Towersey Festival

Towersey Festival worked with their power supplier Flying Hire to cut fuel use by almost a quarter across the site in 2018.

Flying Hire have provided power for Towersey for the last 4 years, each year working for greater efficiency, and pushing for the reduction of diesel. In 2018, a changed site plan gave the Flying Hire team the opportunity to work closely with Towersey to redesign their power plan, and achieve the significant fuel use reduction.

The new system involved building a miniature sub-station of synchronized generators and distributing all power from there; all the generators were synched on a load share demand basis for optimum running efficiency.

Planning was key to ensuring the transition would run smoothly; the team calculated the power needed around the main arena, the power being drawn, the load on cables and how this would affect the voltage. They reduced the number of generators from 14 the previous year to 8, and added an additional 3.2km of cabling in order to distribute the power. During the event fuel management for all the gen-sets was switched on and generators were monitored for optimum efficiency.

“For festivals that want to push on their green footprint, we would say work closely with your power provider and see how your setup can be made more efficient.” George Nearn, Flying Hire Ltd

Greenbelt Festival

Greenbelt Festival Aim for 100% Sustainable Power

Greenbelt is a weekend festival of ‘arts, faith and justice’ that has been running since 1974. In 2017 they had 11,000 people onsite for the 4-day event. Greenbelt has strong commitment to creating an environmentally sustainable festival by making their site more power efficient and looking for renewable sources of power.

After moving site to Boughton House, Northamptonshire, in 2013 they went from a festival site that was partially powered from the grid to one that required 100% onsite power. Initially they used diesel generators festival to power the site but they are now, “working towards a future when the festival is powered entirely from sustainable sources,” says Event Director Mary Corfield.

Helping the Greenbelt team on this journey is production company Judgeday and power supplier Gofer Ltd, who began working with the Greenbelt team in 2016 to help them achieve their sustainability goals around power. At the 2016 event they saved 2,000 litres of fuel and for 2017 they carefully planned their power needs saving a further 16% on fuel usage.

They achieved this through careful planning, understanding that, “data is knowledge,” they worked with their traders, suppliers, concessions and artists to get a clear picture of their expected power needs across the site. This knowledge allowed Gofer to model their event power use and create ‘power zones’, enabling them to reduce the size of generators, and in some cases clustering them together so that smaller generators could be used at times of low demand. They also continued to use LED festoon lighting and switched to LED floodlights to reduce power demand.

During the 2017 festival Greenbelt had two dedicated team members who monitored power use across the site to record power peaks and lows at different times of day and in different locations. This data gave them a practical understanding of energy demand throughout the festival and has allowed them to put energy efficiency plans in place for the next season with real confidence.

For the 2018 festival they are switching two whole areas from diesel to solar powered and two further areas will be powered with hybrid generators. They will replace half of their diesel tower lights with solar and the other half will be swapped for LED flood lights.

To reduce both transport costs and waste they rent an area on the site all year round to store staging, décor and furnishings. They have a policy of recycling and repurposing materials used in previous years and they have switched to generic (rather than year/theme specific) signage, which means they can be used year on year.

To further minimise waste Greenbelt has a re-usable cup scheme in their beer tents; their caterers use 100% compostable packaging work and food waste is collected and redistributed to local food bank charities. Greenbelt won a Greener Festival Awards in 2014, 2016 and 2017 for their environmental initiatives and they are part of the Vision: 2025 community of UK festivals who are working to reduce their environmental impacts. They also work with charity, Energy Revolution, to tackle the CO2 emissions associated with their audience travel by investing in projects that create renewable energy.

They have been recognised in the industry for their commitment to social inclusion and were awarded the Act of Independence award at AIF congress in 2017 for showcasing Muslim art and culture and platforming of Palestinian artists and activists. They hold the Gold Level on the Charter of Best Practice by ‘Attitude is Everything’ for their commitment to improving access for deaf and disabled festivalgoers.

The Greenbelt team believe passionately in the ability of individuals to come together and impact their communities and environment in a positive way; they plan to continue monitoring their environmental performance, innovating to find sustainable solutions, and sharing their experiences with the festival industry.

