SUNREF Workshop
June 8th - Field trip
As part of the SUNREF Partners’ Workshop organized
by AFD, a one day on site visit of different facilities is
organized in order to discover and discuss different
types of energy production processes. Visits are
organized in partnership with ADEME and SER. In total,
the group will visit 4 locations: 2 sites on Renewable
Energy and 2 sites on Energy Efficiency.

Description of the locations
Canto-Perdrix wood combustion heating system: In November 2015,
Canto-Perdrix (100% owned by Dalkia) created a new wood combustion
heating system in Martigues that aimed at providing both lower tariffs for
electricity and heat to the municipality as well as diminish the previous
emissions of such energy production. The new system is expected to reduce
by 59% the total yearly emission of CO2 of the energy production process
and allow Canto-Perdrix to reduce prices for energy by 10%.
LA POSTE’s solar rooftop photovoltaic system: POSTE IMMO, real
estate subsidiary of LA POSTE Group, has signed a partnership with
URBASOLAR for the construction of photovoltaic plants on the sites of the
LA POSTE Group. The panels are installed on the roof of mail sorting
centers. Since the beginning of this partnership, 45 sites have been
equipped. The total area covered by the photovoltaic panels is 85 000𝑚2
which allows an annual production of 5 500 MWhm, the equivalent
consumption of 2000 households. This solar system insures that 2 000 tons
of CO2 are avoided per year.
Solamat Merex: This is an industrial waste incinerator with a capacity of
60,000 tons / year. The incineration process produces a volume of 10 tons /
hour of steam that reaches 235 ° C. This steam can be used either in a heat
network or be converted into electricity. Here, the steam engine provides
about 95% of the electricity used by the site during the year.
Coca Cola’s plant: The plant, which produces 7days/week – 24h/day is
responsible for bottleling the groups beverages. Its steam production is
ensured by a conventional gas boiler system. The plant is equipped with an
economizer that allows heat to be recuperated and stored in the combustion
fumes to be injected later into the boiler inlet. The inlet was over-equipped
with a capacitor. This allows the energy contained in the steam to be
recuperated; this is so-called low temperature heat (less than 50 degrees
Celsius). The low temperature heat is sent to the sugar solution workshop
necessary to beverages which operates at 26°C. The condensing
economizer saves 8% combustion efficiency compared to a standard saver.
