REPLICATE Site San Sebastian


Project status



The Spanish city of San Sebastian has 186 062 inhabitants and was voted European Capital of Culture 2016. It is a touristic and commercial centre with strong emphasis on services and events. In recent years, San Sebastián has become one of the leading European cities in the context of smart and sustainable cities, largely because of its commitment to science, technology, economic development, sustainability and culture.  The city is also an internationally recognized culinary destination. 

San Sebastian  has an integrated smart city strategy with the particular objective of becoming a nearly zero-energy city. San Sebastian wants to enhance the transition process to a smart city in three areas: energy efficiency, sustainable mobility and ICT infrastructures.

Demo Site Expected Impact

* Detailed information regarding the technical and financial performance will be available at a later stage.

The REPLICATE team is working to accelerate the deployment of innovative technologies, and organisational and economic solutions to significantly increase resource and energy efficiency, improve the sustainability of urban transport, and drastically reduce greenhouse gas emissions in urban areas. Therefore, the project aims to enhance the transition process to a smart city with the following:

  • energy efficiency: achieve energy savings in relation to the existing situation in retrofitting buildings and in district heating;
  • sustainable mobility: integrate sustainable electric vehicles, recharging systems and an Information Mobility System;
  • integrated ICT infrastructures: develop new sustainable and cost-effective services to citizens providing integrated infrastructures that improve efficiencies in the use of local public resources and the delivery of public services


Buildings and energy

* Detailed information regarding the technical and financial performance will be available at a later stage.

The solutions demonstrated in San Sebastian include:

Energy efficiency in buildings

  • Retrofitting the building envelope
    • 156 dwellings and 34 commercial premises spread over 18 350 m²

Energy systems integration

  • District heating and cooling
    • District heating system to give service to more than 1500 new properties and 156 existing dwellings. The system is fired by a power plant with 7400 kW of power and two 1400 kW biomass boilers. It will lead to a reduction of 35% in primary energy consumption, where 90% of this energy is renewable, and 85 % reduction of CO2 emissions.
  • Biomass boilers
  • Smart street lighting

Mobility & Transport

  • Electric, hybrid and clean vehicles
    • 2 full electric and 2 hybrid buses for line 26, linking the district with the city centre
    • Public electric vehicle acquisition – 4 e-cars and 6 e-motos for the municipal fleet
    • Private electric vehicles: 12 e-taxis, 5 vehicles for the distribution fleet, as well as 12 vehicles and 20 e-motos
    • Charging infrastructure deployed in the city


  • Neighbourhood energy management system
    • A demand side platform will be developed for the monitoring of residents’ consumption to foster sustainable behaviour
  • Urban data platform
    • Smart city platform with integrated services: open data and citizen participation services, IP services deployment in Poligono 27 and high-speed connectivity network deployment for the whole city.
  • Travel demand management
    • Mobility smart city platform and development of advanced mobility services
  • Traffic control system
