Since 2020, the Battery storage revenues<\/strong> in the German energy market have developed positively and risen continuously, which is attributable to various influencing factors and market trends. This positive dynamic shows that Battery storage<\/a> are increasingly being recognized as important players in the energy industry. Especially in the Primary control power market<\/strong> and on Spot market<\/strong> battery storage systems have taken on a new significance as a source of income for storage system operators.<\/p>\n\n\n\n

The marketing of primary control power (PRL) - also known as primary control reserve - has traditionally been the most lucrative option for battery storage systems. Their main task is to provide extremely Short-term fluctuations<\/strong> in the power grid and to keep the frequency of the power grid at a stable value (50 Hertz in Europe). However, the marketing of secondary control power (SRL), which normally stabilizes the power grid within 30 seconds to 5 minutes after a frequency deviation, is also increasingly becoming the focus of industrial battery operators.<\/p>\n\n\n\n

Rising battery storage revenues in electricity trading and on balancing energy markets<\/h2>\n\n\n\n

In the year 2021<\/strong> operators of storage systems with a capacity of 1 MW and a storage depth of 1 MWh were able to store around 136,000 euros<\/strong> on the PRL market. This figure rose in the year 2022<\/strong> to about 180,000 euros<\/strong> and by autumn 2024, operators of a two-hour storage system could even achieve around 195,000 euros<\/strong> per megawatt. All of these figures point to a sustained Strong demand<\/strong> and Volatile markets<\/strong> there. <\/p>\n\n\n\n

In comparison, exclusive marketing in the primary control power or secondary control power would only have had around 125,000 euros<\/strong> per megawatt. In electricity trading over the same period, there were around 145,000 euros<\/strong> per megawatt. These figures illustrate the yield dynamics that arise from the combination of different marketing strategies.<\/p>\n\n\n\n

Markets, battery systems and the right mix are crucial<\/h2>\n\n\n\n

The composition of the revenues varies depending on the storage duration: In two-hour systems, the revenues mainly come from secondary control power and electricity trading. One-hour systems, on the other hand, generate a relatively even distribution<\/strong> of revenues between primary control power, secondary control power and trading. These differences emphasize how strongly the Deployment strategy<\/strong> and Storage capacity<\/strong> can influence profitability. <\/p>\n\n\n\n

The primary control reserve (PRL) market has shown stable growth from 2021 to 2022. However, since 2023, there has been a convergence with the SRL market, which puts the PRL into perspective as a source of income. At the end of 2022 and beginning of 2023 in particular, spot market revenues also converged with those of the PRL market, allowing for greater strategic flexibility in the marketing of storage capacities.<\/p>\n\n\n\n

The revenue potential of the spot market also increased in 2022 and 2023. In some months, the spot market even generated higher revenues than the PRL market, which offers storage system operators additional options for Arbitrage transactions<\/strong> with Power trading<\/a> opened. The spot market primarily benefited from the rising spreads in Day-Ahead<\/a>\u2013 and the intraday market, making battery storage an attractive addition to the classic ancillary services market.<\/p>\n\n\n\n

Market alignment & factors influencing revenue development<\/h2>\n\n\n\n

The ongoing harmonization of the revenue potential for battery storage systems has given storage system operators more Flexibility in marketing<\/strong> and opened up new arbitrage opportunities in intraday trading. Various factors have favored this development:<\/p>\n\n\n\n
