Formerly Calcutta Electric Supply Corporation; part of the RP-Sanjiv Goenka Group. Howrah city is in the CESC area, but outer parts of Howrah district are served by WBSEDCL. West Bengal uses a GRO/CGRO system rather than a CGRF.

Complaint not fixed? How to escalate

Every distribution licensee in India must run a Consumer Grievance Redressal Forum, and every state has an Electricity Ombudsman above it. Work up the ladder; keep your complaint number from step one.
