Transitioning away from gas: A case study in Esperance


In late 2021, the local Esperance community were faced with a significant challenge.  Its local gas distribution and retailer was exiting the market. With no viable prospects for a replacement provider, Horizon Power and the WA Government swung into action. What resulted was the electrification of a regional community in 14 months, and during a world-wide pandemic!  Esperance may have been the first, but it won’t be the last community to make this transition. Horizon Power’s Stephanie Unwin will share the successes and lessons learnt from this exciting project.
