Public EV Charging Station in Hyderabad | CPO Network & Location Guide
Greater Hyderabad—spanning the IT corridors of Cyberabad, the industrial nodes of Medchal and Patancheru, and the high-speed transit corridors of the 158-km Outer Ring Road (ORR)—has established itself as South Asia’s premier mobility transformation market. Driven by progressive state policy mandates, corporate ESG commitments, and widespread electric vehicle adoption across commercial taxi fleets, public transport buses, and personal commuters, the demand for accessible, high-speed charging infrastructure is at an all-time high.
Establishing a viable, profitable, and compliant public EV charging station in Hyderabad requires more than mounting a charger on a concrete pad. It demands a synchronized engineering framework combining land acquisition, utility grid load sanctions, high-power DC conversion hardware, cloud-based software management, and strict regulatory compliance:
This master blueprint details the regulatory frameworks, grid integration protocols, financial models, and execution procedures for developing and operating public EV charging stations across the Hyderabad Metropolitan Development Authority (HMDA) jurisdiction.
1. Regulatory & Policy Framework: TGREDCO, TGSPDCL & TGERC Directives
Developing public charging infrastructure in Telangana requires navigating guidelines established by state renewable energy agencies, distribution utilities, and electricity regulatory commissions.

TGREDCO State Nodal Agency (SNA) Mandates
The Telangana Renewable Energy Development Corporation Limited (TGREDCO)—formerly TSREDCO—acts as the designated nodal agency for electric vehicle infrastructure development:
- Public-Private Partnership (PPP) Land Allotment: TGREDCO aggregates prime government-owned land parcels—including TSIIC industrial parks, HMDA parking plazas, TSRTC bus terminals, and municipal sites—and tenders them to empanelled Charge Point Operators (CPOs) under revenue-sharing or ground-lease models.
- CPO Empanelment Framework: Operators must undergo technical and financial evaluation to join TGREDCO’s empanelled list, ensuring that deployed hardware meets national standards (BIS/ARAI certified) and supports open protocol communications.
- TSEV Unified Mobility App Integration: Public CPOs are required to transmit real-time telemetry—including station location, connector availability, live charging status, and tariff pricing—to TGREDCO’s central TSEV mobile platform via secure WebSockets.
TGSPDCL LT-IX / HT-IX Concessional EV Tariff
Under the regulatory orders of the Telangana Electricity Regulatory Commission (TGERC), TGSPDCL enforces a dedicated utility power tariff category specifically tailored for EV charging infrastructure:
- Concessional Energy Base Charge: LT-IX (Low Tension) and HT-IX (High Tension) tariff categories set the base electricity charge at ₹6.00 per unit (kWh) plus applicable electricity duties. This input rate is significantly lower than standard commercial C&I tariffs (which often exceed ₹10.00/kWh), providing favorable margins for public station operators.
- Dedicated High-Tension (HT) Connections: Public fast-charging plazas requiring total connected loads above 75 kVA receive dedicated 11kV or 33kV service lines, complete with outdoor step-down transformers and digital Time-of-Day (TOD) metering.
2. Technical Hardware Portfolio & Substation Microgrid Architecture
A high-utilization public charging hub must feature a versatile hardware lineup capable of serving personal passenger cars, commercial fleet cabs, electric two/three-wheelers, and heavy commercial transit vehicles.
