In contrast to last year's first auction to buy solar output, when other power technologies were also contracted, this year the government will only tender for utility-scale PV projects with at least 5MW of capacity.

Developers have to register projects for the auction by 14 April and the plants contracted will have to be built by 1 August 2017.
