Heating and Cooling in the local context
The 86.25%, 31.5MW of the total
installed capacity (in terms of
steam or hot water boilers) is
located in the southern part of
this two industrial parks. The
northern part only means 5MW
of installed capacity.

The improvement of the use
of energy in an industrial
area, using renewable
sources (two biogas
production plants : sewage
and bio-waste treatment
plant) and industrial
surplus or waste heat

Role in THERMOS : Pilot city
• Identify and collect required datasets WP1:
– energy sources (biogas, surplus heat, biomass, solar…)
– energy consumers (present and future)
– thermal energy network costs of building (pipes, generation, distribution, storage
…)and providing steam and hot water
• Help the leaders in modeling from a multi-scale multi-vector point of view and use
THERMOS’ application for Granollers district heating network planning (WP2-WP3)
according to our user-needs and challenges (public authority).
• Share the knowledge gained from the experience with the replication city of Cascais
(Portugal), have technicians trained (WP4) and disseminate and promote THERMOS
adoption roadmap among local and regional authorities, energy agencies, industry
and consumer associations (WP5).
• Hosting 1 project meetings (WP1) and hosting one twinning workshop (WP4)

Industrial energy demands
Apart from real measured consumptions for
the 10 monitored activities (the biggest ones
in Eco Congost project) there are estimates
for the rest of activities based on :
-the surface area and economic activity
classification (CCAE) according to ICAEN
sources for industrial processes demand.
-employees and yearly working days for hot
water consumption.

Evolution of industrial users demand
Industrial sector
Two primary industrial
areas have been identified
for action:
Congost and Jordi Camp.
A range of solutions are
being investigated for
both areas including solar
thermal energy, PV
energy, heat exchange
between industries, the
district heating network,
and a cogeneration plant
providing steam and hot
water.

Thermal power demand all along the industrial areas

Expectations and needs...
• Identify and quantify the best way/solutions to build a district heating
system in the city from a multi-scale multi-vector point of view, with a
dynamic local supply and demand.
• Help local energy planners to develop a DH network over the next years
in a consolidated urban area, and be able to reduce local fossil energy
consumption and local GHG emissions.
Target group
• In Spain and Catalonia we have regular contact with local and regional
authorities and networks, energy agencies, public and private utilities,
industry and investors related to thermal energy.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement no
