'''Haywards''' is a small hillside suburb in the [[Hutt Valley]] near [[Wellington]], New Zealand. It is notable for its large [[electrical substation]], which is the main switching point for the Wellington region, and the home of the North Island converter station for the [[HVDC Inter-Island]], which links the North and South Island electricity networks together.

==History==
Haywards railway station was opened on 15 December 1875, along with [[Belmont railway station, New Zealand|Belmont railway station]]. It was closed in 1954 and replaced by [[Manor Park railway station, New Zealand|Manor Park railway station]].<ref>Hoy, D.G. ''Rails out of the Capital'' pp. 15, 94 (Note A) ([[NZRLS]], 1970)</ref>

Haywards was listed in the 1881 New Zealand census as being part of both Mungaroa Riding and Epuni Riding, with a combined population of 58.<ref>{{cite web |url= https://www3.stats.govt.nz/historic_publications/1881-census/1881-results-census.html|title=Census of New Zealand 1881|publisher= Statistics New Zealand |date= March 2012 |accessdate= 18 April 2018}}</ref>

==Transport==
[[State Highway 58 (New Zealand)|State Highway 58]] is the primary route from the [[Hutt Valley]] to [[Pāuatahanui]] and [[Porirua]]. It leaves [[New Zealand State Highway 2|State Highway 2]] at Haywards. This highway was first built during the 1870s.<ref>W. B. Healy, "Pauatahanui Inlet - an environmental study", New Zealand Department of Scientific and Industrial Research, 1980. ISSN 0077-9636</ref> From the 1940s to the 1970s there were proposals for a railway line, the [[Haywards–Plimmerton Line]], via this route.

In June 2010, the results of a road assessment programme indicated that the Haywards Hill road was amongst the worst in the Wellington region, scoring only 2 out a possible 5.<ref name="uhl-worst">{{Cite news |title=Haywards Hill Road region's worst |last=McLennan |first=Rosemary |newspaper=Upper Hutt Leader |date=30 June 2010 |access-date=21 April 2021 |url= http://www.stuff.co.nz/dominion-post/news/local-papers/upper-hutt-leader/3866079/Haywards-Hill-Road-regions-worst }}</ref>
Construction of a new elevated interchange at the intersection of SH2 and SH58 at Haywards began in 2015 including a new carpark and footbridge across SH2 to [[Manor Park, New Zealand|Manor Park]], and was completed in 2017.<ref name="dp-fasttrack">{{cite news|url= http://www.stuff.co.nz/dominion-post/67361209/Fast-track-for-new-42m-interchange |title=Fast track for new $42m interchange |first=Michael|last=Forbes|newspaper=[[The Dominion Post (Wellington)|The Dominion Post]] |date=14 March 2015 |access-date=21 April 2021 }}</ref> Further safety improvements to SH58 are under construction and estimated to be complete by 2023. These include building median and road-side safety barriers, roundabouts at dangerous road intersections and widening parts of the road to four lanes.<ref name="stuf_Safe">{{Cite web |title=Safety upgrades for SH58, Wellington's most dangerous road |last=Fallon |first=Virginia |work=[[Stuff (website)|Stuff]] |date=29 January 2020 |access-date=21 April 2021 |url= https://www.stuff.co.nz/motoring/119120551/safety-upgrades-for-sh58-wellingtons-most-dangerous-road }}</ref>

==Electrical substation and HVDC converter plant==
The Haywards electrical substation is one of national grid operator [[Transpower New Zealand Limited|Transpower's]] largest substations and is a key part of New Zealand's [[National Grid (New Zealand)|national electricity network]]. The North Island converter station for the [[HVDC Inter-Island]] link is co-sited with the main HVAC substation, and converts the ±350&nbsp;kV direct current electricity transmitted from the South Island converter station at [[Benmore Dam|Benmore]] to 220&nbsp;kV alternating current for the North Island, and vice versa.

220&nbsp;kV to 110&nbsp;kV interconnecting transformers at Haywards supply the regional 110&nbsp;kV network that serves much of the [[Wellington Region]]. Supply transformers at Haywards step down voltage to 33&nbsp;kV and 11&nbsp;kV and provide a connection to the [[Wellington Electricity]] subtransmission and distribution network serving the central-north Hutt Valley, from [[Trentham, New Zealand|Trentham]] in the north to [[Taitā, New Zealand|Taita]] in the south. 220&nbsp;kV lines connect Haywards to the [[Wilton, New Zealand|Wilton]] substation to supply central Wellington City, and north to [[Bunnythorpe]] near Palmerston North to connect with the rest of the North Island grid.<ref>{{cite web|url=https://www.transpower.co.nz/sites/default/files/publications/resources/Transmission%20Planning%20Report%202019.pdf |publisher=Transpower| date= December 2019| title= 2019 Transmission Planning Report|archive-url=https://web.archive.org/web/20200622070825/https://www.transpower.co.nz/sites/default/files/publications/resources/Transmission%20Planning%20Report%202019.pdf |archive-date=22 June 2020}}</ref>
