Scott Base is aNew ZealandAntarctic research station atPram Point onRoss Island nearMount Erebus in New Zealand'sRoss Dependency territorial claim. It was named in honour of CaptainRobert Falcon Scott,RN, leader of twoBritish expeditions to theRoss Sea area of Antarctica. The base was set up as support to field research and the centre for research intoearth sciences, and now conducts research in many fields, operated byAntarctica New Zealand.
The base is 3 kilometres (1.9 mi) from the larger U.S.McMurdo Station via Willy Field road, the main road toWilliams Field.

Scott Base was originally constructed in support of the UK inspired and privately managedCommonwealth Trans-Antarctic Expedition (TAE). The New Zealand government provided support for the TAE and also for theInternational Geophysical Year (IGY) project of 1957, five of whose members were attached to the Expedition. In February 1956, 10 months before the TAE and IGY parties were due to head to the Antarctic, Frank Ponder, an architect at theMinistry of Works (New Zealand), was given the task of designing the base. Ponder's design consisted of six main buildings and three smaller scientific labs. The main buildings were to be placed at least 7 metres apart because of fire risk but were linked to one another by a covered way of galvanised iron. Three New Zealand observers who were also given the task of selecting the site for a base went toMcMurdo Sound with theUnited States "Operation Deep Freeze I" in the summer of 1955. After evaluating possible sites, a location nearButter Point was chosen. This was later changed toPram Point as it provided better access for offloading supplies from the Expedition ship HMNZSEndeavour and also allowed for the operation of the critical RNZAF Antarctic Flight on a nearby ice runway. The base looks out over what is now known asHaskell Strait. Scott Base passed over toNew Zealand Government ownership via the Department of Scientific and Industrial Research (DSIR), on 5 March 1958, at the conclusion of the TAE.
During the IGY the United States facility at Hut Point did not operate as a scientific base. It was the New Zealand expedition’s responsibility to furnish the important scientific data (auroral, ionospheric, seismic, etc.), linking the McMurdo area research activities with those of the United States Pole Station and the joint United States–New Zealand station atCape Hallett,Victoria Land.
In 1958, following completion of the TAE and IGY, New Zealand made the decision to continue to operate Scott Base for scientific research, much of which depends upon the continuity of recorded data over a period of years. In order to maintain operations, a base rebuilding programme began in 1976. As of 2008, the only original building is the TAE 'A' mess hut, which contains material recording New Zealand's involvement in Antarctica since 1957. In 2005 the two-story high Hillary Field Centre was commissioned, increasing the floor area of Scott Base by 1800 square metres and providing work areas to support field parties as well as additional office space. The building was officially opened by then-Foreign MinisterPhil Goff andSir Edmund Hillary.
The leader of Scott Base for the 1964–65 season,Adrian Hayter, published a personal memoir of his experience.[2] He was preceded as Leader by Russell Rawle[3] and followed by Mike Prebble.[4] These three leaders are commemorated withRawle Glacier,Mount Hayter andPrebble Glacier, assuming the leader in 1965–66 was on the base support party of 1961–62.
From 1957 until 1986, dogs played a part in base operations. Initially, they were an essential means of transport, but with better technology, their importance dwindled until they were removed in line with environmental treaties.
Scientific diving operations began in 1985.[5] Between 1985 and 2006, a total of 1,296 had been logged.[6]

In support of the future of New Zealand’s Antarctic science programme, the base will be redeveloped. In June 2019 the Government committed NZ$18.5 million (US$12.4 million) for the next phase of the Scott Base Redevelopment project, which will see the base's 12 separate buildings replaced by three large interconnected buildings.[7][8] Jasmax andHugh Broughton Architects came up with the architectural design.[9] Since then the New Zealand Government has committed $344 million to rebuild the base.[10]
On 5 November 2021, Antarctica New Zealand confirmed that PrimePort Timaru will host the redevelopment of the prefabricated Scott Base facilities. Besides the three interconnected buildings, the project also involves upgrading theRoss Island wind farm. The redevelopment project will create an estimated 700 jobs over the next six years.[11]
The A Hut of Scott Base is the only existing Commonwealth Trans-Antarctic Expedition (1956–1957) building in Antarctica. It has been designated aHistoric Site or Monument (HSM 75), following a proposal by New Zealand to theAntarctic Treaty Consultative Meeting.[12]
The base is made up of a collection of Chelsea Cucumber green[13] buildings which are linked by all-weather corridors. These buildings can accommodate 86 people over summer,[1] with between 10 and 14 people remaining over the winter.[14]
Like nearbyMcMurdo Station, Scott Base is connected to the global telephone network via a Satellite Earth Station operated bySpark New Zealand, located approximately 3 kilometres (1.9 mi) away at Arrival Heights. Spark NZ also provide phone services to McMurdo for calls to New Zealand as well as to theItalian Programme at Terra Nova Bay. McMurdo Station has an independent communications infrastructure located at Black Island and linked to Ross Island via microwave.[citation needed]
Scott Base is today operated by Antarctica New Zealand.
ThreeEnercon E-33wind turbines (330 kilowatts (440 hp) each) were installed in 2009 to co-power Scott Base and McMurdo Station, reducing diesel consumption by 11%: 463,000 litres (102,000 imp gal; 122,000 US gal) per year.[15][16] Battery failures have reduced power capacity by 66%.[17]
"the small battery component that we have within our grid which we called the power store unfortunately has failed, and that was due to the failure of a non-replaceable part, so that has significantly limited our ability to use our wind turbines to the fullest capacity, so in 2019 we've had to curtail our Wind Farm to about 33% of its full potential"[17]
Three new wind turbines were planned for the 2023-4 season, with great capacity: one new one will be greater then previous three combined. The strong winds make wind power a practical alternative, and the new wind system should supply 90% of the power at Scott Base.
A polar ice cap climate with evenly-distributed precipitation (KöppenEFf) prevails at Scott Base. The base has fairly typical weather conditions for coastal Antarctica, with minimum temperatures around −45 °C (−49 °F) and summer maximum only occasionally above freezing point. It is exposed to the full strength of southerlyblizzards, although overall it is less windy thanMcMurdo Station. The maximum wind velocities experienced have been gusts up to 185 kilometres per hour (115 mph) with steady velocities under blizzard conditions of 95–115 kilometres per hour (59–71 mph). The highest recorded temperature was 6.8 °C (44.2 °F), the coolest −57 °C (−71 °F) and the mean temperature −19.6 °C (−3.3 °F).[18]

Maria Fernando is a Electrical & Wind Engineer at Antarctica New Zealand....In January 2010, the Crater Hill Wind Farm was commissioned and became operational, the world's southernmost wind farm. The three turbines, supply electricity to a shared power microgrid that connects Scott Base to McMurdo Station, called the Ross Island Energy Grid (RIEG). A number of improvements have been made over the lifetime of the RIEG, including automation of the Scott Base generators in order to more efficiently use generated electricity between the two stations when wind generated electricity is not enough to meet the power demands of the Ross Island network. Innovation and collaboration between Antarctica New Zealand and the United States Antarctic Program has made the project successful. Ongoing collaboration occurs to ensure the day-to-day operation of the microgrid and to work through any issues. This presentation will offer an update to the operation of the Crater Hill Wind Farm in the years since construction and the wider Ross Island Energy Grid, highlighting safety and maintenance issues that have occurred, lessons learned and successes achieved through collaboration.