Cambridge Folk Festival

Relationship with Energy Supplier is Key to Reduction

Cambridge Folk Festival has been running since 1965, it takes place in July and has a capacity of 14,000. The Festival is committed to reducing the environmental impact of the event and have found that a strong relationship with their energy supplier, Pearce Hire, is key to reduction.

Cambridge Folk Festival have worked with Pearce Hire for over 30 years and they have come to understand the Festival’s environmental and ethical values. They work closely with the festival’s Sustainability Coordinator and the Production Manager, to continually improve on energy efficiency, introduce new innovations and to meet the criteria for the A Greener Festival accreditations, which the festival holds.

As Pearce Hire provide both power and lighting, they can invest in more efficient lighting, knowing that their investment will be subsidized by the resulting reduction in generator size and fuel costs. They are also uniquely placed to identify where and when to turn on/off generators and therefore save fuel.

Over the years they have introduced a number of innovations in lighting: adding photocells sensors, manufactured in-house, to switch site lighting on and off at dawn and dusk as required, resulting in huge savings in energy use and cost. They also swapped power-hungry tungsten floodlights for LED and festoon lighting site-wide, and supplied LED fixtures for stage lighting — next year they are looking to invest in some new LED profile moving head fixtures.

Generators used onsite are all Euro Stage Three compliant — one of the most energy efficient, low emission generators you can get and they are arranged in an efficient system of many smaller generators rather than two big sets. The festival is also partially run off mains electricity, supplied through a green tariff, which saves 12-15,000 litres of diesel per event and makes a massive saving on the carbon footprint. Meter readings are taken every three hours during the festival so that the carbon footprint can be accurately calculated and the festival’s major impacts can be identified and improvements made where necessary.

The Festival encourages all staff and vendors to ‘switch off ’ when possible; punters are asked to reuse plastic cups to reduce litter and waste; backstage, water coolers are used instead of plastic bottles. The Festival commission wildlife investigations of the site and go to great lengths to protect local waterways, land and the biodiversity of the area from negative impacts of the event.

Over the last five years Cambridge Folk Festival have reduced their diesel usage by a third. These achievements are a testament to what can be achieved when supplier and festival teams bring mutual commitment and prioritise reducing their environmental impact.

Latitude, Leeds & Reading

Festival Republic: Energy Management at Reading, Leeds and Latitude Festivals.

Festival Republic is a leading UK music events producer with a portfolio of 19 music festivals across Europe, including Download, Latitude, V Festival, Reading, Leeds and Electric Picnic Festivals. More than half a million people attend the festivals they own and co-produce each year.

Festival Republic are committed to understanding and reducing the environmental impact of their festivals but this case study focuses on the challenges and successes of their commitment to reducing CO2 emissions from energy use at Leeds, Reading and Latitude.

Their sustainability policy includes using waste vegetable oil biodiesel to power the festivals’ generators. Between 2010 and 2011 they increased the amount of biodiesel used at Leeds from 18.5% to 24.5%, and at Reading from 12.5% to 18.2% in 2012. This commitment continues despite there being limited biodiesel supply in parts of the country, unpredictable price fluctuations, and a higher cost for sustainable biodiesel in comparison to regular diesel. They now aim for biofuel to make up 15% of the total fuel burned on site, in line with the Julies Bicycle benchmark, and are investigating into fuel efficiency measures to reduce the amount of fuel they use in the first instance.

Festival Republic requires their energy contractor to monitor generators and provide data on the actual fuel consumption after the festival. Based on the data collected, Festival Republic is working to reduce the size and/or number of generators to better match their energy needs and be more efficient about their fuel use. In 2015 Leeds and Latitude Festival were able to reduce the overall size of the generators compared to 2014 and this was achieved even though there was an increase in the festivals infrastructure. 2016 is the fourth year of data they have collected and are working closely with their power suppliers to see if this can be used to make further energy efficiency savings.

In 2015 Festival Republic explored alternative and new energy technologies such as hybrid generators and solar power. They also hired solar powered batteries that can be linked to generators to reduce the generator run-time. After a trial at Latitude, one of the power contractors has invested in a number of these batteries tailored to their technical needs to add to their own fleet, showing that Festival Republic’s dedication is indirectly supporting fuel efficiency in the broader events industry. Combining the two different technologies has been challenging, requiring training for the engineers in the field and dedication from the teams. The initiative is not yet financially viable, but Festival Republic continues to invest to support this kind of knowledge exchange between solar power and generator companies.

