StoRES foresees the development of an optimal policy for the effective integration of photovoltaics (PV) and energy storage systems (ESS) via testing smart solutions in 5 MED islands and rural areas. The challenge is to achieve high PV penetration in their energy mix through solving all market/technical/grid/tariff issues without compromising grid stability or security of supply.
The objective is to boost PV self-consumption in the MED through an optimal storage solution.The approach is to test PV storage solutions for the consumer in different pilot sites taking into account local parameters for optimization and using efficiency measures. StoRES is expected to change the current situation concerning grid reliability with higher RES deployment in islands/rural areas giving a cost-effective option to the public on more affordable and sustainable energy supply. Public authorities will be mobilized leading to their engagement in sustainable energy strategy implementation in their jurisdictions with a truly long-term vision in mind.The MED, as the natural place for PV and where grid parity is a reality, has the opportunity to pioneer in testing such technologies in real time with authorities ready to contribute.This endeavour will increase socio-economic competitiveness of regions involved;most importantly will have an international impact as new knowledge for optimum PV-ESS interoperability is transferred to a broader geographical context where grid parity has not reached yet.
StoRES propose le développement d’une politique optimale pour l’intégration efficace du photovoltaïque (PV) et des systèmes de stockage, en testant des solutions intégrées dans 5 îles MED et territoires ruraux. Le défi est d’augmenter la part du PV dans le mix énergétique de ces territoires en résolvant les enjeux techniques, tarifaires et de réseau sans compromettre la stabilité des réseaux ni la sécurité d’approvisionnement.
L’objectif est d’accroître l’auto-consommation à travers une solution de stockage optimale. Des solutions de stockage de l’énergie PV seront testées prenant en compte les profils des consommateurs pour une optimisation de l’efficacité énergétique. StoRES permettra d’améliorer la fiabilité des réseaux par un déploiement accru des ENR dans les îles/territoires ruraux, donnant au consommateur une solution économiquement rentable pour une énergie durable. Les pouvoirs publics seront mobilisés dans le cadre de leur politique en matière d’énergie durable en ayant une vraie vision à long terme.
La zone MED, prédisposée pour le PV et où la parité réseau est une réalité, a l’opportunité d’être précurseur pour tester ces technologies en s’appuyant sur des collectivités prêtes à s’investir. Cette initiative améliorera la compétitivité socio-économique des régions impliquées et aura notamment un impact international puisque la connaissance acquise sera transférée aux régions européennes où la parité réseau n’est pas encore atteinte.
Expected Results (EN):
1 Development and validation of an improved self-consumption policy through the utilization of distributed RES in combination with ESS : Through the project a new, smart, easily administrated and simple self-consumption policy is expected to be developed and validated which can be optimally implemented throughout the MED region. The new policy will allow the introduction of energy storage units that will fine tune and optimise the current policies that are based on the different specificities of each region. The new policy can reduce energy poverty and increase the energy autonomy and efficiency of islands and rural areas.
This result will contribute to the defined programme result indicator by enhancing PV penetration into the energy mix of the regions participating through effective integration of storage and PV.1 Development and validation of an improved self-consumption policy through the utilization of distributed RES in combination with ESS : Through the project a new, smart, easily administrated and simple self-consumption policy is expected to be developed and validated which can be optimally implemented throughout the MED region.

This result will contribute to the defined programme result indicator by enhancing PV penetration into the energy mix of the regions participating through effective integration of storage and PV.2 Pilot demonstration of integrated PV and ES systems into the energy mix of rural areas and islands : The pilot implementations of this project will be the first real examples of integrated RES and ESS into the energy mix of the Mediterranean basin. The pilot sites will provide significant lessons to all energy stakeholders and will have a multiplier effect. DSOs will have the opportunity to examine the gains from implementing ESS into the energy mix and they will allow further penetration of RES into the grid. Additionally, new policy schemes arise from these pilot demonstrations and the policy makers will have the opportunity to introduce new policies that will attract the consumers therefore, increasing the implementations of domestic RES implementations. Moreover, the pilot sites will provide valuable lessons learned regarding the optimal integration of these systems into the energy gird and possible problems and their troubleshooting.3 Identifying and addressing all technical and regulatory requirements for the introduction of ESS into the energy mix : StoRES is expected to contribute to addressing all the technical and regulatory requirements concerning the increase of PV share into the energy mix through integration of PV and ESS. This will be achieved by starting with a feasibility study in the first phase of the project which will be carried out to identify the state of the art of PV and ESS in the MED region in terms of financial, technological, policy-related issues, etc. This study will be the basis for the test phase of the self-consumption policy, energy storage systems and demand side management mechanisms. It will also identify the barriers for the introduction of ESS into the electrical grid revealing the technical and regulatory requirements needed to overcome them. This will cover all participating countries/regions thus addressing the problems in the whole of the Mediterranean region.
