Each seminar in the series discussed the benefits of PROS commercial optimization systems in the natural gas industry. Each seminar included case studies which provided participants an insight to the practical applications of PROS science-based optimization systems. Focused on pipelines, storage, and trading, these seminars enabled participants from various areas of the energy industry to take advantage of pricing and revenue optimization best practices. "These seminars were a resounding success," says Matt Johnson, PROS' Senior VP of Energy. "PROS is continuing to take the leadership role for transfer of our mature revenue management science and technology into the energy industry. Based on the positive feedback of key energy first-movers, we anticipate several more of these innovative, interactive seminars in 2002. These sessions allowed attendees to have access to free, informative business case studies reflecting state-of-the-art energy revenue management." The PROS Trading Optimization System can increase gas trading profitability by 10-15% by generating the optimal routing of supply to market given all pipeline contract constraints, gas purchase and sale obligations, and trading opportunities. The system recommends optimal spot gas buy/sell strategies and provides real-time physical position and opportunity cost data between any two points on the pipeline network. The result is the reduction of the gas scheduling process to less than 60 seconds. The PROS Storage Revenue Management System has been shown to increase revenues from the sale of storage capacity by 7-25% after initial implementations. This system provides pipelines, storage marketers and traders with the ability to maximize revenue from the sale of storage services and contracts. It provides the comprehensive ability to analyze the value of storage using PROS' state-of-the-art revenue management science and to execute and track those deals in real-time. The PROS Transportation Revenue Management System has demonstrated a revenue lift of 7-15% for firm transportation services in both open-season and negotiated sales environments. It allows natural gas pipelines to maximize revenue from the sale of transportation capacity. The system uses PROS' mature forecasting technology to predict demand for transportation contracts and forecast the customer utilization of existing contracts. PROS' price modeling and network optimization technology is used to provide pipeline capacity marketers with an optimal marketing plan that maximizes revenue from the sale of available capacity. These products are based on the PROS Enterprise RM Platform, which uses world leading science, forecasting and optimization to generate revenue and profits for PROS' clients worldwide.
