Vodafone regards the adoption of technologies such as the self-powered site as essential to meeting its energy-saving ambitions. As well as reducing Vodafone’s energy consumption, self-powered sites remove the need to connect to the electricity grid, overcoming what the operator says can be an insurmountable civil engineering challenge when building new sites in the most rural parts of the UK.

Other potential benefits of the Eco-Towers cited by Vodafone include: the use of locally generated renewable power to reduce the environmental impact of the site; increased renewable contribution by combining wind and solar with battery storage systems on site, which could remove reliance on diesel generators for back-up power; the quiet, bird-friendly turbine could make the Eco-Tower viable for the most sensitive of sites, including areas of outstanding natural beauty; and on-site power generation that is independent from the electricity grid may improve security of supply.

“We are committed to improving rural connectivity, but this comes with some very significant challenges,” said Andrea Dona, chief network officer at Vodafone UK. “Connecting masts to the energy grid can be a major barrier to delivering this objective, so making these sites self-sufficient is a huge step forward for us and for the mobile industry.

“Our approach to managing our network as responsibly as possible is very simple: we put sustainability at the heart of every decision. There is no silver bullet to reducing energy consumption, but each of these steps forward takes us closer to achieving net-zero for our UK operations by 2027.”

Martin Barnes, CEO at Crossflow Energy, added: “We are really excited to be working with Vodafone. It’s a fantastic opportunity to show how our self-powered Eco-Tower solves the problem of harnessing ‘small wind’ to offer not just that all-important carbon reduction, but also significant commercial benefits.

“In the case of Vodafone, it will help to accelerate the expansion of rural connectivity, transform energy consumption patterns and deliver significant economic and carbon savings. Our turbine technology has equally strong applications for so many other industries, but to have such a high-profile player as Vodafone deploying our Eco-Tower is a major endorsement for us and our technology.”
