Even as solar and wind are going to be the major source of power going ahead, hydropower plants will continue to remain relevant. “In fact hydro power plants will become more relevant than before as we shift from fossil fuels to renewable resources for power generation. As the quantum of power from wind and solar increases, we will need to ensure corresponding increase in hydro power as well,” said Ajay Sharma, chairman, Forum of the Hydro Power Producers, at the workshop held in Shimla on ‘System Inertia and Flexibility Services from Hydro Stations in Indian Power System’.
