The Greek demo-site is located in the city centre of Thessaloniki and is composed of a set of 50 residential buildings, 3 energy retail stores and one large commercial facility managed by WVT as utility company together with INNO as energy efficiency services provider. Therefore, the whole demonstration area will represent a common EU neighbourhood and will aim at obtaining real experiences on how EU citizens can participate in and facilitate the deployment of flexibility services supporting the grid operators.

The pilot’s objective is to develop demand-side management models for consumers offering them reduced energy consumption and energy services (comfort, security, etc.) as well as to enable commercial sites to apply flexibility services with the integration of RES such as PV, storage facilities and e-mobility, in order to engage further citizens to actively participate in the REEFLEX journey.

    The Spanish demonstrator is located in Zaragoza and its surroundings (Aragon region, in the North-East of Spain). Aragon is characterised by a large population concentrated in its capital city, which, together with the large number of industrial and service companies, generates a great area of energy consumption. The rest of the region has a very dispersed population (rural area) and a large number of renewable generation plants. To facilitate the integration of these renewable sources, it is proposed that all types of energy consumers and prosumers are incorporated into flexible markets, which is why the Spanish demonstrator consists of residential, office and industrial buildings, covering the main types of consumers in the area.
