This 2000 MW power will be added after commissioning two 1,000 MW units of the Kudankulam Atomic Power Project.
The target was set at a meeting convened by the Prime Minister to speed up pending projects in the infrastructure sector.
The government looks forward to a capacity addition of 18,000 MW in the power sector.
The two units at Kundankulam are in an advanced stage of completion.
The project has been delayed due to protests over safety and concerns over its impact on the environment.
The first unit of the Kundankulam project is expected to be commissioned by August.
