CHICAGO, ILL. - April 22, 2008 : – Prolec GE's amorphous metal distribution transformers (AMDT) have been ecomagination certified by GE based on their ability to improve the efficiency of electrical power distribution. Prolec GE is a joint venture between GE Energy and Xignux.

Prolec GE's AMDTs received GE's ecomagination certification after completing the company's rigorous environmental and operational evaluation. Ecomagination is GE's commitment to address challenges such as the need for cleaner, more efficient sources of energy, reduced emissions and abundant sources of clean water.

"As energy consumption continues to soar, we are leveraging proven transformer core technology, invented and patented by GE, to provide the marketplace with products that boost productivity. This allows existing power distribution networks to increase their capacity while minimizing their environmental impact," said Bob Gilligan, general manager of GE Energy's transmission and distribution business.

These energy savings are realized because amorphous metal, during its formation process, adopts a random structure (similar to glass) enabling lower losses in the transformer core. Widespread adoption of these transformers could have a substantial impact on the environment. In the United States and Mexico, electric utilities and end users install more than one million distribution transformers each year. If all of these distribution transformers used GE's amorphous metal core technology rather than high-efficiency silicon steel, the annual electricity savings would be approximately 750 million kWh, which is equal to the amount of electricity used by more than 800,000 average U.S. households annually. These energy savings could avoid more than 465,000 tons of CO2 emissions from traditional U.S. electricity sources, which is equivalent to the impact of removing nearly 90,000 cars from U.S. roads for one year. In addition, these ultra-efficient transformers exceed the United States Department of Energy's minimum efficiency standards two years before they take effect in 2010.

Prolec GE's amorphous metal core distribution transformers also provide cost sa vings to utilities over their lifetime. A typical electric utility serving half a million customers installs 4,000 distribution transformers. This typical utility could realize an equivalent first cost savings of more than $800,000 by choosing the amorphous metal core technology over high efficiency silicon steel.

Wind farm owners are one of the many beneficiaries from the use of low-loss amorphous-core transformers. These transformers reduce no-load transformer losses by approximately 65% and increase wind plant output by about 0.2% for an incremental purchase price of about 0.1%.

Amorphous metal transformers allow wind farm owners to maximize their profitability and productivity with proven technology. They allow for a very high return on a virtually risk-free incremental investment, while delivering energy efficiency benefits that are consistent with the wind industry's environmental image.

"We are helping utilities reduce their carbon footprint by increasing their energy productivity, while reducing our own impact on the environment as the manufacturing process for amorphous metal cores requires significantly less energy than the production process for silicon steel cores," stated Jorge Lozano, president of Prolec GE in Mexico.

Prolec GE is a joint venture between Xignux, S.A. de C.V. and the General Electric Company. Xignux is a group of leading Mexican companies in the electrical, automotive, and food sectors. GE is a world leader in the electrical, power systems, medical, aerospace, telecommunications and financial sectors. Prolec GE is a leading manufacturer of oil-filled transformers in the residential, commercial, industrial and power segments. Its experience and quality systems, as well as its geographical location in Monterrey, Mexico, place it as a strategic supplier to serve the NAFTA and international markets.
