Read the given passage and answer the question that follow.
Prime Minister Modi has recently declared Modhera, Gujarat as India's first 24x7 solar-powered village. It is an important marker in India's ambitious renewable energy vision. The aim is to increase installed capacity by more than three-fold to 500 GW by 2030. The commercial viability of solar power will have a say in realising this goal. Presently, India's electricity sector displays a dichotomy, representing the challenges facing the renewable sector.
Thermal power contributed 75%-85% of the power generated over the last three financial years. Its installed capacity, however, dipped from 62.3% to 59.6% over the same period. During the same phase, solar power installed capacity increased from 9.4% to 12.8% among renewables, its share in a generation increased. Therefore, among available sources of renewable energy, it's solar power that holds the brightest promise. Renewable energy consumption gets a big push from the Government of India in the form of legally binding purchases called Renewable Purchase Obligation (RPO). Despite this boost, renewables struggle to meet generation targets because states which have an incentive to keep costs low often fail to meet their RPO. A March 2021 parliamentary committee report showed that only four states met their entire RPO target in 2019-20.
Solar power trajectory is delicately poised despite the Government's move to increase the share of RPO till 2030. An increase in important tariff this year on inputs such as solar modules to boost domestic industry will in the near future push up project costs and, thereby, power tariffs. This is at odds with a separate move to nudge discoms to maintain financial discipline. Moreover, the renewable space itself is set to get more competitive with the advent of green hydrogen. The renewable energy is set for a churn with a complex set of factors at play.
