Over the past few years, the government of India has set ambitious targets for wind and solar energy: current targets would see wind and solar capacity grow by 600 percent through 2022, to 60 GW and 100 GW of energy, respectively, from current cumulative installed capacity of about 25 GW. To put those numbers in perspective, 1 GW provides power for 700,000 modern homes; 160 GW would power a sizeable portion of India’s energy needs.
These targets are good for both India’s energy supply and for economic growth – a theme emphasised by US President Barack Obama and Indian Prime Minister Narendra Modi recently in announcing their joint commitment to increasing investment in clean energy and low-carbon economic growth.
However, this task is made difficult by the government’s limited budget, which is constrained by a large fiscal deficit and multiple development priorities.
Further, markets will not provide finance to meet these targets alone. In fact, our analysis shows that the single biggest challenge to scaling up renewable energy is the cost of finance – in particular to debt. Unfavourable debt terms add 24-32 percent to the cost of renewable energy in India, compared to similar projects in the US. Domestic debt is expensive due to unfavourable macroeconomic conditions as well as underdeveloped capital markets, and foreign debt becomes expensive once hedging costs are added.
The good news is that India can address this situation in a way that also saves money for taxpayers, electricity customers, and scales up renewable energy.
