Ecodesign requirements

Ecodesign requirements mainly cover minimum energy efficiency levels of transformers with a minimum power rating of 1 kVA that are used in 50 Hz electricity networks or in industrial applications.

Energy savings

Power and distribution transformers convert voltages in electricity transmission and distribution grids. Using more energy efficient transformers should lead to energy savings of an estimated 16 TWh per year after 2020. This is equivalent to 3.7 million tons less of CO2 being emitted each year, or half of Denmark’s total annual electricity consumption (32 TWh).
