The firm said the proposed substations are critical elements of plans to strengthen the electricity transmission network across the north of Scotland and Great Britain, enabling the connection and transportation of clean, homegrown power. The projects would support local jobs and businesses during construction and deliver significant long‑term economic benefits for their respective regions and the north of Scotland as a whole.

In both cases, the decisions to refuse consent went against the recommendations of the councils’ own planning officers, the positions taken by internal consultees and all key statutory agencies, none of whom raised objections to the proposals.

SSEN Transmission also expects to submit appeals shortly in relation to the proposed Hurlie and Fanellan substations, following decisions by Aberdeenshire Council and the Highland Council, respectively, to refuse consent for those developments, similarly against the recommendations of planning officers.

Alison Hall, director of development, said: “Upgrading the electricity transmission network in the north of Scotland is essential if Scotland and the UK are to deliver on our energy security and clean power ambitions. The proposed Emmock and Carnaig substations have been carefully designed to help meet that need. Our planning applications are informed by extensive development work, detailed technical assessment and thorough engagement with key stakeholders, including local communities.

“In addition to supporting clean, affordable power, these projects would deliver wider economic benefits, supporting jobs and local businesses during construction and helping to underpin longer‑term investment and economic growth.

“We strongly believe that we have developed robust and policy‑compliant proposals. Submitting these appeals will allow the merits of the projects to be fully and fairly considered, and we remain committed to engaging constructively with local communities and stakeholders throughout the planning process.”

While the appeals process is ongoing, SSEN Transmission will continue to carry out pre‑construction ground investigation works and surveys at proposed substation sites. These activities are permitted under existing development rights and are necessary to further understand ground conditions and identify site features, helping to inform detailed design and construction planning should consent ultimately be granted. Undertaking this work at this stage allows the project to progress responsibly and efficiently should consent be granted, without prejudicing the outcome of the appeals.
