Practical Issues with Electrical Energy Storage Projects

Abstract

Mr. Haike van de Vegte sketches the global developments, specific European developments as well specifically the Dutch storage sector, the National Action plan Energy Storage published by Energy Storage NL with assistance of DNV GL and storage projects of various sizes and types. Not surprisingly, storage for electric mobility has already been implemented at many sites, combining solar-PV and storage at fast-charging sites. Next to that, several demonstration projects have been developed, showing the viability of storage as a concept. But perhaps more interestingly, several commercially viable projects have recently popped up, such as the CrowdNett initiative, the storage system at the Amsterdam Arena, the 10MW facility of AES in Vlissingen, a community storage system in Etten-Leur and several storage systems at farms with renewable energy production. He will describe the costs for (electricity) storage are declining rapidly, and how electricity prices are under pressure on the one hand, and balancing prices are increasing. We see the perception of storage changing from a complex and expensive asset to an essential building block for the energy transition to a more sustainable society. As a call-to-action, he will explain which business models are currently interesting - such as the Frequency Control Reserve as well as the Frequency Restoration Reserve - and how "new values" such as grid investment deferral need to be disclosed by the network operators in order to stack multiple values. An important new business model is emerging in and outside of the Netherlands, where it is interesting for solar- and wind developers to add storage to their systems, in order to increase the overall business case. Additionally, he will mention the need for Independent Engineering and Bankability studies for energy storage project, in order to speed up storage integration into the grid. He also explains how the GRIDSTOR Recommended Practice can assist project developers and investors alike to identify and mitigate technology risks.
