Queensland Minister for Energy, Renewables and Hydrogen, Mick de BrenniĀ is welcoming the return of unit B1 at Callide Power Station earlier today.

Following an effort involving more than 300 employees and contractors, unit B1 was turned back on and is now flowing reliable and firmed energy into the grid.

The explosion of one of its turbines cut electricity to over 400,000 Queenslanders late last month.
