AGL has appointed former chief financial officer Brett Redman as chief executive on a permanent basis.

Mr Redman has been interim CEO since August, when Andy Vesey left following a period in which the energy supplier was criticised by pro-coal groups and politicians including Barnaby Joyce for scheduling the closure of the ageing Liddell power station.

“Having had the opportunity to work with Brett during his four months as interim CEO, the board has been greatly impressed with the manner in which he has led the business,” AGL chairman Graeme Hunt said on Tuesday.

“He has demonstrated an energy and rigour and a commitment to culture and performance that has been welcomed by all.”

Upon succeeding Mr Vesey, Mr Redman said he did not anticipate any change in AGL’s move away from coal and other carbon-intensive energy sources.

Mr Hunt said the board had looked overseas and domestically, assessing both internal and external candidates.

Mr Redman, who will receive a $1.65 million salary before bonuses, has been with AGL since 2007 and became CFO in 2012.

The energy supplier is now looking for a permanent CFO, with Damien Nicks continuing to serve on an interim basis.

AGL shares were down 4.0 cents, or 0.2 per cent, at $19.76 at 1104 AEDT on Tuesday, outperforming both the utilities sector and the overall ASX.
