Battery Energy Storage Systems (BESS) not only store energy for use when it’s needed most – whether during peak demand, outages, or to harness excess power from solar, wind or the grid.
In combination with an intelligent Energy Management System (EMS), they can also provide a long list of applications that reduce energy costs, creates new revenue streams and enable and protect daily operations.
- Modular and Scalable design
- Energy Management System made in EU
- PFAS-Free Fire Suppression Technology
Applications
Front-of-the-Meter (FTM)
Grid-side / utility-scale, mostly revenue and grid-service driven:
- Energy arbitrage — buy/store energy when wholesale prices are low, discharge/sell when high (day-ahead and intraday trading)
- Frequency Containment Reserves (FCR) — fast automatic response to keep grid frequency stable (e.g. FCR-N, FCR-D up/down)
- Frequency Restoration Reserves (FRR) — automatic (aFRR) and manual (mFRR) balancing services
- Fast frequency response (FFR) / synthetic inertia — sub-second injection to stabilize frequency on low-inertia grids
- Voltage support / reactive power (Q) regulation — hold voltage within limits locally
- Capacity market / firm capacity — being available as guaranteed capacity when the system needs it
- Reserve & ancillary services (stödtjänster) — the broader basket of Transmission System Operator (TSO) / Distribution System Operator (DSO) support products
- Renewable firming & smoothing — stabilize variable solar/wind output, reduce ramp rates
- Curtailment reduction / renewable time-shifting — capture would-be-wasted generation and release it later
- Congestion management & grid-investment deferral — relieve constrained lines and postpone transmission/distribution upgrades
- Local flexibility markets — sell flexibility to the DSO where the grid is tight
- Black start — restart parts of the grid after an outage
- Peaker replacement — cover system peaks instead of fossil peaking plants
Behind-the-Meter (BTM)
Customer-side, mostly cost savings and resilience:
- Peak shaving / demand-charge reduction — cut the expensive kW peaks on your bill
- Load shifting / time-of-use optimization — move consumption to cheaper hours
- Self-consumption optimization — store your own solar (or off-peak energy) for use after dark
- Backup power / UPS / reserve power (reservkraft) — ride through outages, protect critical loads
- Grid-capacity relief — add load, machines or chargers behind an existing connection instead of paying to upgrade it
- EV charging buffering — deliver fast charging without a grid reinforcement (Sparq SuperCharger / MobileCharger)
- Power quality — voltage support, flicker and harmonic mitigation, protection from dips/sags
- Genset / diesel replacement or hybridization — cut fuel, noise and emissions on weak-grid or off-grid sites
- Off-grid / island operation — run fully independent of the grid where needed
- Phase balancing — even out unbalanced three-phase loads
- Energy communities & shared storage — pool storage across buildings or members
