Glossary
Demand charge
The part of a business electricity bill based on the highest power the site draws in the month, separate from the energy it uses.
Notified maximum demand
The capacity a site has agreed with its supplier. Going over it adds a charge to the bill.
Peak and time-of-use
Electricity costs more per unit in the weekday morning and evening peaks. A battery charged off-peak covers those hours.
Embedded generation
Power produced on your own site, connected on your side of the meter.
Distribution board
The electrical board the solar plant connects into.
Section 12B
A tax allowance that lets a business deduct the cost of a solar plant it owns, up to 1 MW, in the first year.
