Trustpower's current development projects in New Zealand include the Awhitu Wind Farm near Waiuku, the Wairau Hydro Scheme near Blenheim and the Kaiwera Downs Wind Farm in Southland.

On 2 November 2008, Trustpower opened Stage 1 of the Snowtown Wind Farm, its first wind farm in Australia. The wind farm is near the township of Snowtown, 170 km north of Adelaide, and will generate 370-380 GWh pa with 47 wind turbines. Project cost is $220 million.[6] The project was completed in November 2014.[7]

The Myponga Wind Farm is a $120m project of 16 wind turbines, located near Sellicks Hill on the southern outskirts of Adelaide. Trustpower received approval for the project in 2002 and it is due to be operational by the end of 2010.[8]
