1. Renewable / PV Policy – City of Lorient

2. Climate Action Plan: « 3x30 » by 2020 on municipal buildings / public lighting / vehicles
-30% CO2 emissions (baseline = 1990) (only -300t / 2014: here we are!)
30% energy efficiency (-8GWh / 2014 : long way to go…)
30% renewable energy (and 50% renewable heat on buildings)  wood and solar energy
Lorient 2014 2015
 Overall Energy consumption
(municipal buildings, public lighting ~9000 lamps, vehicles)
33,5 GWh 32,6 GWh
 Electricity consumption (municipal buildings ~300 000m²) 7,3 GWh 6,7 GWh
Electricity bills (municipal buildings)
(due to the strong decrease of electricity prices)

4. Photovoltaïc: municipal action plan (octobre 2015)
Main goal: x 2 of PV power by 2020 on municipal buildings  + 125 kWc
-PV budget line  60 000€ / year (investment) : hard to achieve PV goal with just this
funding…
-New crowfunding scheme for PV
In order to amplify city’s PV budget
-Keeping technical skills for city’s workers, in order to implement new PV plants with a
lesser cost
-Reduction of electricity consumption espacially on PV powered sites  Mainly in schools
-Promoting the new crowdfunding scheme to local stakeholder, in order to developp it
 Espacially with commercial buildings, fishing activity, …

5. New crowdfunding scheme
Citizen own the PV pannels
MADE IN FRANCE
( « OnCIMè » company)
(on s’y met means something
like « let’s do it » )
Renting 9000€/y for 45kWp ,
during 15 years
(city uses electricity credit
line to rent the PV panels)
Lorient city
-Rents Solar
pannels
-Purchase other
equipments
(inverters,
ballast, …)
Installation of PV pannels by city
workers
+ awarness campaigns,
during 15 years

6. Citizen Oncimè company :
« Brittany citizen energy » non profit organization (BEC) (2009) 120 members
First project: Mellac solar roof (2009-2013)
BEC was looking for new opportunities:
- New funding schemes (PV « national » prices made a huge fall during the years 2011-2013)
- Looking for ways to involve more people
- Wishing to work with children
New « tool »: OnCIMè participating company
 1 people= 1 voice – 66 shareholders – 38 750€ capital
 Executive comittee of 11 people (including 2 by drawing of lots !)
Co-ownership of solar pannels
French made panels (low CO2 for manufacturing)

7. First test of « behind the grid » PV plant: Kermelo school (2014-
2015)
15 kWp / 100 m²
60 pannels of 250 Wp, one micro inverter per pannel
Price : 35 000€ (no VAT!),  2,3€/Wp
Ballasted supports (no hole in the roof!)
Production / y.  17,5 MWh
Self consumption : 90%
Covert ratio (PV self consumption / total): >20 %
kWh price: 11c€ /kWh

9. First results
2006 - 2015: 125 kWc
2016 : 4 new plants !
- Lanveur School : 9kWc
- Keroman School : 36kWc
- City hall + Kersabiec School : 45 kWc
(crowdfunding)
Total 2016 : + 90kWp
(2015-2020 goal = +125kWp)
