Fortum Oyj's sale of its Finnish electricity grid has attracted interest from potential buyers including Hong Kong-based Cheung Kong Infrastructure Holdings Ltd., Canada's Borealis Infrastructure, Macquarie Group Ltd.'s European infrastructure unit and Hastings Funds Management Ltd. according to sources.

Borealis, the infrastructure arm of the Ontario Municipal Employees Retirement System, is teaming up with investors including First State Investments and Nordic pension funds, according to sources. Cheung Kong could be working with UBS AG on its potential offer.

The grid may fetch about €2 billion euros and a decision on the winner is expected by December.

Espoo, Finland-based Fortum, the country's largest utility, is weighing sales of its distribution networks in the Nordic region to allow it to focus on generating power. Fortum also plans to sell its larger Swedish grid, which could be worth about €4 billion, next year.

Revenue from Fortum's grids in Sweden, Finland, and Norway totalled €1 billion in the 12 months through September 2012.

Reuters informed in September that Fortum had hired Citigroup and Danske Bank to explore a sale of its electricity distribution business in Sweden and Finland.
