Demand-charge check
How much of your bill is demand charges?
A commercial electric bill has two parts. Energy charges pay for the kilowatt-hours you use; solar lowers them. Demand charges pay for your highest 15-minute draw in the month; battery storage lowers them.
Demand charges often make up 30% to 70% of a commercial bill (NREL). Your bill's lines marked Facilities-Related Demand and Time-Related Demand show yours.
For comparison, the Monterey Park warehouse paid about $3,000 a month; with solar and battery storage its bill is projected at $500.