Festival Republic works with their contractors to reduce energy demand through specifying more energy efficient technologies; for example, in 2012, Colour Sound Experiment, one of their lighting and visuals rental companies, invested in 1.5 km of LED festoon lighting in response to demand from Reading Festival. The Festival Republic technical production teams work with their audio, video, and sound companies to improve communication around power specs and energy requirements to encourage broader industry conversation about ‘what’s actually needed’ at festivals.

At Latitude in 2015, the audience was engaged around the topic of energy and sustainability through a partnership with De Montfort University’s ‘Face your Elephant’ project. The audience were also physically acquainted with energy awareness through cycle-powered phone charging stations to promote renewable energy in a creative way.

Since 2009, Leeds and Reading festivals have reduced their total carbon emissions significantly, by more than 20% per audience day. In 2015, Latitude and Leeds were awarded a Creative Industry Green rating of four stars and Reading has achieved three stars since 2013. 2016 was the first year in which Download and V Festival were assessed and at the time of writing this case study the results are awaited.

The Green Gathering

Engaging the community in using renewables

The Green Gathering is a festival with an environmental and social justice focus; it has workshops and talks on permaculture, politics, ecology and crafts, as well as art, live music and spoken word performances. It currently has a capacity of 5,000 and takes place in Chepstow, Monmouthshire.

The Green Gathering is proudly run on 100% renewable energy solutions. Throughout the years the organisers have faced and overcome many challenges in producing a festival with no generators. Many of the solutions to problems in this area have come from successfully engaging their community of audience, traders and suppliers in a shared commitment to operating sustainably.

To providing lighting for the festival without using generators they switched to 100% LED lighting throughout, which was a bigger challenge that it sounds due to an initial lack of suppliers of relevant products. Over the years they have engaged suppliers to build up a list of companies who can step in to provide the right products in the right quantities onsite.

Wheelchair and mobility scooter charging using renewable technology was a challenge to overcome as The Green Gathering’s Assisted Access camping area filled up and demand grew. The festival implemented a number of solutions in 2014, ranging from bringing in extra solar power providers to communicating with the audience to inform them to arrive with batteries and spares fully charged, and by stipulating charging times. These measures were so successful that in 2015, The Green Gathering was able to extend its Assisted Access area further with confidence that the audience’s energy needs could be catered for.

“Informing and engaging customers is vital to keeping them on board and positive about running on renewables, especially if being ‘green’ means they can’t have exactly what they want when they want it!”

The Green Gathering requires traders to be 100% renewably powered, ethical and offer a quality product or menu. For traders who meet these criteria but usually run on mains electric, advice and information is on offer to help them go ‘off grid’. In some cases traders can be linked up with the festival’s regular renewable power providers who may, for a small charge (or free meals!) be able to provide the power needed. The festival’s Green Markets coordinator also provides information to cafes about low-energy equipment and menus if they are keen to make the switch to renewables.

“The Green Gathering community has a number of solar and LED experts who can advise traders to help them trade off grid not just for this event but at all events, so that everyone benefits in the longer term. It’s largely about engaging with the traders.”

The people who come together to create and co-ordinate the festival have built up rich resources of knowledge and are keen to share their skills and experience to benefit not only the festival but also the wider world, through empowering people to be environmentally responsible and resilient.

Many thanks to The Green Gathering for providing the information for this case study.

The Pembrokeshire Beach Food Company

Cafe Mor: A revolutionary off-grid catering concession

Pembrokeshire Beachfood has traded at Freshwater West Beach since 2013, a site that is managed by the National Park and the National Trust. Their Cafe Môr trailer offers a range of high quality food inspired by West Wales produce. In March 2015, they won a Sustainable Development Fund (SDF) support from Pembrokeshire National Park Authority to test out an approach that could revolutionise the catering concessions industry and significantly reduce greenhouse gas emissions (GHGs).

Their remote site had no grid connection and, until the start of the project, electrical power was provided by a generator during the day and a hook up at a local farm by night. The SDF support was used to part fund the installation of solar PV panels and a small wind turbine, along with a solar inverter and a battery bank. The system removed the need for a noisy, carbon-fuelled petrol generator by day, and reduced electrical demand at night (with mains electricity used to top up the batteries if required, rather than being the sole source of power at night).

