Good Practice

ENERGETIC TRANSITION OF THE HEATING NETWORK IN CHAMBÉRY

The objectif of the first phase is to reach a use of renewable and recovered energies of more than 50 % for the energy provision of the heating network of Chambéry. The first phase consists of three steps of energetic diversification. The overall objective is to reach a 0 carbon network which is independent from the inflation of fossil energy prizes.

I Description of the measure

Title in original language: Transition énergétique du réseau de chaleur de Chambéry (5ème réseau de France)

Location of CNA: France

Municipality / regional entity: Chambéry

Category of the experience: Strategy
Type(s) of CNA:

Principal nomination: Technological
Secondary nomination(s): Financial

Thematic field(s):

Principal field: Energy 
Secondary field(s): Buildings & construction

Spatial scale: Local
Time & duration:

Start date: 2005
Duration: 1st phase until 2014

Key word(s): diversification, economic and environmental performance

Objectives:

The 3 steps of the first phase which should allow to reach more than 50 % of renewable and recovered energies in Chambéry (58'500 inhabitants): 1: 2008: connection of the energy from waste plant Chambéry Métropole (25%) 2 : 2011 : installation of a biomass heating plant (7 MW) within the network Hauts de Chambéry (12%) 3 : 2013 : installation of a biomass heating plant (2x8 MW) within the basic network (17 %, then 26 % in 2018) In total 54 % in 2014 and 63 % in 2018

Activities:

Step 1: modernisation of the energy from waste plant with heat recovery from two additional furnaces. Establishment of a connection between the two plants Step 2: establishment of a wood energy plant of 7 MW Step 3: establishment of a wood energy plant of 2x 8 MW

Results:

See § 11

II Assessment criteria

Mitigation effects: Very high

The first step of the energetic transition of the heating network allows to reduce the CO2 emissions by 40 000 tons/year which is 10 % of the total emissions of Chambéry and 22 % of the emissions of the housing and tertiary sector

Impacts on adaptation: Neutral

-

Impacts on environment:


- Landscape: Neutral
- Alpine ecosystems / biodiversity: Positive
- Water / soil / air: Very positive
- "Other": None

Reduction of greenhouse gas emissions

Impacts on society:


- Social justice: Very positive
- Regional / cultural identity: Very positive
- "Other": Very positive

The town gets more attractive in terms of energetic and environmental performance. Guarantee for access to energy at a price which is stabilised in the light of the inflation of fossil and nuclear energies

Impacts on economy:


- Employment / job creation: Very positive
- Added value / income: Positive
- Know how / competitiveness: Positive
- "Other": Positive

The wood energy sector will structure its production within the region and will strongly develop. In total the local enterprises worked for about 22 million Euros. Development of know-how of the local enterprises and development of the local wood sector.

Public relations impact and awareness-raising: High

The users and the promoters are choosing the heating network for its economic and environmental performance.

Transferability: Very high

-

Cross sectoral and integrative approach: Very high

This action takes into account all dimensions of a sustainable development: society, environment and economy.

Good governance: High

This action allowed to bring together institutional partners/public bodies (the town of Chambéry and the agglomeration), the managing entity of the network (SCDC-Cofely), the users and managers of the heritage and the actors of the wood sector.

III Executive body and contact information

Executive body: Administration, Individuals, Organizations of civil society, Private enterprises

In the framework of a delegation of this public service The town of Chambéry entrusted the exploitation of its heating network to the SCDC company, a branch of COFELY GDF-SUEZ.
