Definition
CEA Connectivity Regulations are issued by the Central Electricity Authority (CEA) of India and govern the technical requirements for connecting utility-scale solar plants to State Transmission Utility (STU) and Central Transmission Utility (CTU, PGCIL) networks.
Key Requirements
- LVRT (low-voltage ride-through) curve.
- Frequency operating range typically 47.5–51.5 Hz.
- Reactive power capability at point of connection.
- Anti-islanding per IEC 62116.
- Real-time SCADA reporting.
Key Takeaways
- CEA Connectivity Regulations govern utility-scale solar grid interconnection in India.
- Applies to plants ≥ 5 MW (STU) or ≥ 50 MW (CTU).
- LVRT, frequency, reactive power, SCADA requirements.
- 6–18 month process including system impact study.
- DISCOM net metering for smaller systems instead.
Frequently Asked Questions
4 commonly searched questions about CEA Connectivity Regulations.
What are CEA Connectivity Regulations?
Central Electricity Authority regulations governing technical requirements (LVRT, frequency response, reactive power) for utility-scale solar connecting to high-voltage transmission networks.
Which solar projects need CEA Connectivity?
Plants ≥ 5 MW connecting to STU (state transmission) or ≥ 50 MW connecting to CTU (central). Smaller plants use DISCOM net metering instead.
What technical requirements?
Low-voltage ride-through, frequency operating range, reactive power capability, anti-islanding, real-time SCADA reporting.
How long is the CEA connectivity process?
6–18 months including system impact study, transmission availability, augmentation if needed, and commissioning.
