Energy2market: Largest provider of negative frequency restoration reserve for small systems
Energy2market (e2m) is the leading provider of decentralized negative Frequency restoration reserve (SRL) in Germany. This is also confirmed by the Bundeskartellamt’s latest report on the balancing market: no other provider has prequalified more decentralized plants for the provision of negative SRL. That’s more than just a title – it’s a real advantage for e2m customers.
What is negative Frequency restoration reserve?
Negative SRL means that systems can reduce their feed-in or increase their load at short notice if the grid requires less electricity. It is a key instrument for keeping the grid frequency stable at 50 Hz and ensuring security of supply in an electricity system with a lot of renewable energy.
Energy2market has fundamentally changed access to the balancing energy market: What was previously reserved for large gas and pumped storage power plants is now also possible for smaller plants thanks to e2m. For the first time, biogas CHP plants, battery storage and flexible industrial process technologies such as ventilation systems can actively participate in the SRL. The decisive factor here is that they must be technically and regulatory pre-qualified.
Largest prequalified portfolio – a competitive advantage
e2m has prequalified more systems for negative SRL than any other provider in Germany. This creates tangible advantages:
Standardized processes for fast market access: e2m ensures a fast, efficient and secure connection through standardized processes, thus creating new economic opportunities for many operators.
More pool power: The more prequalified systems are in the pool, the greater the bundled power that e2m can offer. This enables reliable and flexible provision of control power, even in the event of outages or maintenance of individual systems.
Better bundling of flexibility: Different system types and regions ensure high availability and technical redundancy. This reduces pool costs and increases reliability.
Attractive remuneration for plant operators: A large, technically reliable pool can achieve better revenues on the market because it reliably provides power and can offer it economically efficiently. Larger providers benefit from economies of scale and lower reserve quantities, which has a positive impact on results.
With e2m, small suppliers join forces and operate on an equal footing with the large power plants.
The marketing of negative SRL is a central component in the flexibility strategy of many operators. It opens up new, predictable additional revenues for biogas and CHP plants, battery storage, CHP, industrial processes and even offshore wind farms. e2m is not only present in the market, but is actively shaping it as a particularly successful player.
Our multi-market approach is consistently geared towards the most valuable market product – often with above-average acceptance rates. By regularly calling on our plants, we generate maximum economic added value and at the same time make an active contribution to grid stability. As part of the critical infrastructure, e2m pool power ensures security of supply in Germany on a daily basis.
e2m market leadership leads to particularly attractive conditions:
Maximization of operating hours: Thanks to the large pool, we can react flexibly to price movements and make optimum use of the availability of the plants. Depending on the market situation, we shift the energy volumes between the day-ahead, intraday and balancing energy markets and thus achieve higher remuneration throughout the year.
Lower risk of failure: If an individual system fails, the pool can compensate for this failure. This is because a strong pool not only provides security, but also acts as a unit that is more than the sum of its parts. This means that participation remains reliable and revenues remain stable.
Professional processing: We take care of prequalification, technical connection, timetables and billing – with more than 10 years of experience in prequalification and state-of-the-art IT.
Securing the energy transition together
Control power is becoming increasingly important the more renewable energies are connected to the grid. Decentralized flexibility is a key component in ensuring security of supply, even in a climate-neutral energy system.
As the largest provider of negative SRL for small systems in Germany, e2m not only offers technical expertise and market experience, but also the most economically attractive solution for plant operators who want to market their flexibility in the best possible way.
Those who opt for marketing with e2m benefit from:
Fast, secure and standardized prequalification
a large, stable balancing energy pool
Multimarket optimization
higher revenues
This article is part of a three-part series on the role of decentralized flexibility in the energy transition. Read on to find out why e2m is the first choice for SRL pre-qualification and how flexibility can be marketed profitably.

More revenue despite negative prices: Increasing flexibility for PV systems
e2m launches new product for even more flexibility that automates curtailment in the event of negative prices in a smart way and makes it economically attractive – even for smaller PV systems. For a 2.1 MWp system, this means up to 6 percent additional yield – around €6,000 extra per year.
Powerhouse pilot project in Garrel: battery storage efficiently connected to the grid
HoBohTec GmbH relies on e2m as a partner for the connection and marketing of its first own battery storage system. Thanks to lean processes and close coordination, the modular “Powerhouse” system was quickly integrated into the grid and optimally utilized – a pilot project that serves as a model for other systems.
Solar power without returns - Why storage is crucial now
In this interview, Kurt Kretschmer, Head of Legal & Compliance at e2m, explains why the economic pressure on solar system operators is likely to intensify further – and why flexible solutions such as Storage are the key to remaining profitable even in times of frequently negative electricity prices.
Pioneer in the flexibility marketing of renewable energies
Following the prequalification of the first German offshore wind farm Borkum Riffgrund 1 for the provision of Frequency restoration reserve (aFRR), the wind farm has now been providing balancing energy continuously and reliably for over a year.
In an interview with our Regulatory Manager Sebastian Nitsche and Product Manager Filip Markert, we discuss how this path was shaped and what challenges Energy2market has to face in day-to-day balancing power operations.
Biomass package 2025: How to take advantage of the opportunities in the new tender design
The biomass package adopted at the end of January 2025 clearly focuses on making the plant portfolio more flexible for the second funding period. However, the demanding requirements in the legal text are also likely to lead to challenges in practice. You can find an overview here.
