Ka mamao waena:210mm
ʻAno kaʻa lima
Mekani hana puna lua
Wahi kūpono: (i nā wahi e pono ai ka hana pinepine)
1.ka mana uila a me ka pale ma ka ʻoihana.
2. ʻoihana mining.
3. nā mea kanu mana.
4.substations.
Hiki ke hoʻopaʻa ʻia i loko o kahi keʻena hoʻololi a hoʻokomo ʻia ma ke kaʻa lima.
Paʻa ka hana a me ka hoʻokomo maʻalahi.
