By the year 2030 80 percent of electricity consumption should come from renewable sources, according to the federal government's target. The switch to a renewable electricity system is a crucial forerunner for the macroeconomic transformation to climate neutrality. On behalf of Agora Energiewende, together with Consentec, we examined how the transformation of the German electricity sector can succeed by 2035.
The study authors developed the scenario “Climate-neutral electricity system 2035" (-CN2035). It addresses the question of how the transition of the German electricity system to renewable energies can be achieved by 2035. It analyses the consequences for electricity generation and consumption and examines the effects on network expansion and operation. It builds on the study “Climate-neutral Germany 2045” (KNDE2045), in which a macroeconomic transformation scenario for climate neutrality was modelled. CN2035 continues to develop KNDE2045 by updating the existing model to meet new government targets for renewable power generation and electricity consumption. Prognos has already created the electricity market modelling for KNDE2045 and has now calculated an updated electricity market model. Based on this, Consentec GmbH created a supplementary network analysis.
“Our new analysis shows a viable path to achieving 80 percent renewable energies in gross electricity consumption by 2030,” explains project manager Marco Wünsch. In addition, it shows that the consistent continuation of the path to 80 percent renewable electricity in 2030 will lead to a climate-neutral electricity system in 2035. At the same time, the coal phase-out until 2030 will occur by means of market instruments and is possible because of the consistent and accelerated expansion of renewable energies; the residual load will be covered by gas-fired power plants. The rapid conversion to hydrogen or hydrogen derivatives reduces fossil gas consumption and greenhouse gas emissions.
At the same time, the analysis highlights the scale of the challenge: The yearly addition of wind and solar power plants will increase from 7 gigawatts in 2021 to 29 gigawatts in 2025, reaching a peak of 39 gigawatts in 2030.

Prognos compared international industrial electricity prices for the Austrian electricity industry. Based on this analysis, we also developed recommendations for government instruments to reduce electricity costs.
Grid operator TenneT has put an important power line into operation in Lower Saxony. Prognos supported the communication for the project.
Primary energy consumption in Germany has fallen by a total of ten percent in the last two years. However, not all sectors have been successful.
How can EU member states accelerate the expansion of renewable energies? Our report for the European Commission analyses which measures are needed to simplify approval procedures.
Prognos will support the Federal Ministry of Economics in preparing the NECP progress reports until 2027.
How can Germany as an industry location achieve net zero by 2045, whilst still maintaining its competitiveness? This study updates our 2021 calculations made on behalf of Agora Think Tanks.
Prognos supports transmission and distribution system operators in the planning and construction communication of the various power line construction projects at the extra-high and high-voltage level.
Electricity prices are closely linked to the development of gas prices. Using three supply scenarios for natural gas we developed forecasts for the development of electricity prices up to the year 2045.
Using a target scenario, we investigated how Thuringia can achieve its climate goals on behalf of the Thuringian Energy Ministry.
For the Council of Experts on Climate Change we conducted an expert appraisal to review the Federal Environment Agency’s greenhouse gas projection data.
