HT Customers : Pain Points
TNEB’s New Regulations on HT Customers:
� Reduction in sanctioned load by 40%– 60%
• Eg. 1000kVA sanctioned load, reduced to
400kVA quota
� 2 days of power holiday per week
� Restricted usage between 6PM to 10PM
(unless purchased from power exchange)
� Significant cutback of total number of units
(kWh) to be consumed
� Heavy Penalties for non compliance
