3. Results
3.1. Case 1. Analysis of Energy Communities in Greece
- Non-profit Ecs: do not share the surplus use among their members, and
- For-profit Ecs: share the surplus use among their members.
- Forms of organisation: dispersed within the same administrative region. However, there is a proximity requirement that at least 50% of all members must live or own a property in the same region. In addition, they are categorised as non-profit and for-profit [25]. There are no data available about the share of non-profit and for-profit Ecs, but the vast majority are for-profit.
- Power grid owner: Ecs are not the owners of the power grid. Each member may hold, in addition to the mandatory shares, one or more optional shares, with a maximum participation limit of 20% in the cooperative capital, except for the local authorities, who can participate with a maximum of 50% (areas with population <3100 inhabitants), and 40% for the rest.
- Public economic support: they have not received any economic public support. However, public administrations can be members of Ecs.
- Size of the system per project: it ranges from 29.68 to 1000 kW. The average size is 697 kW.
- RES electricity covered by Ecs: the total installed power capacity equals 613 MW (as of May 2022).
- Heat/cooling covered by Ecs: In 2021, the photovoltaics owned by Ecs represented 12.7% of the total installed PV capacity in Greece. The share of heat/cooling covered by Ecs is only 0.1%.
3.2. Case 2. Analysis of Energy Communities in Italy
- Forms of organisation: Energy can be shared within the same market zone, but to access the incentives, customers must be connected to the same primary substation. Since the Ministry published the specific implementing decree of the DL199 of 8 November 2021, members had to be connected to the same secondary substation to access the incentives. In 2023, there are still delays in the publication of the regulation and financial support measures [35].
- Power grid owner: production facilities must be available to the community, not necessarily owned.
- Public economic support: Italy’s National Recovery and Resilience Plan 2021 (PNRR) [36] specifies the financial resources reserved for the energy transition, with at least 37% of its total resources to be earmarked for this purpose; namely EUR 2.2 billion in investment for the promotion of renewable energies through support to Ecs and collective self-production structures (Component 2).
- Use of technology: Ecs often use solar or hydroelectric power.
- Size of the system per project: detailed information can be found in the Orange Book [37].
- RES electricity covered by Ecs: the average size of the photovoltaic system is between 20–50 kWp. Ecs are using also mini-hydro.
- Heat/cooling covered by Ecs: Depending on the type of facility, it could be designed to cover 100% of the heating and cooling needs of the members. When more renewable energy is generated than is demanded by the HVAC/DHW systems, it is used to meet other energy needs.
- Governance activated by experimentation with new energy-saving technologies in residential structures: this initial model can then be extended to the condominium and surrounding neighbourhood, giving back a greater degree of organisation to the actors or active volunteers who initiated the ideas.
- Governance based on a collective initiative: at a later stage, governance can lead to the creation of a collective body, a cooperative, a living lab, or a community association for governance itself. The roles of organisations already present in the area can be integrated with the governance principles adopted by the community. As a result, a governance entity is created or an existing one is renewed by integrating its objectives with those of a community governance entity.
3.3. Case 3. Analysis of Energy Communities in Spain
- Top-down strategies: agreement between large energy companies and municipalities for creating shared self-consumption (mainly, using photovoltaic technology). Members pay a monthly fee in exchange for a percentage reduction in their electricity bills and have lower risks and therefore more financial backing (e.g., the agreement between CaixaBank and Edinor for implementing a business model).
- Bottom-up model: partners create the EC and try to bring in new entities such as municipalities or surrounding companies. They tend to have greater initial uncertainty and, therefore, less financial backing (e.g., the agreement between Fiare BancaEtica and Som Energia).
- Forms of organisation: Most of the initiatives are starting their activity on the basis of RD 244, which allows them to be configured as shared electricity self-consumption entities [26]. Under this legislation, they can create a collective installation with an anti-discharge mechanism that prevents the introduction of non-consumed renewable energy into the power grid, or they can be constituted as a subject that feeds surplus energy into the electricity system. In the second case, economic compensation will only be provided if the requirements set out in the legislation (RD 244) are met, i.e., that the renewable generation system does not exceed 100 kW of installed power. Their most common activity is sharing electricity self-consumption, so their installations are configured according to RD 244.
- Power grid owner: some Ecs have their own distribution network, but most of the installations use the distribution network for exchanging electricity between their users.
- Public economic support: Even though some Ecs have been created under European projects, investment grants vary between 30 and 60% (CE IMPLEMENTA program—idea) depending on the technology mix used (electric, thermal, electric mobility measures, energy efficiency solutions, demand-side management improvement measures).
- Use of technology: Although a couple of ECs also share thermal energy through Biomass District Heating, most of the initiatives put their faith in the self-consumption of electricity generated by solar photovoltaic installations to start their activity.
- Size of the system per project: they can have one or more generation points with a total capacity between 16 and 125 kWp. The power-per-user ratio varies between 0.5 and 1.5 kWp.
- RES electricity covered by ECs: In most cases, it is still too early to tell, since they have only been in operation for a fleeting time, but estimates foresee coverage ratios of between 40 and 60%. That is, with these initiatives, approximately half of the energy consumed by the ECs is covered by renewable production in the surrounding area.
- Heat/cooling covered by ECs: In the case of thermal energy, they provide heating and DHW but not cooling. ECs cover all the thermal needs of these users.