Instant benefits to the business included a reduction in generator noise, less staff time required for generator operation and maintenance, fewer trading days lost due to generator issues and increased power security as a result of having a battery back up. In the longer term the new system will also considerably reduce operation costs: in 2014, Cafe Môr used around 1000 litres of petrol to fuel the generator, which cost around £1,300. Assuming the system is optimised to minimise mains battery charging to almost zero, benefits in terms of reduced petrol consumption, reduced staff time and reduced loss of trading could be in the region of £2,500 per year: the Cafe Môr system cost just £7,500, so this would give a payback time of around 3 years.

Payback times for systems mounted on vans or trailers used regularly at events could be even better. Initial indications based on a system with three days battery life plus wind or solar recharge, during an event of 7-10 days and assuming an electricity hook-up cost of £450+VAT per event, with 10 events per year, would mean the system would pay for itself in less than 2 years on a system costing up to £9000.

Of course this is not just about money — there is significant potential for the industry as a whole to reduce their impact on the environment, and particularly GHGs. 1000 litres of petrol is equivalent to 2.33 tonnes of GHGs per year. Scaled up across the industry of 10,000 units this amounts to a potential saving of 20,000 tonnes CO2e/yr.

The next stage of the project will monitor the electricity generated by the system to establish exactly how much the system generates and therefore how much mains charging is required, and future phases of the project will look at options for reducing the impact of LPG and vehicle fuel.

Bestival

Reducing fossil fuel dependency through efficiencies and biodiesel use

Bestival is one of the last major UK festivals of the summer calendar, attracting over 50,000 audience members to the Isle of Wight in recent years for this creative indie and dance music festival.

From the outset of the festival in 2004, organisers Rob and Josie de Bank were committed to being environmentally responsible and endeavouring to annually increase the use of renewables and WVO generators for energy throughout the festival site.

Since 2013, Bestival has made great progress in reducing fossil fuel dependency and they work closely with their energy suppliers to service their somewhat awkward shaped site with maximum efficiency.

The length of the festival site makes the power supply contract a complex issue and as it is considered, “too big for a single contractor,” they use different suppliers for the arena, the showspace and the campsite.

In 2013 and 2014, Midas Productions UK provided power the campsites and at the Tomorrow’s World zone — an area where the Bestival wanted to focus on promoting a ‘fun, sustainable, inspirational future’. Midas were able to monitor and measure power use over the first year and make changes to improve energy efficiency performance in the following year.

Due to the power efficiencies measures taken and the reduction in diesel generators used on campsites, from 2013 to 2014 overall red diesel use was reduced and biodiesel use significantly increased. In 2013, red diesel measured in at 108,000 litres, which dropped to 97,500 litres in 2014. Biodiesel use increased from 16,500 litres in 2013, to 21,239 litres in 2014.

Bestival have found that the biggest users of fuel are the production sets for the stages and that in order to create the greatest efficiencies in powering them they need to have accurate specifications in order to plan the best generator configurations and timings. This requires committing suppliers to accurate requirements, although their experience is that suppliers are not always keen to “tighten up on spec,” due to the fear of power failure to the stage at times of peak power requirement, possibly because while connection sizes are easier to pin down actual loading is harder to ascertain.

Bestival are learning from such experiences and continue to work closely with their suppliers to measure and record power and diesel use as a key tool in creating future reductions. There focus is on efficient site design and they engage with their audience in green initiatives wherever possible.

Thanks to Bestival and Midas UK for the information in this case study.

Midas Productions

Waste Vegetable Oil is the Golden Touch for Bestival

Founded at the turn of the millennium, Midas Productions has been the power broker for biodiesel, running its generators exclusively on locally sourced waste vegetable oil.

Bestival is a prime example of the company’s capacity to turn a large-scale event on to WVO. Organisers Rob and Josie de Bank have been pushing a green agenda since the festival started in 2004 and Midas moved beyond the campsites to the Tomorrow’s World arena last summer, its second year at the festival, where the focus, aptly, is on a ‘fun, sustainable, inspirational future’.

