It is a transformational time for the telecommunication sector, and currently, thousands of new sites and structures are built every month across multiple countries in preparation of 5G rollouts, 4G expansions and in compliance with agendas for sustainable site structuring and re-structuring designed to reach targeted reductions in CO2 and particle emissions, reduced noise, and decreased vibrations. On December 6-10, 2021, tower industry leaders from across the continent will come together, alongside a senior group of handpicked mobile network operators (“MNOs”), investors, solution providers and other key stakeholders for the 8th Annual TowerXchange Meetup Asia. Advent, turnkey supplier of power generators for the green agenda, will be joining the event.

During the event on December 6-10, 2021, Advent will be represented via a virtual booth by its team members looking forward to discussing how fuel cells can support MNOs in their green transition phases.

On December, 8, 2021, Mr. Kim Abildgaard, Business Development Director from Advent, has been invited to speak on the exclusive session: “TowerXchange Dragon’s Den.” TowerXchange’s Dragon’s Den is a unique opportunity to see how C-level executives from leading towercos appraise and evaluate how technology can impact their business, as well as an opportunity to hear from the most innovative solution providers working with towercos in Asia. In this session, Mr. Abildgaard will give insights into Advent fuel cells as turnkey solutions to MNO’s, and demonstrate experiences via cases implemented in Asia with leading telcos – what drives customers and the benefits within reach by implementing fuel cell solutions. A replay of the presentation will be available following the event.

Advent will also partake in the December 9, 2021 round-table discussion on: “Fuel Flexibility: creating a roadmap from diesel to renewables.”

Morten Hougaard Sørensen, Advent’s Senior Vice President, commented, “TowerXchange makes great efforts to both set an agenda and pave the way for new and best practice for towercos and MNO’s. In recent years, we have seen TowerXchange opening up its doors to include the green agenda. This focus is highly compatible to our value propositions, offering clean power solutions to replace diesel gensets for towercos and operators. We feel very much at home and are happy to support and participate in the TowerXchange Meetup events.”
