(Adds KPC spokesman, planned BP deal)
KUWAIT, May 11 (Reuters) - Kuwait's state oil group said itsigned a six-year liquefied natural gas (LNG) supply deal withRoyal Dutch Shell on Sunday, worth an estimated $12billion, as the major oil exporter seeks to meet energy demandsfor the hot summer months.
The deal between Kuwait Petroleum Corp (KPC) and Shell wasreported last month in a Kuwaiti newspaper but with no financialdetails.
KPC also plans to sign a $3 billion deal LNG supply dealwith BP on Monday, said Nasser al-Mudaf, head of KPC'sinternational marketing division.
He did not provide the volume of the super-cooled gas thatwould be supplied by the companies. A Shell spokesman said hecould not comment on details of commercial agreements.
Kuwait wants to burn LNG instead of resorting to diesel andcrude oil, which have higher harmful emissions, KPC said in astatement announcing the Shell deal.
Kuwait began importing LNG in 2009 and signed deals withShell and Swiss-based trader Vitol to supply it from April toOctober, the period of peak power demand, for the last fouryears.
Surging air conditioning demand in the scorching MiddleEastern summer and a lack of domestic supply mean Kuwait needsto import more gas each year to feed its power plants.
