The owners of Irish wind energy company Airtricity have put the company up for sale.
Industry sources say the group could fetch more than €2 billion. Earlier this year Airtricity sold its US division for €1.1 billion.
The renewable energy firm sold its US division for €1.1 billion in October, before choosing to undertake a review of its strategic options.
The outcome of that review is that the company will now be put on the market, with Credit Suisse and NCB retained as financial advisors for the planned transaction.
Toll road operator NTR owns 51% of Airtricity. The other shares are owned by renewable energy company Ecofin and Airtricity staff and management.
Airtricity is a world leader in renewable energy development and wind farm operations, and has 14 wind farms throughout Ireland and Scotland.
It currently supplies green energy to over 35,000 commercial customers in Ireland.
