High Efficiency Distribution Transformers

The global electricity savings potential from distribution transformers is well over 100 TWh / year. This campaign aims to realise this savings potential, through education and advocacy for minimum energy performance standards.

Energy efficiency of distribution transformers in Europe

Submitted by Roman Targosz on Tue, 2007-10-16 12:46.

By Roman Targosz et al

Losses in distribution transformers account for almost one third of overall transmission and distribution losses. Previous European Copper Institute studies indicated that improving energy efficiency of existing European stock of transformers by 40% would result in about 22 TWh energy savings equivalent to about 9 million tonne of CO2eq. SEEDT is one of the projects developed under Intelligent Energy – Europe programme which converts EU energy policy for today’s energy challenges like energy efficiency. One the main goals is to update and scrutinize knowledge about energy efficiency in distribution transformers in Europe. This paper presents findings of analysis of existing situation.

I feel not much is being

I feel not much is being done to expedite the incorporation of Energy efficient DTs. Leading utilities throught out europe should take the lead.

incorporation of energy efficient transformers

Some large utilities like Endesa, EON are addressing this issue in systematic way. Many other are more or less aware about efficient options and how efficiency pays off.

The SEEDT project, http://seedt.ntua.gr/ under Energy Intellignet Europe Programme proposes actions on this subject. The possible ways to include DT's efficiency in regulation are:

  • Ecodesign directive
  • Energy Services directive
