Exmoor Planning Success

Posted in News on Tuesday 6th March 2012 at 10:28pm

WRE has been working for some time on a hydro scheme on the River Barle, a large tributary of the Exe.  Today permission was unanimously granted for a 78kW hydro plant on the river at Dulverton.  This system will be a reinstatement of a hydro scheme dormant since the 1950's.  The owners of the site have worked tirelessly to develop a proposal which includes the best practice available at this sensitive site.  The prospect of vastly improving the passage of fish past the site is to be welcomed, and the renewable power produced will mean that this is absolutely a 'win-win' site. 

We look forward to seeing this site become an exemplar of sustainability within the National Park.

WRE has just completed a small hydro scheme in South Devon.  The scheme incorporates 6mm fish screening, a spacious powerhouse, and a compact crossflow turbine operating on 180l/s and 4.5m head. 

The system is simple, fully automated and quiet in operation.  The layout is typical of many smaller mills, and whilst elements of the historical systems were used, most of the system was new.

River Dart hydro scheme

Posted in News on Wednesday 4th January 2012 at 12:29am

WRE is currently installing another hydro scheme on the River Dart, immediately downstream from the first screw turbine on this river (installed by WRE, Castleford engineering and GP Electronics in 2006).  The system includes a fishpass and is the biggest flowrate turbine in the Dart system.  WRE is based at Old Walls on the West Webburn river which is the largest output hydro plant now in the Dart catchment, this plant when added to WRE designed and installed plants at Ashburton, Buckfast, Poundsgate and Dartington brings the installed capacity to around 230kW.  For some historical benchmark, around 1950 there was about 700kW of hydro on the Dart, but by 1980 this had dwindled to a small fraction of this, the current renaissance is therefore only partially regaining lost ground, and the total possible capacity is actually many megawatts, if as a society we were reasonably committed to hydro.

Construction Updates

Posted in Projects on Tuesday 4th October 2011 at 10:22pm

WRE is currently installing a new 23kW crossflow turbine at a site on Dartmoor.

The system is equipped with an advanced control system which can be operated via the internet, and controls not only the turbine itself, but also ancillary equipment such as the screening equipment.  This type of control system is increasingly being deployed on even moderate schemes to maximise output and minimise downtime.

It can also make operation and maintenance by WRE more straightforward.

The largest screw turbine hydro system operating on the Thames, designed by WRE has generated successfully.  The system uses 8 cubic metres of water per second, on a 1.7m head, and is the largest flow screw turbine operating in the UK.

The system was challenging because it was built so close to the existing historic mill building.

Summer Update

Posted in News on Friday 29th July 2011 at 12:22am

The low flows which have been evident all year have allowed WRE to make good progress on a number of sites, and we currently have over 250kW of sites under construction.  The WRE designed system at Mapledurham is developing well under the watchful eye of Greenfords, and the Rehart turbine will be delivered soon.  This is the largest flow of any screw turbine in the UK, and should be operating during October.  In addition WRE is working at two mill sites in Devon, one near Chagford and one near Dartmouth, with a capacity of around 30kW in total, both to be equipped with Ecowave crossflow machines.  A significant project at Buckfast Abbey on the Dart is just commencing, with the screw turbine recently ordered from Ritz-Atro for this site, and is the largest power output turbine from this company installed in the UK to date.

Coupled with this, a significant number of other sites are moving forward, meaning that whilst we will comission more capacity in 2011 than ever before, we are confident that 2012 will result in even more capacity

Leaves, leaves everywhere, and a lot of water to drink

Posted in News on Monday 15th November 2010 at 9:40am

The eight hydro schemes which WRE regularly maintains for clients in Devon and Cornwall have been generating at maximum capacity recently, although these last few weeks have brought massive volumes of leaves and debris as well. This has meant extra work for the screening systems, but when there is so much water available it is important to keep output at maximum. It is good to see water levels up, after what has been a fairly dry early part of the year.

