Overview
- Finanztip calculates that consistently charging an electric car in low‑price windows can save about €300 per year, with rare negative wholesale prices offering occasional extra gains.
- Quarter‑hourly settlement is expected from October 1, which could sharpen price signals beyond today’s hourly variation for households able to fine‑tune consumption.
- Since 2025, suppliers must offer at least one dynamic tariff to customers with smart meters, and roughly 928,000 households are projected to have them by the end of 2025.
- Consumer groups recommend these tariffs primarily for households with shiftable loads such as EVs, heat pumps or batteries, and Finanztip highlights four options: Ostrom SimplyDynamic, Volkswagen Naturstrom Flex, naturstrom smartdynamic and Octopus Energy’s dynamicOctopus.
- Cost frictions persist despite a legal cap of €100 plus about €30 yearly for voluntary installation by basic operators, with reports of far higher charges including Eon’s average €547 and some cases approaching €1,000.
