Tata Power-DDL strives for having absolutely no grievance/complaints from its business associates. Still, if you have one, we have developed a portal where you can submit your grievance. This is a part of the e-portal and hence you will require the same login id and password as that of e-portal. Clicking on this link will take you to the e-portal page where you can log in and submit your grievance.
