Large-scale energy storage
Large-scale energy storage makes the electricity grid more flexible, because energy can be buffered temporarily at the MWh scale and then made available again very quickly. For energy parks, grid operators, and large consumers, this is a key technology for smoothing peaks and troughs in supply and demand, limiting congestion, and making the best possible use of renewable generation. In practice, for ChargeBlock this mainly involves battery energy storage systems (BESS) that provide grid services and create value in energy markets, under strict requirements for safety, availability, and controllability.

Why MWh-scale storage is becoming indispensable in the grid
As more wind and solar energy is generated, variation in production increases, while electrification continues to drive demand higher. Without sufficient flexibility, this quickly leads to curtailment (switching off generation), higher imbalance costs, and heavier loading of transformers and cables.
With storage at MWh scale, a site can absorb overproduction and feed it back later, making grid reinforcement less urgent and improving the use of available connection capacity. The specialists at ChargeBlock advise on how a BESS combines fast power response (kW/MW) with energy capacity (MWh), so that both short frequency events and longer price and congestion patterns can be managed.
The most frequently asked questions about battery containers
How does a battery container help with grid congestion and peak load?
Our battery containers are used for peak shaving, zero feed-in, and behind-the-meter optimization. By deploying stored energy intelligently, you prevent exceeding contracted capacity and reduce dependence on the grid. This creates room for expansion without immediate grid reinforcement.
Can the battery container be integrated with our existing EMS or aggregator?
Is battery storage financially feasible for our organization?

Grid stabilization with FCR, aFRR and fast power response
Because batteries can respond within milliseconds to seconds, they are highly suitable for frequency control. In FCR (Frequency Containment Reserve), the system automatically stabilizes grid frequency around 50 Hz. With aFRR (automatic Frequency Restoration Reserve), power is then dynamically adjusted to restore the balance between production and consumption.
In this context, state-of-charge management, round-trip efficiency, degradation, and availability are decisive: a BESS must be able to charge and discharge within contractual limits, while at the same time sufficient stored energy must remain available to support longer activations.

Trading markets: imbalance, arbitrage and energy management
In addition to grid services, storage can also generate revenue through market optimization. In imbalance trading, deviations between forecast and actual production or consumption are used; a battery can immediately compensate for shortages or absorb surpluses. In arbitrage, it is charged when the price is low and discharged when the price is high, for example based on day-ahead, intraday, or quarter-hour prices.
The final return depends on the spread, the number of cycles, and practical constraints, such as grid or export limits. ChargeBlock supports the choice of forecasting and an EMS (Energy Management System) to determine whether strategies reinforce each other or instead compete for the same capacity.

System architecture: from battery container to grid connection
A large-scale BESS consists of battery modules, a power conversion system (inverters), a transformer, protections, and control systems. In many projects, a battery container from ChargeBlock serves as the modular building block, because it is scalable and transportable and is generally designed for outdoor installation.
In the design, choices around AC or DC coupling, redundancy, cooling (HVAC or liquid), fire detection and fire suppression, and the interface with the medium-voltage grid connection play a major role. This also includes protection studies and compliance with the grid code. In addition, metering and telemetry requirements from TSO/DSO and market platforms are often decisive for the final configuration.

Safety, permits, and service life: where projects fail or succeed
In terms of safety, the main focus is on controlling the risk of thermal runaway, with attention to compartmentalization, ventilation, fire suppression concepts, and clear incident response procedures. Permitting processes generally require substantiation of noise levels, spatial integration, grid impact, and external safety aspects.
For the business case, degradation, warranty conditions, maintenance, and availability are decisive. By applying realistic dispatch that takes temperature, C-rate, SoC windows, and connection limitations into account, ChargeBlock helps maintain service life for longer and prevent revenue from FCR/aFRR or arbitrage from declining due to unexpected derating.
This makes large-scale energy storage both a grid instrument and a market asset: those who design the system integrally and control it intelligently with ChargeBlock limit curtailment, reduce imbalance risk, and strengthen grid stability.

Large-scale Energy Storage
Battery container
Maximum flexibility in one MV skid
What makes this system distinctive is that flexibility in power and grid voltages is combined with maximum compactness. For large-scale projects, where different C-ratios and grid voltage levels are required, we have developed our own 20ft and 40ft MV skids. These can be deployed from 2 MW to 10 MW and are suitable for grid connections from 6 kV to 35 kV.
This integration keeps the system compact while also making it broadly applicable across a range of energy infrastructures.
In collaboration with CATL, we use the latest battery technology, including cells up to 565 Ah. This allows us to achieve up to 6 MWh of storage capacity in a 20ft container. This technology provides not only very high energy density, but also a high level of safety and minimal degradation in the first years, resulting in a smaller footprint and long-term performance.
