What is reactive energy?
Reactive energy appears when certain electrical systems, especially motors and inductive equipment, draw power in a way that is less efficient for the grid. Distributors can bill for that inefficiency once it crosses the relevant threshold.
For many owners, this is the line they notice only after months of unexplained overpayment.
Which businesses are most affected
Reactive energy is most common where motors, compressors, and similar equipment run regularly.
- Restaurants and bars with heavy refrigeration and extraction.
- Hotels with pumps, HVAC, and larger building services.
- Workshops, laundry operations, and machinery-heavy sites.
- Businesses that have never installed or reviewed power factor correction equipment.
How businesses usually address it
The usual solution is not guessing at tariffs. It is identifying the equipment causing the issue and deciding whether capacitor-bank style correction or electrical review makes economic sense.
