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:

• There are now additional references to cyber security measures
  
• Type-testing of equipment can now be carried out for families of similar units using the same control
  
• Requirements for the accuracy, and other specifications, of instrument transformers and meters used for fault recording and
  
• New considerations for systems designed to normally operate as an independent island, but capable of paralleling with the DNO's network
  
• Changes and new tests to ensure stability under no-fault conditions
  
• Changes to the information required and the format of standard application forms
  

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.

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:

• Private 33kV network engineering and consultancy
• HV switchboard automation and control scheme design
• LV auxiliary scheme design
• Switchboard design reviews
• Construction documentation and drawings
• Engineering support and consultancy
• As built / in-progress installation surveys and site meetings

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.

See our Careers page for more information

We would also like to take this opportunity to thank you for your custom over the last year, and we look forward to working with you again in 2014.

Finally, on behalf of CEE, I would like to wish you a very Merry Christmas and a happy and prosperous New Year.

Cooper Energy Engineering is proud to announce that it is "walking the talk" and has taken its first step towards an environmental management accreditation programme. CEE has pledged to develop its Environmental Policy, and to put in place measures to reduce our carobon footprint in our actions and our designs.

We're also offering our services to the GreenerNorthants network, helping local businesses develop their low-carbon strategies.
