The Clean Energy Regulator has upgraded its estimate of large-scale wind and solar power capacity likely to come into the system this year as momentum picks up towards 2030 climate targets, despite a poor quarter for renewable generation.

The upward revision of almost 30 per cent in expected approvals of large wind and solar farms to between 3 and 4 gigawatts comes after a drop in the contribution from renewables in the June quarter amid a wind “drought” and dry weather in Tasmania.
