British utility Centrica PLC has selected Goldman Sachs to help it sell its 69% controlling stake in Spirit Energy Ltd., Bloomberg News reported, citing people familiar with the matter.

It also tapped accounting firm KPMG for audit work on the transaction, which could value the utility's oil and gas exploration and production arm at more than $2 billion, according to the report.

In May, Centrica CEO Iain Conn promised a plan to turnaround the company after a challenging start this 2019. Conn is set to leave Centrica next year.
