Standby power for a major Australian power station

Client: Major French multinational utility company

Location: Victoria, Australia

Sectors: Utilities

The Challenge

Providing 6MW standby power to a remote power station

Set in Victoria’s Latrobe Valley, 150km east of Melbourne, coal-fired Hazelwood power station was slated for closure in March 2017. Until then it was critical to keep it running, since Hazelwood was responsible for over 5% of Australia’s energy demands. The local Victoria region alone depended on it for up to a quarter of its energy needs. However, due to the plant’s age, three of its four main transformers failed in mid-2016. Hazelwood needed to install 6MW of standby temporary power while these transformers were repaired.

The challenge was finding someone able to provide such a substantial amount of temporary power securely to such a remote area and unique site to the required deadlines. Hazelwood also had to allow for the possibility that maintenance works might take longer than expected, as it was hard to predict the scale and complexity of the repairs.     

Project Fact File

Temporary power required 6MW
Power station total output 12,000GWh
Supplying 1250 kVA each 6 Generators
"Aggreko understood Hazelwood’s needs, anticipated any technical issues and delivered a robust solution on time and within budget that exceeded expectations."



The Solution

Flexible power, solid reliability

Hazelwood chose Aggreko to provide the 6MW temporary standby power required while they removed, repaired and re-commissioned three of the four main transformers on site. We provided six 1250kVA generators, a 6-pack transformer, bulk fuel tank, NER, cable sets, fuel delivery system, cable tray and ladder. Aggreko ensured Hazelwood had everything they needed to offer the power back-up required and oversaw the entire project from start to finish. The initial hire request was for one month but it proved no problem to extend this to three when maintenance works overran.       

The Impact

Back-up power delivered on time, on budget

Part of the Aggreko approach is a dedicated team to help design and deliver the best solution for you and respond to any changes – illustrated perfectly by the need to extend the hire period by a further two months. Our team saw that this was done seamlessly. The entire project was a success.
