The first of three ABB transformers arrives at Barker Inlet Power Station
As Australia’s energy mix grows to include more and more renewable energy, peaking power plants like Barker Inlet Power Station are becoming increasingly important. Peaking power sources can be activated at a moment’s notice to support energy supply, and the electricity grid, during times of high demand.
“The power station is on track for completion later in 2019 – bolstered this week by the arrival of a massive transformer to step up the generator voltage from 15,000V to the network voltage of 275,000V.”
The transformer is one of three to be installed at Barker Inlet Power Station, and delivering them was no mean feat. Each weighs 100t as is, with additional components to be installed on site to integrate them into the station.
They are being manufactured in Finland by Finnish company ABB; the first was shipped around the globe to Port Adelaide, where it was loaded onto a specialised transporter and brought to the site. They are being installed surrounded by giant blast walls, just in case the unthinkable happens and the transformers fail and catch fire. It is extremely unlikely that such an event would ever happen – but safety is paramount at the site.

How will the plant work?
The Barker Inlet Power Station will have around 210 MW of capacity which involves the installation of 12 reciprocating engines that can generate approximately 18 MW each from either gas and or liquid fuel. The units are capable of operating at full capacity within five minutes of starting, providing a rapid response to changes in renewable generation supply and demand.
This modern power plant will make a significant contribution to improving energy security in SA. It’s new technology, so it’s much more reliable than the ageing plant it will replace. The equipment is also much more efficient, requiring 28% less fuel (therefore 28% less CO2).
“The Barker Inlet Power Station demonstrates our support for an orderly transition to a carbon-constrained future. The new investment will help phase out the existing turbines with efficient technology that will produce less greenhouse gas per unit of electricity generated.”
