But solar energy is not reliable it can generate electricity only in sun it can’t generate electricity at night time and Storing electricity is costly so focus should be on nuclear power Solar energy should be used to power households in remote areas , heavy industries and railways will depend on Nuclear power plants for electricity
yes, what you say is correct.
But since majority of the solar electricity production happens during the day, and electric consumption is mostly during the day.
say national grid wants to buy 100 units of electricity. New Coal power plant unit usually costs around say 3.5 Rs , that's 350 Rs for 100 units . Solar at the same time cost at an average of 2.36Rs per unit, That's 236 Rs per 100 units, power from old hydel power costs even less.
So the Grid instead buys a mix of solar and coal, while using coal as the base load to maintain grid stability, and using solar to bring down the energy costs.
as far as fluctuations from solar energy are concerned, since ours is a national grid, these fluctuations are handled at the grid level.
The installed Renewable energy capacity of 84.39 Gw includes 37.28 GW from wind energy, 32.52 GW from solar, 9.94 GW from bio-power and 4.65 GW from small hydro plants. At present 31.68 GW capacity projects are at various stages of implementation and 18.68 GW capacity projects are under various stages of bidding.
MNRE: The government has set a target of installing 175 GW of renewable energy capacity by 2022, which includes 100 GW from solar, 60 GW from wind, 10 GW from biomass and 5 GW from small hydropower projects
