TGERC Notifies Rooftop Solar Regulations for 2025 – EQ
Summary:
—
### **1. Scope & Applicability**
– Applicable to **prosumers** (consumers who also generate electricity) in Telangana.
– Covers **residential, commercial, industrial, institutional, and government buildings**.
– Applies to rooftop solar systems **up to a specified capacity** (likely 500 kW–1 MW).
### **2. Net Metering & Gross Metering**
– **Net Metering:** For systems up to a certain capacity (e.g., up to 500 kW).
– Unused energy exported to grid credited to consumer’s account at **approved tariff**.
– **Net accounting period** likely monthly or yearly.
– **Gross Metering:** Possibly for larger systems or specific consumer categories.
– All solar energy exported to grid at **feed-in tariff**; all consumption imported from grid at retail tariff.
### **3. Capacity Limits**
– May specify **maximum capacity as a percentage of contract demand** (e.g., 80%–100%).
– **Capping** on total rooftop solar capacity per DISCOM feeder/substation to maintain grid stability.
### **4. Subsidies & Incentives**
– **Central Financial Assistance (CFA)** as per **PM-Surya Ghar Muft Bijli Yojana**.
– **State-level incentives** (possibly additional to CFA).
– **Accelerated depreciation** for commercial/industrial consumers.
### **5. Simplified Procedure**
– **Online application** via DISCOM portal.
– **Standardized agreement** for net metering.
– **Timeline for approval and commissioning** (e.g., 15–30 days).
– **Single-window clearance** for systems up to certain capacity.
### **6. Technical & Safety Standards**
– Compliance with **CEA regulations** and **IEEE/IS standards**.
– **Metering requirements:** ABT meters for net metering.
– **Grid connectivity** as per **State Grid Code**.
– **Safety measures:** Isolation, earthing, and protection systems.
### **7. Tariff & Billing**
– **Feed-in tariff** for gross metering determined by TGERC.
– **Banking charges** (if applicable) for net metering.
– **Billing cycle** and settlement process clearly defined.
### **8. Roles & Responsibilities**
– **DISCOMs:**
– Provide connectivity, net metering, and energy accounting.
– Ensure grid stability and safety.
– **Consumer:** Maintain system, ensure safety, provide access for inspection.
– **TGERC:** Monitor implementation, resolve disputes, review tariffs.
### **9. Group Net Metering & Virtual Net Metering**
– Possibly introduced for **housing societies, institutions, and multiple consumers** under single connection.
– **Virtual net metering** for consumers with multiple premises.
### **10. Renewable Purchase Obligation (RPO)**
– Rooftop solar generation may count toward DISCOM’s RPO compliance.
– **Green energy certificates** possibly tradable.
