Nov 2 (Reuters) - Australia's Origin Energy said on Thursday it had received a sweetened takeover bid from a Brookfield consortium, valuing the power producer at A$16.40 billion ($10.49 billion), days after its top shareholder rejected the previous offer.

The consortium led by Canada's Brookfield is now offering Origin shareholders A$9.53 per share, up 8.2% from the prior offer of A$8.81 apiece, and a 5.1% premium to its last close.

"The Origin board unanimously recommends that shareholders vote in favour of this revised Scheme at the scheme meeting, in the absence of a superior proposal," the power producer said in a statement.
