Phase I: 2010 – 2012

Background: Electricity target of lower Austria: :

100% of electricity from renewables in 2015

Energy efficiency is a precondition to increase

the share of renewables in the electricity market

Target of the initiative: exploitation of electricity

saving potential in private households

Electricity saving family

Electricity saving contest for households

Energy consulting for free at the start

Incl. report

Suggestions for improvements

Energy meter for free

All participants were asked to document the

electricity demand monthly „Electricity dairy“

Analysis was offered

Possibility for comparison

Awareness activities using public media

(advertisement in newspaper)

Promotion through “energy hotline”

Smart Meter in some regions

Energy consulting after one year

Final event with regional minister

Prices for families with the highest

savings (absolute and relative)

Statistics

Number of participating families 229 (310)

Conclusion

Targets of the project have been fulfilled

10% - 15 % of savings with energy consulting realistic

No loss of comfort or high investments were mentioned

Willingness for investment mainly for electric appliances

No significant influence of smart meter over the period

Very high savings sometimes caused by “special

effects”