This result will contribute to the defined programme result indicator by removing all barriers and dealing with the main requirements (technical, regulatory) for introducing ESS to the electricity grid of participating countries, which will improve the penetration of PV and thus the overall share of RES in their energy mix.4 Evaluation of the ESS contribution to solving intermittent RES shortcomings & increasing the level of possible RES penetration into the energy mix : The project aims at the increased share of RES (and specifically PV) into the energy mix by pushing the current limits of RES in these areas from 25 - 30 % to more than 50 %. This is expected to be achieved by the introduction of ESS.
Through the activities of the project, an evaluation of the actual contribution of ESS to solving the transnational problem of intermittency of RES, which limits penetration into the energy mix, will be achieved. It is expected that the introduction of ESS can be beneficial to both the grid operator and the prosumers. The former will benefit as fluctuations and power ramps of the energy produced from RES can be addressed by storage thus safeguarding efficiency, security and reliability of the grid; the latter group will benefit as new and improved self-consumption policies can be introduced that will allow a more efficient use of energy and more effective demand side management.
This result contributes to the project result indicator as the aforementioned anticipated improvements in grid operation and demand side efficiencies will allow higher levels of RES penetration in the energy mix at an overall lower system cost which can also lead to lower costs to the end users. The prosumers are expected to be allowed to operate their systems with less system charge reflecting the lower costs incurred to the system.5 Integration of ESS in the energy mix of participating regions. : The ESS are going to be implemented at the residential and local (social) level in a number of pilot countries. This will allow the investigation of different policy scenarios for each type of storage i.e. residential or social and for different regional parameters (grid, tariffs, policies, local resource). The benefits through the use of storage to the grid of rural areas and islands will be investigated. It is expected that the ESS will address all the shortcomings regarding the intermittent nature of PV energy and will support the smooth operation of the grid thus preserving the security of supply to all users. Thus, the energy mix strategies and plans for increasing the share of RES in the MED region are expected to be enhanced, facilitating higher penetration of RES to more than 50%. This suggests effective contribution to the project result indicator.6 Enhance Demand Side Management (DSM) possibilities : Through the joint self-consumption policy developed enhanced active DSM mechanisms will be pursued. The mechanisms can be either price- or incentive- based DSM. The price-based DSM can be real time pricing, critical peak pricing, ToU pricing, etc. The incentive-based DSM includes economic incentives that are not included in the electricity tariffs. Through the DSM programs the energy produced from the PV systems and stored into the ESS will be optimally used in order to benefit the grid and the end users of each participating area. Optimal DSM in each pilot and the broader region that the project outcomes will be transferred to/replicated means more efficient use of renewable energy, more savings for the prosumers leading to better promotion for RES to key stakeholders and the general public and thus an impact on the share of RES in the energy mix of MED islands and rural regions (contribution to project result indicator).7 Key stakeholders become more engaged in the development, implementation and monitoring of sustainable energy policies and plans : Key stakeholders (public authorities, policy makers, DSOs, etc.) in participating regions acquire, through the project and particularly the pilot and transfer activities, the skills and knowledge necessary for the effective implementation of sustainable energy strategies and measures in their regions. Public actors are thus empowered to facilitate the contribution of further local RES in the energy mix of each partner country, thus contributing significantly to the project's chosen result indicator.8 Online storage solution tool : The project is expected to result to a simple, user-friendly online storage solution optimization tool for each pilot region with the possibility of expanding it to be used in a broader context and a broader geographical region (including the country followers). The tool will be used for the assessment of different self-consumption policies and the proper sizing of an ESS. This online tool will be made available to the end-user, policy makers and DSOs who can intervene and have an impact in local/regional/national energy strategies and policies thus contribute to an increase in the share of renewable energy in the energy mix of their regions (contribution to the project result indicator).9 Rollout of integrated PV-storage solution to a broader MED region and beyond : The final activities of StoRES include the roll-out of the generated PV-storage solution which will be based on the pilot implementation outcomes as well as the simulations from the follower countries (Slovenia, France). The solution will also result in guidelines for optimum integration of RES and storage to key stakeholders in the participating regions (islands and rural areas) but also within the broader MED and Europe with the aim of influencing regional/national strategies and plans for higher penetration of RES in their energy mix (contribution to project result indicator).1 :
