The Electricity Act, 2003

What it does

The Electricity Act, 2003 is the main statute for the power sector. It covers generating electricity, carrying it over transmission lines, distributing it to consumers, trading in it and the rules on its use. Its design is to separate those functions, to open generation to competition, and to put the fixing of tariffs and the issue of licences in the hands of regulatory commissions that sit apart from the government.

Generation does not need a licence under the Act, apart from the approvals the Act and other laws separately require. Transmission, distribution and trading do need one. The Central Electricity Regulatory Commission and the State commissions fix or approve tariffs, settle disputes between licensees and generators, and issue the codes under which the grid runs. An Appellate Tribunal for Electricity hears appeals from them.

Who it binds

It binds generators, transmission and distribution licensees, traders, the grid and load despatch institutions, large consumers who seek open access, and the regulators themselves. State governments and their utilities are bound as well, since distribution is largely a State function carried out under licence or by State utilities. A consumer is bound only in a limited sense, by the rules on theft of electricity and on conditions of supply.

What moved out of it

The Act replaced the Indian Electricity Act, 1910, the Electricity (Supply) Act, 1948 and the Electricity Regulatory Commissions Act, 1998. A judgment decided under one of those must be read with care, because the 2003 Act moved the sector from state-run supply to licensed, regulated supply.

Nuclear power sits partly outside its tariff design. On the site's reading of the SHANTI Act, 2025, which is not yet in force, the Central Government fixes the tariff for electricity from nuclear plants under that Act, notwithstanding the Electricity Act, 2003. That would take the price of one source of power out of the regulator's hands.

What has changed, and when

• The Act was passed in 2003 and replaced the three older laws.
• It was amended later, including by the Electricity (Amendment) Act, 2007. Rules and regulations made under it, by the Central Government and by the regulatory commissions, have changed the working of the sector more often than the Act itself.
• The SHANTI Act, 2025 will, once it commences, set the nuclear tariff by its own provision. As at 28 October 2026 it has not commenced.

What turns on it in practice

For a developer, the first question is what approval each stage needs. Generation may be set up without a licence, but a project still needs a grid connection, a power purchase arrangement, a tariff that the commission has approved or adopted through competitive bidding, and the clearances under other laws. The Act provides that a tariff discovered by a transparent bidding process under central guidelines is adopted by the commission.

For a buyer or a trader, open access and the charges that go with it decide whether a supply is workable. For a lender, the stability of the tariff and the payment record of the distribution utility, which is usually the offtaker, decide whether a project can be financed.

For a nuclear project, the question is how the Electricity Act and the new Act will fit together. The site's note on the SHANTI Act names the Electricity Act as one of the instruments it meets, and a project agreement that depends on the tariff should say which regime fixes it and who bears the risk of the other arrangement applying.
