Running Cool for Lower Energy Costs

Today, hundreds of utilities are benefiting from the use of Amorphous Metal Distribution Transformers(AMDT's) in their power distribution systems. Many more utilities can benefit from a strategic program of replacing conventional distribution transformers with AMDT’s. This could result in annual energy savings of approximately 27 terawatt-hours (TWh) of core losses in the U.S.A. alone. These savings enable utilities to cost-effectively accommodate longterm growth in demand for power.

PROJECTED ENERGY SAVINGS USING Metglas^®AMDTs

In the year 2004, it was estimated that total energy savings for the regions listed would amount to 81(TWh) of core loss reduction per year, or the equivalent of US $6.1 billion dollars annually. The reduction in the production of CO₂, a major contributor to global warming, would be 51 million tons yearly.

“... new transformer core designs are emerging that use amorphous metal instead of the traditional silicon steel. These amorphous core transformers … offer up to 80 percent lower core losses than conventional transformers”.
