Homeowners in Japan and Germany show strong interest in innovative electricity tariffs

A Statista survey for E.ON in Japan found that 60 % of owners of homes equipped with electric cars, heat pumps or solar panels are willing to switch to new electricity tariffs, with 66 % of electric‑car owners open to either dynamic rates or fixed‑price plans with flexible add‑ons. The survey highlighted that dynamic tariffs follow 15‑minute market price changes, while fixed‑price tariffs keep the per‑kilowatt‑hour price steady and include a bonus that reduces the bill. E.ON Germany’s customer‑business head Martin Endress said customers prefer secure rates and that both tariff types can help charge EVs, run heat pumps or store battery energy when demand and prices are low.

In Germany, the price‑comparison portal Verivox reported that 81 % of electricity contracts concluded through its platform in the current year were for 100 % renewable‑energy tariffs – the highest share recorded. The shift is driven not only by environmental concerns but also by cost savings, with the cheapest green tariffs averaging €0.219 /kWh compared with the overall household average of €0.312 /kWh. A three‑person household using 4 000 kWh annually could save roughly €400 per year by switching. Verivox energy expert Thorsten Storck noted that green tariffs often now represent the most affordable option for consumers.
