Haldon Solar Farm: Mackenzie Basin

Lodestone Energy (private developer) · Canterbury

A 220MW solar farm on 320 hectares within Haldon Station, a 22,000-hectare property in the Mackenzie Basin, generating about 370GWh a year, enough for roughly 45,000 homes. Cost is put at about $310m and the build at 12 to 16 months. It is the first solar farm approved under the Fast-track Approvals Act, following six months of panel assessment. The Environmental Defence Society has appealed the decision to the High Court, arguing the panel should have declined it and objecting to conditions that leave a technical review panel to judge in ten years whether the required 'no net loss' ecological outcomes were met. No completion date is published and no financial close has been reported, so neither is shown.

Election risk assessment

Privately developed renewable generation, not dependent on a Crown funding decision. The live risk here is legal rather than political: the Environmental Defence Society has appealed the fast-track approval to the High Court.

Government priority alignment

HIGH: Renewable generation and fast-track consenting are both stated government priorities; this is the first solar farm approved under the Act.
