High efficiency transformers can
save more than 200 TWh / year of electricity, equivalent to more
than 100 million tonnes of CO2 emissions
Energy losses in the world’s electrical distribution
networks amount to 1225 TWh. They vary from country to country between
3,7% and 26,7% of electricity use, which
implies a large potential for improvement.
Distribution transformers are the second largest
loss-making component in electricity distribution networks. Transformers
are relatively easy to replace, certainly in comparison with lines
or cables, and their efficiency can fairly easily be classified,
labeled and standardized. Moreover, mature technology exists to
reduce losses by up to 80%.
The worldwide electricity savings potential of switching
to high efficiency transformers is estimated to be 200 TWh. This
savings potential is not only technically advantageous,
but also brings economic and environmental benefits. Taking the
full life cycle cost into account, selecting high efficiency transformers
is often an economically sound investment
decision despite their higher purchase price.
