Overview: We are undertaking trials to improve understanding of the economics of electrical energy storage. The learning gained will help improve cost effectiveness and provide a more sustainable, efficient and flexible way to reinforce networks.
There are several challenges preventing the adoption of energy storage across distribution networks. Storage used for a single application, such as network support, is typically inefficient. However, business models for maximising the value of storage are challenging to implement and evolution of regulatory frameworks is needed to better support adoption by DNOs.
This project is trialling how energy storage could be used to defer traditional network reinforcement and evaluating additional benefits that can be gained to maximise the value, and make storage a more cost-effective alternative. In order to achieve these additional benefits, the storage will be used for a range of other system-wide services, to benefit other electricity system participants, and test both the technical and commercial aspects of these applications.
The changing nature of generation and demand creates the need for increased flexibility in electricity networks and the need to recognise uncertainty in demand. Energy Storage can be a key enabler in providing this.
