Ireland’s ESB has selected Spanish power company Endesa as the preferred bidder in the EUR450 million sale of two power stations.

The two companies will now enter negotiations over the finer details of the deal, which they believe will be concluded by the end of the year.

Endesa is reported to have been selected from a shortlist of companies, including AES, Viridian, private equity fund Star Capital Partners and a joint venture between International Power and Bord Gais. ESB is required to divest the assets – two peaking power plants – as part of a regulatory ruling.
