Responding to developer requests, the state-run NTPC has deferred a 2 GW solar auction by a week, to Tuesday. Madhya Pradesh Urja Vikas Nigam Ltd is another state-owned corporation that has extended its bid submission deadline – for 33 MWp of rooftop solar – from August 9 to August 17, after similar requests.

Owing to a rapid scaling up of solar capacity, Karnataka has overtaken Tamil Nadu to become India’s top state in terms of installed renewable energy capacity. The state installed 5 GW of new PV capacity in 2017-18 alone—according to a report by the US-based Institute for Energy Economics and Financial Analysis (IEEFA).

The projects are to be developed on a build-own-operate basis for an aggregate capacity of 2,500 MW. The eligible bid capacity is 200-500 MW, with a project capacity of at least 50 MW at one project site. The maximum tariff payable to each project developer is fixed at Rs 2.93/kWh for the entire term of 25 years.

India saw 1.8 GW of corporate solar power purchase agreements in place by the end of 2017. There was a rush of installations for PV projects due to open access waivers. The market is expected to contract slightly this year as waivers are rolled back, but there will be sustained market growth through 2023.

Underlining India’s commitment to becoming the global renewable energy leader, Shri Anand Kumar, secretary of the Ministry of New and Renewable Energy, said the country plans 500 GW of capacity by 2030. He also underlined plans to become a solar and storage manufacturing hub; and said the International Solar Alliance needs to widen its membership.

There was incredulity in some quarters as the federal government raised its renewables ambition another 22%, but the stellar performance of the past four years points to the new target being a realizable one.

India’s PV sector is expanding at a serious pace, creating jobs and further securing energy supply for many businesses. Yet, sourcing battery cell technology at the current rate resulted in annual foreign exchange of Rs. 1012 crore creating deficits, that hopefully can be averted in the future.

The Indian Ministry of New and Renewable Energy (MNRE) says the nation will exceed 175 GW of installed renewable energy capacity as plans for bidding for 115 GW of renewable power projects to March 2020 were announced. The target for PV parks has been increased from 20 GW to 40 GW with some 41 parks in 21 states – with aggregate capacity of more than 26 GW – already sanctioned.

India has unveiled a national wind-solar hybrid policy that provides a framework for promotion of large grid connected wind-solar PV systems for optimal and efficient utilization of transmission infrastructure and land, reducing the variability in renewable power generation and thus achieving better grid stability.

The goal of the project, RE 8760 is to show how the storage of renewable energies can make them usable all year round. The generated solar power is stored and converted into hydrogen. It can also be conserved over long periods and used to recharge fuel cell vehicles during the dark winter months.
