DEVELOPMENT OF ELECTRICAL ENERGY STORAGE IN THE EU INTRODUCTION STORAGE – FUNCTION, PLACE, TECHNOLOGY BUSINESS MODELS CONCLUSIONS

 In order to meet European Union climate and energy policy targets, the energy sector must undergo substantial structural changes.  Electricity will play a crucial role in this transformation.  Before stating categorically that more storage should be introduced, it is important to have a comprehensive understanding of the eventual functions that electricity storage has to fulfil, together with other grid-, generation-, and demand side assets. INTRODUCTION

 What the future power system needs is not electricity storage as such, but rather well-adapted system and market architectures. Electricity storage should be considered as one of the many ways to provide various services to the system and it be seen in the broader EU energy context, taking into account possible interactions between different types of energy storage. INTRODUCTION

 Assuming the need for specific storage facilities, the search for workable business models should start within the current market design and regulatory context, investigating how to facilitate cost-effective and market-based storage deployment and operation. However, electricity markets need to be redesigned and therefore storage must be seen in this long- term perspective. INTRODUCTION

BUSINESS MODELS

By focusing on only one specific application, electricity storage typically cannot reach profitability in the current market context. Today’s challenge are: a)how to aggregate multiple services and to maximize multi-income streams; b)how to overcome existing market design / regulatory obstacles.

CONCLUSIONS 1)How to coordinate the provision of multiple services ? 2)How to facilitate market-based storage deployment within the current market structures, while 3)avoiding stranded costs / misallocation of resources ? 4)How to handle sytorage within a new (2020 / 2050) market design and regulatory framework ?
