A handful of intervals sets the whole bill. P05 · 125 kW – 2 MW reduction
What a demand charge actually bills you for

On top of the per-kWh energy charge, utilities like BC Hydro bill commercial and industrial accounts a demand charge, based on your single highest 15-minute draw all month. One short spike sets that number for the next 30 days. Our batteries shave the spike, so a smoother load curve means a lower bill.

LOAD PROFILE  //  BEFORE & AFTER STORAGE
700 → 320 KW
Before — grid only Two equipment spikes set the whole month’s demand charge

After — with Arctium BESS The battery covers both spikes before the grid ever sees them
