Industry: Electricity Distribution
Jurisdiction: India (Mumbai, Delhi, Odisha Regional Operations)
Primary Regulator: State Electricity Regulatory Commissions (MERC, DERC, OERC)
Important Safety Warning: Beware of the massive “Disconnection SMS Scam.” Scammers frequently send SMS or WhatsApp messages stating: “Dear Consumer, your electricity power will be disconnected tonight at 9:30 PM because your previous month’s bill was not updated. Please call our officer immediately.” This is a scam. Authentic Tata Power staff will never send alerts from a personal 10-digit mobile number, nor will they ask you to download screen-sharing apps or pay via personal UPI links.
Level 1: Customer Support (Initial Complaint)
- How to complain: Do not use generic national emails. You must register your complaint (billing errors, outages, meter faults) directly with your regional Tata Power distributor’s Customer Care Centre.
- For Mumbai: Call 19124 / 1800-209-5161 or email customercare@tatapower.com.
- For Delhi (TPDDL): Call 19124 / 1800-208-9124 or email customercare@tatapower-ddl.com.
- For Odisha: Call 1912 or 1800-345-7122.
- Availability: The toll-free IVR and emergency outage reporting operate 24x7.
- Timeline: Standard service requests must be acknowledged within 3 working days (for supply/disconnection issues) and 15 working days for all other complaints.

Level 2: Internal Grievance Redressal Cell (IGRC)
- Who to contact: If your Level 1 ticket is closed without a fix, you cannot jump straight to the regulator. You must formally escalate to the Internal Grievance Redressal Cell (IGRC) of your specific region. For example, in Delhi, you escalate to the TPDDL IGRC at icgrc@tatapower-ddl.com. In Mumbai, you escalate to the regional Tata Power IGRC.
- Timeline: Under SERC Regulations, the IGRC must provide a formal remedy to your complaint within a maximum of 30 to 60 days (depending on the state) from the date of filing.

Level 3: Consumer Grievance Redressal Forum (CGRF)
- Authority: If the IGRC rejects your claim, or if the statutory time passes without a resolution, you must file a formal petition with the Consumer Grievance Redressal Forum (CGRF). The CGRF is an independent quasi-judicial body set up specifically to hear consumer electricity disputes against your regional Tata Power licensee.
- Portal/Contact: You must submit your grievance in writing or via the regional web portal to your specific CGRF office. For example, the Mumbai CGRF is located at the Dharavi Receiving Station, Matunga. The Delhi CGRF is located in Model Town.
- Timeline: The CGRF is legally mandated to decide the grievance within 2 months from the date of receipt.

Level 4: Electricity Ombudsman (Final Statutory Appeal)
- Pre-Litigation: Do not use the e-Jagriti consumer court portal or the National Consumer Helpline for electricity disputes. The Electricity Act of 2003 supersedes standard consumer courts.
- Court/Arbitration: If you are aggrieved by the order of the CGRF, or if they fail to issue an order within 2 months, you must file a representation to the Electricity Ombudsman appointed by your State Electricity Regulatory Commission (e.g., MERC for Mumbai, DERC for Delhi, OERC for Odisha).
- Timeline: You must file the appeal to the Ombudsman within 30 to 60 days (depending on the state) from the date of the CGRF order.
