Bauder delivers largest solar array in higher education sector

The University of the West of England (UWE) in Bristol has recently quadrupled its solar generating capacity through the installation of 1,731 solar panels, which will enable it to produce over 400 MWh of electricity each year and making it the largest solar panel array in the UK university sector.

The new solar array has been installed on the roof of the University Enterprise Zone (UEZ) and the Bristol Robotics Laboratory, which have both undergone extensive refurbishment as part of the required works. Prior to the solar panels being installed, approved contractor Mitie Tilley Roofing overlaid the original failing single ply waterproofing with over 12,000m2 of Bauder’s lightweight, robust PVC single ply waterproofing system Thermofol. The solar modules, which weigh just 12Kg/m2, were then fitted onto the waterproofing using a unique penetration-free, welding method by renewable energy specialists Dulas. This installation technique means that the roof is not compromised by penetrations for fixings nor is it ballasted, which would add additional weight loading to the roof.

The new photovoltaic system will generate at least 74.32 Megawatt Hours of solar power each year which should; cover half of the energy consumed within the building, save around 200 tonnes of carbon and provide annual savings of over £50,000 a year. The university is highly committed to sustainability and energy efficiency, and this solar project is just part of a much wider plan to achieve its carbon reduction goals and enhance local renewable energy capacity.

Fabia Jeddere-Fisher, Energy Engineer at UWE, stated, “From its conception, we chose a roofing system that would mean the flat roof would not need to be strengthened if we chose to add solar panels. Normally, panels placed on flat roofs require either weighing down or fixings that penetrate the roof membrane, which can introduce the risk of leaks. The system we have chosen means that the panels are welded into place, reducing load, and reducing the need for roof penetrations. The University will use 100% of the power generated by the PV array, which will be equal to the amount generated by nearly 200 homes with solar panels. As a large organisation we want to set an example for others to undertake similar projects.”

Solar PV plant to be built in Chernobyl Exclusion Zone

Two Chinese firms have announced that they intend to rejuvenate Chernobyl’s exclusion zone by building a solar PV plant within its confines.

GCL System Integration Technology Co., Ltd. (GCL-SI) , a subsidiary of the world’s leading energy group GCL, will cooperate with China National Complete Engineering Corporation (CCEC) in delivering the Chernobyl PV plant project thirty years after the Chernobyl accident.

On 26th April 1986, during a safety check, reactor 4 of the Chernobyl power plant experienced a meltdown that could not be contained. As a result, it is estimated that more than 100,000 people have died as either a direct result of fallout or from subsequent radiation-related illnesses. It is also estimated that over £111.7 billion worth of damage was caused by the disaster. These astounding figures prove that regardless of who is considered responsible for the accident, cleaning up Chernobyl is of worldwide concern. If another reactor had blown during the meltdown, Chernobyl could have rendered the whole of Europe uninhabitable.

During the meltdown, vast quantities of radiation were released into the surrounding atmosphere, contaminating approximately 30 km2 of land with fallout. However, the Ukrainian government now aims to give a new renewable life to the exclusion zone. In October, the country’s Ministry of Environment and Natural Resources claimed the plan to build a PV plant at Chernobyl. “Its cheap land and abundant sunlight constitute a solid foundation for the project. In addition, the remaining electric transmission facilities are ready for reuse,” said Ostap Semerak, Ukraine’s minister of environment and natural resources.

Two Chinese companies will play significant parts in Chernobyl’s revival. CCEC are the general contractor and will manage the overall project. GCL-SI will offer consultancy and planning service as well as PV facilities to the project. According to GCL-SI, construction of the over 1 GW PV plant is expected to initiate in 2017. Once completed, Chernobyl will once again catch the global attention; this time as a revived site of solar energy.

“There will be remarkable social benefits and economical ones as we try to renovate the once damaged area with green and renewable energy. We are glad that we are making joint efforts with Ukraine to rebuild the community for the local people,” said Mr. Shu Hua, Chairman of GCL-SI.

Regarding GCL-SI’s overseas strategy, Mr. Shu further commented: “We have been dedicated to providing integrated solar services and will take diverse approaches this year to drive penetration and achieve global presence. The Chernobyl project is also one of our key steps to approach abroad.”

Hinkley Point C delayed – meanwhile renewable energy outperforms coal in new statistics

Controversial plans to construct a nuclear power plant in the UK have been delayed following the government postponing any final decision until early autumn. Meanwhile, new official UK electricity statistics indicate that renewable technology is currently outperforming coal in terms of energy generation.

Prior to today’s announcement that the project would be delayed, French firm EDF were financing the majority of the £18bn Hinkley Point C project in Somerset, and final contracts were due to be signed this week.

