The de-merger proposal, announced by Trustpower last week, has been described by a senior energy analyst as a sensible approach with advantages for the company.
The proposal would result in the most significant change for the Bay of Plenty powerco since it came into existence as a listed company after its transformation from the Tauranga Electric Power Board more than two decades ago.
The board plans to spin off its wind power assets, and wind and solar pipeline into a separate listed company, leaving the New Zealand generation and retail assets in a core listed company.
"It looks like a reasonably sensible proposal," said Andrew Harvey-Green, a senior Forsyth Barr equity analyst who specialises in the energy sector.
"There are a couple of advantages. One, they will have a couple of 'pure-play' [solely renewable energy] vehicles so that investors can choose what kind of exposure they want. And the other thing - as we have seen in the marketplace recently - is that pure-play wind producers in Australia have been attracting fairly good multiples. So there is a suggestion Trustpower may be able to unlock a little bit of value by doing this as well."
