Terms You May Hear

Last night at Sharyland Utilities' public meeting held at the Floyd County Friends Unity Center in Muncy, Texas they had a handy little booklet full of all kinds of information available to attendees. I wanted to share the section "Terms You May Hear" because I understand that its a lot to keep up with all the stuff going on with the transmission build out and the wind industry. So, here is a little FYI:


CREZ = Competitive Renewable Energy Zone
Specific area of Texas determined by the PUCT to have superior wind resources, including the Texas Panhandle and South Plains.

PUCT = Public Utility Commission of Texas (www.puc.state.tx)
The Texas regulatory body responsible for protecting customers, fostering competition and promoting high quality infrastructure, including electric transmission lines. The PUCT maintains oversight over Sharyland and all regulated utilities in Texas.

ERCOT = Electric Reliability Council of Texas (www.ercot.com)
An independent agency, overseen by the PUCT, that manages the flow of electric power to 22 million Texas customers. ERCOT's system covers approximately 85% of the state's load and 75% of its land area.

SPP = Southwest Power Pool (www.spp.org)
An organization similar to ERCOT that oversees the planning and operation of an interstate transmission grid covering states including parts of Nebraska, Kansas, Oklahoma, New Mexico, Texas, Arkansas, and Louisiana. Most retail customers in the Texas Panhandle and South Plains are connected to the SPP grid.

FERC = Federal Energy Regulatory Commission (www.ferc.gov)
The Federal Energy Regulatory Commission regulates and oversees energy industries in the economic, environmental, and safety interests of the American public. They effectively perform the same function for the rest of U.S. as the PUCT does for Texas.

NERC = North American Electric Reliability Corporation (www.nerc.com)
NERC is a self-regulating organization, subject to oversight by the U.S. Federal Energy Regulatory Commission and governmental authorities in Canada. They ensure the reliability of the bulk electric system throughout North America by establishing and enforcing technical and operational requirements for all electric utilities.

TDSP = Transmission/Distribution Service Provider
Also referred to as a Transmission Service Provider ("TSP") or a Transmission Owner/Operator ("TO"), a TDSP owns and operates electric transmission lines in ERCOT. Some, like Sharyland, are fully regulated and must follow the guidelines of the PUCT, as well as ERCOT.

CCN = Certificate of Convenience and Necessity
A permit issued by the PUCT that authorizes a TDSP to build a specific transmission line along a defined route.

ROW = Right of Way
Written permission from a landowner to a TDSP that allows the TDSP to build and maintain a transmission line across the landowner's property.

345kV = 345 kilovots = 345,000 volts
This is the nominal voltage of the CREZ transmission lines. By comparison, the voltage supplied to most homes is 120/240 volts.

Collection Station
These are the endpoints to which the 345kV CREZ lines attach. They are also the points to which wind farms will connect to the ERCOT system. They are also referred to as "Stations" or "Substations."

Stakeholder
Any entity (landowner, business, etc.) that could be potentially affected by the location of a transmission line or substation.
