Transformers

The energy performance of power transformers is currently being improved around the globe.

In the EU alone, total losses from inefficiencies in 2008 amounted to 93.4 TWh per year, equivalent to almost 12 percent of the continent's residential electricity consumption.

A regulation covering this group was adopted in May 2014. The cost‐effective improvement potential through more efficient design has been estimated in about 16.2 TWh per year in 2025, which corresponds to 3.7 Mt of CO2 emissions, with a projected loss of (aggregate of the 10‐20% expected loss through non‐compliance) of 1.6‐3.2 TWh.
