    EcoDesign Regulations

    • EcoDesign Regulations

    The EcoDesign regulation came into effect on 11th June 2014 and has been published in the Official Journal of the European Union. This new legislation imposes, within the EU, the maximum level of losses for transformers commissioned from 1st July 2015, but is also applicable to transformers purchased after 11th June 2014.

    After 1st July 2015, it will not be possible to place on the market or commission transformers not fulfilling these minimum requirements and manufacturers will be fully responsible in applying the law.

    After the date of entry into force, manufacturers should not engage in new framework contracts for transformers with energy efficiency specifications below the minimum requirements outlined in the regulation.

    Framework contracts signed before 11th June 2014 can go on until the end date, even with deliveries after 1st July 1 2015.

    Rational : European Union commitments

    The EU is implementing its «20-20-20» program by 2020:
    • Reduction of  20 % of greenhouse gases emission 
    • Reduction of  20% of energy consumption 
    • Reach 20% from renewable energy in total production 
    • Power Transformer losses represents about 2.5% of total EU energy consumption
    By 2020, savings of approximately 16TWh/year are achievable with the new regulation

    EcoDesign aims for two major objectives on the Transformer product:
    • Reduce electrical losses (1 step in 2015/ 2nd step in 2021)
    • Clarify and make more visible indication of performance
    Harmonisation of maximum loss levels in the European Union.

    Efficiency request on medium power transformers for the 1st time.

    EcoDesign impact on Transformers

    Fluid filled and cast resin Transformers: reduced level of losses for fluid filled distribution and cast resin transformers up to 3150kVA

    Medium power and power transformers:
    • Level of Peak Efficiency (Mix of load losses and no load losses) for transformers >3150kVA
    • No regulation as of today for transformers >3150kVA
    • Dry type transformers up to 10MVA  36kV
    • Special transformers are not impacted by this regulation
    • Significant increase of Equipment cost and weights/dimensions
    • Reduction of operational cost (total cost of ownership optimised)
