The parliament of the German state of Baden-Württemberg has passed a law amendment on October 6 local time, requiring all new buildings within the state to install photovoltaic solar systems on the roofs starting from May 1 next year.

From January 1, 2023, all existing buildings within the state are also required to retrofit their roofs with photovoltaic solar systems. This measure aims to achieve the state's carbon neutrality goal by 2030. Baden-Württemberg is the third-largest state in Germany in terms of area and population, with its capital Stuttgart being the headquarters of well-known companies such as Daimler.

Due to the increase in spot prices, the German Federal Network Agency, Bundesnetzagentur, has reduced the renewable energy tax, also known as the EEG tax, that consumers will pay for electricity consumption in 2022, to a ten-year low of 0.0372 euros per kilowatt-hour.

This reduction is not surprising, as the continuous rise in spot prices for electricity has reduced the demand for subsidies for renewable energy. This price reduction is also aimed at partially mitigating the impact of price increases.

According to operators, Germany's renewable energy installed capacity in 2022 will reach 8.2 gigawatts, primarily driven by solar energy, and green power generation is expected to increase by nearly 5% to 239 terawatt-hours.
