Key Regulatory Tenets:
- De-licensed Service Activity: In accordance with Central Electricity Authority (CEA) guidelines and state notifications, setting up an EV charging station in Telangana is legally classified as a service rather than the resale of electricity. Investors do not require a power distribution license.
- Concessional EV Power Tariffs: The Telangana State Electricity Regulatory Commission (TSERC) mandates a specialized LT/HT EV Charging Station tariff category. This rate is priced below standard commercial tariffs to maintain CPO profitability and lower driver charging costs.
- Single-Window Clearing Portal: TGREDCO manages an online clearing mechanism for site registration, facilitating streamlined coordination between the operator and power distribution companies (DISCOMs).
Strategic Site Selection & Key Charging Corridors
Site selection determines long-term utilization rates. In Telangana, charging demand is concentrated across three primary asset classes.
TELANGANA EV CHARGING LOCATION TYPES
[ URBAN METROHUBS ] [ HIGHWAY CORRIDORS ] [ COMMERCIAL / RETAIL ]
