The German electricity market as well as the entire energy landscape currently resembles a roller coaster ride. Whether the record volatility will affect the Electricity prices 2026 remains to be seen how this will continue to affect industry and commerce. With the ongoing expansion of renewable energies, not only are the installed capacities of photovoltaics and wind power continuing to increase, but so are the fluctuations in electricity generation – and thus the volatility of wholesale electricity prices. High and very low price levels are occurring with increasing frequency, while the average price level is also rising. The analyses for the year 2025 from Natural power and the Fraunhofer Institute for Solar Energy Systems as well as the federal government's budget planning for 2026 paint a clear picture: The future belongs to flexible consumers.
Solar and wind dominate the grid
The year 2025 marks a turning point in German electricity generation. For the first time, renewable energies have Lignite overtakes and, with 56 % units, have become the primary power source. With a massive Enlargement of over 16 Gigawatts last year, solar power plants supplied around 87 terawatt-hours Electricity. This development is clearly reflected in the price trends on the electricity exchange. A new record was set in 2025 with 574 hours negative electricity prices recorded.
At the same time, the number of High-priced hours significantly increased in 2025, in which the stock exchange electricity price is partly well over 200 euros per megawatt-hour. This represents a 25% increase compared to 2024. The average price on the electricity exchange also rose by approximately 10,5 % to the previous year to just under 89 euros per megawatt-hour more expensive. Overall, the market is thus sending increasingly strong price signals.
The Price volatility This is a direct consequence of the successful expansion of renewable energies. It also shows that the transformation of the power system is not yet complete. While generation is increasingly dependent on the weather, consumption, grids, and storage have so far only reacted to these fluctuations to a limited extent. The necessary expansion of flexibility options – for example, through Large-scale battery storage, controllable loads, dynamic tariffs and digital measurement and control technology – is lagging behind the expansion of generation.
Bottleneck in BESS grid commitments and lack of flexibility will increase electricity prices in 2026
The storage market is developing extremely dynamically, and the German Solar Industry Association reports that battery storage capacity in Germany has increased fivefold since 2020. Alone 9,710 Inquiries for grid connections of battery storage systems at medium voltage level, there were received by German grid operators in 2025 and only about 3.800 received Commitments.
Meanwhile, applications are piling up, and the TSOs and DSOs are significantly behind in processing them. As a result, the installed storage capacity is well below the level required for a predominantly renewable electricity system. Also, the ones already approved by the TSOs for 2026 and 2027 51 Gigawatts on large-scale battery storage do not create direct effects here. Although short-term flexibility is increasingly available, systemic influence on price stability, grid operation, and reserve power plants has therefore only been limitedly realized so far.
State billions as a price buffer for electricity prices in 2026
Against these backgrounds, politics is increasingly reacting with price support measures. For 2026, the federal government plans to approximately 29.5 billion to spend euros to cushion the electricity prices for companies and households. The funds are used for subsidies for transmission grid fees, among other things, for Reduction of electricity tax, in the Industrial electricity price as well as into the EEG financing about the Climate and Transformation Fund. These measures are supplemented by the Electricity price compensation for energy-intensive companies.
These electricity price relief measures will help limit costs for consumers and industry in the short term in 2026. At the same time, however, critical voices are growing, pointing to the limited sustainability point to this approach. The high state subsidies do not address the causes of the rising system costs, but rather covering price signals, which are actually intended to incentivize investments in flexibility, efficiency, and system serviceability. Individual politicians, expert commissions, and economic research institutes therefore emphasize that measures to reduce overall system costs are more effective in the long term than permanent subsidies.
Why flexibility is twice as rewarding now
Current market data clearly shows that the focus in the power system needs to shift: away from a pure generation logic towards an integrated system approach. An electricity market with a high proportion of fluctuating renewable energies absolutely requires flexible consumers, large-scale battery storage, and intelligent grids that consistently make use of time-variable price signals.
This is exactly where the economic potential lies for companies looking to lower their electricity prices in 2026:
- Leveraging arbitrage effects: Despite delays in grid connection commitments for BESS, the market shows that Power trading with arbitrage revenue – that is, buying electricity during negative price phases and using or feeding it in during high price phases – is a highly attractive business model.
- Load management as a competitive advantage: Companies that can make their processes more flexible through digital control technology and their own storage solutions can escape the rising average price level. They take advantage of the „free hours“ of renewables and bypass the expensive peaks caused by a lack of system flexibility.
- Avoiding network costs Through intelligent self-consumption optimization and Peak Shaving this not only significantly reduces procurement costs but also grid fees – a factor that is becoming increasingly important given the rising system costs in 2026.
Conclusion: Electricity prices in 2026 as a wake-up call for companies
Electricity prices in 2026 will be artificially stabilized by massive government intervention, but record volatility on the stock exchange remains a persistent structural feature. While billions in federal subsidies will alleviate cost pressure in the short term, they cannot replace the necessary technological transformation.
The „bottleneck“ in grid commitments and insufficient flexibility on the demand side are further driving up system costs. The central challenge – and at the same time the greatest opportunity – lies in making this volatility economically usable. Those who invest in storage, digital control, and dynamic concepts now will become independent of government aid programs and position themselves as system-relevant and cost-effective players in a volatile market environment. Volatility is not a risk to be sat out, but a price signal that demands entrepreneurial responses.
