Dublin, 31st August 2021, Fast growing pan-European Independent Power Producer
("IPP") Alternus Energy Group Plc (OSE: ALT) (the "Company" or "Alternus")
continues its expansion and doubles its installed capacity with the acquisition
of a 64.6 MWp Polish solar park from leading global renewable energy company
BayWa r.e. The sales contract was signed between the parties in August 2021.

The solar park is in Witnica, close to the German border between Poznan and
Berlin. It is Poland's first subsidy-free utility-scale solar installation with
a corporate power purchase agreement (PPA) in place. The project is also the
largest in Alternus' operational portfolio to date. BayWa r.e. will continue to
supply operations and maintenance services at the solar park.

A 10-year virtual PPA has been secured with Górazdze Cement S.A., the Polish
subsidiary of Heidelberg Cement Group. 

Speaking about the exciting acquisition, Vincent Browne, Chairman and CEO of
Alternus said:

"We are delighted to mark our official entry into the Polish market with the
acquisition of the Witnica solar park, the first subsidy-free, PPA-backed
utility-scale solar installation in Poland. We have plans for further expansion
within the country over the next 12 months and hope to share updates on that
shortly. It was a pleasure working with the BayWa r.e. team on this project and
we look forward to future successful engagement with them across key markets." 

Commenting on the new partnership, Dr. Benedikt Ortmann, Global Director of
Solar Projects at BayWa r.e. said: 

"The sale to Alternus Energy aligns well with our goal of developing and selling
additional solar capacity in Poland in future years and further highlights the
attractiveness of renewable energy assets to investors. We look forward to
future engagement with the Alternus team as both companies work to support the
transition to renewables across Europe."

"With this acquisition, Alternus increases its power generation capacity by 100%
and now operates a diverse portfolio of 24 solar PV parks across five European
countries with a combined capacity of 130 MWp" added CFO of Alternus, Joseph
Duey.
