Ameren Enters Alliance Agreement for Technology Exchange with Hitachi Power Systems America, Ltd.
Speaking at an Edison Electric Institute conference, Ameren Corporation (NYSE: AEE) Chairman, President and Chief Executive Officer Gary Rainwater announced that Ameren has entered into a unique alliance agreement with Hitachi Power Systems America, Ltd. The agreement will allow both companies to benefit from technology exchange in the areas of air quality control and efficient power generation.

Under the 1990 Clean Air Act, Ameren companies were required to reduce total annual emissions of sulfur dioxide by about two-thirds by the year 2000. The Ameren companies had started to reduce emissions well before the act was passed and met this goal well ahead of schedule, largely by switching to low- sulfur coal.

The Clean Air Interstate Rule (CAIR), which became law in 2005, requires significant further reductions in SO2 emissions from coal-fired power plants. CAIR also requires significant additional reductions in nitrogen oxide (NOx). Another set of new regulations\-the Clean Air Mercury Rule (CAMR)\- establishes the first requirements for mercury reductions in the world. Meanwhile, interest is growing worldwide in controlling carbon dioxide (CO2), a leading "greenhouse" gas.

"Getting to the next level of emission reductions will require significant investment of capital and intellectual resources," Rainwater said. Ameren has stated that it now estimates its costs to meet the new regulations will range between $2.1 and $2.9 billion through 2015, unless state regulations require further reductions.

To help Ameren address future reductions in SO2, NOx, mercury, CO2, and other pollutants, the multi-year technology exchange agreement with Hitachi will give Ameren access to the groundbreaking work Hitachi is doing at its technology centers in advanced air quality controls and power technologies. This research work includes high-efficiency boilers and integrated gasification combined cycle (IGCC). Additionally, Hitachi will be able to study technologies outside of the laboratory at Ameren's operating fossil fired power plants.

"Access to this technology is critical as we evaluate our options for future baseload generation additions," Rainwater said. "Our alliance agreement allows us to build on Ameren's legacy as a leader in lowering emissions as we plan projects and investments that will help our industry meet emission standards over the next decade."

Bob Powers, Ameren's Vice President of Generation Technical Services, led negotiations with Hitachi. Powers stated, "Hitachi proved to us that they have world-class technology in both Air Quality Control and Power Generation Systems. Hitachi is also an innovative company with a responsive management team."
