In an earlier post it was reported that Ribble Valley members of Transition Town Clitheroe aimed to develop greater community resilience to cope with reduced future availability of fossil fuels and to adapt to climate change. They floated a community share offer in 2013 to raise money to generate community-owned clean energy on the River Calder.
The Scottish Farmer has now added news of another hydro project based at the Harlaw reservoir (above), outside Balerno, near Edinburgh, first mentioned on this site in 2013. The organisers found an upgrade of the existing micro-hydro scheme at Harlaw Reservoir a positive experience and are keen to share the benefits of such an investment, particularly as part of a community project.
The project aimed to provide an independent green energy source and income for the local community. Chairman and director of the community group, Martin Petty recalls that a village trust had been established to help the community and the hydro project was proposed. After a consultation, a co-op which offered shares in the project was set up. A feasibility study in 2010 confirmed that it was a practical and profitable proposition and after four years of planning, meetings and obtaining approvals, the group were in a position to build the project in July, 2014. Work started in September, 2014, and was completed in August, 2015, with the formal opening by the Minister for Business, Energy and Tourism, Fergus Ewing, taking place on September 1, 2015.
Harlaw Hydro Ltd is now known as a bona fide co-operative society (BENCOM) and it is registered under the Industrial and Provident Societies Act 1965, rather than as a company under the Companies Act. The society has seven directors and 250 shareholders, who together raised nearly £400,000.The profits generated by selling power to the grid will be used to sustain the scheme in the first place, pay the shareholders a dividend, and then benefit the local community.
The 95kW system will take water from the dam’s penstocks (reservoir dam outflows), returning flow to the dam discharge channel prior to it, forming Bavelaw Burn. A new turbine house (above) is located to the north east of the discharge channel, at the foot of the reservoir dam, immediately south of the disused building.The scheme will generate approximately 260,000kWh of green electricity per year – enough for approximately 100 average houses – saving 129 tonnes of carbon dioxide per year.
The project was the first in Scotland of its type and Mr Petty feels it has set an example to other communities: “Communities across Scotland have been energised by this project, and they’ve come to us as a point of advice, and now a number of others are doing the same as us. It’s great to see, and it’s great to be that point of contact.”
Commenting on the project, Mr Petty added: “We were lucky to have a great group of people on the engineer team, which was luckily made up of men who are all, or have been, engineers. The team included a mechanical, charted civil and electrical engineers, as well as a geologist and an architect, all of whom worked on a voluntary basis, so we were really lucky with that.”
