Draft wind-solar hybrid
Nov 30, -0001
Draft National Wind-Solar Hybrid Policy which aims at providing a framework to promote large grid connected wind-solar PV system for optimal and efficient utilisation of transmission infrastructure among others.
India’s wind & solar capacity:
- India has set an ambitious target of reaching 175 GW of installed capacity from renewable energy sources including 100 GW from solar and 60 GW from wind by the year 2022. Various policy initiatives have been taken to achieve this target. The country has already crossed a mark 26.8 GW of wind and 7.6 GW of solar power installed capacity during May 2016.
- Solar and wind power being infirm in nature impose certain challenges on grid security and stability. Studies revealed that solar and winds are almost complementary to each other and hybdridation of two technologies would help in minimizing the variability apart from optimally utilizing the infrastructure including land and transmission system.
- Superimposition of wind and solar resource maps shows that there are large areas where both wind and solar have high to moderate potential.
- The existing wind farms have scope of adding solar PV capacity and similarly there may be wind potential in the vicinity of existing solar PV plant.
- Suitable policy interventions are required not only for new wind-solar hybrid plants but also for encouraging hybridization of existing wind and solar plant.
Objective of Policy
- The main objective of the Policy is to provide a framework for promotion of large grid connected wind-solar PV system for optimal and efficient utilization oftransmission infrastructure and land, reducing the variability in renewable power generation and thus achieving better grid stability.
- Policy aims to encourage new technologies, methods and way-outs involving combined operation of wind and solar PV plants.
- The Goal of the Policy is to reach wind-solar hybrid capacity of 10 GW by 2022.
- This is a step in the right direction for the promotion of renewable energy sector on a larger scale
- While there are inherent advantages in hybrid projects in optimal utilisation of resources, the project economics for such projects (whether for new or hybridisation of existing wind & solar plants) would be critically dependent upon the tariff level which may be either feed-in tariff based or competitively bid based, as is proposed in the policy
- The draft policy is not clear about the financial incentives for hybrid systems and merely refers to the existing incentives for solar and wind projects.
- Achieving the targeted capacity of 10 GW, as mentioned in the draft, would require a firm commitment towards facilitating such systems, from the regulatory as well as financial perspective.
