JOHOR BAHRU \u2013 In Iskandar Puteri\u2019s upscale Eco Botanic enclave, owners are beginning to receive the keys to European-style terraced homes launched three years ago.<\/p>\n
Finance manager Lee Shi Qing bought a 2,293 sq ft terraced unit for around RM1 million (S$313,000) as her first matrimonial home in Johor. But after construction began on a nearby data centre and power transmission towers were erected, she put the property up for sale six months ago.<\/p>\n
\u201cThe land clearing for the data centre started last year, and the new pylons went up this year,\u201d said the 38-year-old, referring to the 64-megawatt hyperscale data centre by TM Nxera, a joint venture involving Telekom Malaysia and Singtel\u2019s digital infrastructure unit Nxera.<\/span><\/a><\/p>\n \u201cI do have some concerns about living close to high-voltage lines, which is part of why I\u2019m selling,\u201d she told The Straits Times.<\/p>\n Johor\u2019s data centre boom is bringing power transmission lines, pylons and industrial facilities closer to residential neighbourhoods<\/span><\/a>, raising concerns over noise, the environment and the resale prospects of nearby homes. In a housing market already grappling with abundant supply, the new infrastructure could make some properties harder to sell, even if fears over health risks are not borne out by scientific evidence.<\/p>\n \u201cIn the residential property market, perception heavily dictates pricing. Even if scientific evidence clears low-frequency electromagnetic fields of immediate danger, the real estate market prices in stigma, visual blight, and sensory disruption,\u201d said Samuel Tan, chief executive of Johor Bahru-based property consultancy Olive Tree Property Consultants. \u201cProperties next to or facing high-voltage pylons can lose a significant share of potential buyers.\u201d<\/p>\n National utility provider Tenaga Nasional, which is responsible for the country\u2019s energy infrastructure, did not respond to The Straits Times\u2019 e-mail queries by press time.<\/p>\n In a statement on Nov 3, TM Nxera said it does not own or operate the power transmission infrastructure in the area.<\/p>\n \u201cHowever, we recognise the importance of working with the relevant parties to help address the concerns raised by the surrounding community,\u201d it said.<\/p>\n It added that the TM Nxera campus is being developed on land designated for this purpose, with the requisite approvals from the relevant authorities and in compliance with the conditions attached to them.<\/p>\n Near the Eco Botanic site in Iskandar Puteri, grey monopole transmission towers line the road. Residents have called them an eyesore.<\/p>\n Lee said only two prospective buyers had made inquiries since she listed her property.<\/p>\n \u201cI think Eco Botanic is really a good place, but the problem with the property is that the market is too saturated,\u201d she said, noting that more landed homes were being built nearby.<\/p>\n Her concerns come amid a property glut in Johor.<\/span><\/a> The state had 4,222 completed homes and 9,946 serviced apartments left unsold in the first half of 2026, the highest numbers in Malaysia, according to the National Property Information Centre, under the Valuation and Property Services Department.<\/p>\n Electric transmission lines running along a row of shophouses at the Eco Botanic estate.<\/p>\n ST PHOTO: HARITH MUSTAFFA<\/p>\n<\/figcaption><\/figure>\n There are 65 data centre projects \u201cin various stages of approval\u201d in Johor, according to Natazha Harris, chief executive of state investment agency Invest Johor. Data centre tracker website Baxtel lists 31 already operational facilities in the state.<\/p>\n Johor has benefited from data centre demand spilling over from Singapore, where land and power constraints led to a moratorium on new data centres from 2019 to 2022. Some of the southern state\u2019s capacity<\/span><\/a> was developed during that period.<\/p>\n Its data centre capacity has grown from 10MW in 2021 to a live IT load of 1,110MW, making it Asia-Pacific\u2019s third-largest market after Tokyo and Singapore, according to Knight Frank\u2019s Data Centre Atlas 2026, released in August.