P649 MCDH Prefeasibility Report r2.doc 3

1 Introduction In November 2012 Hydroplan undertook a desktop assessment of hydro potential within the Forestry Commission land in Fiunary Forest, Morvern, and subsequently successfully tendered for conducting a prefeasibility study and risk evaluation for Phase 1, scope as identified in the tender invitation. A site survey was conducted over two days (15th & 16th January 2013). This report is a brief pre-feasibility report based on this preliminary site visit. The scope of the study includes the following: • Establish flow rates through hydrology based on industry based software • Undertake head measurement using handheld GPS and from maps • Provide an estimate of Power, the Average Annual Energy Production (AAEP)

for each scheme using an in-house computer programme, FDCENG. (The accuracy of these estimates is approximately +/- 20%, which will improve when more site data is collated and will be outlined any running constraints as well)

• Provide an estimate of CAPEX with accuracy of +-30% and OPEX • Consider and report on any readily identifiable environmental issues which

could alter the scheme economics • Provide a report (including schematic diagrams of the key elements)

summarising the schemes • Undertake an informal Grid Assessment (based on knowledge of the area)

A brief commentary on the various schemes and their main components is given in Sections 2.2 to 2.6. Section 3 provides an outline of the technical parameters and environmental considerations. Section 4 considers the scheme costs and economic viability and Section 5 provides a summary and proposed Next Steps. The scheme layout with the intake and powerhouse positions is presented in the Appendix A of this report.

2 Site Characteristics

2.1 Site Survey During the site survey, as many of the scheme components were visited as possible. Here follows a brief commentary on each scheme’s components.

2.2 Scheme 1 - Allt Achadh Forsa Intakes In addition to the intake position Int1-1 as marked in the desktop study, a new intake position Int1-0 was identified at the lower reach. Similarly, in addition to intake position Int1-1a, a new intake position Int1-1b was identified in the upper reach of this burn. All identified intake positions are good with bedrock available. Int1-0, which catches all tributaries, is located at approximately 102m AOD and Int1-1 at 223m AOD.

There were two existing intake structures identified on the Allt Achadh Forsa. The upper structure is the Scottish Water supply intake currently providing water supply to Lochaline. Therefore a higher than the normal compensation flow would be required from the Int1-1 to ensure normal operation of this intake at all times. The lower structure previously serviced the nearby mine with water, but is no longer in use. The other proposed minor intakes Int1-2, Int1-3 and Int1-4 were not visited specifically as the watercourses & catchments appeared too small. It is possible that they could accommodate a simple prefabricated intake structure if required, but for the purposes of this study these intakes have been discarded. Pipeline The pipeline route from each identified intake appears buildable. A more detailed assessment, with trial pits, could further refine the route.

Powerhouse Two possible powerhouse positions were identified: PH1 at the lower boundary of the forestry block, at approximately 69mAOD; and PH1a, on Ardtornish Estate land adjacent to the shore at approximately 30mAOD. PH1 is the simplest position and has been used in this study. PH1a would provide additional head, but is technically difficult due to the steep ravine nature of the topography.

2.3 Scheme 2 - Allt a Choirs Intake The proposed intake Int2 has been moved slightly upstream in comparison to the desktop study to approximately 110m AOD. The pipe exit is possible from both banks. Pipeline The pipeline could descend either on the left bank of the right bank. The left bank is through predominantly commercial forest; the RB is beside an existing forestry track before descending through lower grade commercial forest. The decision would probably be influenced by the felling plan, but for the sake of this study the left bank has been selected. Powerhouse The proposed powerhouse position PH2 is at approximately 23mAOD. Options exist on both the left bank and right bank.

2.4 Scheme 3 - Allt a Bhioda

Intake The proposed intake positions Int3-1 and Int3-2 have been moved slightly upstream to approximately 74m AOD by an existing forestry track. The pipe exit is possible from both LB and RB. In addition to those two upper intakes, another single intake position Int3-1a has been identified further downstream at approximately 60mAOD. Again the pipe exit is possible from both LB and RB.

P649 MCDH Hydro HD/TP/AJV March 2013

P649 MCDH Prefeasibility Report r2.doc 5

Pipeline The pipeline route is buildable but is rather long for such a small scheme, which may render it uneconomical. Powerhouse The proposed powerhouse position PH3 at approximately 33mAOD is reasonable position on the left bank.

2.5 Scheme 4 - Allt an Aoinidh Mhoir Intake The proposed intake Int-4 can be easily located beside an existing forestry track. The pipe exit is possible from either the left bank or the right bank. Pipeline The pipeline route is relatively easy but as on Scheme 3 may be rendered uneconomical because of its length. The pipeline on scheme 4 also runs in close proximity to an area of archaeological significance (the old township), which would have to be carefully considered. Powerhouse The proposed powerhouse position PH4 at approximately 21mAOD is reasonable on the left bank.

2.6 Scheme 5 - Barr River Intakes In addition to the proposed intakes (Int5-1 and 5-2) at the upper reach of each tributary of the Barr River (as identified in the desktop analysis) intake positions (Int5-1a and 5-2a) were identified slightly downstream on each burn. Intake 5-1 is located at approximately 187m AOD. There is good bedrock although the structure would entail long wing walls, and the pipe exit is reasonably constrained for about 40m immediately downstream. Intake 5-2 is located at approximately 182m AOD. Again there is good bedrock, although the structure would require large excavation for the pipe exit or a significant height structure. Intake 5-1a located at approximately 156m AOD, and is a good location with an easy pipe exit on the right bank. Intake 5-2a located at approximately 148m AOD, and is a good location with easy pipe exit on the right bank. Pipeline The pipelines have associated difficulties with the pipe exit on the upper intakes, but despite this, it is possible with benching and stabilisation. Beyond this, the pipeline routes appear to be not too difficult.

