A BESS is not a single product – it is a platform. Depending on the site, load profile and objectives, multiple use cases can be realized simultaneously and revenue streams stacked.
Store PV surplus and use it when your business needs it.
02Cut load peaks and significantly reduce grid charges.
03Provide balancing energy for Swissgrid, attractively compensated.
04Scale charging infrastructure without grid reinforcement.
05Pure energy trading: buy low, sell high.
06Secure critical processes during grid disturbances.
07Grid support to avoid grid expansion.
08Meet regulatory requirements and reporting obligations.
A PV system generates electricity during the day, often when on-site consumption is low. Without storage, the surplus flows into the grid, even when feed-in tariffs are low. A BESS stores the surplus and releases it when the business actually needs the energy.
The result: The self-consumption rate increases significantly, grid purchases decrease, and the profitability of the PV system improves substantially.
Result
Self-consumption rate typically increased from ~30% to up to 70–90% (depending on load profile, PV size and storage dimensioning)
Industrial electricity customers pay grid charges based on the highest measured 15-minute demand peak. Individual spikes – from machine starts, furnaces or compressors – drive costs disproportionately upward.
A BESS detects these peaks in real-time and discharges strategically to keep the grid demand below a defined threshold. Grid charges are sustainably reduced.
Result
Peak demand reduction typically 20–50%, depending on load profile and storage dimensioning.
Swissgrid requires balancing energy to maintain the grid frequency at 50 Hz. Pre-qualified BESS systems can provide this service automatically – faster and more precisely than conventional power plants.
Participation in the SDL market (FCR, aFRR) generates predictable revenue. NRG Solutions handles pre-qualification, marketing and settlement through its own balancing group.
Result
Additional revenue stream from Swissgrid payments, fully automated process
Fast-charging stations create extreme power peaks of up to 500 kW per charging point. Multiple simultaneous charging sessions can quickly exceed the available grid connection capacity. Grid reinforcement is expensive and takes months.
A BESS buffers the charging power: it charges during low grid load and supports during peak demand. This enables building charging infrastructure without upgrading the grid connection.
Result
Scalable charging infrastructure without grid expansion, immediately deployable
Spot market electricity prices fluctuate significantly throughout the day – low at night and weekends, high during daytime and evening. A BESS charges during low-price periods and discharges when prices rise.
The prerequisite is direct market access through a dedicated balancing group. NRG Solutions provides this access and optimizes trading cycles automatically through its proprietary EMS.
Result
Revenue from price spreads, direct market access via own balancing group
Grid outages are rare, but the consequences can be massive: production interruptions, data loss, quality issues. A BESS responds within milliseconds and bridges grid disturbances uninterrupted. That is faster than any diesel generator.
Unlike conventional UPS systems, a BESS is multifunctional: during normal operation it generates revenue through peak shaving or ancillary services; during outages it secures the power supply.
Result
Seamless backup during grid outages, no production interruptions
Distribution network operators face the challenge of managing grid congestion without the expense of building new lines. A BESS can strategically absorb peaks, compensate forecast deviations and locally improve grid stability.
For site operators this means: additional revenue through grid service contracts with the local distribution network operator.
Result
Avoided grid expansion, additional revenue from NDL contracts
Cantonal energy laws, MuKEn (Cantonal Model Regulations in the Energy Sector) and large consumer regulations increasingly require proof of efficiency measures and renewable self-consumption. A BESS combined with PV enables meeting these requirements.
Additionally, a BESS improves the CO₂ footprint of the site, as less grid electricity – and therefore less fossil electricity – is consumed.
Result
Meet regulatory requirements, improve CO₂ footprint
