Activ8 Energies powers up for UK expansion with Low Carbon Energy deal

Ireland’s leading solar panel provider Activ8 Energies, has acquired solar firm Low Carbon Energy (LCE) as it reveals ambitious plans to expand across the UK renewables sector.

The move for the Burnley-based firm comes as Activ8 eyes more UK commercial infrastructure projects following recent work on a £3million solar farm at John Lennon Airport in Liverpool. The new installation, which goes live next month, will provide 25% of the airport’s electricity.

Activ8, which is 50% owned by SSE Airtricity, an Irish subsidiary of SSE, is planning to double turnover and installed solar capacity over the next few years as it sets its sights on expanding beyond Ireland and becoming the biggest commercial and industrial renewable energy provider in the UK.
