Large business tariffs

Large businesses tariffs are designed to meet the unique energy needs of our large business customers.

Demand tariffs

Most large business tariffs are demand-based, but the way demand charges apply can vary between tariffs.  Generally, it involves a measure of the largest amount of electricity you use at a point in time, during set hours, days or months.
