A battery storage system responds in milliseconds to grid outages. No interruption, no diesel, no startup delay. And during normal operation, it generates revenue.
Grid outages, voltage dips, and frequency fluctuations cost companies millions every year. Production lines halt, data is lost, cold chains break. Conventional solutions like diesel generators need 10 to 30 seconds to start up. For many processes, that is too slow.
A battery energy storage system (BESS) responds in milliseconds. The switchover is so fast that connected devices and processes experience no interruption. And unlike a conventional UPS or diesel generator, the BESS does not sit idle: during normal operation, it actively generates revenue through peak shaving, ancillary services, and arbitrage.
Dual-Use Principle
A BESS is simultaneously a backup power solution and a revenue source. During normal operation, it optimizes your electricity costs. During a grid outage, it protects your critical processes. The backup power function incurs no additional costs.
Diesel generators have been the standard for backup power for decades. They have their place, but also clear disadvantages: slow startup time, fossil fuel, regular maintenance, noise, and emissions. And above all: they sit idle 99% of the time and still cost money.
A BESS reverses this model. It is active during normal operation, generates revenue, and provides the backup power function as an additional capability. No startup time, no emissions, minimal maintenance.
Hybrid Solution Possible
BESS and diesel can also work together. The storage bridges the critical first seconds without interruption. The diesel takes over during longer outages. This way you combine the best of both worlds.
ms
Millisecond Response
BESS responds in milliseconds to grid outages and voltage dips. No interruption, no data loss, no production halt. Faster than any diesel generator, faster than conventional UPS systems.
Multi
Multifunctional
Unlike conventional backup power solutions, a BESS earns money during normal operation. Peak shaving, ancillary services, and arbitrage run in parallel. The backup power function is an additional safeguard at no extra cost.
0 L
No Diesel Required
No fossil fuel, no emissions, no engine and tank maintenance. BESS is instantly ready, with no startup time. And unlike diesel: no fuel degradation problem from standing idle.
01
Grid Monitoring
The EMS monitors grid voltage and frequency in real time. It detects voltage dips, frequency deviations, and grid outages within milliseconds.
02
Instant Takeover
During a grid outage, the BESS takes over power supply without interruption. The switchover occurs in milliseconds. Critical processes continue as if nothing happened.
03
Load Supply
The storage supplies the connected loads with power. The duration depends on storage capacity and actual consumption. Typical range: minutes to hours.
04
Return to Normal Operation
Once the grid is stable again, the BESS synchronizes and hands the load back. It then recharges and returns to normal multi-use operation.
Data Centers and IT Infrastructure
Server outages cost thousands of francs per minute. BESS bridges grid outages without interruption and gives diesel generators time to start up, or makes them entirely unnecessary.
Production and Manufacturing Lines
A voltage dip of just a few milliseconds can halt an entire production line. BESS buffers seamlessly and prevents costly production downtime and material losses.
Food and Pharmaceutical Industry
Cold chains and temperature-critical processes must not be interrupted. BESS ensures uninterrupted power supply and protects against spoilage and compliance violations.
Hospitals and Critical Infrastructure
Life-support systems, operating rooms, and medical equipment need uninterruptible power supply. BESS responds faster than backup diesel generators and bridges the critical first seconds.

A battery storage system responds in milliseconds to voltage dips and grid outages. The switchover is so fast that connected devices and processes experience no interruption. For comparison: a diesel generator needs 10 to 30 seconds to start up.
The bridging duration depends on storage capacity and actual consumption. With typical configurations, between 15 minutes and several hours. BESS can also serve as a bridge until a diesel generator or alternative grid takes over. NRG Solutions dimensions the storage to match your requirements.
A conventional UPS (uninterruptible power supply) is a pure backup system that provides no benefit during normal operation. A BESS actively generates revenue during normal operation through peak shaving, ancillary services, and arbitrage. The backup power function is an additional safeguard at no extra cost. Furthermore, BESS offers significantly higher capacities than typical UPS systems.
In many cases, yes. For short to medium outage durations (up to several hours), a BESS can fully replace the diesel generator. For very long outages, it can serve as a bridge until the diesel starts. The advantage: no emissions, no fuel storage, no startup time, less maintenance.
The costs depend on the required power rating and bridging duration. Since a BESS generates revenue during normal operation through peak shaving, ancillary services, and arbitrage, the effective additional costs for the backup power function are low to zero. NRG Solutions calculates the business case individually.
