Contact Energy (Contact) and Microsoft signed a 10-year renewable attribute purchase agreement in September 2022 that is supporting the development of new renewable energy capacity in Aotearoa New Zealand, in line with Microsoft's sustainability commitments. The arrangement will see Contact provide Microsoft with all the renewable energy attributes generated by Contact's new 51.4MW Te Huka Unit 3 geothermal power station. Ownership of renewable energy attributes is the global standard for electricity customers to show they are using a renewable source.

This is important for encouraging renewable electricity, since electricity consumed on a shared grid cannot be traced back to a specific power station. This contract supported Contact's investment decision to begin construction of the new renewable electricity generation facility at Te Huka.