WRE’s directly employed construction team are just completing a system at Cotehele for the National Trust, and the good standard of finish required by the trust is evident on this site. We look forward to the handover, and adding the site to our list of operating sites. At the other end of the country, another scheme designed by WRE is taking shape. The Bainbridge hydro system in the Yorkshire Dales was designed by us, and is being built for the community based owning group by contractor A E Yates, with h2oPE as project managers. WRE looks forward to further involvement at this site in the new year. Elsewhere WRE are acting as lead consultant for a screw turbine project in Rochdale. The client, GMPTE, is developing a new transport interchange, and WRE has developed the proposal for a turbine and fish pass at the site over the last eighteen months. The development is now under construction as a design and build project under the auspices of Spaans Babcock, with WRE regularly on site coordinating between the client and contractor. Meanwhile at sites from Dartmoor to the Peak District small systems are being installed, with the owners carrying out much of the actual construction, with WRE designing it, and installing the powerhouse equipment under the MCS process.

These projects demonstrate that WRE is able to help clients in a range of professional roles, from design and construction with our in house team, to complete system design with construction put to tender, or high level coordination of projects delivered via design and build methods.

Which is the best route to take mainly depends on the client, and there is a broad range in the industry, WRE believes that our independence and flexibility is a key benefit.

October Updates

Posted in News on Friday 1st October 2010 at 10:45am

MCS

WRE is pleased to announce it is now listed as an MCS transition installer, and this allows us to design and install systems to receive the Feed-In-Tariff, and as such we will fully commission three schemes in the next month.  Sub-50kW systems designed or installed by a non-MCS installer will not be eligible for the FIT.

Installations Update

WRE has recently ordered a second turbine from Ecowave Systems, a crossflow turbine to operate on 25m head on a site on Dartmoor, which should be generating in December.  This system is designed by WRE.

Screening Equipment

We have also supplied further Coanda type screens, as well as gaining future orders for more.  We have recently sold 10mm screening systems to fellow hydropower system designers Renewables First and Highland Eco Design for low head sites, and are about to start delivery of similar systems to the 6mm standard sometimes requested by the EA.

August Updates

Posted in News on Thursday 12th August 2010 at 5:19pm

As so often, whilst the summer brings mixed weather for tourists in the Westcountry, WRE is hard at work making use of the drier weather to carry out construction of hydro schemes.  We are working at two sites, one for the National Trust, is just starting, and another for a private client is moving toward completion.

The private client has carried out most of the works himself, with WRE doing design and specification of the system, and fitting and commissioning the system.  The turbine is a very neat and compact machine from Ecowave Systems, which has been specified as it offered a small and quiet machine, at a good price from a UK supplier.  Pleasingly the delivery was relatively fast, and we will report on the performance of this model, as it is the first from this manufacturer that we have installed.

The National Trust site is at Cotehele in Cornwall, and despite wet ground conditions and difficult access (as ever), progress is good.  WRE has designed and gained licenses for this site, and is doing all the installation and commissioning, in the coming months. This system uses a sturdy JLA turbine.

Further work for the National Trust is continuing, with progress on sites in the Westcountry, hopefully which will lead to installation in 2011/12.

Work for later in the year covers Screw, Crossflow and Pelton systems, with potentially hundreds of kW of installed capacity following in the next 12 months.

Look out for the website updates shortly.

Hydro scheme, River Otter, Devon

Posted in Projects on Friday 7th May 2010 at 4:41pm

WRE has recently started construction of a 28kW hydro plant at Tipton St John in East Devon.  After a long licensing process, including a successful appeal a license was issued in June 2009.  The development has been assisted by the East Devon AONB Sustainable Development Fund, which provided significant assistance in moving the proposal through the long design process  Unfortunately, due to the tight restrictions on timing it was not possible to start construction until 2010.  However, after receiving the necessary Flood Defence Consent, Planning Permission, and carrying out the necessary ecological work, fish rescue and agreeing to the archaeological conditions, preparatory work finally got underway this week.  The undergrowth has been cleared, and the leat dredged, and with good ground conditions and weather concrete will be poured in the next couple of weeks.  Commissioning is anticipated to be in August, water flow permitting.
