Reference:  23/01276/PAN 
Applicant: Ylem Energy Ltd 
Proposal: Proposal of Application Notice for: Installation of 50Mw battery energy storage
system to balance the electricity network and facilitate renewable energy
deployment  
Site Address: Ardencaple Farm, Rhu, Helensburgh, Argyll and Bute
____________________________________________________________________________ 
1.0 INTRODUCTION 
This report informs the Planning Committee of the submission of a Proposal of Application
Notice (PAN). The submission of the PAN accords with the provisions of the Planning etc.
(Scotland) Act 2006 and was made valid on 14.08.23. The development which is subject
to the PAN is of a scale which will be an application to The Planning Authority as the
capacity of the storage facility will not exceed 50Mw in total capacity. (Above 50Mw would
require a Section 36 Application under the Electricity Act) 
The submitted information includes: 
 Proposal of Application Notice
 Location Plan
 Copy of newspaper adverts
 Community Consultation Presentation Dated 10.8.23 
The applicant has set out in detail their proposals to ensure sufficient opportunity is
provided for the community to view and comment on the proposals in advance of the
submission of a formal application. The applicants have confirmed in the PAN form that
the following consultation steps will be undertaken: 
 Consultation with Helensburgh Community Council
 Notification of the following Parties, 
Cllr Mark Irvine
Cllr Maurice Corry
Cllr S I Paterson
Jackie Baillie MSP
 Undertaking three community  consultation events 
 Advertising events within the Helensburgh Advertiser 
In addition to the above, the applicants have stated that they will write to all residents
within a 750m radius of the proposed site and put up posters in local shops and
community facilities.

Officers consider that the steps set out in the PAN are acceptable and in accordance with
the requirements of the Regulations to ensure appropriate community consultation is
undertaken. 
2.0  DESCRIPTION OF PROPOSED DEVELOPMENT 
The PAN provides notice of the developer’s intention to submit a planning application for
the erection and operation of a 50Mw battery storage facility.   The proposed compound
boundary comprises some 1.2 acres (120m x 40m). By means of general background the
applicants submit that: 
Battery Energy Storage Systems (“BESS”) are rechargeable batteries which are used to
store electricity imported from the grid at times of surplus. This power can come from
different sources, such as solar PV, during periods of excess supply or wind generation at
night when demand is low. This electricity is then discharged at times when there is
demand which exceeds supply....BESS sites are similar conceptually to reservoirs which
hold drinking water, or gas holders which store natural gas for heating. 
The applicants have submitted a copy of their community presentation of 10.8.23 which  
contains additional information on the proposals, and also an illustrative layout of a similar
facility to provide a general indication of the likely scale and appearance of the
development. This is available to view on the public access system.(Document 22986637) 
3 SITE DESCRIPTION 
The proposals will be located in a field north of the West Highland Railway Line and south
of existing high voltage overhead lines operated by Scottish Power. It is within the general
field patters of Ardencaple Farm located some 350m to the south east of the main
farmhouse buildings. 
The application site currently comprises part of a large field which appears to be used as
pasture land. A band of trees is located along the Western Boundary of the site and also
in the south eastern corner of the field. The applicants submit that the development is
approximately 300m from the nearest residential property. 
The site slopes from north to south from a high point of 100m AOD down to 75m AOD with
the application site being on the lower lying part of the site adjacent to the railway line
which forms the southern boundary of the site. 
For Members general information, the application site is located within the Green Belt. It
is not located within either the Duchess Woods or Highlandman’s Wood Local Nature
Conservation sites, which are located to the south, east and north of the proposed site. 
4 DEVELOPMENT PLAN POLICY

These appear to be the most relevant policies. However this cannot be finalised until such
time as a formal application has been submitted and the details of the proposals finalised. 
Other Relevant Policy Considerations: 
Emerging Local Development Plan (LDP2) 
The emerging Local Development Plan (LDP2) will replace the current Local Development
Plan 2015, once adopted. On 13th June 2023, the Scottish Government’s Planning and
Environmental Appeals Divisions issued their Report of Examination on the Council’s
LDP2. At the time of writing this Pre-application report, the LDP 2015 remains the adopted
Local Development Plan, however, the Examination Report of the Draft LDP2 is a material
consideration of significant weight and may be used as such until the conclusion of the
LDP2 adoption process. (It is likely that this will form the statutory plan before the end of
2023 although this is subject to ongoing reporting to Members and adoption procedures). 
Policy 02 – Outwith Settlement Areas
Policy 04 – Sustainable Development
Policy 05 – Design and Placemaking
Policy 06 – Green Infrastructure

5.0 POTENTIAL MATERIAL CONSIDERATIONS 
In respect of this proposal, it is considered that the following matters will be material
considerations in the determination of any future planning application: 
a)  LDP 2
b) National Energy Policy Objectives;
c) Economic Benefits;
d) Roads, Transport and Access;
e) Flood Risk, Water Quality and Drainage;
f) Peat and Soils;
g) Access and Recreation;
h) Natural Heritage and Biodiversity (including impact on designated sites);
i) Impact on Woodland;
j) Built and Cultural Heritage;
k) Design and Layout;
l) Landscape and Visual Impact (including cumulative impacts);
m) Noise and Vibration;
n) Telecommunications;
o) Construction Impacts;
p) Any other material considerations raised within representations. 
Members will note from the file that third party concerns/objections relating to the
proposals have been sent to the Planning Authority as part of the PAN Consultation
Process. For clarity, it is for the applicant to consider any concerns/objections at this stage
and demonstrate by means of a PAC report to accompany any future major planning
application how these matters have been considered. 
It is not for the Planning Authority to have regard to these matters at the current time as
no determination is sought on the merits of the proposal through the PAN process. Should
concerns or objections remain in relation to any future planning application they can be
submitted to the Planning Authority and considered at the appropriate time. 
6.0 CONCLUSION 
The report sets out the information submitted to date as part of the PAN. Summarised are
the policy considerations, against which any future planning application will most likely be
considered as well as potential material considerations and key issues based upon the
information received to date. The list 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. 
7.0  RECOMMENDATION 
That Members note the content of the report and submissions and provide such feedback
as they consider appropriate in respect of this PAN to allow these matters to be considered
by the applicants in finalising any future application submission.
