Substation Location Visits

Hobson Street Substation (B5 / AORC)

Transpower, in conjunction with local electricity distributor and infrastructure company Vector, redeveloped Hobson Street Substation in 2012 to reinforce power supply to the Auckland CBD.

Hobson Street Substation is connected to the 220 kV (NAaN) cable circuit between Penrose (to the South) and Wairau Road (to the North), supplying power through Auckland and to North Auckland.

The 220 kV equipment is all GIS (Gas Insulated Switchgear) with a 220/110 kV, 250MVA transformer (T12) that connects to Vector’s 110kV subtransmission system. You will have a chance to see both the Transmission and Distribution side of Hobson Street Substation during the tour.

Henderson Substation (B5 / AORC)

Henderson substation is split into two main switchyards, one for the 220 kV equipment and one for the 110 kV equipment. Following a recent outdoor-to-indoor conversion (ODID), the 33 kV switchgear is contained within an indoor building. There are four transformers, two 220/110/11 kV and two 220/33 kV transformers.

The site also has several historical buildings no longer operational and a transformer refurbishment workshop is extensively used by Service providers. The protection panels are in two areas of a traditional control room.

Glen Innes Substation (AC)

This substation consists of a Battery Energy Storage System (BESS) which is one of the largest grid-connected Tesla Powerpack in the southern hemisphere. The facility includes 24 Tesla Powerpacks totalling 1 MW/ 2.3 MWh at the Glen Innes substation, originally installed in 1954. Equivalent to powering 450 average homes for 2.3 hours – the BESS allows Vector to continue to provide a secure, reliable power supply and, in addition, the technology is modular and movable, meaning it can be relocated to other sites if required.
