The landlord is not responsible for paying the tenant's unpaid bills
The landlord has to recover the unpaid Bills from the tenant company by filing a suit
If the bill is unpaid by the user then the electricity supplying company issues a notice to the subscriber to pay the dues and on failure to so pay, the meter is taken away from the premises and then the electricity supplying company has to take legal steps against the subscriber for recovering the unpaid dues with interest and penalty
If there is a separate meter installed at the address of the premises in your name, then the electricity supplying company has no business to terminate the supply for the same
You will have to file a complaint against the electricity supplying company to the higher authority as per the hierarchy of authorities given on the website of the supplying company and after exhausting those remedies you can approach the court if your grievance is not redressed
