The technology could not only support the race to net zero, but also help bring connectivity to ‘not-spots’ in remote and rural areas.

  • Mobile phone mast incorporates a wind turbine, solar panels and on-site battery storage.
  • Initiative raises the prospect of connectivity to cover ‘not-spots’ in remote and rural areas.
  • Supports Vodafone’s target of net zero UK operations by 2027. [1]

Vodafone has switched on the UK’s first live wind- and solar-powered mobile phone mast in Pembrokeshire, Wales. The mast will provide 4G coverage to the community of Eglwyswrw. [2].

The specially designed mast, which potentially removes the need for a connection to the national electricity grid, could provide connectivity to ‘not-spots’ in the UK’s most remote and inaccessible locations – helping the industry achieve 95% of UK landmass coverage by 2025. It will also help Vodafone reduce carbon emissions and support its target of reaching net zero UK operations by 2027.

The ‘self-powering’ mast incorporates a unique Crossflow Energy wind turbine that can generate power even in light winds. The mast can be installed without the need to dig trenches and lay electricity cables, making it faster and easier to install and reducing the impact on the local environment.

It is also extremely quiet, making it viable for sensitive sites such as Areas of Outstanding Natural Beauty. It can also be ‘filtered out’ as a solid object by radar, birds and bats, so it is easily avoided, making it less harmful to wildlife.

The trial, in partnership with wind turbine technology specialists Crossflow Energy and mobile infrastructure partner Cornerstone, is at Home Farm in the village of Eglwyswrw. It will run for two years and data gathered will help Vodafone optimise the technology and determine which sites are most suitable for ‘self-powering’ masts.

Bringing mobile and internet services to rural communities helps boost the local economy, tackle isolation and close the rural digital divide. To date, building masts in coverage ‘not spots’ without an existing electricity connection has been a significant financial and logistical challenge.

Andrea Dona, Chief Network Officer and Development Director, Vodafone, said:

“Connectivity is vital to everyone, no matter where you live. This self-powering mobile phone mast, with on-site battery storage, could help us connect places that were previously impossible to reach. It will also help us reduce carbon emissions and minimise our impact on local environments.
“If this trial is a success, we would like to roll out more ‘self-powering’ masts, with a focus on areas with poor or no coverage.”

Simon Hart, Secretary of State for Wales, said:

“Improving mobile coverage and digital connectivity across Wales is a priority for the UK Government and is hugely important for our economy.
“As we look to create more sustainable growth and jobs, it is fantastic to see green innovation being trialled in our rural communities.”

Martin Barnes, CEO, Crossflow Energy, said:

“We are incredibly excited to be partnering with Vodafone on this UK first. Until now, the use of ‘small wind’ turbines in the race to net zero has been limited due to issues of performance, reliability, and planning concerns, such as noise, vibration, and damage to ecology.
“The unique design of our wind turbine addresses all these challenges head on. We believe that one day its use could be as widespread and commonplace as solar panels.”

Rhys Phillip, Chief Executive Officer, Cornerstone, said:

“As the UK’s leading tower company, we are proud to be involved in this landmark project, driving innovation to create scalable, sustainable connectivity solutions. We look forward to our continued collaboration on our journey towards environmentally friendly site designs.”

Vodafone has committed to reaching net zero UK operations by 2027. Its switch to 100% renewable electricity has already had a significant impact, and it has reduced carbon emissions from its UK operations by 55% on the previous year. It recently signed a 10-year power agreement with three new solar farms in Lincolnshire, Worcestershire and Nottinghamshire, securing their development and bringing additional renewable power provision to the UK grid.

Notes to Editors  

The Home Farm trial

The ‘self-powering’ mast is being trialled at Home Farm, Eglwyswrw, Pembrokeshire, Wales. This is the first live mast of its type in the UK.

To ensure local people stay connected while the ‘self-powering’ mast is being trialled, Vodafone has retrofitted an existing mast site that is connected to the national electricity grid. The mast will be mainly powered by the green energy generated on site but can be ‘topped up’ by electricity from the grid if required. In future, for remote sites with no national grid connection, another power source will be required as back-up. Vodafone is exploring a range of potential options.
