University of Southern Queensland Facility of Health, Engineering And
University of Southern Queensland Facility of Health, Engineering and Sciences Low Load Frequency Support Capability - Collie Power Station A dissertation submitted by Alan Christian Cornish In fulfillment of the requirements of ENG4111 and 4112 Research Project towards the degree of Bachelor of Power Engineering (Honours) Submitted: October 2020 Abstract Energy markets around the world are in a transitional phase, where wind and solar generation are penetrating the markets at unforeseen rates. The desire to decarbonise emissions associated with power generation in Australia, is seen as the first step in meeting our commitments to the Paris Climate Change Agreement. This has had a significant effect upon the electricity grid within Western Australia. The high volume of renewable generation is creating grid instability during times of low demand. This is a result of fluctuations in generation due to the variability of wind and solar. Network strength is no longer as robust because of the loss of synchronous inertia that was behind a grid mainly powered by thermal machines. Many coal fired stations are attempting to become more flexible and change from base load to cyclical operation to assist counteract the irregular nature of wind and solar generation. Collie Power Station is one such station, attempting to improve its operational flexibility. One aspect is the desire that the station move from a current minimum load setpoint of 130MW to 105MW (generated) to assist the station remain dispatched at low load rather than desynchronising it from the grid. The aim of this dissertation is to model the frequency support capability at 105MW to determine if the station continues to provide frequency support for the grid. -
2014-11-25 QWON Power Stations
LEGISLATIVE COUNCIL C1379 QUESTION WITHOUT NOTICE (Of which some notice has been given) Tuesday, 25 November 2014 Hon Robin Chapple to the Leader ofthe House representing the Minister for Energy. Please provide a summary of all active power stations in Western Australia, including: age; capacity profile; fuel and/or mine type; number of employees; whether it is on or off the grid; and the closure schedule. I thankthe Hon. Member for some notice of this question. I table the attached document. The Public Utilities Office has relied on the Independent Market Operator for data concerning generators on the SWIS and has reported the maximum sent out capacity offered by these facilities into the Balancing Market, as of 25 November 2014. These figures may differ slightly from the number of capacity credits awarded and from facility nameplate capacity owing to factors including parasitic load and ambient temperature. For NWIS and NIS facilities, various sources have been used as there is no single definitive list of facilities. The nature of mining operations has not been investigated. The Public Utilities Office does not have access to data on the number of employees or on the closure schedule of power stations. The expected plant life of power stations is variable, a function of maintenance regimes and commercial considerations. ATTACHMENT TO QWN C1379 . 'I .

Extract from Hansard [COUNCIL — Tuesday, 15 September 2015] p6252b-6253a Hon Robin Chapple; Hon Peter Collier ENERGY — POWER PURCHASE AGREEMENTS 3306. Hon Robin Chapple to the Leader of the House representing the Minister for Energy: (1) Will the Minister provide a list of all of the Power Purchase Agreements signed in the last ten years, detailing which companies were contracted, for what capacity, which fuel was to be used in the electricity generation and what proportion overall is from renewable sources? (2) Will the Minister provide a list of all the coal fired power stations, including the various stages of those plants, in the South West interconnected system and the year that they were built? (3) Will the Minister outline the life expectancy of a coal fired power station? (4) For the coal fired power stations owned by Synergy, will the Minister outline the availability of these plants over the last five years taking into account all downtime due to planned and unplanned maintenance? (5) For the coal fired power stations owned by Synergy, will the Minister outline the expected timeline for the closure of those power stations, given that many of them have exceeded their initial life expectancy? (6) How much has Synergy spent on maintenance, including all refurbishments and upgrades on its coal fired power stations over the last five years? Hon Peter Collier replied: (1) No, this information is commercial in confidence. (2) The table below details all of the coal fired power station units currently operational in the South West Interconnected
