The European Union has established a framework for setting Ecodesign requirements for energy-related products (Directive 2009/125/EC). The main target is a 20% improvement in the EU’s energy efficiency.
This energy efficiency improvement has already been applied to consumer products such as lightbulbs, vacuum cleaners and refrigerators. It is now also to be applied to medium and large power transformers.
In 2008 it was estimated that transformer losses amounted to 93.4TWh per year. In contrast, by 2025 the savings in losses has been estimated at 16.2TWh per year by using Ecodesign transformers. This equates to a CO2 emissions saving of 3.7Mt.
In terms of a rollout, there has been a two-tier introduction.
