By having an aim to improve renewable power generation, the government announced a national wind-solar hybrid policy, which seeks to market new projects in addition to hybridization of the present ones.
The government has set an ambitious target of achieving 175 gigawatts (GW) of installed capacity from renewable energy sources by 2022, including 100 GW of solar power and 60 GW of wind power capacity.
The policy offers up an extensive framework to market large grid-connected wind-solar photovoltaic (PV) hybrid system for optional and efficient utilization of transmission infrastructure and land, thereby reducing the variability in renewable power generation and achieving better grid stability.
Besides, the policy also aims to encourage new technologies involving the combined operation of wind and solar PV plants.
Solar and wind power being variable in nature pose certain challenges on grid security and stability and therefore suitable policy interventions are needed not merely for new hybrid wind-solar power plants but in addition for encouraging hybridization of existing plants.
The policy offers up procurement of power from a cross-project on tariff-based transparent bidding process as a result government entities may invite bids.
In addition, it permits the use of battery storage in hybrid projects for optimizing output and further reduce variability.
The policy also mandates the regulatory authorities to formulate necessary standards and regulations for wind-solar hybrid systems.
Beneath the policy, the government will extend all fiscal and financial incentives offered to the wind and solar powered energy projects to convert them to revolutionized hybrid projects. It may also support technology development projects in the field.
On the technology front, the policy offers up the integration of both the vitality sources, wind and solar, at AC as well as DC levels.
