Origin Energy Limited has started construction of the 120MW gas-fired Quarantine power station expansion located on Torrens Island, Adelaide.

It is anticipated that the expansion will be completed in the December quarter of 2008. The expansion will be supplied with natural gas through the SEA Gas Pipeline that connects Adelaide with the southeast Australian gas network, and will be sourced from Origin’s extensive gas supply portfolio.

Andrew Stock, executive general manager of major development projects at Origin, said: The A$80 million power station expansion more than doubles the output of the existing 95MW installation at Quarantine. Many factors, including the addition of significant wind farms in south Australia and an increasing air conditioner load in the state has created the need for more peaking generation capacity.