However, Business Secretary Greg Clark has now said that the government will have to “consider carefully” before backing the original plans.

The project has raised serious concern over both environmental impact and ever-rising costs, which make it a costly carbuncle rather than a real asset to Britain. There are also questions being raised about the fact that the plant is being built by foreign governments. For example, around 30% of the £18bn cost is currently being provided by Chinese investors.

Stop Hinkley Spokesperson Allan Jeffery commented “Now even the financial press says Hinkley Point C has become a laughing stock.

“The cost keeps rising while the cost of renewables is falling rapidly, and the potential to make savings with energy efficiency is huge. We could replace Hinkley much more quickly and cheaply without the safety fears and without producing dangerous waste we don’t know what to do with.”

Renewables

In other energy news, the Government’s new annual energy statistics show that renewable energy sources are replacing coal as mainstream technologies generating power for British homes, offices and factories.

Renewables-BS-article

Today’s figures confirm that 25% of the UK’s electricity was generated from renewables last year – an increase of 29% on 2014. Nearly half of this (48%) came from wind power alone. 1 in 8 units of electricity generated in the UK came from wind.

In comparison, coal generated 22% of the country’s electricity – down from 30% in 2014.

RenewableUK’s Deputy Chief Executive Maf Smith said “The Government took the right decision when it announced the phasing out of coal. Now we can see renewable energy filling the gap, replacing old technology with new. 2015 was the first year that renewables outperformed coal.

“A quarter of Britain’s power is now coming from wind, wave and tidal power and other renewable energy sources. Renewables are now part of our energy mainstream, helping us modernise the way we keep the lights on by building new infrastructure for the generations to come.”

The contribution of offshore wind grew by 30% in 2015, while onshore wind grew by 23%. The Department for Business, Energy and Industrial Strategy, which published the figures, said this was due to increases in capacity, load factors and higher wind speeds.

The Government’s latest poll on the public’s views on energy, the Public Attitudes Tracking Survey, was also published today. It showed that 76% of people support renewable energy. 70% of people also said renewable projects provide economic benefits to the UK.

Construction begins on Europe’s largest floating solar farm

Construction work has started on what will be the largest floating solar farm in Europe. Located at the Queen Elizabeth II reservoir near London, the project is part of a greater effort by Thames Water to source a third of its energy from renewable methods by 2020.

Once completed in March, the floating array will boast the impressive accolade of being the second largest of its kind in the world.

In excess of 23,000 panels will be floated on the surface of the reservoir water, generating enough electricity per year to power the equivalent of around 1,800 homes. Once complete, the finished array will cover around a 10th of the reservoir’s surface area – roughly the same area as eight Wembley-sized football pitches.

Thames Water has confirmed that the renewable electricity produced by the 6.3MW floating array will be used to power a water treatment centre nearby.

Energy Manager, Angus Berry said “Becoming a more sustainable business is integral to our long term strategy and this innovative new project brings us one step closer to achieving our goal – this is the right thing for our customers, the right thing for our stakeholders and most importantly the right thing for the environment.”

The installation will require over 61,000 floats and 177 anchors to keep the array above water and in situ, and is been delivered by solar energy company Lightsource.

Chief Executive at Lightsource, Nick Boyle commented that as an increasing number of industries quite rightly turn their attention to lowering their carbon footprint, the solar industry will need to develop new skills in order to ensure that future projects deliver maximum efficiency.

“There is a great need from energy intensive industries to reduce their carbon footprint, as well as the amount they are spending on electricity and solar can be the perfect solution. Therefore, constantly evolving new skill sets to ensure that all of our projects deliver maximum energy generation over the lifetime of the installation” said Nick.

Floating solar farms are considered an efficient way to maximise renewable energy generation in areas where land is scarce, by using the normally redundant surface area on reservoirs and lakes.

The largest floating solar array is currently under construction on a reservoir in Japan. Once completed, it will provide enough clean electricity to power nearly 5,000 households.

Advocates of the approach argue it can also reduce evaporation from reservoirs, while the cooling effect of the water is said to help improve output from solar PV cells.

News of the floating array follows the recent announcement that wind turbine towers are set to reach heights of up to 170m – almost as high as the Gherkin in London, in the near future. This shows that in the world of energy, renewables continue to power ahead in terms of growth and innovation.

World’s largest concentrated solar plant opened in Morocco

Morocco has launched the first phase of the largest concentrated solar power (CSP) plant in the world. When fully operational, the plant will produce enough energy for more than one million Moroccan households.

Inaugurated officially by His Majesty Mohammed VI of Morocco, the solar plant underlines the country’s determination to reduce dependence on fossil fuels, use more renewable energy, and move towards low carbon development.

