More revenues, lower grid costs – with co-location
We combine renewable generation with storage solutions – unlocking maximum efficiency, profitability, and long-term regulatory compliance.
Why co-location matters now
Falling market values for renewables, limited grid connections, and increasing cost pressure make co-location a key strategy. Combining generation and storage increases revenues, reduces capital (CAPEX) and operating expenses (OPEX), and enables more flexible asset management. At the same time, co-location is supported by regulation, strengthening the future viability of your project.
Technically, different coupling setups (AC or DC), prioritization logics for oversizing at the grid connection point, and green or gray operating models allow tailored implementation. We ensure compliance with all regulatory requirements — from EEG to EnWG.
Co-location technology and regulation at a glance
Co-location projects often involve oversizing at the grid connection point, meaning the combined output of PV and storage exceeds available grid capacity. In such cases, an intelligent prioritization logic is required to ensure both assets are efficiently operated and marketed.
AC and DC coupling differ technically: AC is easier to implement, while DC enables more efficient overall use but requires more complex integration. The operating model also plays a role: in green co-location, the storage may only use electricity from the generation asset; in gray co-location, it may also draw grid power, opening significantly more commercial opportunities.

FAQ
Co-location: Questions and answers
How does a battery improve the profitability of my PV system in a green co-location setup?
A battery can store surplus PV generation and shift it to times with higher prices, allowing more electricity to be sold at better market conditions. It helps avoid negative prices and increases grid supportiveness. In addition, it can unlock extra revenue streams in balancing markets.
Which commercial models are possible for co-located projects?
Co-located projects offer a wide range of commercial models. From traditional PPAs to tailored tolling agreements, we advise you individually and develop the right solution for your project.
Which markets are accessible with gray co-location?
A storage asset with grid access rights (gray co-location) can operate flexibly across all relevant markets: spot, FCR, aFRR, intraday, and arbitrage. This enables significantly higher revenue potential compared to generation-only projects. Our algorithms optimize bidding strategies across markets.
Do you offer tolling models for storage?
Yes. Through partners, we can provide both partial and full tolling models. This secures fixed revenues while outsourcing trading risks. Settlement is handled seamlessly via our platform.
What needs to be considered in green co-location?
In green co-location, the battery may only use renewable electricity — grid charging is excluded. This reduces flexibility and can cost up to two-thirds of the revenue potential. Nevertheless, we provide optimized strategies for this setup, fully aligned with regulatory requirements.
