Application Fees for Connecting a Solar Power System to the Grid in New Zealand

Application Fees for Connecting a Solar Power System to the Grid in New Zealand

One of the additional costs you might have to pay when installing a grid-connect solar power system is a fee to your local lines company to approve your solar power system exporting power to the grid.  Not all lines companies have a charge, lucky for some!  Some lines companies will also charge you an observation and testing fee.

Normally your selected solar installation company will fill in the lines companies application forms and will charge the fee to you, rather than you paying the lines company.

I have been through all of the New Zealand lines companies websites and given some of them a call to find out if they have connection fees and whats the price.  Please note the fees are for solar power system sizes 10kW or less.

Hi Dave, sounds like you now have more than 10kW of solar installed? Therefore the $500 fee sounds right according to Vector. Hopefully no more extortion to come!

Hi Barney

The fees in this blog are one off payments.

Unison are the only company that are charging the solar tax, which is an annual fee that will effect solar power owners, the extra charge will be between $128 and $258 a year. Unison defend their solar tax as they say solar power system owners are still heavy users of peak electricity demand. This charge doesn't account for solar owners who have low demand at peak times and does not encourage anyone to reduce their peak demand if they can.

are these application and observation and testing fees, a one-off charge or are they trying it on by charging it as monthly or annual fee.

if so maybe it is time that Parliament stood up to these companies who are not supporting energy saving and removed their ability to make such charges.
