The builder of Australia's first waste-to-energy plant, to be officially opened today in Kwinana after more than six years of work, has revealed it cost about $1.1 billion.
Spanish construction group Acciona is keeping its options open after quietly withdrawing its application to the ACCC to buy a giant waste-to-energy plant at East Rockingham.
Acciona is tightening its grasp on the state's long-delayed and cost-overrun waste-to-energy sector, as the competition watchdog investigates its proposed deal to buy the only other plant in WA.
Spanish engineering giant Acciona has dumped French multinational Veolia from a contract to run WA's largest and most expensive waste management facility at Kwinana.
Government infrastructure could be built faster and to a higher standard if construction firms were engaged early in the planning process, according to the boss of Acciona Australia.
