The Nice Méridia energy community consists of a collective self-consumption project that gathers 5 original members with solar PV generation, electrochemical storage and electric vehicles. The project allows consumers and storage assets to consume exports from other community members. Self-consumption quantities are assessed every 30 minutes on an ex-post basis (at the end of each month) by the Distribution System Operator through smart meters, and locally consumed electricity is removed from the utility bill of the community members. Then, for each time slot of the previous month, a local energy market is implemented to determine the price and energy quantities exchanged. This market proposes a dynamic tariff that corresponds to the output of a double auction in which prosumers and consumers communicate their aggregator and supplier’s prices. Finally, the Nice méridia energy community has also implemented moral values that are implemented in the local energy communities through a priority that is given to some members of the community to purchase electricity.

Yann Rozier, Climate & Transition Project Manager at the University Côte d’Azur: “This energy community allows the community members to engage together and to think about the way we can better consume electricity together. It allows us to implement moral values that define us and that enables residentials to benefit from cheaper energy produced by tertiary buildings, especially during week-ends when there are no tertiary activities. We hope this energy community is developing as an example that can be replicated in other places in France, and maybe abroad.”
The key lessons learned are about trust. An energy community cannot be successful if trust is not the backbone of the initiative. Therefore, it is strongly recommended to gain the trust of the members when proposing to join an energy community. This can be done by showing examples, by being transparent and by proposing simulations that demonstrate the benefits and difficulties that will arise from the energy community. Second, it was experienced that members want to build a community that actually represents their own values. As a result, an energy community should be built for and by the members, based on local considerations and specificities, and it is therefore necessary to propose economic mechanisms (such as market clearing algorithms or energy dispatch approaches) that reflect these values, such as giving priority to low income or fuel poor members. Finally, regular communication should be proposed to the community members. This enables them to feel involved in the community, and to trust the directions that are taken and to prevent any disagreements.
What outcomes are anticipated from the pilot? This pilot aims to showcase the possibility to have an advanced local energy community within the current legal framework in France. This will also result in a bill reduction for the consumers, and an increase in revenues for the producers. This energy community aims to pave the way for future energy communities with local energy markets.
What outcomes were delivered by the pilot? At this stage, the pilot is still on-going. Algorithms have been designed, members have actively engaged in the community, and financial trades will happen shortly.
