Welcome to our website detailing our proposals for Sunnica Energy Farm



July 2022 – targeted consultation on change to the Order limits and Abnormal Indivisible Load (AIL) vehicle tracking

In preparation for submitting our changes application to the Examining Authority, we have undertaken additional swept path analysis (vehicle tracking) to ensure that the electrical infrastructure required under Option 3 can be safely transported to Sunnica West Site A, Sunnica East Site A and Sunnica East Site B.  To ensure a robust assessment, the tracking has also been redone for Burwell National Grid Substation Extension Option 2 using a worst-case vehicle that has been utilised for the Option 3 solution.

This analysis has indicated that there will be an area where an Abnormal Indivisible Load (AIL) delivery required to transport the substation and transformer to Sunnica East Site A during construction will oversail the highway boundary while turning. This area is shown in the plan available to download on the right of this page and forms the junction between the B1102 Mildenhall Road and an unnamed road immediately to the east of Freckenham.

For this journey to be made safely, the existing fence and gate area at this junction will need to be temporarily realigned. We are therefore proposing that this area is added to the Order limits and to be subject to a power of temporary possession to allow this work to be carried out.

We are consulting on this change to the Order limits and the information outlined in the AIL tracking report (also available for download from the right-hand side of this page) only between Wednesday 27 July 2022 and Wednesday 24 August 2022.

This is a targeted consultation that Sunnica is undertaking with the following people and organisations:

  • Persons with an interest in the over-sail land identified through Sunnica’s diligent inquiries
  • The local highways authorities and National Highways
  • West Suffolk Council and East Cambridgeshire District Council
  • Local parish councils

Any response to the consultation must be made in writing to Sunnica on or before 23:59 on 24 August 2022 by one of the following means:

Any comments received will be analysed by Sunnica and any of its appointed agents. Copies may be made available in due course to the Planning Inspectorate and other relevant statutory authorities so that feedback can be considered as part of the process. Comments received that do not relate to the proposed change to the Order limits or the information outlined in the AIL tracking report will be disregarded.

Following the end of the consultation, Sunnica will review the responses that it has received and before submitting a changes application to the Examining Authority. This application will also include the changes on which Sunnica has already consulted. Should the changes application be accepted by the Examining Authority, it will be available to review and comment on as part of the Examination process.

Consultation on proposed changes (June-July 2022)

In November 2021, Sunnica Ltd applied for development consent to build Sunnica Energy Farm (‘the Scheme’). The Planning Inspectorate accepted the Sunnica Energy Farm Development Consent Order (DCO) application for Examination on 16 December 2021.

We are now seeking to make some changes to the proposals for connecting to the national electricity transmission system included in our application for a Development Consent Order.

Since submitting our DCO application we have received updated information from National Grid Electricity Transmission (NGET) about connecting the Scheme to the national electricity transmission system at the Burwell National Grid substation. We are therefore proposing to change the technical options for our grid connection included in our DCO application to take account of this new information

Before we submit our application to the Planning Inspectorate to make these changes, we are consulting on these changes between 6 June 2022 and 6 July 2022.

Our consultation booklet provides further information about the proposed changes and how to take part in the consultation.

If you would like to submit your views to Sunnica Ltd, you must do so in writing by one of the following means:

  • By email to info@sunnica.co.uk
  • By post to: FAO Sunnica Energy Farm, Freepost SEC NEWGATE UK LOCAL

Your response must be received by 23:59 on Wednesday 6 July 2022.

Any elements of responses that refer to aspects of the Scheme that are unrelated to the proposed changes will be disregarded by the project team.

We held public exhibitions for our changes consultation on Wednesday 22 June at Mandeville Hall, Burwell and on Thursday 23 June at Chippenham Village Hall.

At these exhibitions we presented illustrations of what the revised substation layouts could look like.

These illustrations are available to view below:

We have prepared an explainer document to assist with understanding some of the terms referred to in the changes consultation booklet. This can be viewed here.

St Margaret’s Church, Chippenham has advised us that it is no longer able to hold copies of the changes consultation booklet. Copies remain available on request using the contact details below. Copies of the booklet are also now available at the Red Lodge Sports Pavilion, Hundred Acre Way, Red Lodge, IP28 8FQ.

The proposed Sunnica Energy Farm would be located across four sites in East Cambridgeshire and West Suffolk. If constructed, it would connect to the national electricity grid at the Burwell National Grid Substation.

The project is classified as a Nationally Significant Infrastructure Project (NSIP) by the Planning Act 2008 because it would have a generating capacity in excess of 50MW.

Sunnica Energy Farm would include both solar photovoltaic (PV) and battery energy storage (BESS) infrastructure. The four solar sites would be connected to each other and the Burwell National Grid Substation by an underground cable and would allow for the generation, storage, import, and export of electricity.

Our proposals represent an important opportunity to help meet the urgent national need for new, renewable, means of energy generation.

We submitted our DCO application to the Planning Inspectorate on 18 November 2021. The Planning Inspectorate accepted the application on 16 December 2021.

Prior to submitting our DCO application, we carried out two rounds of public consultation, including a statutory consultation between 22 September 2020 and 18 December 2020.

About us

Sunnica Energy Farm is being proposed by Sunnica Limited – a joint venture between two established solar developers, Tribus Energy and PS Renewables. Together the Scheme partners have assembled an experienced team with a strong track record of delivering high quality solar and energy storage developments.
