Variability in Solar and Wind generation has emerged as a concern in large-scale adoption of renewables, especially after it contributes a major share in the energy mix. Hybridisation of wind and solar plant is developing a solution which will reduce this variability due to complementary nature of their generation profile - solar generation is higher during the day, while wind generation can be higher in the night.
Hybrid projects would also have much higher capacity utilization, thus removing the intermittency challenge. Such projects also enjoy the additional benefit of a reduction in costs associated with sharing transmission lines. Peak balancing through gas and hydro generation shifting, demand management, smarter grids, electric vehicles as well as storage solutions including battery, pumped hydro and others are expected to further help out in smoothening out the variability cause due to nature of renewable energy supply.
