June 10 (Reuters) - Ireland's DCC said on Wednesday it would support a sweetened £5.7 billion ($7.63 billion) takeover bid by a consortium of KKR and Energy Capital Partners if the U.S. private equity firms formalise their offer.

The revised proposal comprises £65.25 in cash and DCC's proposed final dividend of 147.22 pence per share.

Here are more details:

o Shares in the Dublin-based energy distributor rose 3.3% to 62 pounds apiece after the new proposal.

o The revised bid is 12.5% higher than the £58-per-share cash proposal DCC rejected in April.

o The deadline for the consortium to make a firm offer has been extended to July 8 from June 10.

o The latest proposal is a 24% premium to DCC's April 28 closing price, a day before it said it was reviewing the consortium's first bid.

o Earlier on Wednesday, Sky News reported that the consortium was in detailed talks to acquire DCC at a value of more than £5 billion.
