Marsden A was a 250 MW oil-fired power station near the Marsden Point Oil Refinery at Marsden Point, Ruakaka, Northland, New Zealand. It was built between 1964 and 1966 and commissioned in 1967.[1] 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 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reactive power support to Transpower's national grid in Northland,but were decommissioned in 2007 when they were superseded by solid-state power support devices within Transpower's network.
