Thermal Resistance (R-Value) – The resistance of a material to heat conduction. The higher the R-value, the greater the energy efficiency and the higher resistance to heat transfer.

Transmission – The movement or transfer of electric energy over an interconnected group of lines and associated equipment between points of supply and points at which it is transformed for delivery to consumers, or is delivered to other electric systems. Transmission is a factor in energy efficiency due to the loss of electricity transmitted over longer distances. Energy loss results in heat waste from the transmission lines and transformer points.

Transmission and Distribution Rates – In the deregulated Texas electric market, transmission and distribution services are provided by a separate wires company at a regulated rate. On an annual basis the transmission and distribution service provider may adjust it rates using a Transmission Cost Recovery Factor (TCRF) without having a formal PUC review.

Transmission System – The transmission system brings electricity at high voltages from the power plant to a local substation where it is transformed into lower voltages for delivery through the distribution system to homes and businesses.

Transmission Reliability – Like traffic on a highway, the transmission system must be built to a size with adequate capacity for the volume of electricity it must deliver. Transmission lines are built for heavy-duty service, carry high voltages, and utilize large structures on wide rights- of-way. Transmission system failures are caused by overload, and severe weather such as tornados, hurricanes, and ice storms.
