Decision details

The Halewick Lane Battery Storage project proposes the re-development of the previously derelict North Sompting Waste Management Site into an income generating battery storage project.

Following a review of the proposed project previously approved by the Cabinet Member for Environment and Climate Change (decision ENV06 (20/21) refers) it has been determined that revisions to the scheme by using a first-life battery option would generate increased revenue from the project.

The Cabinet Member for Environment and Climate Change will therefore be asked to approve the changes to the Halewick Lane Battery Storage Project and the Halewick Lane site with focus on the following key items:

(1)The change to the previous system design to the purchasing of a first-life utility-scale battery system.

(2)The proposal to maximise the available export capacity from the site by increasing the battery size to 24 MW.

(3)The increase in capital expenditure allocated to the project to complete the site in a single phase.

(4)The launch of a procurement for the revised scheme and delegation of authority to the Director of Environment and Public Protection, at the conclusion of the procurement process, to award the design and build contract for the scheme.

The Cabinet Member for Environment and Climate Change, for the Halewick Lane, Sompting, Battery Storage Project, has –

1)    Approved a re-procurement process increasing the system size to 24MW with the specification of first life batteries as set out in section 2 of the report

2)    Approved the increase of £12.063m to give a total budget of £23.600m, funded from the Your Energy Sussex – Solar Farms and Battery Storage line in the approved capital programme as set out in section 5 of the report; and

3)    Delegated authority to the Assistant Director (Environment and Public Protection) to, at the conclusion of the procurement process, award the pre-construction contract, and design and build contract for the scheme provided that the scheme can be delivered within the budget as outlined in the Business Case.
