Supporting Europe's Clean Energy Future

The European Green Deal provides the policy roadmap to transition Europe to a clean energy economy and sets into motion Europe’s political ambition to be the world’s first climate-neutral continent by 2050. We believe there is no better time than now to invest in the accelerating clean energy transition in Europe.

The mission of Aer Soléir – Irish for “clear air” – is to develop, construct, own, and operate a multi-gigawatt portfolio of onshore wind, solar and energy storage projects that will provide material, long-term economic benefits to local landowners and communities throughout Europe. We strive to supply safe and reliable clean energy to our customers while delivering robust returns for our investors.
