STORY does not provide a single roll out scenario due to multiple reasons. First, solutions, other than storage, are currently being developed and tested to tackle the grid challenges such as power quality, security of supply, line congestion management, voltage control and reserve provision. Second, providing a single roll-out solution assumes either a fixed policy & regulatory framework or will provide a list of required changes to policy and regulation. Third, markets are shaped where opportunities are created and will naturally form if they are tempting enough. Projects do not shape markets, but STORY will show the opportunities.
That is what STORY is about: not about predicting the future, but about demonstrating where storage could be used in what way. STORY gives an indication about the costs, the benefits, and especially how sensitive they are to the main technology, market, policy, and regulatory factors that are uncertain today…. This way stakeholders get a better idea of how the future of energy storage might look like, especially if STORY finds that depending on where storage is deployed (and the type of storage deployed in that location) the business case might depend less or more on specific uncertain factors than on others.
STORY aims to show the added value storage in the low and medium voltage grid can bring. 8 demonstrations are set up to feed knowledge into the further analysis on large scale impact assessment and on market models, policy & regulation. The results of this projects are summarized in a limited number of reports, but clearly focused on deployment.
The 8 demonstrations are located in 5 different member states (Belgium, Spain, Ireland, Germany and Slovenia) and cover industrial and residential environments, from building scale to district scale. The demonstrations deliver input on technological performance, stakeholder engagement and acceptance and on the overall process of storage integration. An in depth practice oriented analysis on grid challenges, hardware requirements and ICT delivers insights to the demonstrations and builds on the demonstrations to deliver input towards deployment and impact analysis.
The 8 demonstrations feed into the large scale impact assessment, where an answer is formulated to the question “What if a large amount of storage is integrated in the distribution grid?” The analysis includes considering challenges to the grid infrastructure, required or deferred investments, but just as well the impact on the integration of local decentralized and large scale centralized RES. To understand the value of storage in the light of the evolutions in smart grids, STORY takes into account the experience and knowledge gained in the project demonstrations and extrapolation analysis, combined with the expertise of the STORY-team, the advisory board and cooperation with the other LCE6-10 projects. STORY uses that to derive a market, policy and regulatory framework that considers the impact and potential of a market driven or a regulated roll-out of storage. The strong cooperation with a variety of experts and stakeholders ensures that the outcome will not be a STORY output, but an output built on a broad foundation.
STORY is not about predicting the future but about showing impacts and opportunities. Therefore STORY will apply price scenarios for an impact analysis rather than use a market model that predicts prices to evaluate the viability of a certain business case.
Projects do not open new markets, but with STORY the potential of these markets is shown. The clear and transparent view, the STORY’s foundations, will consequently provide the market with the background and understanding necessary for rolling out storage in the distribution grid. This broad approach is also an essential aspect in the dissemination and deployment. STORY’s demonstrations are wide-covering, but not all aspects of storage integration in smart grids can be added into a single project. Outside of the conventional activities, a strong emphasis is on bringing joint communication with all LCE6-10 projects and delivering deployment and replication oriented results that are based on the joint experience of all storage and smart grids projects in the LCE6-10 call, i.e. of all stories.
