm Energy : Power or power-producing capacity covered by a commitment to be available at all times during the period.

The forced outage can be caused by improper operation of equipment or by human error. If it is possible to defer the outage, the outage becomes a scheduled outage.
  • Franchise Area : This is the territory in which a utility system supplies service to customers.
  • Franchise Monopoly : Under this system, a utility has the right to be the sole or principal supplier of electric power at a retail level in a specific region or area knows as the franchise service territory. In return for its sole supplier privilege, the utility has an obligation to serve anyone who requests service, and agrees to be accountable to state and/or federal regulatory bodies that regulate the utility's performance, accounting procedures, pricing structures, and plant planning and siting.
  • Fuel : A substance that can be burned to product heat.
  • Fuel Adjustment : A clause in the rate schedule that provides for adjustment of the amount of a bill as the cost of fuel varies from a specified base amount per unit. The specified base amount is determined when rates are approved. This item is shown on all customer bills and indicates the current rate for any adjustment in the cost of fuel used by the company. It can be a credit or a debit. The fuel adjustment lags two months behind the actual price of the fuel. For example, the cost of oil in January will be reflected in March's fuel adjustment.
  • Fuel Cell : An advanced energy conversion device that converts fuels to power very efficiently and with minimal environmental impact.
  • Fuel Diversity : A utility or power supplier that has power stations using several different types of fuel. Avoiding over-reliance on one fuel helps avoid the risk of supply interruption and price spikes.

  • Fuel Expenses : Costs associated with the generation of electricity.
  • Fuel-Use Attributes : Fuel-use attributes are important to utilities concerned about reliance on a single fuel or reduction in usage of a particular fuel. These attributes include annual fuel consumption by type and percent energy generation by fuel.
  • Full-Forced Outage : Net capability of generating units unavailable for load for emergencies.
  • Functional Unbundling : The functional separation of generation, transmission, and distribution transactions within a vertically integrated utility without selling of "spinning off" these functions into separate companies.

  • Generating Unit : Combination of connected prime movers that produce electric power.
  • Generation (Electricity) : Process of producing electric energy by transforming other forms of energy.
  • Generation Charges : Part of the basic service charges on every customer's bill for producing electricity. Generation service is competitively priced and is not regulated by Public Utility Commissions. This charge depends on the terms of service between the customer and the supplier.
  • Generation Company (Genco) : A regulated or non-regulated entity (depending upon the industry structure) that operates and maintains existing generating plants. The Genco may own the generation plants or interact with the short term market on behalf of plant owners. In the context of restructuring the market for electricity, Genco is sometimes used to describe a specialized "marketer" for the generating plants formerly owned by a vertically-integrated utility.
  • Generation Dispatch and Control : Aggregation and dispatching (sending off to some location) generation from various generating facilities, providing backup and reliability services.
  • Generator : Machine used to convert mechanical energy into electrical energy.
  • Geothermal : An electric generating station in which steam tapped from the earth drives a turbine-generator, generating electricity.
  • Gigawatt : This is a unit of electric power equal to one billion watts, or one thousand megawatts - enough power to supply the needs of a medium-sized city.
  • Good Utility Practice : Methods and practices that are approved by a significant portion of the industry.
  • Greenfield Plant : This refers to a new electric power generating facility built from the ground up.
  • Grid : Matrix of an electrical distribution system.
  • Gross Generation : Amount of electric energy produced by generating units as measured at the generator terminals.

  • High Heat Value (HHV) : The high or gross heat content of the fuel with the heat of vaporization included; the water vapor is assumed to be in a liquid state.
  • Hourly Metering : Tracking or recording a customer's consumption during specific periods of time that can be tied to the price of energy.
  • Hourly Non-Firm Transmission Service : Transmission scheduled and paid for on an as-available basis and subject to interruption.
  • Hydroelectric : An electric generating station in which a water wheel is driven by falling water, thus generating electricity.
  • Incentive : A rebate or some form of payment used to encourage people to implement a given demand-side management (DSM) technology. The incentive is calculated as the amount of the technology costs that must be paid by the utility for the participant test to equal one and achieve the desired benefit/cost ratio to drive the market.
  • Incremental Effects : Annual effects in energy use and peak load caused by new participants in existing DSM programs and all participants in new DSM programs during a given year.
  • Independent Power Producers (IPPs) : These are private entrepreneurs who develop, own or operate electric power plants fueled by alternative energy sources such as biomass, cogeneration, small hydro, waste-energy and wind facilities.

  • Interchange (Electric utility) : The agreement among interconnected utilities under which they buy, sell and exchange power among themselves. This can, for example, provide for economy energy and emergency power supplies.
  • Interconnection (Electric utility) : The linkage of transmission lines between two utility, enabling power to be moved in either direction. Interconnections allow the utilities to help contain costs while enhancing system reliability.
  • Interdepartmental Service (Electric) : Amounts charged by the electric department at specified rates for electricity supplied by other utility departments.
  • Intermediate Load (Electric Systems) : Range from base load to a point between that and peak load.
  • Intermittent Resources : Resources whose output depends on some other factory that cannot be controlled by the utility e.g. wind or sun. Thus, the capacity varies by day and by hour.
  • Interruptible Loads : Loads that can be interrupted in the event of capacity or energy deficiencies on the supplying system.
  • Interruptible Power : This refers to power whose delivery can be curtailed by the supplier, usually under some sort of agreement by the parties involved.
  • Interruptible Rates : These provide power at a lower rate to large industrial and commercial customers who agree to reduce their electricity use in times of peak demand.
  • Interval Metering : The process by which power consumption is measured at regular intervals in order that specific load usage for a set period of time can be determined.
