Yes, gas and many renewable generators don’t make any money at the current average wholesale price. They make most of the money when the spot price peaks due to high/peak demand periods such as very hot days or when a generator is unable to supply to the network.
Some gas generators in the past have also sat idle until such time where spot prices peak, as they can make more money in the few hours from time to time than running 24/7.
The US appears to have a contestable energy market place. Contestable energy market also exists in Australia and many moderate to large users are within the contestable market.
Whether it is beneficial for small and domestic consumers is questionable as these users often use more electricity when spot prices are higher, and less when spot prices are lower. This means that these users on average pay significantly more than the average spot price for power. If a user generally follows the demand profile on the network or uses mostly when spot price is low, there can be significant savings to the consumer over regulated tariff pricing.
