P. Le Strat

• 2002-2008: Model for breaking down electricity consumption of a territory (Genève, EOSh) and estimation of savings potential

• Design of éco21 program and contribution to its implementation

S. Schneider

2015-2016: Start of task «GIS Energy demand» of the SCCER FEEB&D project

• GIS Swiss heat demand model

• Preparation of phase II du FEEB&D 2017-2020

General frame of ElectroWhat project

• Extend model to whole Swiss territory

• Share experience gained through an efficiency program

Results of the model

For each Swiss municipality, the estimated electricity demand is broken down into:

60 activitiesCollecte et traitement des eaux uséesDépollution et autres services de gestion des déchetsImprimerie et reproduction d'enregistrements….

32 electric appliancesEau chaude sanitaire électriqueEau chaude sanitaire PACEclairageEclairage été/mi-saisonEclairage hiverLave-linge….

Possibility to calibrate with local consumption data to improve the model.

Part 4: Example of impact evaluation of an efficiency measure


Example: efficient lighting in private households.

• Hypothesis: 100% LED (the average power of a light bulb drops down from 40 (W) to 8 (W)

• No rebound effect

• We compare the effect on the load curve between two municipalities having very different socio-economic typology.


Number of inhabitants: ~129’000Important share of activity in tertiary sector

Number of inhabitants : ~8’200Mainly residential

Conclusions

The success of éco21 is based of

• An rigorous analysis of the electricity consumption allowing a ranking of actions based on objective.

• 50% of the budget in accompaniment actions and market transformation, 50% in financial encouragement.

• Evaluation of savings and continuous improvement.

Main goal of ElectroWhat : delivering all required information to act as decision helping tool for planning electric efficiency actions