The three-plant Noor-Ouarzazate CSP complex called NOORo expects to achieve over 500 megawatts (MW) installed capacity, ultimately supplying power to 1.1 million Moroccans by 2018. It is estimated that the plant will reduce the country’s energy dependence by about 2 and half million tons of oil, while also lowering carbon emissions by 760,000 tons per year.

Concentrated solar power is such a promising technology that the International Energy Agency estimates that up to 11 percent of the world’s electricity generation in 2050 could come from CSP. This is especially true in the Middle East and North Africa, a region with abundant solar resources and high hopes of eventually helping to meet the E.U.’s demand for energy.

“With this bold step toward a clean energy future, Morocco is pioneering a greener development and developing a cutting edge solar technology,” said Marie Francoise Marie-Nelly, World Bank Country Director for the Maghreb, “the returns on this investment will be significant for the country and its people, by enhancing energy security, creating a cleaner environment, and encouraging new industries and job creation.”

Despite the potential of CSP, relatively high technology costs, when compared to fossil fuel alternatives, deter utilities from investing. Concessional and public financing were key to lift this project off the ground. The Moroccan Agency for Solar Energy, the government agency focused on the country’s solar ambitions, secured over $3 billion needed for the Noor-Ouarzazate complex from the African Development Bank (AfDB), the Climate Investment Funds (CIF), European financing institutions and the World Bank.

“This launch shows that the low-cost, long-term financing provided by the CIF can serve as the spark that attracts the public and private investments needed to build massive CSP production facilities at an attractive cost for countries interested in developing solar energy,” said Mafalda Duarte, Head of the Climate Investment Funds.

Trailblazing projects on the African continent, like the Noor solar plant, are proving the performance of CSP. As well as the environmental benefits, the plant results in new, local jobs, and can lead to a high-performing sustainable energy economic sector for Morocco.

Yacine Fal, AfDB resident representative in Morocco, said “Noor solar complex is part of the innovative operations of AfDB in the energy sector in terms of financing and technology. It stands to serve as an example for Africa and the world about how to create effective pathways to greener and more inclusive economies through renewable energy”.

Queen Mary University Library Collecting Solar Energy

The library roof at the Queen Mary University of London (QMUL) had surpassed its natural life expectancy and been experiencing considerable water ingress, requiring urgent remedial work to prevent disruption to students.
In order to determine the most appropriate remedial solution the 2,000m2 roof area was surveyed by flat roof specialists Bauder, who proposed stripping the existing roof covering down to the structural metal deck and replacing it with a high quality and long lasting bituminous system. The client also decided to use this opportunity to make a positive and visible contribution to the university’s carbon reduction programme through the addition of energy producing solar panels. The library is the core study area for most students and is unsurprisingly one of the highest consumers of electricity out of all the campus buildings, so it seemed extremely appropriate that the PV would be situated there.
The main library roof and three connecting tank rooms were all waterproofed with Bauder’s premium bituminous system, BTRS, which is capable of withstanding permanently sited loads of up to 2000Kg/m2 and has a life expectancy in excess of 40 years. The system build-up included a highly efficient 120mm PIR FA-TE insulation for superior thermal performance, achieving the required 0.18 U-value. Tapered insulation was also used around the perimeter of one of the tank room roofs to effectively provide drainage falls without having to incorporate them into the structure.
Roof areas totalling 1,000m² were fitted with 126 monocrystalline PV modules, set at a 10 degree angle to optimise energy generation. The panels are expected to generate 32.43 MWh of energy within the first year and deliver CO2 savings of 17.155 tonnes, equal to 8,358 kg of coal burned. The PV system was installed using a unique drill-free technique that ensures the integrity of the roof is completely upheld; and the simplicity of this method also meant that roofing contractor, R T Roofing Services, could install the entire array in just two days.
One of the major challenges for this project was performing the required works on a busy campus and keeping noise levels to a minimum. To overcome this challenge the project team worked closely with the client to develop a work and delivery schedule; with many of the materials brought to site and unloaded at the weekend. Bauder also provided ear plugs for all library users to make sure that they weren’t disturbed from their work. Despite these logistical challenges, all roofing works were completed in time for the start of the new academic year and were undertaken as part of the university’s long term maintenance and regeneration programme.
Jennifer Raagas, QMUL Project Manager, stated her delight with the finished works at the university, “We are incredibly pleased with the work performed by Bauder and their approved contractors on the library roof. They have been extremely accommodating during an eventful summer period at the university, and their service has been of the absolute highest quality. Our new BauderSOLAR PV panels will not only help us generate our own solar energy but will also provide excellent research and learning opportunities for our students. With Bauder delivering a single source solution of roof renewal with PV install we have complete peace of mind over our roof’s guarantee and long-term future performance.”
