ebXML (Electronic Business XML): sponsored by UN/CEFACT and OASIS, provides a standard method to exchange messages, conduct trading relationships, communicate data in common terms and define and register business processes. The ebXML initiative, started November 1999, is creating a global framework for the exchange of business data using XML across industries and among businesses of all sizes. It uses SOAP for messaging. It was created to replace/upgrade EDI. Competing solution to BizTalk and RosettaNet. More...

An element may be comprised of one or more components. (NERC "Terms and Their Definitions As Used in the NERC Planning Standards")

E-mail Address: The address that identifies an electronic post office box where e-mail messages can be sent. All modern e-mail messages have the form UserName@domainAddress.

E-mail Client: A program that allows you to send and receive e-mail. Popular e-mail clients include Eudora, Microsoft Outlook Express, and Netscape Communicator.

include Eudora, Microsoft Outlook Express, and Netscape Communicator.

Emergency Network Operating Conditions - Operating conditions of the equipment, installations and systems expected by the transmission system operator with an emergency outage of the specific grid elements.

Emoticon: Characters that are meant to be viewed sideways that reflect the emotional state of the writer of the message. Because electronic mail does not allow for body language or other emotional clues, emoticons are very useful. Common emoticons are:

EMS (Energy Management System): used for analyzing the electric power transmission system and for automatic control of generation for load following.

Encoding: A method of converting a message into digital data. Text is character encoded using; e.g., ASCII, cyrillic encoding, or Unicode. Non-text uses UUencode or MIME encoding.

Encryption: The conversion of data into a secret code meant to prevent unauthorized access to confidential information transferred over the Internet or other network. Encryption relies on passwords or code keys for conversion. Popular encryption methods are PGP and SSL. Unencrypted data is called plain text; encrypted data is referred to as cipher text.

End-Use Customer - Customer that consumes in its own ends all the purchased energy.

Energy: The capacity for doing work as measured by the capability of doing work (potential energy) or the conversion of this capability to motion (kinetic energy). Energy has several forms, some of which are easily convertible and can be changed to another form useful for work. Most of the world's convertible energy comes from fossil fuels that are burned to produce heat that is then used as a transfer medium to mechanical or other means in order to accomplish tasks. Electrical energy is usually measured in kilowatthours, while heat energy is usually measured in British thermal units.  [DOE Glossary of Electricity Terms]

Energy Charge: That portion of the charge for electric service based upon the electric energy (kWh) consumed or billed.
 [DOE Glossary of Electricity Terms]

Energy Deliveries: Energy generated by one electric utility system and delivered to another system through one or more transmission lines.
 [DOE Glossary of Electricity Terms]

Energy Efficiency: Refers to programs that are aimed at reducing the energy used by specific end-use devices and systems, typically without affecting the services provided. These programs reduce overall electricity consumption (reported in megawatthours), often without explicit consideration for the timing of program-induced savings. Such savings are generally achieved by substituting technically more advanced equipment to produce the same level of end-use services (e.g. lighting, heating, motor drive) with less electricity. Examples include high-efficiency appliances, efficient lighting programs, high-efficiency heating, ventilating and air conditioning (HVAC) systems or control modifications, efficient building design, advanced electric motor drives, and heat recovery systems.
 [DOE Glossary of Electricity Terms]

Energy Receipts: Energy generated by one electric utility system and received by another system through one or more transmission lines.
 [DOE Glossary of Electricity Terms]

Energy Source: The primary source that provides the power that is converted to electricity through chemical, mechanical, or other means. Energy sources include coal, petroleum and petroleum products, gas, water, uranium, wind, sunlight, geothermal, and other sources.
 [DOE Glossary of Electricity Terms]
