Aug 4 (Reuters) - Oil and gas producer Santos (STO.AX) , opens new tab on Monday said it will supply utility firm Engie (ENGIE.PA) , opens new tab with up to 20 petajoules of natural gas a year from its Narrabri project in New South Wales that has been entirely committed to the Australian domestic market.

Santos has yet to make a final investment decision on the A$3.6 billion ($2.33 billion) project so details including start date and pricing have yet to be agreed.

Earlier this year, Santos received approval from a tribunal to proceed with project, which is expected to ease energy supply constraints on Australia's east coast.

Paris-listed Engie operates wind farms, large-scale batteries and gas-fired power stations, and provides energy services to commercial and industrial customers across Australia.

The supply agreement is subject to Santos making a final investment decision on the project, which it previously said it would make by the end of this year, among other conditions.
