Is New Zealand ready for the scale of electrification it's going to need in the future? And what will it cost us to get there?
Kathryn's guest this morning is the former chief executive of the Electricity Networks Association, which represents all 27 lines companies that operate the poles and wires bringing power to homes and businesses across the country.
Graeme Peters left last month after eight years in the role, but his departing comment that households will be paying twice as much as they do now for electricity within five years generated some headlines.
More sectors, like transport, are going electric - and that's going to require more investment in electricity generation and distribution - with a corresponding increase in charges.
Graeme joins Kathryn to talk about the implications.
