(A - E) (F - J) (K - O) (P - T) (U - Z)

  • 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.
  • Firm Transmission Service : Service that is reserved for at least one year.
  • Fixed Costs : The annual costs associated with the ownership of property such as depreciation, taxes, insurance, and the cost of capital.
  • Flat Rate : A fixed charge for goods and services that does not vary with changes in the amount used, volume consumed, or units purchased.
  • Flexible Load Shape : The ability to modify your utility's load shape on short notice. When resources are insufficient to meet load requirements, load shifting or peak clipping may be appropriate.
  • Flexible Retail PoolCo : This provides a model for the restructured electric industry that features an Independent System Operator (ISO) operating in parallel with a commercial Power Exchange, which allows end-use customers to buy from a spot market or "pool" or to contract directly with a particular supplier.
  • Forced Outage : An outage that results from emergency conditions and requires a component to be taken out of service automatically or as soon as switching operations can be performed. 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 Escalation : The annual rate of increase of the cost of fuel, including inflation and real escalation, resulting from resource depletion, increased demand, etc.
  • 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.
