The ever-increasing demand of energy in the society and the simultaneous need to provide that with renewable sources (with often intermittent character) calls for new solutions for balancing the demand and supply. Improved energy storage solutions offer a good option. The ongoing work in a European project, STORY, aims at demonstrating and evaluating innovative approaches for energy storage systems. The challenge is to find solutions, which are affordable, secure and ensure an increased percentage of self-supply. The project includes eight different demonstration cases each with different local or small-scale storage concepts and technologies, covering industrial and residential environments. These demonstrations feed into a large-scale impact assessment, with the aim to show the added value storage can bring for a flexible, secure and sustainable energy system. Each of the demonstrations brings a different technology, context or business case. STORY is now on its second year of action, and the results from the first year are available. These include definition of the main grid challenges to be addressed by storage solutions and specification of the requirements for the hardware and software elements that will be applied in the demonstrations and simulations. In parallel, during the first year, the installations on the demo sites were realised or preparatory work was conducted on the sites. The IT architecture was defined and optimized for each demonstration site. The partners also defined the measurement protocols and the related Key Performance Indicators. One significant result was the definition of a three level architecture for the control system. The grid simulation scenarios were chosen based on thorough studies of the local environment and availability of data. The definition of the business models started in co-operation with the other storage and smart grid projects funded in the same series of H2020 calls.
