The HARMONISE project includes altogether 5 pilot sites. The 5 th pilot is a virtual Super
Nova grid while the rest are physical districts located in Estonia, Spain, Italy, and Switzerland.
Avala District, Estonia
The Avala District is a business quarter located in Tallinn, Estonia. It consists of 2 large office
buildings, a parking house, and a department store. The district includes several EV charging
stations, a battery, ground-source heat pumps, and on the roof of the department store
currently the largest rooftop solar park in Estonia, largest PV plant in Tallinn. Locating in a
cold Nordic climate, the district faces long cold winters and moderate summers. With
reduced sunlight hours the winter production of the PVs is minimal, however, the summer
production poses challenges to the grid.The district is used by approx. 1500 people. The
Avala District relies on a mix of renewable energy sources, with a primary focus on solar
energy. A photovoltaic system with a maximum capacity of 1400 kW is installed on the roof
of the department store (H3), serving as a central electricity contributor.
#1
Pozo Lorente, Spain
This pilot demo site is located in Pozo Lorente, a small village with 400 small buildings and
single-family houses and a rural typology in the province of Albacete, Spain. The village
experiences a continental climate, characterized by hot summers and cold winters.
According to the population census, there are 386 people living there permanently
(including winter), with a high degree of seasonality, which increases the population
significantly in summer (reaching up to 4 times higher than during the rest of the year). The
main economic activities of the area are tourism, agriculture and livestock.
#2
Vallevignale, Italy
The Italian demo is located in the central part of the Italian peninsula, in Abruzzo region. The
site is placed in Vallevignale, a small town in the municipality of Notaresco, Teramo.
Vallevignale has 58 inhabitants, and it is located near to the Italian coasts close to the
Adriatic Sea. Vallevignale has a full Mediterranean climate, and the whole area is
characterized by temperate summers and winter seasons: the average temperatures in
august are 29-19 °C while in January are 11-3°C; the average precipitation varies from 60mm
per month in August to 120 mm per month inApril. The average Direct Normal Irradiation
(DNI) is around 1600 kWh/m 2 , while the photovoltaic potential is around 1500 kWh/kW p .
#3
AIC, Switzerland
Tesserete is the energy community district under the municipality of Capriasca, which is in
turn under the district of Lugano in the canton of Ticino in Switzerland. Capriasca has an area
of 36.35 km2. The Arena Innovation Community includes residential and commercial
buildings, such as single- family homes, multi-family dwellings, and condominiums. Assets in
AIC are clustered in three main groups – Buildings, Storages, and Assets.

HARMONISE Super Nova Grid
Super Nova Grid represents a virtual simulation pilot designed to illustrate the integration of
a advanced Pan-European energy network. This conceptual framework envisions leveraging
energy from all physical HARMONISE pilots to support a hypothetical unified Positive Energy
District (PED) or community. The virtual PED may incorporate a diverse array of assets,
including energy demand from Spanish buildings, storage facilities in Italy and Switzerland,
and renewable energy generation from Estonia. These elements are combined into a
singular system to effectively manage demand, optimize storage loads, and fully utilize
renewable energy sources (RES).
