Dear Member,

As you well know, the hydropower sector has been hit hard by the recent maelstrom of Government policy changes and we now face a very challenging future. Intentional or non, the effects are real and we whilst we have been lobbying both DECC and the Treasury very hard and continue to do so, we have also been working with many MP’s and Peers in England and Scotland over the past 6 months. Amongst others, we have requested meetings with the Secretary of State, Amber Rudd and with the leader of the Conservatives in Scotland, Ruth Davidson.

In particular we have been supporting Baroness Featherstone in her work in the Lords to get the Government to rescind the tariff cuts through her ‘Regret motion’ which she has tabled. Her address to the Lords is Tuesday 2nd February and by bringing our numbers we can add weight to her plea – ‘Feed-in Tariffs (Amendment) (No. 3) Order 2015 Baroness Featherstone to move that a Humble Address be presented to Her Majesty praying that the Order, laid before the House on 18 December 2015, be annulled (SI 2015/2045). 20th Report from the Secondary Legislation Scrutiny Committee’

The BHA has also teamed up with one of our members, the Micro hydropower Association and their CEO Kate Gilmartin, so please add your name to the attached letter by signing our petition at the link http://www.publications.parliament.uk/pa/ld/ldordpap.htm

Please pass on to all those within your network and get them to sign as soon as possible.

Let me know if you have any questions

I attended the Regen South West Conference this week and the most rewarding and interesting talk was Graham Hillier on Tidal Lagoon Power. If you have the time take a look this weekend at this amazing technology and plan that can light up the UK, reduce the use of fossil fuels and clean up Britain.

Community Hydro Energy Proposal – Pymore, Bridport

Energize Stur Valley (a group comprising several people from Dorset Energized) – were asked by members of the local community to investigate the viability of installing a small hydropower electricity generation set-up on the river Brit, which runs through the village of Pymore near Bridport.

We at Dorset Energized are enthusiastic supporters of community led renewable energy schemes – and a great way to provide support is by giving practical assistance:

A site survey was carried out and a proposal has been created – you can see it below.

Would you like your community to generate its own electricity from the river

Peggs Farm Crossflow Turbine Installation near Child Okeford


Category: Community Energy, Water Power
Tags:


A 3.7 kW crossflow turbine has been installed at the end of the leat at Peggs Farm. There is a working 3.8 m diameter wheel also fed from the leat, which is still used to produce animal feed for the farm.

The site is on the Fontmell Brook – a tributary of the River Stour – between Fontmell Magna and Child Okeford. The installation of this renewable electricity generation is estimated to generate 14,000 kWh/yr saving 6 tonnes of carbon dioxide a year and provides for some of the high electrical demand at this diary farm. This farm diversification provides income to the farm from the Feed in tariff and sales of electricity. A crossflow turbine was chosen to match the head and flows and at this site. The rated flow of the turbine is determined by the 3.9 m head and flows available. To comply with the Environment Agency Good Practise Guidelines, a 300 mm diameter turbine, taking a maximum flow of 0.120 m3s was chosen. The project included repair of leaks in the leat wall and construction of a new brick turbine house for the turbine, generator, grid connect and control unit.

Extensive negotiation with the Environment Agency was required to ensure that the scheme design and methods of construction complied with the environmental standards expected to achieve the necessary Abstraction License and Flood Defence Consent. It was decided to install the turbine in a new lean-to building next to the existing mill where the wheel is located. The grid connection is arranged so that electricity generated supplies the needs of the site, only exporting to the grid when there is a surplus.

The total project budget was £60,000. Sowing Seeds provided £21,807 but the process from initial agreement to receipt of the grant took 3 years. This is one of three hydropower projects in the area in receipt of the grant, all using different hydro turbine technologies.

There are numerous old mill sites and other potential hydropower sites in Dorset. The Feed in Tariffs, sales of electricity and avoided import of electricity make development of these sites financially attractive. Project management is not beyond the scope of a talented amateur but the complexity of the design and license application process means that expert advice is usually required. It is intended (and required under the conditions of the grant received) that the project will be well monitored, documented and publicised to enable other Dorset hydro projects to learn from the experience gained in developing and maintaining hydropower at Peggs Farm.

