Jain said several states had increased electricity tariff by up to 20-30 per cent last year but in Delhi, no power hike was allowed in 2015.
The government's stand came amid the demand for tariff hike by all three power distribution companies, citing rise in their expenses.
"Like last year, we will also not allow hike in electricity tariff this year," the power minister said while addressing representatives of Residents Welfare Associations (RWAs) at a one-day training workshop on energy conservation at Delhi Secretariat.
The Delhi government gives a subsidy of around Rs 1,500 crore every year on power consumption due to which the electricity bills are slashed by half.
