DBP Development Group

A dispute between privately owned Alinta Energy and Horizon Power hangs over state government plans to overhaul the north-west's unregulated electricity network.

Engineering and construction contractor Monadelphous has won a $150 million contract extension for maintenance works at Chevron's Gorgon liquefied natural gas project, as well as construction work linked to the oil and gas giant's Wheatstone project and new work in Queensland.

An array of large and small projects will push WA's petroleum production to 1 million barrels of oil equivalent per day for the first time next year.

Duet Group subsidiary DBP Development Group has been selected to build infrastructure to link Chevron's Wheatstone gas project to the Dampier to Bunbury pipeline for domestic use.
