Vénissieux - France

In a context of rising energy bills, the City of Vénissieux entrusted Veolia Energy-Dalkia with the management of a boiler plant and the heating network.

The challenge in this contract was to combine environmental and financial performance with comprehensive management of the heating network. Veolia Energy-Dalkia has overseen the continual upgrade of these facilities to ensure the best user comfort, improve service reliability, contain costs and protect the environment.

• Modernizing equipment to enhance continuity of service.
• Reducing environmental impact of the facilities.
• Diversifying energy sources for better cost management.
• Raising awareness of reduced energy consumption.

• Optimize the energy mix by building a wood-fired boiler (22% of energy) and a gas fired cogeneration plant (27% of energy).
• Replace heating oil with renewable or alternative energies to stabilize the energy bill and the price per megawatthour sold to users by limiting the impact of the volatility of exchange rates and the rising cost of crude oil.

• Installation of continuous emission measurement and analysis equipment.
• Increasing the share of renewable energies in the total energy mix consumed: 22% at present with a medium term goal of 35% thanks to the share of energy to come from wood.

To help customers reduce their energy bills, Veolia Energy-Dalkia hands out information brochures on useful tips for saving energy.

The use of supplies of wood available and harvested in the local Rhône-Alpes region contributes to the development of the regional economy and the promotion of local jobs (handling and preparation).
