Co-location battery storage system (BESS)
Using co-location battery energy storage systems (BESS) for the energy transition!
Co-location battery storage systems use the grid connection of new or existing renewable energy systems. ESFORIN markets this electricity in times of increased demand and more attractive electricity prices - whether on the wholesale market or in balancing power!
Co-location battery storage as an opportunity
Making optimum use of network connections
Applying for new grid connections for stand-alone battery storage systems can be very time-consuming and may even be rejected due to local grid bottlenecks. At the same time, the value of renewable energies - especially solar parks - is decreasing. This is due to the rapid expansion of photovoltaic capacity and the lack of battery storage capacity, an overall decline in demand for electricity and the lack of flexibility to adapt it (especially in Germany).
Co-location and grid connection
The solution to the problems described is the installation of co-location battery storage systems at existing renewable energy grid connections. Co-location battery storage systems rely on the grid connection of new or existing renewable energy systems. Accordingly, they can flexibly adapt their feed-in and feed-out to electricity demand and electricity exchange prices.
In principle, battery storage systems can also be installed on existing, oversized industrial grid connections and old power plant sites. However, a lack of space and fire safety regulations are usually the limiting factors here, and there are two different categories of co-location battery storage systems:
Co-location battery storage systems that only use the physical grid connection and increase the market value of renewable energies. And, innovation tender systems that receive targeted funding as part of the EEG's innovation tender.
Direct marketing and cross-market optimization of battery energy storage systems (BESS)
The marketing potential of co-location battery storage systems is often not sufficiently exploited, because simply feeding electricity in and out depending on the exchange price is not enough. At ESFORIN, we offer end-to-end solutions for co-location battery storage systems, including EEG direct marketing, flexibility marketing and balancing group management. We take care of your energy management processes and marketing for the best possible results. And, you take care of the operation and maintenance of your battery storage system.
Our company is a leading flexibility marketer on the short-term electricity markets with over 20 system types and extensive expertise in battery energy storage systems (BESS). Since 2016, we have been reacting to price fluctuations in milliseconds on the intraday market for our customers using individually programmed algorithms and thus also to the fluctuating supply of renewable energies. In doing so, we can coordinate both positive and negative flexibilities, i.e. supply and demand response management, with market prices. This expertise is particularly essential when discharging battery storage systems and offers a decisive competitive advantage in individual 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 systems in real time: Intraday, day-ahead, primary or secondary power. This is how we maximize the efficiency, yield and service life of the co-location batteries!
The use of a battery storage system as part of a "real" co-location can more than double the market value of PV electricity (see diagram). The decisive factor here is correct dimensioning, which ESFORIN is happy to help with.

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 cooperation with sonnen shows that even smaller aggregated home storage systems can be marketed intelligently. We are convinced that together we can drive forward a green and secure energy system. Together we will also find the optimum marketing model for your battery storage system: we will find the ideal dimensions for you and simulate historical marketing results.
