Transmission

CVPS has over 600 miles of tranmission lines, and about 130 substations across the state. We have over 20 hydro generation stations, two gas turbines, one diesel plant, and 20 dams.

A control center at the company's headquarters in Rutland operates 24 hours a day, and directs all switching for the transmission system via a Supervisory Control And Data Aquisition system. This system is operated via computers, and automatically controls over 70 substations, as well as all generation facilities, over 30 transmission switches, 650 control points, multiple data and communication systems, and over 2,000 alarm and status points.

The controllers also direct the service restoration efforts on the transmission system, substations, and distribution lines involving substations, if there are outages or repairs needed. They also coodinate with Vermont Electric Power Company, better known as VELCO, the state's transmission company, as needed; and ISO New England, a regional transmission organization that monitors and ensures New England's constant power supply.

Open Access Transmission Information

On Feb. 1, 2005, ISO New England and participating transmission owners implemented a Regional Transmission Organization (RTO) governed by ISO New England FERC Electric Tariff No. 3 - Section II Open Access Transmission Tariff (RTO OATT).  The RTO OATT superseded the OATT’s of all Participating Transmission Owners, including the CVPS OATT No. 7.  The RTO OATT covers transmission service on all network facilities including pool transmission facilities and the Highgate Converter Facilities. 

All transmission service types are briefly explained in the ISO New England matrix (see Transmission Service Types), which also contains application information.
