The purpose of this WP is to perform the preliminary work required before the development of the solution and its demonstration. It will mainly include the definition of the use-cases, the related requirements, the definition of specific relevant KPIs, the design of the architecture, the definition of the data handling and processing approach (needs, collection and consolidation), and the set-up of an interoperability-by-design framework. All this work will contribute to define the orientation of the subsequent work package, in particular the solution development (WP5, WP6 and WP7) and the solution demonstration (WP9 and WP10).

This WP is dedicated to the development and adaptation of technical energy system modelling tools needed for the project based on the development and evaluation of existing simulation and modelling software (widely used for energy system planning). It will lead to the creation of an island-scale economy-energy-environment modelling software to be used by partners and local authorities to explore low-carbon medium and long-term energy transition strategies. The WP will provide modelling software capturing both medium and long-term challenges and transitions (developed by E3M) as well as short-term forecasting of energy supply and demand and real-time operation of islands’ grids (led by HIVE and TUB).

The objective of this WP is to tailor the developed technical solutions to the local socio-economic context to ensure their successful adoption. The social, cultural and economic conditions on Mayotte will be studied and a technologically, economically and socially optimal energy system topology as well as decarbonisation pathway for the island will be developed. Beyond study and analysis, community activation and training activities will be carried out to include local communities to shape the energy transition on both consumer and producer sides.

This work package will ensure the commercial viability of the project and determine the business models and costs implication of the developed solutions by setting up an underlying market design and business models for the different market players, aligning the solutions with the local regulatory framework and providing policy and regulatory recommendations for an efficient market uptake in islands.

Due to the specific characteristics of geographical islands (weak or no mainland grid connection, low system inertia, high potential for variable renewables, high energy costs, etc.) the need for assessing flexibility requirements on islands is high.
The general objective of this WP is to design flexibility services that can be offered according to the market design of WP4, specifically tailored towards the reality of geographical islands. The involved partners will specifically aim at involving the flexibility from the demand and the supply side, both from residential and industrial customers for demand response as well as involve flexibility services by renewables. The following specific objectives can be derived:

• Develop a Virtual Power Plant to aggregate RE production of small units and facilitate their management
• Develop technologies and services (e.g. synthetic inertia) to ensure grid stability and power quality
• Develop tools for LEC such as collective self-consumption
• Investigate the opportunities, incentives, feasible assets, required tools and market design compatibility of residential demand response
• Investigate the opportunities, incentives, feasible assets, required tools and market design compatibility of industrial demand response

This WP aims at developing solutions able to provide additional flexibility to the grid thanks to networks’ synergies improvement and storage systems. Different vectors will be used:

• Smart management of EVs charging stations and V2G solutions
• Hybridization of charging stations and PV plants
• Complete storage systems based on batteries for frequency and voltage control
• Long-term storage based on hydrogen production

The overall objective of this work package is to deploy a utility-scale Control Platform, that will enable efficient management of various flexibilities aggregated by different systems throughout the island. Their utilization and monetization will be based on the island distribution grid operational needs and requirements. These will be achieved by defining data management and cybersecurity concepts, followed by deployments of aggregation toolbox for connection to local devices and systems, management and trading platform.

The main objective of WP8 is to supervise the integration across all solutions and innovative prototypes. Solutions, which are developed in WP5, 6 and 7, are integrated before being shipped to demonstration sites to be installed. WP8 uses defined overarching architecture from WP1, also taking into account specific requirements from the demonstration cases. The main objectives of WP8 are:

• Further define integrated system architecture from WP1
• Specify requirements towards interfaces between different building blocks
• Coordinate integration activities, linking WP5, WP6 and WP7 into integrated solution
• Implement testing procedure, consisting of unit testing, laboratory prototype testing, factory acceptance testing (FAT), site acceptance testing (SAT) and coordinate transfer of the system into real environment

WP8 will coordinate the deployment of complete system in the specific demonstration site environment. It will follow an equal top-down and bottom-up approach, taking into account both the functional capabilities of the developed solutions and the technical requirements and constraints of individual demonstration cases as instances of customised application of the integrated system. The final objective of WP8 is to enable smooth implementation and proper operation of systems installed within the demonstration WP9.

The objective of this WP is to physically implement all the solutions developed by the partners in the previous work packages on the islands of Mayotte. To this end, the main areas of focus for this specific work package will be the following:

• Deployment of the communication and control platform combined with innovative flexibility solutions
• Modelling and forecasting of the energy supply and demand
• Synergies between different energy networks especially the electrical grid and the transportation and mobility networks

Once the system will be integrated on the island, an important phase will be the collection and data analysis in order to determine the efficiency of the solution deployed compared to the simulations. The demonstration in Mayotte will allow to test the solutions and to improve them before duplicating them on the other islands. Then, it will make it possible to analyse the impacts and give some recommendations to optimise the use and the management of the system.

The objective of this WP is to provide expert support to selected follower islands for the elaboration of their medium and long-term energy transition plans, from the initial screening of their energy situation to the analysis of cost-efficient transition strategies and the development of a comprehensive scalability and replicability analysis. These plans will mainly address the energy systems and namely energy and electricity production, storage, flexibility options and energy efficiency of demand sectors (i.e. buildings, industries), transport issues, and the associated funding. The environmental, social and macro-economic assessments will also be integrated in the plans. In this framework, the project MAESHA will provide the islands common templates, user manual and methodological guidelines to define their initial state of play, set up territorial transition strategies and identify detailed strategic energy transition plans.

Communication around the project and dissemination of the solutions are key to the success to the project and the sustainability of the solutions developed. This work package focuses on the communication and dissemination of the results, aiming for a strong exploitation after the life of the project. Tailored activities will be planned to specifically reach the right target public. This work package details the work to be done to establish in detail the strategy as well as put it into practice. Moreover, detailed exploitation strategy will be developed to support the commercial interests of project partners. Last, synergies with other ongoing initiatives and projects will be made, with a particular focus on similar EU projects and initiatives.

The objective of this WP is the overall coordination, the administrative, financial and contractual management of the MAESHA project in order to ensure effective and efficient processes within the project and on the same time minimising (as much as possible) administrative overhead within all activities leading to the smooth realisation of MAESHA goals. Activities of the management include the coordination of technical activities and progress monitoring according to the work-plan, timely reporting and providing of other required information to the European Commission, coordination of the delivery of all reports and deliverables, organization of risk management and introduction of preventive actions and the organization of meetings of the General Assembly.
