The Centre has proposed an outlay of Rs 22,000 crore for power and renewable energy sector for 2020-21, Finance Minister Nirmala Sitharaman said on Saturday.

In her second Budget presentation, the finance minister said the Centre has proposed that discoms should replace conventional meters with smart pre-paid meters and give an option to consumers to choose electricity suppliers.

The finance minister also said the natural gas pipeline grid will be expanded to 27,000 km from over 16,000 km now and further reforms for transparent price discovery for natural gas will be undertaken.
