The World’s First Ever Archimedes Screw Fest

On Saturday, October 15th 2016 the first ever Archimedes Screw Fest took place at the Hydro Power Station on Totnes Weir.

The event marked the Hydro Station’s first birthday and a year of green electricity generation.

There were several family activities running throughout the day providing an opportunity to learn first-hand about the local ecosystem and the amazing renewable energy source right on our doorstep. Tresoc’s Director of Engineering, Alastair Gets, led tours/talks around the site throughout the day, which included a close up inspection inside the plant and of the fish pass.

Jane Brady, as Director of Communications, has been working to deliver an information signage board for the site. Part of the day’s event invited visitors to add their comments and preferences to how that sign could take form. Stories and knowledge of the River Dart were shared, whilst children crafted salmon shapes that then were woven into a hand-made fish net. The inspiration continued, as the net went on to take residence at St John’s primary school for future class lessons of a river focus. Citizen scientists could also sign up to become active members of the community taking care of the health and future of the river ecosystem; with the WestCountry Rivers Trust on hand to respond to queries about the River Dart. The Totnes Rubbish group led a volunteer litter pick along the river walk to the Weir.

Sadly, Archimedes, the man who pioneered the screw technology, was not able to join us on the day; [reported to have had a cold from staying in the bath far too long]. Instead, we sampled his favourite dish, arancini (provided by the Kitchen Table), in his honor.

Tresoc worked in collaboration with Dart Renewables, the Hydrosense consortium and Triodos bank during the development of the weir and launched an exclusive share offer to its members earlier this year, helping to secure local community investment in its local renewable resource.

Tresoc is now developing Staverton Leat Hydro in partnership with Hydrosense, The Dartington Hall Trust and Triodos Bank. There will be more on this at the upcoming AGM on November 30th, when guest speaker, Karen Williams, the Chief Operating Officer of the Trust, joins the evening to talk about working in partnership with Tresoc.

Thanks to Landustrie and Dart Renewables Ltd, who sponsored the Archimedes Screw Fest, and to all those who joined us at the weir and made the day so special. Archimedes Screw Fest was part was part of TTT Open Eco Homes weekend.

Dispatches from the front line of community renewable energy development

Dear all,

Its been over 6 months since the Tresoc Team reported on the state of affairs of the Society to our loyal and patient members at the AGM.  Our press releases and members emails tend to focus on newsworthy events but its been quite busy at Tresoc control since December and now seems to be a good time for an update on progress in achieving what we set out to do at the AGM; to bring Tresoc into profit in the current financial year.

Following the AGM, we’ve completed the award winning SHINE Project with South Devon Rural Housing Association with the proceeds of our 2014 share offer and drawn down a loan of £168,000 from the Charity Bank to purchase the solar roof at Hatchlands Farm.

Some of you have taken up the exclusive offer to Tresoc members to buy shares in Dart Renewables Ltd, the developers and owners of the hydro power station at Totnes Weir, now supplying KEVICCs and the Foundry on Babbage Road Industrial Estate with cheap, carbon neutral electricity.  This has had the additional happy effect of giving the Tresoc coffers a bit of a boost for the benefit of all our members.  In return for promoting the share offer, Tresoc has received £9,120 in cash, 3% of the total £304,000 raised, plus 1% of the shares in DRL, a company with a current market value i.r.o. £3,000,000.

It’s highly encouraging to be working with the Charity Bank and Triodos bank, both supporting development of the community energy sector, with a positive view of the prospects for sustainable growth.

Two weeks ago, in association with the Hydrosense Consortium and Triodos Bank, Tresoc established the Staverton Hydro Community Benefit Society Ltd to develop, own and operate a new 100 kW hydro power station at Staverton Leat.   Fishtek, members of the Hydrosense Consortium, have been engaged over the past year with local anglers and the Environment Agency to obtain an abstraction licence to draw water through the leat.  Tresoc has started work with Staverton residents to explore how best to ensure that the power plant will be of real benefit to the local community. We’re aiming to be ready to raise capital through a share offer organised by Triodos Bank at the end of 2016, to build and commission in the Spring of 2017.

Right now, we’re consolidating all the legal and administrative work involved in the ownership and operation of these assets into Tresoc’s business management systems.  We’re also upgrading our financial capabilities with staff training in Sage business software, from our accountants, Darnells, in preparation for the next phase of the Society’s growth.  Amongst many other functions, Sage will enable us to improve the speed and accuracy of our financial forecasting and calculate how much interest we expect to pay to members from projected profit in the current year.  With that piece of information, and depending on the rate of interest we can afford to pay, we are considering another small Tresoc share offer to finance new community owned solar roof installations at Lescaze House and Bidwell Brook School in Dartington.

Also back on the drawing board is on-farm anaerobic digestion at Old Parsonage Farm, Dartington with new tenant farmer, Jon Perkin, the Dartington Hall Trust and Totnes company, New Generation Biogas. We have a new Tresoc intern about to contact local catering establishments to see if we can find a way to make it easier and more profitable for them to put their food waste into a bin to supplement farmyard manure feedstock for the digester.  Food “waste” not only makes the operation more productive but also adds valuable nutrients to the digestate for use as a high quality, balanced fertiliser on the farm.

I’m pleased to say that there are other projects in the pipeline at this very exciting period in the growth of community owned renewable energy in Totnes, and beyond.  It’s hard to judge how much information to make public about projects in the early stages of development in a commercially competitive environment.  One thing that is certain about a business plan is that it never turns out exactly as expected but we are acutely aware of the value of keeping our members informed about what we’re doing and where we’re heading.

Do please feel free to ask me about Tresoc if you see me in Totnes. And here’s to more sunshine and rain, plenty of both at the moment, fuelling the growth of your local community owned renewable energy Society!

Totnes Weir hydro Share Offer reaches target

Tresoc Members invested just over £300,000 in the iconic 300 kW Totnes Weir hydro power plant. Because the target was reached through local investment, there was no need to open up the share offer to a wider audience—local investment works! Triodos have sent out share certificates. If you missed out on this opportunity, don’t fret, more good things are on the way. We have a working partnership with the Hydrosense consortium, developers of the Totnes weir site, and we are moving forward with a new, local hydro project and more on-roof solar. Get in touch if you’d be interested in investing.
