- (i) These regulations may be called the Tamil Nadu Electricity Regulatory Commission-Tamil Nadu Electricity Distribution Standards of Performance Regulations, 2004.2. Definitions.
- In these regulations unless the context otherwise requires, -Chapter 2
Distribution Standards of Performance
3. Quality of service.
- Quality of service means providing uninterrupted, reliable electric supply at stipulated voltage and frequency, which will be the end result of its planning, designing of network, operation and service management to ensure stability in supply and prompt compliance of consumers' complaints on metering and billing. The supply with frequent power failure, fuse of calls, voltage fluctuations will not ensure continuity in supply. These factors determine the degree of satisfaction of the consumers.4. Duties of the licensees to supply on request.
- Section 43 of the Act deals with duty to supply and read as below:"43.(1) Every distribution licensee, shall, on an application by the owner or occupier of any premises, give supply of electricity to such premises, within one month after receipt of the application requiring such supply:Provided that where such supply requires extension of distribution mains, or commissioning of new sub-stations, the distribution licensee shall supply the electricity to such premises immediately after such extension or commissioning or within such period as may be specified by the Appropriate Commission:Provided further that in case of a village or hamlet or area wherein no provision for supply of electricity exists, the Appropriate Commission may extend the said period as it may consider necessary for electrification of such village or hamlet or area.| Category | Time Schedule |

- A consumer can utilise a service connection given to him for a purpose different from the purpose for which he originally obtained the service connection, only if the same tariff is applicable to the new purpose also. If a different tariff is applicable to the new purpose, the consumer shall apply to the licensee before changing the purpose and a revised test report will be taken indicating the change in the tariff.The licensee shall effect change of tariff within seven days from the date of receipt of application from the consumer.However, no consumer shall be permitted to change the tariff of the service connection from any low tension tariff (other than agriculture) to low tension tariff for agriculture.10. [ Complaints in Billing, etc. [Substituted by Commission's Notification No.TNERC/SPR/9-1, dated 25.7.2006 (w.e.f. 16.8.2006).]
