Understanding Demand Charges
Demand charges are based on your highest 30-minute kVA reading during the billing period. Just one spike can cost you thousands.
Common Causes of High Demand:
- Multiple machines starting simultaneously
- Poor power factor
- Uncoordinated production scheduling
- Compressor cycling
Did you know? We regularly find clients paying for 20-30% more
capacity than they actually need.
Typical Rates:
- Small Commercial: £6-10/kVA/month
- Medium Industrial: £8-12/kVA/month
- Large Industrial: £10-15/kVA/month
