During the last few months the Evance R9000 small wind turbine has undergone further tests which have confirmed its energy generation has increased by over 4% to 9,167kWh at a wind speed of 5 metres per second.

The R9000 5kW turbine was one of the first small wind turbines to be fully certified under the Microgeneration Certification Scheme (MCS) in July 2010, and since then has received system improvements.

Many Evance customers have already benefitted from higher than expected energy generation as the R9000 system improvements were implemented several months ago. For example, Clive Breeze was pleasantly surprised with the energy generated from his recent installation: “Inthe first three weeks alone, the R9000 turbines exceeded the predicted energy generation targets by 10 percent and the first quarterly electricity bill showed a reduction of over £300 per month.”

“We’re delighted that our R9000 turbine is proving so efficient in energy production as this translates directly into a faster return on investmentfor our customers,” said Kevin Parslow, CEO of Evance Wind Turbines. “We design and manufacture our turbines here in the UK, so our customers are quick to benefit from any improvements that we make.”

“Our R9000 machine accounted for a third of all small wind turbines sold in the UK last year – making it the UK’s small wind turbine of choice. We look forward to maintaining our leadership position as we continue to develop our renewable energy system offerings,” concludes Kevin.

Micro-generation covers small scale generators where customers can generate their own electricity and export the surplus back to the grid. Microgeneration technologies include small scale wind turbines, hydro turbines and solar photovoltaic systems.

New clarifications may issue in due course on the new Terms and Conditions, if deemed necessary.

Over the past few months the children of Scoil Naomh Maodhóg in Ferns, Co. Wexford have been busy collecting two litre plastic bottles to construct their latest eco-friendly project. The bottles have now found a new lease of  life as the school’s eco-friendly greenhouse.

The lids and labels were removed and the bottoms were trimmed to allow them to slot into each other to create a long tube. The tubes were then stacked side by side and secured into the timber  frame with wires spaced at intervals up the frame and roof.  The wires hold the bottle in place and it is the cross tie wire that binds it into a solid wall, closing most of the gaps.

This is the perfect project for schools as it is a great re-use educational structure that really works.

The school has a ‘green’ ethos that is to be admired and is working towards becoming a more environmentally friendly and sustainable school.  School projects to date include the creating of  raised flower and vegetable beds, wildlife garden and pond, a  newly planted woodland area, the erection of bird boxes, butterfly boxes and an insect hotel that are all tended by the children. They make their own compost and water the plants with the rainwater they collect.

The children are introduced to growing their own vegetables. They plant the seeds and wait patiently for them to germinate.  They are then planted out when weather permits and  each class take turns to water and keep them weed free. There is great excitement when its time to harvest the produce as they get to divide it and bring it home.

Last year the potatoes were harvested and the children cut them into chips. They were then brought to the local diner to be cooked. A very tasty meal was had by all!

Pond and wild flower garden

Along side the pond the children have planted a variety of nectar producing plants and shrubs to encourage butterflies and other nectar loving insects into the garden. Rough grass margins have also been successfully established and this provides an excellent habitat for many insects and is ideal for the newly-emerged frogs that are a great attraction for the children every year.

Native tree nursery

Last year the school  began the task of extending the existing Woodland area. It was decided to plant only native species to the area  so the children brought in tree sapplings from their own gardens and created a nursery. When they were strong  enough they were planted out in the well prepared area. Their aim is to create natural habitats so as to introduce various insects, butterflies and birds into the school grounds. The children have great fun walking through the Woodland, turning up stones and wood to see what insects are lurking beneath.

Last year a Tidy Towns Junior Committee was formed. They are a great asset to the community as they are involved in keeping the school litter free, promote energy efficiency and recycling and reusing in the school. They were also involved with the development of the Community Park.  They were presented with an Endeavour Award  in recognition of their great work and achievements. They are busy planning some very exciting projects at the moment which are so top secret thet they won’t even divulge the details to the Ferns Tidy Towns Committee. May just watch this space!

It is one of the most energy efficient schools in the area. Over the years the school has taken on projects such as upgrading their insulation, installing new windows and replacing incandescent light bulbs with energy saving light bulbs. The children have a great awareness of energy saving. Simple measures like turning off lights and closing doors when leaving a room help to conserve energy.

The farm of Focus Farmer Eoin McCambridge recently played host to a large group of farmers for a workshop on micro-hydropower.

Nigel Moore, CAFRE, and Eoin McCambridge, Focus Farmer (centre) with John Henderson, Ballykelly and Liam Corry, Castlederg, who attended a CAFRE workshop on Energy from Micro-hydro on Eoin’s farm near Ballycastle recently.

