Heat pump industry group raises issues with Gas Industry Company report

The Heat Pump Suppliers Association (HPSA) has responded to Castalia's 'Switching off the gas distribution network: Consumer, network, and emissions impacts' for the Gas Industry Co and its conclusions are similar to those of Rewiring Aotearoa's.

As the group said on Linkedin: "While the HPSA welcomes robust analysis of New Zealand’s energy transition, we believe several assumptions and modelling gaps in this report risk misrepresenting the true consumer and system benefits of electrification. In our open response, we highlight key evidence from EECA and others showing that:

Heat pumps and heat pump water heaters are already delivering major energy efficiency gains for New Zealand households and businesses.

Rooftop solar and home batteries are rapidly changing the cost and resilience profile of electrified homes.

A coordinated transition focused on energy efficiency and electrification will deliver better outcomes for consumers, the grid, and the climate.
