WSI Launches WSI HourlyTrader™

Weather Leader Provides Real-Time, Graphical, Quick-Decision Tool For The Energy Spot Market

Andover, MA - April 22, 2009 — Weather Services International (WSI), the most trusted global weather solutions provider, today announced WSI HourlyTrader, providing the spot energy market with a highly accurate and user friendly means of analyzing hour-to-hour changes in weather conditions and forecasts that effect electricity usage anywhere in the United States.

This innovative product is powered by a unique observation network that reports minute-by-minute weather conditions for the key demand cities within each of the U.S. power pools. Using WSI HourlyTrader’s real-time weather observations, forecast guidance from domain experts and high resolution models, traders can quickly detect changes in weather patterns before reactions in power consumption occur, and trade accordingly.

“As energy traders know, small changes in the weather can significantly move energy markets. For example, a small rise or fall in temperature for a key load center has the potential to mean tens of thousands of dollars in the energy markets," said Ira Scharf, General Manager of WSI’s Energy and Risk Division. "WSI HourlyTrader provides both the ability to quickly assess the impact of weather conditions, and also the ability to anticipate those changes with timely and highly skilled forecasts, delivering a competitive advantage our customers can apply directly to their bottom line."

In addition, users have access to industry leading forecast data from WSI’s RPM model, including the unprecedented ability to access hourly updated forecasts at 4km resolution. WSI HourlyTrader also delivers enhanced capabilities, such as:

  • Hourly forecasts for key demand cities out four days
  • Operational forecast updated each hour
  • Data presented in both Meteogram and Tabular format
