Choose what you already have and what you want to develop. Everything, existing batteries, solar, HVAC, flexible loads and truck charging, can be connected to Stroem's intelligence layer (SES). Set a capacity to 0 to leave an asset out. Estimates only; a pre-study on your metered data gives the bankable numbers.
A Stroem specialist will contact you to qualify the opportunity and plan the next step.

Your assets are already in place. The figure above is the extra value Stroem's optimizer creates on top of what the assets earn today: ancillary services, spot arbitrage, load flexibility and a self-consumption uplift.
Please add your name and an email or phone number. Stroem needs to be able to reach you to qualify the opportunity.
When you send, your email app opens with the request addressed to Stroem; just press send. A Stroem specialist then contacts you to qualify the opportunity. Estimates only, built on Stroem reference cases and 2025 Danish market levels; a pre-study on your metered data gives the bankable numbers. No commitment.
Assumptions used in this estimate
Solar CAPEX (new): 2,500 DKK/kWp; existing solar: no CAPEX
BESS CAPEX (new): 1,250 DKK/kWh at 4-hour duration; existing BESS: no CAPEX, integration only
Auto battery sizing: 80% of amperage headroom (A × 400 V × √3), max 1 MW
Development & advisory fee: 10% of CAPEX; onboarding from 150,000 DKK when all assets exist
Ancillary services: 1,200 DKK/kW/yr (2025 level); optional degradation of 5%/yr
Spot arbitrage: 440 DKK/kW/yr
Solar: 950 kWh/kWp, up to 80% self-consumed, capped at 60% of consumption, valued at 0.90 DKK/kWh; +10% optimizer uplift counted in existing-asset mode
HVAC flexibility: 300 DKK per controllable kW / yr
Other flexible consumption: 450 DKK per flexible kW / yr
Electric trucks: ~90 MWh charging/truck/yr shifted to cheap hours at ~0.20 DKK/kWh → 18,000 DKK/truck/yr
Truck chargers: 250 DKK per kW of charger capacity / yr (peak shaving + load flexibility)
Backup power: avoided outage cost at 75 DKK/kWh unserved, ~0.4 outage hours/yr on average load; autonomy shown from battery energy
Operations & platform: 2.5% of CAPEX per year, minimum 40,000 DKK
