Dunkelflaute 💥 Heizkosten-EXPLOSION - dynamische Stromtarife? Julian Affeldt | Geladen Podcast

"Those who rely on dynamic electricity pricing can take advantage of dumping prices on the #ElectricityExchange," it says. However, many consumers are still unaware that this statement only applies to the summer. This winter of 2024/25, customers can expect prices exceeding €1.00 per kilowatt-hour in some cases. Our studio guest Julian Affeldt wrote a listener email to the Geladen team after the #Podcast episode with #E3DC CEO Dr. Andreas Piepenbrink: "The idea of ​​operating the home storage system (in winter) according to the exchange electricity price DOESN'T WORK! My heating costs are EXPLODING!" Julian Affeldt criticizes the fact that many providers of #EnergyManagementSystems deceive their customers into believing that they can benefit – even in winter – from the combination of controllable consumers (electric car/wallbox, heat pump, home storage system) and flexible #Electricity tariffs. (Remember: E3DC CEO Piepenbrink had spoken of more than €1,000 per year...). The idea: Through intelligent charging control, a system can purchase electricity at favorable exchange rates and store it until the electricity price rises sharply. After that, the household draws the electricity briefly from the electric car and home storage. In fact, from Julian Affeldt's perspective, these "cheap electricity price windows" in winter are (a) too short and (b) "unfortunately still too expensive" to save real money (compared to fixed-price tariffs). The biggest problem appears to be that the control system has no options left during periods of low electricity demand: "Our energy management system obviously can't simply shut down the heat pump and the electric car for 3 to 4 days," says Affeldt. On average, the electricity customer with a fixed-price tariff pays less in winter than with a flexible electricity price. "Even a larger #battery storage system wouldn't help us much in this matter.

He is referring to the efficiency of battery storage systems, which is approximately 85%-95%. According to Affeldt, these losses would already become significant in the long term when storing and discharging energy. "If 10% to 15% of the food in a pantry always goes to mice, the purchaser has to take this into account! Especially when comparing special electricity offers that are only slightly above the "normal price." "But what is a "normal price" on the stock market?" the podcast editors later joke.
