Energy Transition

First Renewables

First Renewables, part of Clarus, is a business leading the renewable gas work programme. We aim to provide New Zealand homes, businesses and energy-intensive industries with lower emissions gas energy options in the future.

First Renewables is on a mission to accelerate the transition to renewable energy by leveraging the expertise and assets of Firstgas, Rockgas, Firstlight Network and Flexgas. A great example of this is the development of New Zealand's first utility-scale biogas to pipeline project that will deliver renewable gas to customers in the region via Firstgas’ transmission pipeline network.

Innovative technology

Investigating innovative technology is part of Aotearoa New Zealand's journey to cutting emissions, and we firmly believe that the sustainability, reliability and affordability of energy will help get us get there.

Partnering with Powering Change - for the future of Aotearoa New Zealand

The energy sector will play a key role in helping to reduce emissions which is why New Zealand energy companies, including Clarus, have teamed up to create Powering Change, a collective commitment to a more sustainable future for Aotearoa New Zealand.

Powering Change means continuing to make existing energy systems smarter and transforming them to be built around all customers. It means finding better ways to generate, store and use energy, and unlock the potential of technology to get more out of the current energy infrastructure.
