A battery generates revenue by optimizing your energy consumption and contributing to the stability of the power system through participation in reserve markets. SundayOS ensures maximum uptime and return on investment.

We started testing battery solutions with Sunday Power in 2023 and are now pleased to take the next step with our first large-scale battery project. With Battery as a Service, we can adopt the technology without tying up capital or taking on operational responsibility. The interaction between solar installations and batteries is a positive contribution to our strategy of developing energy-efficient and sustainable industrial real estate.

Choosing Battery as a Service from Sunday Power was a natural decision for us. They combine strong technological expertise with a simple and attractive model for value creation. Through our existing collaboration in solar energy, we have experienced their ability to maximize the value of our assets. We now look forward to taking the next step together in a new and exciting project.
