SAO PAULO, Jan 18 (Reuters) - Brazilian power company Energisa is working to launch a primary share offering aimed at raising around 2 billion reais ($404.24 million), it said on Thursday.

The company said it expects the offering would be launched after the market close on Friday.

Energisa tapped Itau BBA, Bank of America Merrill Lynch Banco Multiplo, Bradesco BBI, BTG Pactual, Citigroup Brasil, J.P. Morgan and Scotiabank Brasil to coordinate the offer.

The issue is still subject to corporate approvals and market conditions, Energisa said, adding that its controller shareholder, Gipar, intends to join the offering.
