Munmorah Power Station

Munmorah Power Stationis a demolishedcoal-firedpower stationwith four 350MWEnglish Electricsteamdriven turbo-alternatorsfor a combined capacity of 1,400 MW. The station was located nearDoyalson,on the shores ofLake Munmorah,New South Wales,Australiaand was owned and operated byDelta Electricity,acompany ownedby theNew South Wales Government.

In July 2012 the coal-fired generators were permanently retired from service, with demolition occurring from 2016 to 2018. However, the nearby gas-firedColongra power station,which was commissioned in 2009, remains in operation.

History and facilities

edit

The station was constructed with 4 English Electric 350 MW turbo-alternators. Munmorah had a total capacity of 1,400 MW. Steam was supplied at a pressure of 2,500 psi and a temperature of 460 °C. One unit was completed in 1967, another in 1968, and the remaining two in 1969. Units 3 and 4 had fabric filters fitted in the 1980s, and this reduced load to 320 MW each. Units 1 and 2 were relegated to emergency use from 1992.

Munmorah drew salt water from Lake Munmorah, part of theTuggerah Lakes,for condenser cooling. The coal for Munmorah came from two underground mines, Munmorah State mine and Newvale No.2 Colliery, and also from Vales Point coal storage via a series ofconveyor belts.

In September 2007, the New South Wales State Government announced the commencement of a trial of 'clean coal' technology at Munmorah Power Station. The A$5 million trial by theCSIROand Delta Electricity was part of a larger A$150 million trial jointly funded by the coal companies.[1]

On 15 November 2007, 15Greenpeaceactivistsentered the power station property and switched off one of the conveyor belts as a protest against theclimate changepolicies of theLiberal Party of AustraliaandAustralian Labor Partyin the run up to the2007 federal election.[2]

In 2012Carbon Monitoring for Actionestimated the power station emitted 4.246 million tonnes ofgreenhouse gasesas a result of burning coal.[3]

Closure

edit

Delta Electricity announced on 3 July 2012 the closure of Munmorah power station after 45 years of operation due to decreasing energy demand. Parts of the boilers and turbines needed to be replaced which would have cost about $AUD 400 million. Units 3 and 4 had been maintained on standby but had not been in production since August 2010. Munmorah was disconnected from the grid in May 2014 and completely de-commissioned. Plans were made to demolish the station and its out-buildings and sell off the 500 acres of surrounding land for housing and sporting venues.

Chimney Stacks

edit
  • 2 Emission Stacks at a height of 155 metres tall.

Demolition

edit

In 2013 was the beginning for demolition to begin on Munmorah Power Station facilities, the first move was to pull away parts from the boilers. That included some facilities inside the boilers and the vents that went to the emission stacks from the boiler facility. In 2015, was time to disconnect all vintage equipment from the large shed and boiler and send them off to the scrap heap. In December 2015 a survey of the power station precinct found that pollutants(diesel) had entered the water table and made some areas unsuitable for housing.

Demolition started in 2016 and was completed by the end of 2018.

On 26 March 2017 at 10:10am, the two Emission Stacks at 155 metres tall, came crashing down by a controlled demolition.[4]Demolition of the boilers occurred in May 2017 and 2018.

edit

A documentary was based on Munmorah Power Station in the mid 1990s, detailing effects to our environment from coal fired power stations like Munmorah.
