BIOMASSE - CENTRALES THERMIQUES

BIOMASS/THERMAL POWER PLANTS

Missions

The district supplied by the heating network will grow from 43,534 m² in 2011 to more than 460,000 m² by the end of 2022 with an average growth rate of 37,000 m²/year between 2012 and 2022.

The heat network mainly provides heating for the buildings. Domestic hot water is partially provided by solar equipment. The network is linked to the Odysseum power station to power the decentralized adsorption cooling units.

The maximum heating capacity is 5.1 MWh, based on an annual consumption of 30,000 MWh in 2022 for a 460,000 m² habitable net surface area (65 kWh/m²).

SERM implements and supports urban development projects. The Port Marianne district is one of Montpellier’s seven main sectors and represents a major development site, along with Odysseum. Experiencing strong urban growth, with the construction of numerous residential buildings, the district is home to major cultural venues, green spaces, social infrastructure, sporting and leisure facilities, and schools.

SERM selected setec  to design and build the biomass power station with an organic Rankine cycle system to serve the Parc Marianne, Rive Gauche, J Coeur and future République districts.

Challenges

This project is innovative in terms of producing electricity from low-temperature heat by combining one of the two wood powered generators with an organic Rankine cycle system. The cooling circuit of this system will be connected to the 90°-60°C network and produce continuous electricity (700 kW). setec  has applied its expertise in organic Rankine cycle systems. This operation is a first in France.