P649 MCDH Hydro HD/TP/AJV March 2013

P649 MCDH Prefeasibility Report r2.doc 6

Powerhouse There are three possible powerhouse positions: PH5 at approximately 53mAOD, PH5a beside the shore at approximately 8mAOD and PH5b at approximately 58mAOD. PH5 is located between the tributaries and has a few meters extra head than the PH5b position which is on the RB. An extra road and pipe bridges would be required for accessing PH5. PH5b is by far the easiest option and would result in the shortest pipe route. PH5a is located close to the sea and could be location on ether bank with several good positions with bedrock and pools for water return. However, being close to the shore at the bottom end of the river there is likely to be significant fisheries concerns. PH5a does though provide some extra head of ~50m, but with a significantly longer pipeline.

3 Technical and Environmental Considerations 3.1 Technical Parameters

A summary of the proposed layout of each individual scheme is shown in the revised Scheme Layout (Drawing No. P649 10001 r0) presented in Appendix A. An estimate of the Average Annual Energy Production (AAEP) has been made based on the Low Flows Enterprise (LFE) hydrology programme. Variable compensation flows have been considered in this analysis, which has a significant impact on the AAEP. The technical parameters of each scheme and their respective options are presented in Table 3.1, 3-2, 3-3 and 3-4 below and overleaf. Table 3.1 – Technical Parameters (Scheme 1)

3.2 Grid Assessment

Scheme 1 Scheme 1 capacity varies from 78kW - 174kW depending on option selected. The powerhouse is situated nearby the 33kV overhead line running beside the A884 to Lochaline. Schemes 2, 3, 4 & 5 Schemes 2, 3, 4 & 5 capacities vary from 15kW – 1220kW depending on number of schemes developed and option selected. Each scheme’s powerhouse nearest distribution point is the 11kV twin phase line running beside Loch Arienas to Loch Teacuis. This line could possible accommodate a small scheme (i.e. Scheme 3 or 4) but the larger schemes (i.e. Scheme 2 and 5) or the cumulative effect of all schemes, would necessitate a significant upgrade to the current overhead line that serves Loch Teacuis. There may also be further strengthening required on the 33kV line that serves Lochaline and Scheme 1. Considering this, there may be synergies applying individually or co-operatively with neighbours for these schemes.

3.3 Environmental Considerations From an initial search and general enquiry, the following environmental considerations are noted: -

• The proposed schemes are not within any designations but are close to Loch Sunart SSSI and SAC.

• Some of the rivers flow directly into the sea, hence there are likely to be migratory salmon and sea trout in the lower reaches of the some of the burns. However, this would need to be confirmed by a fisheries survey.

• Most of the schemes are within forestry hence the surrounding habitat is likely to be poor. Having said these habitats often contain pockets of rare species and can be support good habitat for protected mammals and birds.

• Most of the scheme elements are well hidden from view and the visual impact of the scheme would be small.

Although the above suggests that the schemes would have a minimal impact on the environment, it is expected that the usual environmental surveys will be required: -

• Archaeology • Habitat • Fisheries • Protected Mammals • Landscape and Visual Impact Assessment (LVIA) • Access & Traffic • FWPM • Bryophytes • Birds (possibly)

However, unless these produce an unexpected find, it is anticipated that planning permission should be relatively easy to achieve. Early negotiation with SEPA and SNH is recommended in order to identify any showstoppers early on the development of the project.

4 Economic Viability

4.1 Basis of Costing Project costing is largely dependant on the method of contracting the schemes. If a developer wants a “hands off” approach then he might opt for a “turnkey” contract and so would expect to pay more for this. Alternatively, a “DIY” approach would be somewhat less overall cost. The costing represented in the tables below are mid-range using relatively small but experienced contractors.

4.2 Option Costs The capital expenditures (CAPEX) of the selected options are presented in Tables 4.1, 4.2, 4.3 and 4.4 below. Table 4.1 – Option costs (Scheme 1)

5 Discussion

5.1 Conclusion

There is reasonable opportunity for hydro development on the Forestry Commission land in Fiunary Forest, Morvern for a community project, which the community development company may wish to consider further. The opportunities are summarised below. Scheme 1 appears a good opportunity to progress a small 100kW scheme and is advantageously near to the community and the distribution network in Lochaline, but the supply to the Scottish water intake would have to be carefully defended.

Scheme 2 is the simplest 100kW scheme available for development by the community company, but would rely heavily on a grid upgrade. Scheme 3 is a relatively poor scheme with a long pipeline, but might not require a grid upgrade, which could make it attractive. Scheme 4 is a relatively poor scheme with a long pipeline and due to the archaeological significance in the area may be best discarded. Scheme 5 is the largest opportunity to progress a 500 or 1000kW scheme, but does come with the challenges and costs of a larger scheme, and relies heavily on a grid upgrade in the area.

5.2 Next Steps

• Consider applying for grid capacity for Scheme 1 • Consider applying individually or co-operatively with neighbours for a grid

connection with SSE for some or all of Schemes 2, 3, 4 & 5 Pending the outcome of these applications,

• Establish a gauging station on each burn and commence flow monitoring as

soon as possible • Undertake topographic survey of the intake and powerhouse to confirm head

and layout • Refine the Average Annual Energy Production (AAEP) and budget costing

once some gauged flow data is available.
