A current analysis of the consulting company “Enervis” shows: The consistent expansion of wind power, photovoltaics and small hydropower demonstrably lowers domestic electricity prices over the entire year, in all hours and months – and at the same time strengthens independence towards gas imports. Without renewables, the annual electricity costs for a household would increase by around 73 ꞓ. For 2030, an additional gas import in the amount of the current total consumption of all east. Households necessary.
The study created by Enervis expert Thomas Rosenzopf shows that the Electricity -price -damping effect of wind and sun occurs all year round and at all times of the day – Noticeably lunch in summer with the peak of the PV, but also in the winter months, then when wind power brings its strongest performance. With the consistent expansion of renewables, import dependence on gas and electricity is reduced from abroad.
In retrospect, the study analyzes electricity market development with and without the production of PV, wind and small hydropower for the years 2021 to 2024 and includes a forecast for 2030. The result: Without wind power, PV and small hydropower Would be the electricity prices an average of 6 percent higher in the past four years been. For 2030, a price increase of around 20 percent is expected without this renewable generation (an increase of 18 euros per MWh). “Especially at times of high gas prices – as last in 2022 – the price -lowering effect of renewables is particularly clear,” said Student author Rosenzopf. “Without renewable, the price rash up would have been clearly higher at the time of the energy crisis.”
Renewable displacements more expensive fossil generation
The price reduction has a clear reason: renewable energies have extremely low variable costs and thus shape the market price. With each additional system, the range of electricity increases and the offer curve moves towards cheaper electricity prices – keyword Merit Order. Fossil power plants – especially imported gas – are increasingly displaced from the market. Without renewable Would that be Gasimportbedarf in the year 2030 by 1.8 billion m³ higher. That would Grickey today’s total consumption of all Austrian households (2 billion m³). In industrial numbers Three times as much as the annual gas consumption of Voest. (600,000 cubic meters). This additional gas consumption corresponds Also a quarter of the home gas storage facility.
The Managing Director of the small hydropower Paul Ablinger says: “The study shows what we have always said: domestic production is a location asset, it used to be the case and applies much more in the future!
Electricity bill for households would be significantly higher in a few years
In addition to security of supply, independence and resilience, the further expansion also brings tangible economic advantages: Without the renewable wind power, PV and small hydropower, a single private household would have had In recent years, additional costs of around 34 euros per year worn. Bis 2030 Would the electricity bill Without this renewable for a budget by 73 euros annually. There was a comparable price plus in 2022 at the time of the energy crisis.
In retrospect, industrial companies with 10 GWH annual consumption had been considered to have 182,000 ꞓ in additional costs.
“The study shows black and white that the most effective method against high electricity costs is the consistent expansion of renewable. PV Austria managing director Vera Immitzer.
“This scenario – cheaper budgetary prices and immense economic benefits – is currently sacrificed by the Federal Government daily because the renewable expansion is more and more hurdles in the way,” warns IG Windkraft Managing Director Florian Maringer.
Economic benefits 2030: 3.1 billion euros
The economic benefits of renewable effects solely due to the price -damping effect in the large -scale market market in 2022 was around 1.4 billion euros. In 2030, PV, wind and small hydropower result from the lower electricity price of up to 1.6 billion euros annually. If you add the lost revenues from exports, you get EUR 3.1 billion in total benefits.
