Darmstadt-based company strengthens marketing of storage systems and renewable energies
Darmstadt-based citiworks AG successfully concluded the 2025 financial year and set an important course for the further development of the energy market. The company, which specializes in highly automated processes in energy trading and the marketing of energy plants, storage facilities, and energy flexibility solutions, continued its strategic direction in a dynamic market environment.
Despite lower prices on the energy markets, citiworks was able to increase its earnings. Revenue declined from €1.872 billion in the previous year to €1.620 billion due to price changes. However, net income improved from €1.9 million to €2.1 million.
“Energy markets are becoming more volatile, decentralized, and complex. This makes it all the more important to develop the right capabilities early on,” explains citiworks board member Christian Stewens. These capabilities include, in particular, a strong business with Power Purchase Agreements (PPAs), the marketing of flexibility and storage, and highly automated processes in energy trading. “The fact that we were able to combine this approach with a very good annual result confirms our strategic direction.”
Long-term green energy solutions remain in demand
The business with Power Purchase Agreements also continued to develop successfully. Together with ENTEGA AG and ENTEGA Plus GmbH, citiworks concluded additional PPA contracts for wind, solar and hydropower plants with a volume of approximately 0.9 terawatt hours.
This meant that business remained at a high level after an exceptionally strong previous year. Together with ENTEGA, citiworks supports companies and municipalities in achieving their climate goals through long-term green electricity solutions.
Another focus was on expanding the technical infrastructure for connecting, controlling, and marketing energy flexibilities. With the increasing expansion of renewable energies and the growing importance of battery storage, these options are becoming ever more crucial for the energy system.
citiworks developed new products for marketing battery storage systems. These include models where storage systems are deployed in an economically optimized manner across various markets – for example, for ancillary services as well as in day-ahead and intraday trading.
New IT systems for automated energy trading
In parallel, citiworks continued to invest in modern trading processes and digital systems. A key step is the introduction of a cloud-based energy trading and risk management system. This is intended to make trading processes more efficient, flexible, and highly automated.
“By modernizing our system landscape, we are consistently developing our retail-related IT,” says Markus Nagel, Board Member for Retail and IT at citiworks. “This creates the conditions for us to further automate processes, implement new requirements more quickly, and provide even better support to our internal and external customers.”
With the expansion of storage marketing, green electricity solutions and digital trading platforms, citiworks sees itself well positioned for the next phase of the energy transition.
