  • East Central Area Reliability Coordination Agreeme : One of the ten regional reliability councils that make up the North American Electric Reliability Council (NERC).
  • Economic Dispatch : The distribution of total generation requirements among alternative sources for optimum system economy with consideration to both incremental generating costs and incremental transmission losses.
  • Economic Efficiency : A term that refers to the optimal production and consumption of goods and services. This generally occurs when prices of products and services reflect their marginal costs. Economic efficiency gains can be achieved through cost reduction, but it is better to think of the concept as actions that promote an increase in overall net value (which includes, but is not limited to, cost reductions).
  • Economy Energy : Energy produced and substituted for the traditional but less economical source of energy. Economic energy is usually sold without capacity and is priced at variable costs plus administration costs.
  • Efficiency Service Company : A company that offers to reduce a client's electricity consumption with the cost savings being split with the client.
  • Elasticity of Demand : The ratio of the percentage change in the quantity demanded of a good to the percentage change in price.
  • Electric Capacity : This refers to the ability of a power plant to produce a given output of electric energy at an instant in time, measured in kilowatts or megawatts (1,000 kilowatts).
  • Electric Distribution Company : The company that owns the power lines and equipment necessary to deliver purchased electricity to the customer.
  • Electric Plant (Physical) : A facility that contains all necessary equipment for converting energy into electricity.
  • Electric Power Supplier : Non-utility provider of electricity to a competitive marketplace.
  • Electric Rate Schedule : An electric rate and its contract terms accepted by a regulatory agency.
  • Electric Reliability Council of Texas (ERCOT) : One of the ten regional reliability councils that make up the North American Electric Reliability Council (NERC).
  • Electric System : This term refers to all of the elements needed to distribute electrical power. It includes overhead and underground lines, poles, transformers, and other equipment.
  • Electric Utility : A legal entity that owns and/or operates facilities for the generation, transmission, distribution, or sale of electric energy.
  • Electric Utility Affiliate : This refers to a subsidiary or affiliate of an electric utility. Many utilities form affiliates to develop, own, and operate independent power facilities.
  • Electric Wholesale Generator : A power producer who sells power at cost to a customer.
  • Embedded Cost : A utility's average cost of doing business, which includes the costs of fuel, personnel, plants, poles, and wires.
  • End-Use : The specific purpose for which electric is consumed (I.e. heating, cooling, cooking, etc.).
  • Energy : This is broadly defined as the capability of doing work. In the electric power industry, energy is more narrowly defined as electricity supplied over time, express in kilowatt-hours.
  • Energy Charge : The amount of money owed by an electric customer for kilowatt-hours consumed.
  • Energy Consumption : The amount of energy consumed in the form in which it is acquired by the user. The term excludes electrical generation and distribution losses.
  • Energy Costs : Costs, such as for fuel, that are related to and vary with energy production or consumption.
  • Energy Deliveries : Energy generated by one system delivered to another system.
  • Energy Effects : Changes at the consumer meter that reflect activities undertaken in response to utility-administered programs.
  • Energy Efficiency : Programs that reduce consumption.
  • Energy Policy Act of 1992 : This act which was the first comprehensive federal energy law promulgated in more than a decade will help create a more competitive U.S. electric power marketplace by removing barriers to competition. By doing so, this act allows a broad spectrum of independent energy producers to compete in wholesale electric power markets. The act also made significant changes in the way power transmission grids are regulated. Specifically, the law gives the Federal Energy Regulatory Commission the authority to order electric utilities to provide access to their transmission facilities to other power suppliers.
  • Energy Receipts : Energy generated by one utility system that is received by another through transmission lines.
  • Energy Reserves : The portion of total energy resources that is known and can be recovered with presently available technology at an affordable cost.
  • Energy Resources : Everything that could be used by society as a source of energy.
  • Energy Services Companies (ESCOs) : ESCOs would be created in a deregulated, openly competitive electric marketplace. The Energy Services industry would be made up of power aggregators, power marketers and brokers, whose job is to match buyers and sellers, tailor both physical and financial instruments to suit the needs of particular customers, and to allow even the smallest residential customers to form buying groups or cooperatives that will give them the same bargaining power as large industrial customers.
  • Energy Source : A source that provides the power to be converted to electricity.
  • Energy Use : Energy consumed during a specified time period for a specific purpose (usually expressed in kWh).
  • Entitlement : Electric energy or generating capacity that a utility has a right to access under power exchange or sales agreements.
  • Entrance Cable/Service Entrance Conductor : This is the cable running down the side of a customer's house into the meter. This cable is owned by the customer and its maintenance is the customer's responsibility. Work on this cable should be performed only by a licensed electrician.
  • Environmental Attributes : Environmental attributes quantity the impact of various options on the environment. These attributes include particulate emissions, SO2 or Nox, and thermal discharge (air and water).
  • Escape Provision : A contract provision which allows a party, such as an electric customer, to get out of it. Usually, there is a penalty.
  • Exempt Wholesale Generator (EWG) : An EWG is a category of power producer defined by the Energy Policy Act of 1992. EWG's are independent power facilities that generate electricity for sale in wholesale power markets at market-based rates. The Federal Energy Regulatory Commission is responsible for determining EWG status.
