HECO said the cost to put the power lines overhead is $6.7 million. Underground, it will cost $25 million. https://lnkd.in/gpHDwbKV
But, what is total the cost of ownership of these overhead lines compared to underground for the life of the asset? How much will vegetation management really cost 20 years from now? Some utilities are asking this legitimate question (and others) as they decide to undergound more electric distribution (and transmission) across America.
The Hawaiian neighbors have excellent points of concern. They meet with the developers and HECO on Monday. Stay tuned.
