Australia’s renewable industry has seen out the roller coaster of ups and downs from 2008 to 2016, but for the past few years has ridden the wave of cheap solar and wind encouraging massive rollouts of large scale projects. It’s pressured older coal power stations to close and created momentum that seems unstoppable.
But then along comes the Duck Curve and looks like becoming the immovable object.
With all the solar generation concentrated in 6-8 hours a day in the Eastern States and much of the wind also concentrated in a few regions so susceptible to similar constraints, pressure on energy prices is now causing investors concern that the guaranteed returns on offer may not be so secure. Even with a PPA, if prices crash and constraints kick in then renewable generators may find themselves shorted on both export ability and income.
While storage is seen as the cure for the Duck Curve disability, it may suffer the same fate, as numerous large-scale rollouts all duplicate each other’s product design and function, primarily FCAS and short term network support at the moment.
The answer obviously lies in flexible alternatives that move us towards a rubust, reliable and less concentrated energy mix.
redT Energy offer utility scale, 25+ year life, zero degradation and unlimited cycling asset based storage solutions. More importantly we also offer to manage the energy to make more money than just using generation alone.