The project was developed with Potent Energy – find out more at: www.potenergy.co.uk.

Benjafield Screw Turbine Installation near Gillingham


Category: Community Energy, Water Power
Tags:


A 5.5 kW screw turbine has been installed next to the weir at Benjafield Farm. The site is on Shreen Water – a tributary of the River Stour – between Mere and Gillingham in Dorset.

The installation of this renewable electricity generation is estimated to generate 28,000 kWh/yr saving 13 tonnes of carbon dioxide a year and provides for some of the high electrical demand at this cattle farm. This farm diversification provides income to the farm from the Feed in tariff and sales of electricity. A screw turbine was chosen to match the low head, high flows and requirement for fish protection at this site. The rated flow of the turbine is determined by the 1.8 m head and flows available. To comply with the Environment Agency Good Practise Guidelines, a 1.0m diameter turbine, taking a maximum flow of 0.320m3s was chosen. The project included stabilisation of the west bank and construction of a timber housing for the gearbox, generator, grid connect and control unit.

Extensive negotiation with the Environment Agency was required to ensure that the scheme design and methods of construction complied with the environmental standards expected to achieve the necessary Abstraction License and Flood Defence Consent. It was decided to install the turbine in a new excavation next to the existing weir. A V shaped notch in the weir has been provided to enable down river fish passage. The grid connection is arranged so that electricity generated supplies the needs of the site, only exporting to the grid when there is a surplus.

The total project budget was £70,000. Sowing Seeds provided £31,213 but the process from initial agreement to receipt of the grant took 3 years. This is one of three hydropower projects in the area in receipt of the grant, all using different hydro turbine technologies.

Bindon Mill Screw Turbine Installation

Hydropower renewable electricity generation project at Bindon Mill in Dorset.

Nature of Prioject
A 20 kW screw turbine was installed at the historic mill site of Bindon Mill. The site is on the River Frome near Wool on the Lulworth Estate. The estate has a record of good environmental stewardship. The installation of this renewable electricity generation is estimated to generate 77,000 kWh/yr saving 40 tonnes of carbon dioxide a year making the site a net exporter of electricity to the grid and providing an income to the Lulworth Estate from the Feed in Tariff and sales of electricity.

A screw turbine was chosen to match the low head, high flows and requirement for fish protection at this site. The rated flow of the turbine is determined by the flows available and the limitations imposed by the grid connection. At this site, Scottish and Southern Power stated a maximum of 20 kW could be put into the grid. To comply with the Environment Agency Good Practise Guidelines, a 2.2 m diameter turbine, taking a maximum flow of 2.080 m3s was chosen.

The project included improvements to the existing fish ladder around the mill to facilitate better passage of salmon and trout for this environmentally important river. The turbine channel and turbine house were sensitively designed to blend well with existing building at this historic mill site.

Approach
Extensive negotiation with the Environment Agency, Natural England and Purbeck District Council was required to ensure that the scheme design and methods of construction complied with the environmental standards expected to achieve the necessary Abstraction License, Flood Defence Consent and Planning Consent.

It was decided to install the turbine in a new channel between the river and the exit to the fish ladder so that fish attracted to the turbine outflow would be able to make their way up the improved fish ladder. The fisheries research centre at East Stoke have installed fish counters to monitor the effects. To get the very heavy excavation and turbine delivery vehicle to site required the construction of two temporary bridges across the river and a parallel channel.

The turbine house above the top of the turbine houses a grid connect and control box that controls the flow of water through the turbine so that there is always enough flow in the river and fish ladder to ensure that fish can move up and down river. The grid connection is arranged so that electricity generated supplies the needs of the site owner’s residence, only exporting to
the grid when there is a surplus.

Postscript
There are numerous old mill sites and other potential hydropower sites in Dorset. The Feed in Tariffs, sales of electricity and avoided import of electricity make development of these sites financially attractive. Project management is not beyond the scope of a talented amateur but the complexity of the design and license application process means that expert
advice is usually required.
