Reasons for Ecodesign

Transformer losses represent around 2.5% of EU energy consumption.

Using more energy efficient transformers should lead to energy savings of an estimated 16,2 TWh per year which is half of Denmark’s total annual electricity consumption (32 TWh).

These energy savings represent reduction of 3,7 Mt emissions of CO2  per year.

This is the reason of the implementation of the program: 20 - 20 - 20

  • 20% reduction of greenhouse gas emissions
  • 20% higher energy efficiency
  • 20% of total energy generated from renewables

The rules for EcoDesign entered into market as COMMISSION REGULATION (EU) No 548/2014 in 21.5.2014 implementing Directive 2009/125 / EC of the European Parliament and of the Council with regard to small, medium and large power transformers.

1.10.2019, a new COMMISSION REGULATION (EU) 2019/1783 was issued amending the first Regulation (EU) no. 548/2014 implementing Directive 2009/125 / EC of the European Parliament and of the Council.

Main outcomes of initiative

  • Reduction of load losses and no-load losses for transformers up to 3 150 kVA and Um ≤ 36 kV
  • Increased efficiency of the transformers
  • Reduction of total operating costs

In average electricity passes through up to 5 transformers as it travels from the power plant to the end customer

Decarbonization

TWh of electric power saved by lower losses

million tons of reduced CO2 emissions

These saving are nearly equivalent to current consumption of the Czech republic.

In average, with using BEZ transformer variant EcoDesign 2, in 30 years lifetime we can reduce CO2  as equivalent of:

kilometers driven by an average passenger vehicle

liters of consumed gasoline

tons of coal burned

homes' electricity use per one year

Operating costs and energy savings

Example of total losses comparison for BEZ Oil Transformers, Rated Power 1 000 kVA, up to 24 kV

Note: operating costs for 30 years subject to electricity cost 0.16 Euro per 1kWh in the first year of operation, with subsequent expected annual rise by 0% annually, and transformer load factor of 0.7; 1kWh equals to 0.513 kg of CO2 

€ Total Savings (no rise in electricity prices included)
