The Ministry of Power has proposed to support pumped hydro storage projects with concessional climate finance, utilising sovereign green bonds for mobilising resources for green infrastructure development, which involves renewable energy charging.Furthermore, the ministry has issued an order waiving inter-state transmission system charges for electricity evacuation from new hydropower projects in the country.
