Telvent to Upgrade the SCADA Systems Controlling Williams Gas Pipeline's Northwest and Transco Pipelines

Market Wire, December, 2006

Telvent GIT S.A. (NASDAQ: TLVT), the Global RealTime IT Company, has been selected by Williams Gas Pipeline (Williams) to upgrade the Supervisory Control and Data Acquisition (SCADA) systems controlling its Northwest and Transco pipelines from OASyS 5.2UX to OASyS DNA. The Northwest pipeline SCADA upgrade will take place in 2006, followed by the Transco pipeline SCADA upgrade in 2007.

Telvent was awarded the contract following a co-engineering project that involved defining the scope, plan and expectations for each of the upgrades. The actual upgrades will be performed using migration tools that will allow Williams to reuse much of the intellectual investment it has made in its existing SCADA systems and will include the implementation of Telvent's gas applications including Gas Device Interface (GDI).

Williams' SCADA requirements include qualities such as expandability, flexibility, supportability, extendibility, enhanced security and audit-ability. Not only is OASyS DNA a flexible, field-proven system that will be able to grow as Williams' needs change, but it is also a highly secure system with a single sign-on implementation, tools designed to track and manage changes, and the ability to easily audit and report these changes in response to internal and external review. As expressed by Manuel Sánchez Ortega, Telvent's Chairman and Chief Executive Officer: "Telvent strives to maximize the value it provides to its clients by providing them with the latest advances in information technology along with options for implementing that technology and world class support. OASyS DNA's robust, secure and modular design will allow Williams to improve the operation of its pipelines and reduce its operating costs over the long term."

Delivering gas for 50 years, Williams, through its subsidiaries, primarily finds, produces, gathers, processes and transports natural gas. The company also manages a wholesale power business. Williams' operations are concentrated in the Pacific Northwest, Rocky Mountains, Gulf Coast, Southern California and the Eastern Seaboard. www.williams.com .
