Naturgy Energy Group, S.A. (BME:NTGY) has put its Irish commercial gas and electricity supply unit up for sale, five years after acquiring the business, according to industry sources. Naturgy has hired Deloitte in Spain to manage the sale, coming at a time when European wholesale gas prices have spiked to record highs this summer, with a knock-on effect on electricity prices. Sources have confirmed to The Irish Times that the sale relates to Naturgy's Irish energy supply business.

Representatives for Naturgy Energy Group, the Irish unit and Deloitte in Spain declined to comment.
