'''Marsden A''' was a 250&nbsp;MW oil-fired power station near the [[Marsden Point Oil Refinery]] at [[Marsden Point]], [[Ruakaka]], [[Northland Region|Northland]], New Zealand. It was built between 1964 and 1966 and commissioned in 1967.<ref>{{cite web |url= https://natlib.govt.nz/records/22674363 |title=Marsden A Power Station (N.Z.) |publisher=National Library of New Zealand |access-date=12 February 2022}}</ref> It acted as an emergency reserve power station, serving the load centre of Auckland to the south. It was cooled through a long seawater pipe out into [[Bream Bay]], which is now used to supply an [[Aquaculture in New Zealand|aquaculture industry]] nearby.
Following the commissioning of the dual coal- and gas-fired [[Huntly power station]] in 1982, Marsden A became less used, and it was mothballed in the 1990s due to rising oil prices. One of the generators was subsequently run as a [[synchronous condenser]] to provide reactive power support to [[Transpower New Zealand Limited|Transpower]]'s national grid in Northland, but were decommissioned in 2007 when they were superseded by solid-state power support devices within Transpower's network.
