ABB to connect U.S. and Mexican power grids

2005-12-22 - Back-to-back HVDC system will boost grid reliability, enable power trading

Zurich, Switzerland, December 22, 2005 – ABB, the leading power and automation technology group, has been selected by Sharyland Utilities to design and build a new high-voltage direct current (HVDC) intertie between the U.S. and Mexico. The system will connect the Texas utility with Mexico’s CFE, enabling both transmission grids to share reserves and ultimately facilitate cross-border trading.

"ABB’s cutting-edge HVDC technology will boost grid reliability," said Peter Smits, head of ABB's Power Technologies division. "Interconnections of power grids between countries add value to utilities and consumers, and lower costs."

The installation will be a back-to-back system capable of delivering 150 MW of power in either direction. It will also provide black start capability, an important reliability-enhancing feature in which normal operations can be suspended and a safe flow of power provided to help restore affected areas. As a non-merchant facility, the line will be available to all Texas interconnected energy providers as an “open access tie”.

“This project is essential to the development of the area,” says Mark Caskey, Sharyland Utilities’ General Manager. “It will provide low-cost power to a growing market, and it will strengthen the local grids on both sides.”

ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 103,000 people.
