Prices are not high due to renewables. You'll have to show that this is the case to make that argument. AFAIK it's a combination of massively overbuilding the networks (due to privatisation and crappy/most likely corrupt energy regulator allowing companies to decide to overbuild while taking huge profits) plus a whole heap of coal and gas stations being quite decrepit and nearing end of life, with associated high costs of maintenance. Renewable energy isn't really in the picture. To add to this, a massive battery array was installed in South Australia in conjunction with Tesla which helped even out power distribution capacity in the event of drops in power output caused by coal/gas plants struggling during heatwaves, which otherwise would have caused blackouts.
