The main thing Vector takes into consideration is the condition of the overhead power lines and poles. If they’re in bad shape, they’re probably a good candidate for undergrounding.
Other things they consider are:
- History of faults in the area
- The number of customers who will benefit
- Whether other utility works are planned for the area (Is other digging going to happen anyway, such as for water, gas or communication work?)
The amount of money that Vector spends on undergrounding is controlled by the Trust Deed (our founding document). According to the Deed, the money we receive from Vector as a dividend can’t be spent on extra undergrounding – instead, we pass it straight on to our 308,000 beneficiaries to spend however they want.
