AspenTech Implements Energy Optimization and Management Solution for BP Texas City Complex

09/02/03
Aspen Utilities(TM) enables BP to provide steam and power to major refining and chemicals site at lowest total cost and with reduced environmental impact

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sept. 2, 2003-- Aspen Technology, Inc. (Nasdaq: AZPN) today announced that it has begun implementation of an energy optimization and management system for the BP Texas City refining and chemicals complex. The system is based on the Aspen Utilities(TM) product and will enable BP to make more effective decisions that help the company supply electricity and steam to the site at the lowest total cost and with reduced environmental impact.

The energy optimization and management system will help BP predict and manage the power and steam demands for the entire facility, based on a sophisticated model of the plant operations. The system uses analysis and optimization tools to ensure that overall energy consumption is minimized and that appropriate supplies are delivered at the most favorable cost, based on an economic assessment of the alternative sources. These capabilities will allow BP to maximize its return on investment from a state-of-the-art cogeneration plant, currently under construction, which will become the major supplier of the site's electricity and steam.

"Achieving a secure and low-cost supply of energy and steam is of vital importance to our operations," said Terry Harclerode, Manager, Commercial & Business Relations at BP's South Houston Texas City Site. "We believe that the energy optimization and management system will provide our managers with the ability to identify the operating strategy that delivers the greatest overall financial benefits to BP. Optimizing the way we utilize our new cogeneration facility and minimizing the site's manufacturing process unit energy needs will also result in more reliable utility supplies and significant environmental benefits for the Texas City Operations."

The cogeneration plant will provide BP with the option of exporting any excess power to external customers, resulting in an additional potential source of income. The energy optimization and management system will provide plant and energy supply planners with accurate information about the available capacity and the cost of production, enabling more profitable business decisions to be made. This real-time information will also allow the site to decide to import electricity if the price is advantageous.

Energy costs are among the largest operational expenses for integrated refinery and chemical operations like the Texas City complex. The BP site features one of the largest and most complex refineries in the world, with a throughput of 480,000 barrels of crude oil daily, and a wide range of products including low-sulfur gasoline, heavy fuel and petrochemical feedstocks. The adjacent chemicals facility has nine process units, and produces a range of products based on the feedstocks supplied by the refinery.

"Major production sites like the BP Texas City operations need effective decision-support tools to optimize the way they use and source energy," said David McQuillin, President and CEO of AspenTech. "Aspen Utilities provides companies with a simple tool that gives them the information they need for both day-to-day operational management and long-term strategic planning. This knowledge can deliver significant benefits including lower energy bills, improved asset utilization and reduced environmental impact."

Aspen Utilities is part of the Aspen Engineering Suite(TM), an essential element of AspenTech's solutions for enterprise operations management in the process industries. These integrated, enterprise-wide solutions combine engineering and manufacturing/supply chain technologies to help companies optimize the way they engineer and run their manufacturing and supply chain operations.
