Ref­er­ence: PRE/2026/0025

Applic­ant: Scot­tish Hydro Elec­tric Trans­mis­sion plc

Date called-in: N/A

Recom­mend­a­tion: For information

Pur­pose

  1. The pur­pose of this report is to: a) inform the Plan­ning Com­mit­tee of a Pro­pos­al of Applic­a­tion Notice (PoAN); and b) allow mem­bers to raise any views on the issues to be addressed in any sub­sequent plan­ning application.

Back­ground

  1. The Plan­ning etc. (Scot­land) Act 2006 requires that any developer pro­pos­ing to sub­mit a major plan­ning applic­a­tion must under­take stat­utory pre-applic­a­tion con­sulta­tion with the com­munity. Before com­men­cing this con­sulta­tion, the developer is required to serve a ​‘Pro­pos­al of Applic­a­tion Notice’ (PoAN) on the Plan­ning Authority.

  2. This report relates to a PoAN for a new 400kV sub­sta­tion and under­ground cable con­nec­tion on land to the south of the A86, Strath­mash­ie. The PoAN was sub­mit­ted to the High­land Coun­cil on 26 August 2026, who sub­sequently noti­fied the Park Author­ity on 11 Septem­ber 2026. Mem­bers are asked to note that this PoAN is inten­ded to form the basis of a sub­sequent plan­ning applic­a­tion. The sub­mit­ted inform­a­tion com­prises the Loc­a­tion Plan (Appendix 1a) and the PoAN form (Appendix 1b).

  3. In Decem­ber 2015, Plan­ning Com­mit­tee agreed a pro­ced­ure to allow Mem­ber involve­ment in pre-applic­a­tion advice for major plan­ning applic­a­tions, since these applic­a­tions are nor­mally called in for determ­in­a­tion by the Park Author­ity. The pro­ced­ure involves officers present­ing the inform­a­tion provided by the applic­ant as part of any PoAN sub­mis­sion, along with a short cov­er­ing report to high­light the rel­ev­ant policy frame­work, likely mater­i­al con­sid­er­a­tions and key issues asso­ci­ated with the pro­posed development.

  4. In line with the agreed pro­ced­ure, it is import­ant to note that Com­mit­tee Mem­bers are not being asked to dis­cuss the mer­its of the pro­pos­al. Rather, they are asked to note the rel­ev­ant issues that a future applic­a­tion would be expec­ted to address and advise of any addi­tion­al mater­i­al issues they wish to be drawn to the applicant’s attention.

The pro­pos­al

  1. The pro­pos­al is for the con­struc­tion of a new 400kV sub­sta­tion and under­ground cable con­nec­tion com­pris­ing new build­ings, plat­form, plant and machinery, access, laydown/​work com­pound area(s), drain­age, land­scap­ing, track upgrades and install­a­tions, under­ground cabling and oth­er ancil­lary works on land south of the A86, Strath­mash­ie. The pro­pos­al is neces­sary to con­nect the con­sen­ted Ear­ba pumped stor­age hydro scheme into the grid. A sep­ar­ate Sec­tion 37 applic­a­tion will be sub­mit­ted to the Scot­tish Government’s Energy Con­sents Unit in sum­mer 2027 for the asso­ci­ated over­head line and tower works required to upgrade the Beauly to Denny trans­mis­sion line and bring the devel­op­ment online.

  2. The pro­pos­al com­prises land with­in the High­land Coun­cil loc­al author­ity area, with a large pro­por­tion of the red line bound­ary fall­ing with­in the Cairngorms Nation­al Park Author­ity bound­ary. The sub­sta­tion is pro­posed in prox­im­ity to the exist­ing Beauly to Denny over­head line, approx­im­ately 2km south-east of Feargour cot­tage, Kin­loch­lag­gan. The under­ground cable cor­ridor would extend south-west from this loc­a­tion towards the con­sen­ted Ear­ba pumped stor­age hydro scheme site at Lochan na h‑Earba.

  3. The PoAN sub­mis­sion explains that the applic­ants pro­pose to carry out two pre-applic­a­tion pub­lic con­sulta­tion events as required by legis­la­tion. The events will be held at Lag­gan Com­munity Hall between 3pm and 7pm on 7 Octo­ber 2026 and 24 March 2027. Both events will be advert­ised in the loc­al press.

Site descrip­tion

  1. The site falls with­in the Ard­verikie Estate and com­prises areas of wood­land and open moor­land. The River Mash­ie, River Pat­tack and its trib­u­tar­ies flow through the site. Vari­ous tracks are present across the site and access­ible to act­ive travel users and estate vehicles. The Beauly to Denny over­head line tran­sects the north­ern por­tion of the site. Across the site small areas of loc­al­ised sur­face water and river flood­ing are iden­ti­fied on SEPA’s flood maps. Giv­en the extent of land with­in the site bound­ary which is not at risk of flood­ing, it would be reas­on­able to assume that the devel­op­ment will be sited to avoid flood risk areas.

  2. A small num­ber of scattered prop­er­ties are loc­ated across the Ard­verikie Estate used as both per­man­ent res­id­ences and short-term lets.

Devel­op­ment plan context

  1. Any pro­posed devel­op­ment will be con­sidered against the rel­ev­ant policies and guid­ance as con­tained with­in the Devel­op­ment Plan. For the parts of the devel­op­ment with­in the Nation­al Park bound­ary, this com­prises the Cairngorms Nation­al Park Loc­al Devel­op­ment Plan 2021 (LDP) and the Nation­al Plan­ning Frame­work 4 (NPF4). Where there is con­flict between policies, NPF4 policies will be used.

Poten­tial mater­i­al plan­ning con­sid­er­a­tions and issues to address

  1. Key mater­i­al plan­ning con­sid­er­a­tions for any sub­sequent applic­a­tion are as fol­lows: a) The prin­ciple of devel­op­ment b) Land­scape and visu­al impacts c) Design and lay­out d) Flood­ing and sur­face water man­age­ment e) Envir­on­ment­al impacts (includ­ing impacts on any des­ig­nated sites) f) Eco­logy g) Forestry and wood­land h) Archae­ology and cul­tur­al her­it­age i) Amen­ity (includ­ing noise, vibra­tion and air qual­ity) j) Access (includ­ing traffic, trans­port, and pub­lic access impacts)

Con­clu­sion and next steps

  1. The report presents the inform­a­tion sub­mit­ted to date as part of the PoAN. Officers have sum­mar­ised the policy con­sid­er­a­tions against which any future plan­ning applic­a­tion will be con­sidered as well as poten­tial mater­i­al plan­ning con­sid­er­a­tions and key issues. The sum­mary is not exhaust­ive, and fur­ther mat­ters may arise as and when a plan­ning applic­a­tion is received, and in the light of pub­lic rep­res­ent­a­tions and con­sulta­tion responses on any form­al plan­ning application.

  2. It is recom­men­ded that the Com­mit­tee notes the sub­mis­sion of the PoAN and advises of any addi­tion­al mater­i­al issues it wishes be brought to the applicant’s attention.

Recom­mend­a­tion

That mem­bers of the com­mit­tee: a) note the Pro­pos­al of Applic­a­tion Noti­fic­a­tion; b) note the Officer’s advice to the pro­spect­ive applic­ant as to issues to address; and c) advise of any addi­tion­al rel­ev­ant issues to be addressed in any future plan­ning application.
