Danish energy company SE and the PFA pension fund are paying EUR 102 million for 272 wind turbines with a total installed capacity of 196MW across around 80 sites.
According to Windpower Intelligence, the majority of the projects are in the 2-5MW range, with few turbines above 2MW.
The turbines have an average operational track record of 16 years, but the sale includes a 23MW wind farm that is still at an early stage in development.
Dong made clear its intention to sell onshore assets to fund offshore development in a new strategy and financial action plan published in February.
"With the agreement to divest our Danish onshore business, we are taking a further step towards the realisation of that plan," said Dong Energy CEO Henrik Poulsen.
"Our competences and capital will be deployed in offshore wind where we have a strong and differentiated competitive platform."
