CONCEPT

Clause (47)of Section 2 of Act, 2003 defines the OpenAccess as

Non-discriminatory provisionfor use of transmission lines

or distribution system or associated facilities with such

lines or system by any licensee or consumer or a person

engaged in generation in accordance with the regulations

specified by the Appropriate Commission

2. A person setting up a captive generating plant carry

power from his captive generating facility to the

destination of his use without payment of surcharge.DISTRIBUTION

3. Any consumer can access a trader, generator,

distribution licensee other than his own distribution

licensee when the State Commission allows him open

access under Section 42(2) of the Act, on payment of

wheeling charge and surcharge to take care of current

level of cross subsidy and or additional surcharge under

Section 42(4), as the case may be.Thus the consumer is

empowered to select his preferred source of supply of

electricity.


5/38

As per Clause 42(4) of the Electricity Act where the State

Commission permits a consumer or class of consumers to

receive supply of electricity from a person other than the

distribution licensee of the area of supply, such consumer shall

be liable to pay an additional surcharge on the charges of

wheeling as may be specified by the State Commission to

meet the fixed cost of such distribution licensee arising out of

his obligation to supply.
