Glossary of Terms
Transmission and Distribution.
Term used by regulatory agency to describe an electric transmission system wire owner.
Charges related to the provision of transmission access services to retailers, regulated rate providers and direct connect consumers and recovered from the AESO.
Trading Practices Guidelines.
Electricity flows from the generators through the wires to consumers. Wires have a small level of resistance that works against the flow of the electric current. The grid consumes a small amount of the power in overcoming this resistance and the power consumed in this way is referred to as losses. (AESO web site definition)
The committee accountable to the AESO with membership made up of transmission facility owners, charged with the on-going review and upgrading of all operating standards and guidelines for coordinated operation of the transmission system.
The wires and other facilities for the transportation of electric energy at greater than 25,000 volts and generally over longer distances. (also Transmission Facility)
A turbine converts the mechanical energy inherent in the linear flow of a fluid (liquid or gas) to rotational mechanical energy that, if coupled to an electric generator, can be used to produce electric energy. Sometimes the coupling of a turbine to an electric generator is done through a direct shaft, but often, especially in the case of modern wind turbines, it is done through a gearbox.
