COMMISSION REGULATION (EC) No 278/2009
of 6 April 2009
implementing Directive 2005/32/EC of the European Parliament and of the Council with regard to
ecodesign requirements for no-load condition electric power consumption and average active
efficiency of external power supplies
(Text with EEA relevance)
THE COMMISSION OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European
Community,
Having regard to Directive 2005/32/EC of the European
Parliament and of the Council of 6 July 2005 establishing a
framework for the setting of ecodesign requirements for energy-
using products and amending Council Directive 92/42/EEC and
Directives 96/57/EC and 2000/55/EC of the European
Parliament and of the Council ( 1 ) and in particular
Article 15(1) thereof,
After consulting the Ecodesign Consultation Forum,
Whereas:
(1) Under Directive 2005/32/EC ecodesign requirements are
to be set by the Commission for energy-using products
representing significant volumes of sales and trade,
having a significant environmental impact and presenting
significant potential for improvement in terms of their
environmental impact without entailing excessive costs.
(2) Article 16(2) of Directive 2005/32/EC provides that in
accordance with the procedure referred to in
Article 19(3) and the criteria set out in Article 15(2),
and after consulting the consultation forum, the
Commission will as appropriate introduce an implemen-
ting measure for office equipment and consumer elec-
tronics.
(3) Office equipment and consumer electronics are often
powered by external power supplies (EPS) which
convert electricity from the mains power source. The
power conversion efficiency of external power supplies
is an important aspect of the energy performance of such
products, and thus external power supplies are one of the
priority product groups for which ecodesign
requirements should be established.
(4) The Commission has carried out a preparatory study to
analyse the technical, environmental and economic
aspects of external power supplies. The study has been
carried out together with stakeholders and interested
parties from the Community and third countries, and
the results have been made publicly available.
(5) It is stated in the preparatory study that external power
supplies are placed on the Community market in large
quantities, with their annual energy consumption in all
lifecycle stages being the most significant environmental
aspect, and their annual electricity consumption due to
losses for power conversion and no-load amounting to
17 TWh, corresponding to 6,8 Mt of CO 2 emissions. In
the absence of measures this consumption is predicted to
increase to 31 TWh in 2020. It has been concluded that
the lifecycle energy consumption and the use-phase elec-
tricity consumption can be improved significantly.
(6) Improvements in the electricity consumption of external
power supplies should be achieved by applying existing
non-proprietary cost-effective technologies that can
reduce the total costs of purchasing and operating
external power supplies.
(7) Ecodesign requirements should harmonise electricity
consumption requirements for no-load condition power
consumption and average active efficiency of external
power supplies throughout the Community, thus contri-
buting to the functioning of the internal market and to
the improvement of the environmental performance of
these products.
(8) The ecodesign requirements should not have negative
impact on the functionality of the product and should
not affect negatively health, safety and the environment.
In particular, the benefits of reducing electricity
consumption during the use phase should more than
offset potential additional environmental impacts during
the production phase.

(9) The two-staged entry into force of the ecodesign
requirements should provide an appropriate time-frame
for manufacturers to redesign products. The timing of
the stages should be such that negative impacts on the
functionalities of equipment on the market are avoided,
and cost impacts for manufacturers, in particular small
and medium-sized enterprises, are taken into account,
while ensuring timely achievement of the objectives of
the Regulation. Measurements of the power consumption
should be performed taking into account the generally
recognised state of the art. Manufacturers may use
harmonised standards established in accordance with
Article 10 of Directive 2005/32/EC.
(10) This Regulation should increase the market penetration
of technologies that improve the lifecycle environmental
impact of external power supplies, leading to estimated
lifecycle energy savings of 118 PJ and electricity savings
of 9 TWh by 2020, respectively, compared to the
situation without taking any measures.
(11) In conformity with Article 8 of Directive 2005/32/EC,
this Regulation should specify that the applicable
conformity assessment procedures are the internal
design control set out in Annex IV of Directive
2005/32/EC and the management system set out in
Annex V of Directive 2005/32/EC.
(12) In order to facilitate compliance checks manufacturers
should be requested to provide information in the
technical documentation referred to in Annexes IV and
V of Directive 2005/32/EC on average active efficiency
and no-load electric power consumption.
(13) Benchmarks for currently available technologies with
high active efficiency and low no-load power
consumption should be identified. This will help to
ensure the wide availability and easy accessibility of infor-
mation, in particular for small and medium-sized enter-
prises and very small firms, which will further facilitate
the integration of best design technologies for reducing
energy consumption.
(14) Ecodesign requirements for the no-load condition of low
voltage external power supplies address the same envi-
ronmental impact parameter as ecodesign requirements
for the off-mode condition of electrical and electronic
household and office equipment placed on the market
with a low voltage external power supply. As ecodesign
requirements for the no-load condition of low voltage
external power supplies should be more demanding
than ecodesign requirements for off-mode condition of
electrical and electronic household and office equipment
placed on the market with a low voltage external power
supply, the requirements of Regulation (EC) No
1275/2008 of 17 December 2008 implementing
Directive 2005/32/EC of the European Parliament and
of the Council with regard to ecodesign requirements for
standby and off-mode power consumption of electrical
and electronic household and office equipment ( 1 ), should
not apply to electrical and electronic household and
office equipment which is placed on the market with a
low voltage external power supply. Regulation (EC) No
1275/2008 should therefore be amended accordingly.
(15) The measures provided for in this Regulation are in
accordance with the opinion of the Committee estab-
lished by Article 19(1) of Directive 2005/32/EC,
HAS ADOPTED THE FOLLOWING REGULATION:
