Power generation is 25% higher with 6 than with 12 reactors. Plenty of scaremongering around volatility, though. Consumers don't realize that one-hour price spikes are completely irrelevant since they pay monthly (or even quarterly) AVERAGE prices. Max, min, mean, and standard deviation.

Large customers buy directly on electricity markets at hourly market price, or have direct power purchase agreements with power suppliers.

Most small customers are paying using average prices, but these average prices are calculated from the costs of power suppliers and these are affected by hourly market prices.

Best solution is instalation of smart meters so that small customers pay according to hourly market price.
