After months of writing to the Energy Minister (should be Munster), with no result worth mentioning, I sent an email to Ergon on this subject. Only took Ergon 3 weeks to answer, as follows: "In terms of location, the network will run from Cairns to Toowoomba, with individual fast charging sites located approximately every 100km at major regional centres or towns along the way where Ergon Energy has depots. Actual site locations haven’t yet be determined as will involve discussions with stakeholders, such as councils and state government. In terms of timing,first installs are expected to occur in late 2017 and take approximately 12 months to do all the installs we are planning along the route to achieve connectivity. With regards to cost, we can’t provide any information at this stage as we are currently going through a tender process and negotiation with vendors." This is from one of their senior development engineers. I advised him that the cost of the WA electric highway was exhorbitant and this would mitigate against its use by many. I also emphasised that a green source of energy was preferable.
