Coal to the Rescue in Chile
Chile is a country with a heavy reliance on hydropower and gas
fired combined cycle. However, a crisis in the supply of gas to
Chile forced many of the gas fired plants to swap to expensive
imported oil as replacement fuel. The long term solution for base
load power is the development of coal fired power stations and more
GHD’s Santiago office is playing a major role in the
development of new power projects in Chile and nearby Peru with
significant roles in environmental permitting and project
development. One of these roles is Owner’s Engineer to Colbun for
the development of a 350MW coal fired power station.
Cogeneration plants increase energy
Two new 140MW gas-fired cogeneration units in Western Australia
were the latest projects delivered through GHD’s long relationship
with leading energy infrastructure company Alinta.
The cogeneration plants deliver more than 75 percent energy
efficiency, compared with 25-50 per cent for other power plants
operating in Western Australia. The recently completed cogeneration
units are located within Alcoa’s Pinjarra Alumina refinery in the
south-west of Western Australia. The combined output of the units
is 280MW of power, and up to 840tph of steam.
