# The Springwell Solar Farm Order 2026, Paragraph 20: Electrical noise

Extent: E+W

(1) Unless otherwise agreed in writing by the relevant planning authority in consultation with the Ministry of Defence, no individual part(s) of the authorised development featuring Work Nos. 1 – 6 may commence unless or until an electrical noise interference management plan which accounts for the electrical noise emissions of that part(s) has been submitted to and approved by the relevant planning authority, such approval to be in consultation with the Ministry of Defence.
(2) The electrical noise interference management plan (unless otherwise agreed in writing between the relevant planning authority and the Ministry of Defence) must include but is not limited to—
(a) manufacturer’s specifications for all electrical equipment including but not limited to solar PV modules, balance of solar system plant, substation, transformers, battery energy storage systems, inverters, switch gear, electrical cables included within Work Nos. 1 to 6;
(b) details of measures designed to prevent electrical noise interference being caused to technical installations at RAF Digby or forming part of the East 1 Wide Area Multilateration Network;
(c) report(s) and supporting evidence, using methodologies and standards accredited by the Ministry of Defence, to demonstrate how Work Nos. 1 to 6 (featured in the part(s) of the authorised development being submitted for approval under sub-paragraph (1), together with any part(s) of the authorised development featuring Work Nos. 1 to 6 that have already been approved under sub-paragraph (1) will be constructed, tested, operated, and maintained throughout the life of the development to ensure that individually or cumulatively any electrical noise emissions from each part(s) of the authorised development that will be built and in operation at the same time will be prevented or otherwise constrained to a level agreed by the Ministry of Defence to safeguard the effective operation of the technical site installations at RAF Digby or forming part of the East 1 Wide Area Multilateration Network;
(d) a protocol through which the undertaker can be notified by the Ministry of Defence of electrical noise interference issues or observations, the measures that would be taken by the undertaker to investigate, and a description of the approach to resolving, rectifying or mitigating those impacts and timescales for the undertaker to implement any such address; and
(e) parameters or requirements that would need to be met by any replacement or modification of the electrical equipment that is the subject of the management plan being submitted for approval under sub-paragraph (1), together with protocols through which the undertaker must—
(i) notify the Ministry of Defence of any replacement or modification of electrical equipment (such notification to provide confirmation that the electrical equipment complies with the approved management plan) using the evidence, methodologies or accredited standards referred to under paragraph (c); and
(ii) seek the Ministry of Defence’s prior approval if the undertaker intends to replace electrical equipment that is the subject of the approved management plan and such equipment would not be in accordance with the approved management plan. All submissions for prior approval are to be supported with a relevant assessment(s) using evidence, methodologies or accredited standards referred to under paragraph (c).
(3) Unless otherwise agreed in writing by the relevant planning authority in consultation with the Ministry of Defence, the electrical noise interference management plan must be implemented as approved and maintained throughout the operation of the part(s) of the authorised development to which the plan relates, to ensure that no single part(s) of the authorised development for the duration that they may be built and operated individually or thereafter when connected together will produce any electrical noise emissions in excess of a level agreed by the Ministry of Defence to safeguard the effective operation of the technical site installations at RAF Digby or forming part of the East 1 Wide Area Multilateration Network.
(4) For the purposes of sub-paragraph (1), “part of Work Nos. 1 – 6” means all of the works comprised in Work Nos. 1 – 6 for a specified spatial part(s) of the Order limits, and would include installation and commissioning of all electrical systems required to enable such a part(s) to function as intended in its operational state.