In a suitable location small-scale hydropower is one of the most cost-effective and reliable of the renewable energy technologies.   It has several advantages over wind and solar power, with a high level of predictability, varying with annual rainfall patterns. It is a long-lasting and robust technology and systems can readily be engineered to last for 50 years or more.

Those attending were given an understanding of the principles of micro-hydro, connecting to the Grid and the economics of potential systems. Eoin was then able to demonstrate the plant on Ballynalough Farm.

For those  interested in energy from micro-hydro and other renewable technologies, DARD, in conjunction with the Ulster Farmers’ Union  and Agri-Food and Biosciences Institute are running another Practical On-farm Renewable Energy Event, this time at CAFRE’s Enniskillen Campus on Wednesday 22 February from 1.30pm through to 10.00pm.

The Fair is open FREE of charge to anyone in the farming and rural sector who are interested in reducing their costs through adopting more energy efficient practices and will provide a platform to network, source, meet suppliers and keep up-to-date on energy-saving systems and renewable technologies.

There will again be a series of seminars throughout the day on each of the main renewable energy technologies; wind power, biomass production and utilisation, anaerobic digestion, solar hot water, micro-hydro, and heat pumps.

A second series of seminars will deal with many of the issues facing those considering a green energy source. Topics covered will include the proposed Renewable Heat Incentive (RHI), grid connection, planning, NI Renewable Obligation Certificates (NIROC’s), business planning, taxation, as well as finance and funding options.

In addition there will be a Trade Exhibition and the opportunity to see the biomass boiler installation at Enniskillen campus. For further details contact Connor Maguire at 028 6634 4853 or connor.maguire@dardni.gov.uk

Hydro projects in Northern Ireland: 

The first ever Archimedean Screw generator in Northern Ireland was only recently installed at Shane’s Castle in Antrim. Rated at 214 kilowatts this is the largest single Archimedean Screw generator ever manufactured. It is now fully commissioned  fully operational.

The predicted annual output is a massive 1,125,000 kilowatt-hours. To put this in perspective, an average household uses less than 5,000 kilowatt-hours per year, so this hydro scheme has the potential to power more than 225 houses. This scheme will also save an impressive 484 tonnes or more of Carbon Dioxide (CO2) emissions by generating clean, green electricity.

Shane's Castle Hydro Project, Antrim

Omagh District Council  are  utilising the weir on the Camowen River, adjacent to Omagh Leisure Complex, to generate electricity through an Archimedean Screw hydro turbine. This hydro project is the second of only two Archimedean Screw hydro projects to date in Northern Ireland. The development of the hydro scheme on the Camowen River will generate sufficient power to meet the needs of Omagh Leisure Complex with excess electricity sold back to the national grid. Rated at 121 kilowatts the hydro turbine is predicted to save in excess of 133 tonnes of Carbon Dioxide (CO2) annually. It is expected that this project will be fully commissioned and operational in the coming weeks.

We look forward to meeting you at the show.

We offer a friendly one-stop shop for hydro development, from feasibility studies to licensing, to installation and commissioning and everything in between.

Last week’s violent Atlantic storm brought extremely high winds to the West and North of Scotland, with the Met Office recording maximum wind gusts of 165mph on Cairngorm Summit and 145mph at Aonach Mor.* The Met Office issued its strongest warning – a red alert – for winds in Scotland, and people were warned to stay indoors, schools were forced to close and flights were cancelled.

For owners of Evance R9000 small wind turbines, however, Scotland’s extreme wind speeds didn’t present any challenges. The Evance R9000 turbine is designed to keep running in the highest winds, and features an innovative Reactive Pitch™ mechanism that automatically pitches the turbine’s blades so it can regulate energy capture and blade speed.

Evance has over 50 of its R9000 turbines installed in the Orkney Islands. All continued to perform well during the storm, confirming the applicability of small wind turbines even in these most extreme conditions.

One Evance turbine owner, Adam Cockram, lives on Eday – one of Orkney’s Northern Isles – where peak gusts of over 130mph (58 metres per second) were recorded. According to Adam: “on Thursday night and Friday morning last week the wind gusted at up to 138mph. I did wonder whether our Evance turbine would keep going, and I’m glad to say that there were no problems at all!”

“Like many in Orkney we experienced several mains power failures. Each time the turbine started back up with no problems at all,” continued Adam. “I’m certainly impressed by the quality of both the Evance turbine and the installation carried out by Orkney Micro Renewables. It’s certainly been tested here on Eday!”

Adam Cockram’s Evance R9000 turbine was commissioned in August 2011, and in five months has already produced 7,343kWh of electricity.
