Australian Chart of the week | You’ll have to share your cake: wind v gas in ‘epeak’ battle

Spot prices are back in the headlines with increased renewable generation impacting both long term price trends as well as driving intraday value shifts; especially across mainland regions. With significant renewable generation still to come to replace exiting coal as covered in Issue 39, the key question then becomes: how much value is there in the merchant market (excluding coal) and how are other technologies faring?

In this Chart of the Week, we look at spot revenues in Victoria for coal replacement technologies, and the impact the transition is having on captured value for these technologies. A clear trend in intraday value shift is now evident mainly driven by increased solar; both rooftop (reduced grid demand during the day) and grid-scale (coincident increased supply during the day).

The key question then becomes: how much value is there in the merchant market (excluding coal) and how are other technologies faring?
