The biomass heat network project in the Landagoien district has moved from study to implementation. Several public facilities, including the community swimming pool, municipal buildings, and the Saint-François-Xavier college, are now supplied by this local renewable energy. This heating and domestic hot water production system reduces reliance on fossil fuels and, consequently, greenhouse gas (GHG) emissions.
The Basque Country Community supported the project's genesis through feasibility studies for the municipality of Ustaritz. SPL Pays Basque Aménagement then managed the operation as the concessionaire of the heat network.
This inauguration concretizes the Territorial Renewable Heat Contract, launched in 2023 by the Basque Country Community and ADEME. This tool has supported 124 public and private projects, financed 21 renewable heat production facilities, and carried out 46 decision-support studies. These projects generate over 15,300 MWh of annual renewable energy production and avoid nearly 3,500 tonnes of CO₂ each year.
Building on these results, the Basque Country Community and ADEME have extended their partnership until 2030. With a budget of 3.7 million euros, it will finance studies and investments. €225,000 is also allocated for the program's animation by the Basque Country Community, in partnership with the Association of Forest Municipalities of the Pyrénées-Atlantiques. This second contract will support new biomass, geothermal, solar thermal, waste heat recovery, and heat network operations across the territory.
This partnership aims to provide local authorities, businesses, social landlords, and project developers with the necessary technical and financial means to achieve local energy transition and further leverage the renewable resources of the Basque Country, in line with the Climate Plan objectives.
The total ex-VAT budget for the Landagoien biomass heat network is €1,430,000. The Basque Country Community contributes €264,000, the State / ADEME (Heat Fund) €521,500, the State / Green Fund €150,000, Europe / FEDER €250,000, and SPL Pays Basque Aménagement €244,500.
