This document discusses solar and wind power integration with the electric grid in India. It notes that solar and wind power are intermittent sources that can cause grid instability due to high fluctuations. However, other renewable sources like small hydro and biomass are more continuous and provide near-flat generation curves. The document also provides data on the increasing installed capacity of renewable energy sources in India from fiscal year 2007 to 2014, with solar photovoltaic capacity growing the most rapidly. It concludes that renewable energy is clean, green, and cheaper.
