Telvent DTN Awarded U.S. Patent on Configurable Weather Alerting Technology

December 1, 2009 – Telvent (NASDAQ: TLVT), the IT company for a sustainable and

secure world, announced today the U.S. Patent and Trademark office has awarded

Telvent DTN a patent recognizing its unique and configurable weather alerting

technology. This flexible application provides automated notification of weather

impacts based on subscriber-defined parameters. With it, customers get precisely the

weather alerts each needs to make the best operational decisions for its business.

With this patent award (U.S. Patent No. 7,602,285), Telvent DTN is the only provider

offering customers the ability to uniquely define the types of weather alert each

requires, including specific weather parameters, significant hazard thresholds, and

precise geographical areas of interest. This exclusive customer-configured alert service

can be applied to stationary or mobile assets and is available 24 hours a day, making

it a powerful business asset – especially for aviation, energy wind farms, ground

transportation, public services and utilities.

For example, an air ambulance service relying on Telvent DTN’s agile weather alert

service could receive a real-time wind warning for not only the current location of

each of its in-flight assets but also for the flight plan of the helicopter. Travel

Information Systems now can receive road-segment alerts of hazardous driving

conditions. Meanwhile a wind farm operator can safely evacuate workers from a

wind turbine in advance of a dangerous lightning strike, based on the advance alert.

And the electric power transmission authority can receive customized alerts for

discrete sections of transmission lines, using weather information to empower the

new SmartGrid that lead to better decisions, fewer outages, and faster restoration

after a storm.

“Yes, we are excited about this patent award,” affirmed Manuel Sanchez, Telvent

Chairman and CEO. “Telvent continues to focus on delivering cutting-edge

technology that supports information management efficiency, which ultimately

supports sustainability. This patent award reflects our role as a leader in technology

innovation.”

Telvent DTN has been advancing the production and delivery of news and information

since 1984. Today, it is one of the most trusted providers of timely and accurate

business information.
