Adds details and background throughout

July 14 (Reuters) - Irish energy distributor DCC DCC.L is close to accepting a £5.7 billion ($7.64 billion) takeover proposal from a consortium of KKR KKR.N and Energy Capital Partners despite shareholder pushback, Bloomberg News reported on Tuesday, citing people familiar with the matter.

DCC's shares hit a near six-year high earlier in the session, but were trading marginally lower at £63.45 at 1415 GMT.

Here are some more details:

• DCC, which distributes liquid gas, biofuels, and renewable energy to businesses and households, signalled its support for a sweetened £65.25 cash per share proposal in June, after rejecting a previous bid which it deemed too low.

• Two of DCC's largest investors, Aviva Investors and Fidelity International, have previously opposed the deal, saying the buyout firms were undervaluing the company, the report said.

• The consortium is pushing ahead with its existing offer ahead of a Wednesday deadline, the report added, with DCC's board close to a final sign-off on the deal.

• London-listed DCC and KKR declined to comment on the report, while Energy Capital did not immediately respond to a Reuters request.

• Under UK Takeover Panel rules, the consortium has until July 15 to make a firm offer for DCC or walk away.
