Co-location battery storage system (BESS)
Leverage Co-Location Battery Energy Storage Systems (BESS) for the Energy Transition!
Co-location battery storage systems utilize the grid connection of new or existing renewable energy plants. ESFORIN markets this electricity during periods of increased demand and when electricity prices are more attractive—whether on the wholesale market or as balancing power!
Co-location battery storage as an opportunity
Making the Most of Network Connections
Applying for new grid connections for stand-alone battery storage systems can be very time-consuming and may even be denied due to local grid bottlenecks. At the same time, the value of renewable energy—especially from solar farms—is declining. This is due to the rapid expansion of photovoltaic capacity, a shortage of battery storage capacity, an overall decline in electricity demand, and the inability to adjust supply flexibly (particularly in Germany).
Co-location and grid connection
The solution to the problems described is the installation of co-located battery storage systems at existing grid connections for renewable energy sources. Co-location battery storage systems rely on the grid connection of new or existing renewable energy facilities. This allows them to flexibly adjust the feed-in and feed-out of electricity to match electricity demand and electricity exchange prices.
In principle, battery storage systems can also be installed at existing, oversized grid connections at industrial sites and old power plant locations. However, space constraints and fire safety regulations are usually the limiting factors in such cases. There are two different categories of co-located battery storage systems:
Co-located battery storage systems that simply utilize the physical grid connection and increase the market value of renewable energy. And, projects under the EEG’s innovation tender program that receive targeted funding.

Direct Marketing and Cross-Market Optimization of Battery Energy Storage Systems (BESS)
The marketing potential of co-location battery storage is often not fully realized, because simply feeding electricity into and out of the grid based on market prices is not enough. At ESFORIN, we offer end-to-end solutions for co-location battery storage, including direct marketing under the Renewable Energy Sources Act (EEG), flexibility marketing, and balancing group management. We handle your energy management processes and marketing to ensure the best possible results. And you take care of the operation and maintenance of your battery storage system.
Our company is a leading provider of flexibility services in the short-term electricity markets, with over 20 types of facilities and extensive expertise in battery energy storage systems (BESS). Since 2016, we have been using custom-programmed algorithms to respond to price fluctuations on the intraday market for our customers within milliseconds—and thus also to the fluctuating supply of renewable energy. In doing so, we can align both positive and negative flexibility—that is, supply and demand response management—with market prices. This expertise is particularly essential when discharging battery storage systems and provides a decisive competitive advantage in individualized marketing.
Our allocation algorithm continuously takes into account the technical specifications and limitations of the battery storage systems and selects the most profitable market for stand-alone battery storage in real time: intraday, day-ahead, primary, or secondary power. This is how we maximize the efficiency, return on investment, and service life of the co-location batteries!
The use of a battery storage system as part of a „true“ co-location setup can more than double the market value of PV electricity (see chart). Proper sizing is crucial here, and ESFORIN is happy to assist with this.
PV Co-Location Yield
It is not only the individual marketing of large battery energy storage systems (BESS) that is profitable for the energy transition. Our collaboration withsonnen shows that even smaller, aggregated home storage systems can be marketed intelligently. We are convinced that together we can advance a green and secure energy system. Together, we’ll also find the optimal marketing model for your battery storage system: We’ll determine the ideal sizing for you and simulate historical marketing results. Feel free to contact us!
