Under the RPO, distribution companies (discoms) are required to have certain proportion of clean energy supplies. The proportion is fixed by state power regulators. The discoms can also buy renewable energy certificates in lieu of mandated clean energy supplies, from the developers or renewable power generators. Oceans cover 70 per cent of the earth’s surface and represent an enormous amount of energy in the form of wave, tidal, marine current and thermal gradient.
