The ENA document EREC G99/1 governing the connection of embedded generators to the (other than domestic and similar projects <16A/phase) has been revised, with a new version coming into force at the beginning of September 2021.
The latest version can be freely downloaded from the Distribution Code website (or you can click here for a direct link to EREC G99/1-8)
The revision notes list this as a "minor technical modification". However, there are some noteworthy changes that affect the solar and energy storage projects we're involved in:
The previous EREC G99/1-7 was only published in August. It, too had some interesting changes, notably forewarning in the Foreword that energy storage units are likely to be required to export, or at least stop importing, during underfrequency events; a technical description of what this might look like (currently options) are included. The Foreword suggests that it'll be confirmed and become a mandatory requirement in 2022.
We're proud to announce that one of our key project of the last year, a 25MW energy storage facility near Taunton, is now operational.
The investor in the scheme is South Somerset District Council, with Opium Power as developer/project management and BSR completing the works as main contractor.
The project is a 33kV 25MW energy storage scheme with a BYD containerised solution. It is optimised to provide grid services to National Grid, including frequency response and balancing services. However, through the involvement of the aggregator Kiwi Power it is able to be flexible offer a full range of services to support the transition to a low carbon electricity network.
More information about the project is on the Client's press release.
CEE provided design and engineering services to the EPC / main contractor during a major works programme, starting in Summer 2019. We supplied the lead on electrical design for our customer, including:
Prior to the buld programme, CEE had also provided engineering services to the ICP for the DNO connection, including switchboard specification, cable design and managing the contestable works approvals process with WPD.
We look forward to working with our customers to deliver proposed extension works to bring the site up to 30MW. Indeed, despite Covid-19, it appears that 2020 will be a growth year for our utility scale new-build design projects, with a growing pipeline of solar and storage sites.
We hope all of our clients are staying healthy during this troubling time. We recently published the following notice to our regular clients regarding the measures CEE is undertaking to minimise the risk to the public.
Owing to recent Government advice:
We apologise in advance for an inconvenience this will cause, but hope that you understand given the unprecedented nature of the matter.
