004 - Price Spikes vs RE Power percentage

There's been plenty of coverage of electricity prices and regional electricity issues - I thought I'd draw up the number of price spikes where trading interval (half-hour average price) was above $5,000 per megawatt hour over the past decade (ish), and compare it to the (still relatively small) penetration of non-hydro renewable (solar, wind) in the National Electricity Market.
