Cragside Estate

The world’s first home to be lit by hydroelectricity is once again being powered by water following the installation of a new Archimedes screw turbine at England’s Cragside estate.

Lord William Armstrong first begin using water from the estate’s five lakes to generate power in late 1870s, bringing Cragside’s story full-circle, according to the National Trust, which has curated the site since 1977.

“Lord Armstrong was an exceptional man with an ingenious mind, and the prospect of bringing his vision for Cragside into the 21st Century is a dream come true,” property manager Andrew Sawyer said. “Hydroelectricity is the world’s most widely used form of renewable energy, so we are looking forward to sharing this very special part of its heritage.”

Water for the new Archimedes screw will be drawn from Tumbleton Lake, which is the lowest of the estate’s reservoirs. The water will turn a17-meter long galvanized turbine that will produce about 12 kW of energy, or, the National Trust said, enough to power all of Cragside’s 350 light bulbs over the course of a year.

The organization said it chose an Archimedes screw design not only for its ability to generate power at a low speed, but for its ability to allow for safe fish passage.

“The best thing about the screw is that it’s visible, and we hope this will add to people’s understanding of why Cragside is so special,” said Sarah Pemberton, National Trust Head of Conservation for Yorkshire and the North East. “It not only makes economic sense, but adds so much depth to the story this special house has to tell.”

The Cragside project is part of the National Trust’s initiative to power each of its 43 historic properties with renewable energy.

About kingstonrenewableenergy

Kingston Renewable Energy (KRE), Hydropower products, wind energy, renewable energy products, We manufacture, supply and install. Richard Kingston KRE is the home of Fluxy, a beautiful Irish made wind turbine designed to last several life-times, and a host of other Hydro products branded under KRE hydro. KRE HYDRO- KRE are currently installing a range of Hydro products including high head low flow systems and low head high flow. These are pelton and Turgo types for high head, crossflow Banki turbines for medium to low head and Powerpal for Ultra low head. We also plan to introduce a custom timber/steel/aluminium waterwheel service for those of you who are lucky enough to have disused mills on their land and who would like to restore them to their former glory (and make a healthy profit in the process). All hydro installations are custom designed. This is necessary because everybody's land and water resource is different and to benefit from the highest efficiency and lowest payback time the hydro system must be customized according to what flow, penstock length required, and what head is available. Hydropower is currently by far the most cost effective renewable resource in Ireland under the existing Feed in tariff structure and export rate of 9c per unit (wholesale rate for bigger systems is €0.087/kWh). It is surprising how much energy is to be harvested from even a small stream and we are offering 4 to 7 year payback times on average and high profits thereafter. KRE FLUXY- It has been a long journey from when I originally set out to buy a wind turbine to power my own house in 2007 and discovered that the existing machines on offer in the market failed to meet my desires as a customer; that is, to possess an aesthetically designed machine with a low embodied carbon footprint and a long design lifespan. This led to my resolve to make this a possibility as I knew there were other like minded folks out there who had the same needs when buying into renewable energy. I have always been a keen environmental activist and had a strong understanding of engineering and material sciences which enabled me to see failings in the high tech electronically controlled machines commonly available today. These weaknesses come from over complicating the wind system with servo motors, sensors, gear trains, relays and logic circuits; fine for large utility scale turbines which are constantly monitored and have continual maintenance on site but not for a small wind turbine in the back yard to run the house. I could see that wind turbines needed to be brought back to a less complicated yet modern design that would withstand time and the turbulent and violent winds we see in Ireland and fulfilling the old engineers adage of ‘KISS’ or ‘keep it simple stupid’. With less component parts, there are less things to go wrong. My vision was to create a machine that offered the benefits of being an economic investment, a positive for the environment and also to be a design piece that our customers are proud to have flying in their grounds. And so, I present you with the fully mechanical Kingston Renewable Energy Fluxy wind turbine. Please feel free to contact us at any time if you have any questions or think you may have a good wind site. We will happily do a site assessment come rain or shine. Stay posted for the monthly blogs from our inspirational team here at KRE. Check out our latest installments in our crusade to get higher feed-in tariffs in Ireland so that we can compete with the rest of Europe in the micro-generation stakes. The Hydro section of our website will be updated shortly to show our newest installations and showcase our products. Yours sincerely, Richard Kingston
