According to a PwC report titled 'Hydropower in India - Key enablers for a better tomorrow', the sector is facing several challenges, including financing, inadequate enabling infrastructure and regulatory hurdles.
"Ministries, departments and State Governments need to work together collaboratively and efficiently, in a co-ordinated way, to achieve policy goals and capacity addition targets. Alignment of processes, structures and institutional framework is necessary to achieve this," it said.
The report said a large number of hydropower projects with common river systems between adjoining states are held up due to a lack of inter-state agreements and disputes on water- sharing.
To achieve the target, the Central government also needs to consider making it mandatory for power distribution utilities to purchase a fixed amount of hydropower, PwC said.

"Such hydropower purchase obligations provide assurance to developers by guaranteeing the purchase of electricity and make projects much more bankable."
Favourable tax treatment, especially at the early stage of projects, will reduce project cost and help secure cheaper financing, the consultant said.
"Initiatives such as India Infrastructure Finance Company have been taken. The Government needs to encourage suitable innovative products like tax-exempt bonds focussed on the hydropower sector.
"Multi-lateral institutions and green funds have in recent times shown some appetite to fund both public and private sector hydropower investments and can be a good source for investors if a sound business case and risk mitigation mechanism can be demonstrated," the report said.
