  • We collaborated with Regen to develop an approach to model the future growth and operation of storage assets to better understand how these assets are likely to be used, and their ‘mode of operation’; including their typical profile of charge and discharge.

    We consulted with industry to establish whether the analysis and definitions of the underlying business models, project specifications and operating modes, are appropriate and reflect how the sector views the likely deployment and operating behaviour of storage.

    In undertaking this consultation, we were seeking to understand:

    • The potential scale of growth of energy storage within its distribution networks
    • The type of energy storage assets/projects that are likely to be deployed and their business models
    • The typical operating behaviour of storage assets, how they are likely to be used and their typical daily mode(s) of operation

    We had a positive response to this consultation, receiving 27 submissions from a broad range of organisations from across the industry. These responses provided a breadth of feedback and useful insights around the growth,

    technology, technical specification and operation of energy storage assets. One striking result from the consultation was that 96% of respondents felt that storage would predominantly be connected on the distribution network, meaning that WPD (and other DNO’s) will need to adapt to meet the expected growth in storage capacity in the future.

    As a result of the feedback we have received through this consultation, the report concludes with an outline of some of the specific areas where we have adjusted our network modelling assumptions as well as some key principles that we wish to implement, to ensure the benefits of energy storage can be realised on its network.
