Bunavoneader Hydro Scheme update

Posted on:

It’s nearly five months since the last update on our hydro scheme. Since then we have been beavering away, trying to get the finance in place to build the scheme. We have a loan offer from the Co-op Bank, but it’s only for 67% of the project cost. This is a lot less than we had anticipated. This leaves us to source a further £200,000.

The rules for the government’s Feed-in-Tariff scheme have changed over the last year -this is the scheme that will pay us for creating green energy. It no longer allows the use of public funding for such community schemes. This is now regarded as a State Aid, which would give us unfair advantage over more commercial organisations. So, we are left to source the additional funding from private trust funds or commercial lenders.

Our first port of call was to the Bank of Scotland. Since it was established in 2003, the North Harris Trust has banked with BoS. We asked them for a secured loan for the hydro-scheme – and they refused us! Despite eight years of “in-credit” banking and huge assets to borrow against, despite the government putting pressure on banks to lend to small businesses – they said no. So we are now exploring every other avenue open to us, to source private funding to make the scheme happen.

The good news though is that we now have a Licence from SEPA to extract our water from our river.

Micro-hydro – what does it look like?

Posted on:

the intake weir

In late January, I was lucky enough to attend a hydro briefing session at the Abernethy Trust’s centre at Ardgour, near Fort William. The Aberbethy Trust is a charitable organisation that runs a number of Outdoor Activity Centres. Last year they commissioned a 90kW hydro-electric scheme at their Ardgour site, so a number of community groups descended on the site to find out how they did it. Community Energy Scotland rounded up groups from Calendar, Applecross, Sleat-Skye, Mull, Creetown-Dumfries and Harris all of whom are in the process of developing schemes.

The Bunavoneader hydro-electric scheme will be of a similar size, so we were very interested in their designs and their choice of equipment.

a 90kW turbine and generator

The Ardgour scheme is on a very small river that drops 120m to the shore of Loch Linnie – Unlike the Bunavoneader scheme which has lots of water but only a 30m drop to the turbine house. The turbine is much the same size though, so it gives a good idea of what we will be siting below the bridge at Bunavoneader. The big advantage that the Ardgour site has is in the ground conditions.  They were able to build a track up to the intake with an excavator –no need to blast rock or ship in tons of infill. This goes some way to explain why the North Harris scheme will cost three times the Ardgour final bill.

Grid Connection

 

The scheme started generating in June. The ultimate aim is to build a private electricity grid around the site. This will feed their own electricity into the centre and all the surrounding staff houses. For now though, electricity is fed into the national grid and sold. Abernethy is one of the first schemes to find its way through the new  Feed-in-Tariff process. Six months on and they are hoping to get their first cheque .

The story to take away from the visit is that it is possible. Barry, like many of the community representatives is not an engineer or a hydro-developer, but by sheer persistence over a three year timeframe, has delivered a scheme that is now earning money for his charity. So successful has it been, he is now planning a second scheme in the next valley along.

Thanks to Community Energy Scotland for facilitating, Development Trust Association of Scotland for funding the trip, and Barry Edmundson from Abernethy, the brains behind the scheme.

Historic Scotland's latest publication

Earlier in the year, a team from Historic Scotland came to Harris to talk to various people who are or have been involved in Hydro-power.  After extensive research, visiting sites throughout Scotland, a book was launched. This is now available to the public.

“The significant and early development of hydroelectric power in Scotland results not least from its combination of topography and weather. But this potential would not have been realised without the pioneering vision of a handful of architects, engineers and politicians whose personal energy and skills meant that Scotland has led the world in the development of this green energy source at various times in its history. The legacy of this pioneering development is a vibrant hydro sector which contributes to Scotland’s status as a net exporter of power to the rest of the UK. Scottish  Hydroelectric schemes are of national significance to the UK energy sector, generating around 12% of the gross power consumed in the UK in 2008. This is a spectacular Scottish success story. The hydroelectric power movement has led to the creation of many internationally important buildings and structures, demonstrating architectural as well as engineering achievement. This book traces the development of the industry through some of these key figures, from its roots in the aluminium industry through to hollow mountains with the capability to provide emergency power for whole of the UK. “ Malcolm Cooper Historic Scotland