Crucially, Midas’ continued investment in kit means it can accommodate its ever-busier contract diary, servicing events either side of Bestival and still hitting the tight deadline on the Isle of Wight, by way of example. “We are scrupulous in our priorities as a business, always putting money into generators, mains and distro, so we can continue to deliver in terms of time and quality,” Midas Director, Dave Noble, said.

Bestival Site Manager, Christina Von Bonin, is quick to praise the Midas touch. “It has dispelled the rumours that ‘bio-diesel doesn’t work’ or ‘the generators clog up’ and while the fuel is a bit more expensive than red diesel, we would certainly like to increase the amount we use, in small steps year-on-year,” she said. “It’s easy to work with Midas too, because it’s team is flexible, easy to get on with and straight talking.”

The complexity of the Bestival site means the contract is split between two suppliers, with Midas currently responsible for some 30per cent of the site. But the balance of power is shifting.

Secret Garden Party

The Secret to Saving Money

Secret Garden Party has been running since 2004, but in recent years has been increasing efforts to find alternatives to diesel generators for running this 30,000 capacity independent music and arts festival in Huntingdon.

They’re one of the big names signed up to Energy Revolution, the industry-wide collaboration to tackle climate change through the audience’s contributions to renewable energy, supported by Powerful Thinking. As well as this initiative to reduce festival emissions, they are mixing up the energy supply on site to reduce reliance on fossil fuels. In SGP’s recent 10^th year, Firefly installed part of the festival’s power infrastructure, providing cleaner and greener alternative energy in the form of hybrid, solar and some biodiesel generators.

This consisted, specifically, of:

Cygnus Hybrid Power Generators (5 x 24kVA; 6 x 8kVA; 12 X 1.2kVA – with tower light)
30 x 540W solar fold arrays to form a 16kWp solar system.

These solar arrays powered 12 of Firefly’s Cygnus Tower Lights and fed into a number of the Hybrid Power Generators, storing the power to be used after nighfall.

8 Pyxis Power Packs, 12 Km of LED festoon lighting and over 100 LED floods
15 Biodiesel Generators (3 x 165kVA; 2 x 100kVA; 2 x 60kVA and 8 x 20kVA)

The energy from the this kit provided power for the production village including the site office and event control, crew catering facilities and bar, all campsite power including campsite caterers and security, all campsite lighting, lighting across the whole site and a large proportion of the entertainment fields.

A total of 3,826 hours of diesel generator run time was saved by having hybrid systems – a total of around 50% of total run time. This use of hybrid technology reduced diesel dependency by 10,285 litres. On top of that, this new diverse system saved Secret Garden Party £7,713, and reduced overall carbon emissions for the festival by a staggering 24 tonnes.

The Nationwide Caterers Association

Online Trader Tool Provides Energy Requirements

NCASS (The Nationwide Caterers Association) have launched Connect, a new online hub for administration and due diligence documentation. This will be of great assistance to both Food Safety Authorities checking food suppliers at festivals, as well as festival organisers and event planners predicting how much energy they’ll need to supply for traders.

Connect is a trader database, which contains important documentation and certificates such as training and hygiene certificates. It operates like an online passport into any events, as event organisers can simply vet trader applications through Connect rather than requesting documentation. What is even more revolutionarily, is the inclusion of an energy calculator, so mobile caterers and festival food suppliers can list the kilowatt needs of their appliances and gas requirements.

This will greatly improve festival organisers’ ability to estimate the energy required for their event, and subsequently better predict the capacity of the generators required to supply specific clusters of caterers. This will lead to huge savings, both in terms of money and energy – Powerful Thinking’s 2013 guide, “The Power Behind Festivals”, found that overprovision of generator capacity, and, subsequently, generators being run at low loads is common at festivals, and a big source of energy inefficiency.

Traders can join Connect for free, as can events and festival organisers and enforcement officers. It will be possible to see which traders and are signed up for what festivals. This will also improve efficiency for the Food Standards Agency and enforcement officers who will be able to check in advance which food suppliers they have already checked at earlier festivals.

NCASS will also partake in another sustainability initiative this summer. They’ll be linking up with FareShare and A Greener Festival to work on saving up to 60 tonnnes of food that is otherwise wasted at festivals. Eighth Plate, a food waste distribution project, will collect, redistribute and look at cooking food into meals. This food will be given to charities and food banks to provide free meals for those in need.
