With the way our energy market works, you also don’t want to be on a day ahead tracker in rising market.
Price cap is backwards looking so you want to be catching the tail of lower prices.
Fixed tariffs are forward looking but it’s not day ahead prices, it’s a long term agreement for supply.
Day ahead prices are massively impacted by the weather, and the weather has been awful for renewables for the last 2 months. All the long periods of high pressure in winter mean lots of cloud so solar is well down for the time of year and still air so wind is also well down on typical. On the plus side, it’s been above average temperatures for longer than usual.
