2 4 Energy core businesses Production Distribution Sales & Marketing Energy services 1 st ELECTRICITY SUPPLIER IN THE FRENCH-SPEAKING PART Mission : ensure a reliable, sustainable and competitive supply 750 Employees 300'000 end customers Area : Vaud, Valais, Fribourg and Geneva

3 INNOVATIVE PROJECTS- ROMANDE ENERGIE / EPFL 3

4 EPFL - SOLAR PARK Largest urban solar park in Switzerland 25 roofs and facades installed capacity of more than 2 MW p Roof area : ~ 15'000 m2 Inauguration: May 19, 2015 Production : ~ 2 GWh/year (average consumption of 550 households and about 3% of the annual EPFL consumption) 4

5 LECLANCHÉ - ENERGY STORAGE High-performance titanium Lithium-ion cells Lifetime : ~ 15,000 charge-discharge cycles Storage capacity : ~ 500 kwh (f. ex. 2'500 m 2 PV) Connected to EPFL PV park Start : August 26,

6 GRAETZEL PV & SUN SHIELD 300 m 2 surface with dual function : Electricity production Suns shield to reduce cooling energy 6

7 EPFL ELL BUILDING - COLORED PV FAÇADE Patented surface treatment (Kromatix ) : 105 m2 of photovoltaic panels 10 kwh/year Little yield loss Optimized integration in the existing building architecture 7

8 SEWAGE TREATMENT PLANT OF MORGES WASTE WATER DISTRICT HEATING Project with the city of Morges and ERM (Intercommunale Association for the wastewater treatment of Morges area) 8

9 WASTE WATER DISTRICT HEATING - SIMPLIFIED SCHEMATIC DIAGRAM Treated water output Water intake Filters Heat exchanger Heat pumps Ambient heating Water outlet Ambient cooling low temperature Ambient cooling high temperature Open system Closed system 9

10 WASTE WATER DISTRICT HEATING - BENEFITS OF LOW ENTHALPY NETWORK Low energy losses between the power source and the consumer No pipe insulation Decentralization of heat and cold Winter heating with the heat pump Summer cooling by reversing the heat pump Most of the distributed energy is renewable 10

11 ENERBOIS In collaboration with the sawmill «Scierie Zahnd SA» 11

12 ENERBOIS - SPECIFIC CONTEXT - SPECIFIC SOLUTION Near Ruyeres (VD) rural environment Low proximity thermal demand Thermal power (potential) : 14MW Fuel with 50% water mass Sawdust available : 140'000 m 3 Agricultural land near the sawmill 12

13 ENERBOIS - KEY FIGURES Power Electrical energy output 14 MW th 4,1 MW e 30 GWh/year (8 300 household/year in electricity) Thermal energy output 36 GWh/year Pellets production t/year (5 000 household/year in heat) 13

14 ENERBOIS - PRODUCTION PROCESS Produce and supply electricity, heat and pellets to customers by minimizing its impact on the environment 14

15 ENERBOIS ENVIRONMENTAL EFFICIENCY CO 2 balance Traffic Heat recovery Processing sawdust Environmental integration Neutral CO₂ released during combustion = CO₂ absorbed by the wood in his life Reduction of nearly trucks/year ( Wood waste - recycled on site - production of electricity, heat and pellets) Combustion gas used for drying sawdust, sawmill wood and to heat several buildings Pellet production (heat 5,000 households/year, energy equivalent to 10 million l domestic fuel oil) Architecture to ensure optimal integration into the landscape 15

16 ENERBOIS - CIRCULAR ECONOMY 16
