New Delhi, June 22 (TIWN): Large developers in the renewable energy sector have enough options to boost returns even as challenges mount and will fight aggressively in the various auctions scheduled in 2022, a new report by the Institute for Energy Economics and Financial Analysis (IEEFA) said on Wednesday.

Falling costs of solar modules, which in turn brought down tariffs, fuelled the growth of India's renewable energy growth story.

However, turmoil in global supply chains caused by the Covid-19 pandemic and the Russia-Ukraine war has pushed up costs. Further, renewable energy developers face higher financing costs as surging inflation has forced central banks to tighten monetary policy, pushing up interest rates.
