1. Regulatory Ecosystem: TGSPDCL, TGREDCO & CEIG Norms
Successfully installing an EV charger in Hyderabad requires compliance with three primary state bodies:
1. TGSPDCL (Telangana State Southern Power Distribution Company Limited)
TGSPDCL governs electrical grid connections, service drops, transformer sanctions, and metering across Hyderabad and surrounding districts.
- LT-IX EV Charging Tariff (Low Tension): Designed for commercial charging setups drawing under $56\text{ kW}$ ($75\text{ HP}$). TGSPDCL provides a concessional single-part energy charge fixed at ₹6.00 per unit/kWh with ₹0 fixed demand charges, significantly cheaper than standard commercial LT-II rates (which reach ₹8.50–₹11.00/unit).
- HT-EV Tariff (High Tension – 11kV/33kV Feeder Connection): Tailored for high-power DC fast-charging plazas, fleet depots, and major IT park installations drawing over $56\text{ kW}$. High Tension energy charges sit at a baseline of ₹6.00 per kWh alongside a nominal demand fee of ₹100 per kVA per month.
2. TGREDCO (Telangana State Renewable Energy Development Corporation)
TGREDCO acts as the designated State Nodal Agency (SNA) for electric vehicle charging infrastructure under the Telangana Clean and Green Policy. Commercial EV charger installers must obtain an NOC or register site endpoints via TGREDCO’s single-window portal. Registration qualifies operators for state subsidies (under scheme guidelines) and lists the station on official public navigation applications.
3. CEIG (Chief Electrical Inspectorate to Government, Telangana)
Under Indian Electricity Rules and Central Electricity Authority (CEA) Safety Regulations, any commercial EV charging station featuring voltage levels above 250V (which includes all three-phase AC wallboxes and DC fast chargers) must undergo mandatory physical inspection and obtain a safety fitness certificate from the CEIG Telangana prior to energization.
