Energy Cooperative

Good Parity is a non-profit cooperative legal entity established in 2020 and based in Spata, Attica. We license, deploy, and operate utility scale renewable projects exclusively for the self-consumption of our members, who include households and small businesses across the region. Our objective is to enable members to reduce their electricity bills, lower their CO2 footprint, and gain access to novel energy services built around flexible assets such as electric vehicle charging, heat pumps, and timed loads. We currently manage an active 100 kW photovoltaic installation in Spata that serves as the collective generation unit for the entire community.

Virtual Net Metering, defined under Greek Law 4513, allows a group of consumers to benefit from a shared renewable installation even when the panels are not on their own roof. The community’s production station does not need to be physically connected to any consumption point. Instead, the energy our 100 kW solar plant feeds into the grid is virtually allocated to participating members’ meters according to agreed percentages. For each meter, the allocated production offsets the energy consumed during the same billing period, which directly reduces the amount each member pays. This means members can be located anywhere served by the same supplier and still benefit from a single shared installation, without installing solar on their own property.

The community has real-time access to production data from two independent sources: the on-site monitoring system at our solar plant, and smart meter telemetry at the LV/MV substation provided by the national distribution system operator. Members have invested in 20 internet-connected EV chargers, 15 cloud-connected heat pumps, smart meters at every connection point, and a range of network-connected appliances such as smart washing machines. These data streams provide detailed insights into consumption and charging behaviour, enable advanced analytics, and form the basis for testing innovative energy management and optimisation models. Members who have not yet electrified transport or heating remain open to interventions, and the cooperative welcomes the testing and installation of new IoT devices and energy services.

Licensing of a 100 kWh on-site battery storage unit at the solar site is planned to initiate within 2026. This addition will complement the existing photovoltaic asset and enable the community to participate in frequency response markets, opening new value streams for the cooperative and its members. Combined with our existing real-time data infrastructure and the flexible assets already operating in member households, the battery turns Good Parity from a passive generator into an active grid services provider, contributing to the stability of the Greek electricity system while creating additional savings for our members.
