LONDON – September 11, 2018 – Aretex Capital Partners (‘Aretex’), an international private equity firm, announces that it has invested in Building Energy 1 Holdings plc (‘Building Energy’) through its inaugural fund. Building Energy is a global independent power producer of renewable energy.

Building Energy is the third investment for Aretex since its inception in 2018. Aretex has acquired the stake from ZZ Capital, whose investment in Building Energy was sourced and led by Sergio D’Angelo and Andrew Feller while they were partners at ZZ Capital International, respectively leading the European and North American operations.

Building Energy has enjoyed significant growth in the past year, having increased its power production capacity to over 350 MW (operation and under construction). With an established presence in four continents, across four renewable energy technologies (wind, solar, biomass and hydro), and a proven track record of success, Building Energy continues to develop promising projects amounting to more than 1.5 GW, for which the development phase is expected to be completed by the end of next year.

Aretex was keen to continue working closely with the highly experienced management team at Building Energy and sees it as an opportunity to further expand the business in the fast-growing renewable energy industry.
Sergio D’Angelo, co-founder and managing partner of Aretex Capital Partners said: “We have developed a strong relationship with Building Energy over the last year and are pleased to maintain our investment and interest in our new capacity as Aretex Capital Partners and are certain that Building Energy will continue to play a significant role in our portfolio. Supported by our team, the company can continue to make significant progress and further benefit from the global reach that Aretex Capital Partners brings.”

Fabrizio Zago, CEO of Building Energy said: “The renewable energy industry is experiencing rapid growth and with the continued support of the Aretex team, Building Energy is well positioned to leverage new business opportunities and effectively execute our growth strategy.”
