Electricity pylons to be removed from protected landscapes

Plans to reduce the visual impact of electricity infrastructure in nationally protected landscapes across England and Wales have reached a new landmark, following decisions by the project’s independently chaired Stakeholder Advisory Group.

In November 2014, twelve sections of high voltage lines in eight Areas of Outstanding Natural Beauty (AONBs) and National Parks were shortlisted as having the most significant landscape and visual impact, following a study overseen by leading landscape expert Professor Carys Swanwick.

Since then, National Grid and independent landscape consultants have done further technical work with considerable and highly detailed input from local stakeholders in each location. This has enabled the Stakeholder Advisory Group to prioritise four projects from the shortlist.

The Stakeholder Advisory Group’s decisions were made after a rigorous review of each shortlisted section of line. Members at a two-day meeting considered each project using a set of five guiding project principles from the Visual Impact Provision project’s policy.

These four projects will be taken forward over the next 12 months for detailed technical feasibility works which will include environmental studies, archaeological studies and engineering work ‘on the ground’. There will also be further significant engagement with local stakeholders and communities.

National Grid transmission lines which have been prioritised in protected landscapes are:

  • Dorset Area of Outstanding Natural Beauty near Winterbourne Abbas
  • New Forest National Park near Hale
  • Peak District National Park near Dunford Bridge
  • Snowdonia National Park near Porthmadog

Using a £500 million allowance made available by Ofgem until 2021, National Grid plans to reduce the visual impact of sections of high voltage overhead lines in these locations. A range of different ways of doing this has been considered in each location.
Given the sensitive nature of these protected areas, replacing existing overhead lines with underground cables has generally proved to be the preferred option both technically and in discussion with local stakeholders.

Chris Baines, Chair of the Stakeholder Advisory Group, said “Reducing the visual impact of pylons and power lines in our most precious landscapes is highly desirable, but it is also very expensive and technically complex so we have had to make some difficult decisions. Although four schemes have been prioritised, none of the locations on our original shortlist have been dropped and they will remain under consideration for future work to reduce the impact of National Grid’s transmission lines under the Visual Impact Provision project.”

Hector Pearson, Visual Impact Provision Project Manager, National Grid, comments “This is a unique stakeholder-driven project, and it continues to represent a major opportunity to conserve and enhance the natural beauty, wildlife, cultural and environmental heritage of some Areas of Outstanding Natural Beauty and National Parks. We will continue to work in partnership with stakeholders to not only mitigate the impact of our transmission lines in these areas but to also enhance the landscape, and deliver value for money.”

The Stakeholder Advisory Group is chaired by environmentalist, Chris Baines and comprises senior representatives from organisations including the Campaign for National Parks, Campaign to Protect Rural England, Campaign for the Protection of Rural Wales, Historic England, Cadw, Natural England and the National Trust. It was established to help National Grid identify which transmission lines should be prioritised to make use of the £500 million allowance.

The protected landscapes that have not been prioritised are the Brecon Beacons National Park, High Weald AONB, North Wessex Downs AONB and the Tamar Valley AONB. These locations will remain under consideration for future work using the VIP allowance.

National Grid is also set to use part of the £500 million for smaller localised visual improvement projects which can be accessed by all AONBs and National Parks with existing National Grid electricity infrastructure.

Set to be launched in the Winter, this landscape enhancement initiative will to provide up to £24 million over six years. The aim will be to reduce the visual impact of National Grid’s existing infrastructure in AONBs and National Parks and improve the related visual quality of the landscape. A range of local visual improvement projects could enhance biodiversity, benefit cultural heritage or raise awareness of natural and historic features of a landscape.

New scheme launches to power office buildings… with coffee!

Coffee shops fuelling Londoners’ morning caffeine fix will also be helping to power office buildings and supermarkets, under a new capital-wide scheme.

The innovative coffee ground collection service is the brainchild of advanced biofuel company bio-bean, previous winners of the Mayor of London’s inaugural green technology Low Carbon Entrepreneur Award. They will turn the waste coffee grounds collected from London baristas into advanced biomass pellets, which will then be used to power energy networks with the capacity to heat up to 15,000 homes. The support and funding from the award has helped to turn founder and chief executive Arthur Kay’s green idea into a viable, now nation-wide business, employing over 20 people.

Mayor Boris Johnson called on more students to get involved in London’s thriving green economy and submit green business ideas as he launched the 2016 Low Carbon Entrepreneur Award with a top prize of £20,000. He was joined by Mr Kay at independent coffee shop Workshop Coffee in Clerkenwell, one of hundreds of coffee shops, office blocks and transport hubs in London now part of the daily coffee ground collection service run in collaboration with recycling company First Mile.

The competition has helped many university students launch green businesses including SolarBox, which turns disused telephone boxes into solar-powered mobile phone stations, and online clothes-swapping website Clotho London. The value of the green industry to the city is already as much as £30 billion a year and it employs 160,000 people, growing throughout the recession and now at a rate of six per cent a year.

Mayor of London Boris Johnson said “Our green economy is booming and I want the next generation of Low Carbon Entrepreneurs to help make London the greenest, most sustainable innovative city on earth. The roaring success of previous winners like Bio-bean demonstrates the huge market for green technology ideas. They’ve done the hard grind and Londoners can now enjoy their daily coffee fix in the safe knowledge that as well as their own caffeine kick the energy levels of as many as 15,000 homes are being boosted!”

Bio-bean is the first company in the world to industrialise the process of recycling waste coffee grounds into advanced biofuels. Their factory has the capacity to process 50,000 tonnes of waste coffee grounds each year, the equivalent of one in every ten cups of coffee drunk in the UK, and at full capacity turn these into enough power to heat the equivalent of over 15,000 homes. Furthermore, as well as saving money for customers, each tonne recycled through bio-bean’s process saves up to 6.8 tonnes of CO2 equivalent. Bio-bean has already secured a deal with Network Rail to collect waste coffee grounds from London’s seven largest train stations and has plans for even greater expansion.

Bio-bean chief executive Arthur Kay said “The first ever Low Carbon Entrepreneur Award gave me (and bio-bean) a great start. The London collection service marks a milestone in our UK development, as we collect waste coffee grounds at every scale, saving money on waste disposal fees and creating sustainability advantages for each of our clients.”

This year’s awards will be sponsored by Citi, the global banking group, and will offer £20,000 and paid internships at Citi in the UK, where the bank employs almost 10,000 people. 10 finalists will pitch to a panel of well-known judges in ‘Dragon’s Den’ style and the winners will receive funding to put towards their business idea. The competition is an important part of the Mayor’s vision to make London the European capital for green technology and to also nourish young entrepreneurship. Awards are open from today until February 2016. Entries can be made in a number of different categories, including transport, energy efficiency, product design and food waste.

Michael Lavelle, head of Corporate and Investment Banking, UK at Citi, said “We’re thrilled to be the new sponsor of this important initiative in London. At Citi, we are committed to developing innovative ways of financing projects that lead to sustainable growth. We recently announced that Citi will lend, invest and facilitate a total of $100 billion within the next 10 years to finance activities that reduce the impacts of climate change and create environmental solutions that benefit people and communities.”

The Old Oak and Park Royal Development Corporation is currently exploring how it could deliver the Mayor’s aspiration for a clean tech cluster to be developed on site, which could allow businesses in the sector to work together in close proximity similar to the ‘silicon roundabout’ for tech companies in east London. This could support businesses to maximise the benefits generated by the new High Speed 2 (HS2), Crossrail and Great West Main Line interchange, which will be situated in the area.

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.”
