General Electric Company (NYSE:GE) is exploring a sale of its steam-power unit, according to people familiar with the matter, as Chief Executive Officer Larry Culp looks to raise cash and revive the ailing energy business. The company plans to gauge buyer interest in the steam operations in the coming months, said the people, who asked to not be identified because the matter isn’t public. No final decision has been made, and GE could decide to retain the asset, the people said.
