incorporation of energy efficient transformers
By Roman Targosz / Published on Mon, 2007-11-12 16:20Some 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:
