Three project pilot sites have been preselected to cover different climatic and socio-economic environments for deployment and validation of the HESTIA solution
Pilots can provide a wide diversity of demonstration opportunities in terms of:
The Italian pilot of HESTIA is located in Sardinia, in the village of Berchidda, home to 3000 inhabitants.
Since January 2021, the Municipality is officially the owner of the electricity grid (ring infrastructure) in both the town centre and the surrounding rural area and serves as the DSO in the form of AEC (Municipal Electricity Company).
The Municipality plans to upgrade the electricity grid with smart grids and promote innovative initiatives along the entire electricity supply chain, involving all stakeholders in the area. HESTIA is key in supporting the local energy transition strategy with the European know-how of the consortium on demand response. Berchidda, in turn, can provide valuable insights on how to implement, communicate and incentivise participatory demand response in small/medium towns, which represent the most common settlement configuration not only in Italy but also in Europe.
Around 30 households are expected to be recruited to participate in the HESTIA pilot.
Geographical locations: City of Palaiseau, France
Climatic zones: Oceanic climate temperatures, with averages of temperature of 11°C, rainfall of 50 mm per month and of 1,800 hours of sunshine per year
Population densities: 1500 households
Number of households involved: 40 houselholds
Surface and Altitude: Over 22ha and includes 4000 m2 of shops/businesses, 1500 dwellings
Potential outreach immediately after project: 2000 dwellings as part of the City of Palaiseau
Energy systems and energy req.: Wood-fired heating network, urban lighting equipped with Lifi, recharging stations for EVs, an aquatic centre equipped with thermal solar panels
Existing RES share and level of smart metering equipment available at the site: Biomass-fired boilers for the heating network. Thermal solar panels of 120 kWp distributed over 63 collectors. PV installations are considered for public areas such as the pool car park (EV charging), in the form of PV canopies.
Total RES share: 6,300 MWh generated for the heating network to which all the dwellings are connected.
Geographical locations: Voorhout, Netherlands
Climatic zones: Climate widely corresponds to Central European weather conditions, with an average daily high temperature of only 14 degrees centigrade
Population densities: 15,620 inhabitants
Number of households involved: 46 houses (29 phase 1 & 17 phase 2)
Surface and Altitude: Area of 12.59 km2 of which 0.33 km2 is covered by water and had a population of 14,792
Potential outreach immediately after project: In total approx. 2000-3000 houses under service across NL
Energy systems and energy req.: Each of phase 1 (29) houses is equipped with 5KW/5-10kWh 2nd life EV batteries, a heat vessel of about 200l with a heat pump, a community battery 50kW/50kWh to be deployed by HESTIA. Phase 2 (17) houses will have all heat pumps, mixed setup of 3 batteries and one bigger community battery (150KW/kWh). 3 shared EVs (Nissan Leafs – 60kWh and Mercedes EV type TBD) with V2G and smart fast charging (via 150KW fast charger and battery for peak management).
Existing RES share and level of smart metering equipment available at the site: Approx. 8kWp of photovoltaic system installed on rooftops of the houses in main demo area (set of 46 houses).
Total RES share: 100% share for 46 houses and the Factory Zero advanced renovation demo house, and 0% for 50 neighbouring houses.
