Fast Track Application Process for EREC G59 Energy Storage Devices

Fast Track Application Process for EREC G59 Energy Storage Devices – Guidelines June 2018

The industry is predicting a significant upturn in LV connected small scale Energy Storage.  In GB Engineering Recommendation (EREC) G83 and EREC G59 facilitate the connection of all generation, including Energy Storage but some Manufacturers and Installers consider that the current requirements of these ERECs can sometimes be seen as a barrier in terms of application timescales and the potential high costs imposed for witness testing small scale domestic Energy Storage schemes.

This has been further highlighted as a result of the IET Code of Practice for Energy Storage (CoP). Publication of the CoP was stalled until a mutual resolution to these obstacles could be found. Both BEIS and Ofgem voiced their concerns regarding the aforementioned and whilst they are understanding of the legislative/regulatory issues that currently exist and the need for visibility of what is connected to the networks they were keen that the industry worked together in finding both a suitable short-term solution and initiating work on a longer term resolution.

The Guaranteed Standards of Performance (GSoP) timescales for providing an LV generation quote/response are currently 45 days and whilst it is uncommon for a small LV connected scheme to be witness tested there was evidence nationally where schemes as small as 1kW had the requirement for a witness test included within the customer’s quotation. In addition to the inconsistencies that exist around the requirements for witness testing there was also the uncertainty as to when to apply the requirement for an Export Limitation Scheme (ELS).

To address the aforementioned perceived barriers in the short-term, these guidelines have been developed to set out a process change for small scale schemes. It is anticipated that by considering the application of this methodology the customer experience will be improved and the workload on DNOs should be greatly reduced.
