To get the real value to us of electricity, consider the price that people will give it up. “Demand Response” is the nice euphemism for a voluntary blackout.
If I read this graph correctly, look how fast the prices rise, and how small the response is. For example, in South Australia there is only about 10MW available at less than $300/MWh? (From this AEMO report). For reference the total SA demand is around 1500MW. So 10MW is less than 1%.
Consider how few people are willing to turn the electricity off:
AEMO expects there to be approximately 50 MW of demand response in NSW when the price reaches $1,000/MWh.
The total size of the NSW state market is about 10,000MW. Retail electricity sells for $250 — $470MWh (and only $100/MWh in the US). Hence when the price hits two to four times the normal retail cost of electricity, only about 5% of the market say they will willingly stop using it. When the price hits $7500MWh another 2% will give it up. We can’t take this reasoning too far, but the message is clear that the pain of giving up electricity costs […]
