LT or HT? How to decide

## The rule Above 150 kW, HT is required. Below that, it's a choice. ## What changes on HT - Lower energy rate per unit. - Demand charges on kVA instead of fixed charges on kW. - Time-of-day charges: more in peak hours, a rebate at night. - You own and maintain the substation, and transformer losses are billed to you. ## When HT pays High, steady consumption and a good power factor make HT attractive.
