Cut peak loads, reduce energy costs, increase production reliability. BESS smooths your load profile, optimises PV self-consumption and earns on the frequency regulation market.
Rising electricity prices, volatile markets and increasing grid congestion risk. Industrial facilities face triple pressure: energy costs are rising, supply security is not guaranteed and the new demand tariff penalises load spikes directly.
A BESS at the production site provides planning certainty: load spikes from machine start-ups are smoothed, PV electricity from the roof is buffered and production continues uninterrupted during grid disturbances.
Real-World Example
A metalworking facility with a press line has load spikes of 2 MW at shift start. BESS reduces the measured peak to 1 MW. The annual demand charge saving: approx. CHF 140,000.
Industrial machines create extreme inrush currents. A compressor draws 5 to 8 times its rated power at start-up. Presses, furnaces and CNC machines regularly push the power peak above the grid limit at shift start.
If the demand tariff rises, energy costs jump sharply. For industrial facilities with heavy machinery, this means: every uncontrolled machine start-up costs money directly.
At the same time, production interruptions can cost thousands per hour. A grid failure during active production causes rejects, machine damage and delivery delays.
With your own photovoltaic system and battery storage, a large share of electricity demand can be covered by renewable energy, significantly reducing CO₂ emissions from energy procurement.

Demand Charge Savings
Compressors, presses and furnaces create extreme load spikes at start-up. BESS automatically smooths your load profile and reduces the measured 15-minute peak.

Resilience & Backup Power
A grid outage during active production causes rejects and machine damage. BESS responds in milliseconds and protects critical processes. Much faster than any diesel generator.

Additional Revenue Around the Clock
Even outside production hours, the storage earns: ancillary services (frequency regulation), arbitrage, peak shaving and PV self-consumption optimisation run automatically.
If the demand tariff rises, energy costs jump sharply. For industrial facilities with heavy machinery, this means: every uncontrolled inrush current costs money directly. A BESS catches these peaks automatically.

BESS costs since 2022. The investment becomes increasingly attractive.
30 Rp./kWh
Industrial electricity price CH (2024). Self-consumption directly reduces procurement costs.
Peak Shaving for Production Facilities
Compressors, furnaces, presses and CNC machines often start simultaneously at shift change. BESS detects the load increase in milliseconds and discharges precisely. The 15-minute peak drops by 20-50%.
PV + Storage on Industrial Roofs
Large warehouse roofs offer space for PV systems. BESS stores the solar surplus and releases it during the night shift or during production peaks. Self-consumption rates rise above 80%.
Backup Power for Production Lines
Production interruptions cost thousands per hour. BESS responds in milliseconds during grid disturbances and bridges the outage until restoration. Faster and more reliable than diesel generators.
Ancillary Services Revenue
At night, on weekends and during production breaks, BESS capacity is available for the frequency regulation market. Primary, secondary and tertiary regulation generate predictable additional revenue without extra effort.

The sizing depends on the load profile, installed machine capacity and existing grid connection. For a medium-sized production facility, we typically calculate 0.5-5 MW of power and 1-10 MWh of capacity. NRG Solutions advises you in a free initial consultation on the optimal sizing.
No. In addition to the classic purchase (INVEST model), NRG Solutions also offers a RENTAL model. NRG finances, builds and operates the storage system. You benefit from day 1 without equity. Revenue sharing is arranged transparently.
Industrial facilities have particularly high inrush currents due to heavy machinery (presses, furnaces, compressors). These drive up the 15-minute peak demand. With the new demand tariff, this peak is billed explicitly and measurably. A BESS typically reduces these peaks by 20-50%.
Yes. BESS systems can be configured as backup power supply. In the event of a grid failure, the system responds in milliseconds and bridges the outage. Unlike diesel generators, a BESS requires no start-up time and no fossil fuels. The backup function runs in parallel with peak shaving and ancillary services.
Yes. The main applications in industrial facilities (peak shaving, demand charge reduction, ancillary service revenue, backup power) work independently of solar. A PV system further increases profitability through self-consumption optimisation but is not a prerequisite.