<\/p>\n The rapid expansion has also put pressure on utilities to upgrade infrastructure sooner than planned. \u201cWhen data centres come in, they require huge loads… Utilities like TNB and (Johor water supplier) Ranhill SAJ had their master plans for 2030 or 2035, but because of this influx, they had to compress that timeline and bring those infrastructure upgrades forward to today,\u201d said Natazha.<\/p>\n ST\u2019s checks using Open Infrastructure Map data and Google Earth historical imagery found more than 200 transmission towers around Iskandar Puteri, with about one in five apparently erected since late 2025. But it is not stated how many of these are data centre-related infrastructure.<\/p>\n For residents, the question is whether the new infrastructure will affect not just their surroundings, but also their ability to sell their homes.<\/p>\n Earlier this year, residents of Nusantara Prima and Nusa Bayu townships voiced objections to a data centre development<\/span><\/a> near Persiaran Bayu in Iskandar Puteri, saying construction had caused dust to spread into their homes.<\/p>\n Lim Soon Hai, an Iskandar Puteri municipal councillor, told ST that some residents living near data centres have complained about persistent humming noises and higher-than-usual temperatures, which they believe are linked to cooling-system emissions. \u201cWhen data centres come online, they emit heat from their cooling system and that can cause the environment to become warmer,\u201d he noted.<\/p>\n PropertyGenie data shows median residential property prices of RM452 per sq ft in Nusantara Prima and RM409 in Laman Setia, both located within 500m of the data centre \u2013 compared with RM505 in Nusa Bayu, which is farther from the site. The figures provide a snapshot of prices in the three neighbourhoods, but do not establish that the data centre explains the differences.<\/p>\n Nusantara Prima resident Mohanambal Rethinam, who runs a nearby kindergarten, said enrolment has fallen from 50 in 2025 to 20 in 2026.<\/p>\n \u201cWe surveyed about 20 parents for feedback… and their top concern is the environment. \u2018We are worried about the data centre in front of your school \u2013 your kindergarten is very near to it,\u2019 they say,\u201d she told ST. \u201cIf possible, I\u2019d want to shift out of here. The environment has drastically changed \u2013 it\u2019s warmer, dusty and it just feels very unconducive.\u201d<\/p>\n Another resident considering a move is Nooraini Jaafar, 68, who moved from Singapore to Nusantara Prima with her Singaporean husband 10 years ago. She said the data centre had replaced a once-cherished forested hillside, altering the neighbourhood\u2019s character.<\/p>\n The retiree bought her terraced home for around RM400,000 in 2014 and has been told it could fetch about RM600,000 today. \u201cI had to wait 10 years to see some profit for my house, but I worry people might not be interested in it because they will have to contend with living near the data centre.\u201d<\/p>\n Cafe owner Danish Nordin, 28, who built his D\u2019Mangan Cafe premises beside a row of around a dozen pylons that were erected in late 2025, said contractors had completed cabling works in recent months. \u201cI\u2019m afraid the pylons are too close to my cafe,\u201d he said, expressing concern that they might topple during bad weather.<\/p>\n A power transmission monopole built several metres away beside a cafe in Kampung Ladang in Gelang Patah.<\/p>\n ST PHOTO: HARITH MUSTAFFA<\/p>\n<\/figcaption><\/figure>\n For residents living near transmission lines, the question is whether the electromagnetic fields they produce pose a health risk.<\/p>\n Mohd Fadhil Md Din, Universiti Teknologi Malaysia\u2019s Campus Sustainability Centre director, told ST that transmission lines produce non-ionising, low-frequency electromagnetic fields (EMFs) that fall to normal background levels within 50m to 100m.<\/p>\n \u201cWhere residences are genuinely 200m to 300m away, the scientific evidence would not support a blanket conclusion that residents are experiencing dangerous EMF exposure or that relocation is required on health grounds alone,\u201d the professor said.<\/p>\n Meanwhile, Olive Tree\u2019s Tan called Johor\u2019s rapid development an \u201cirony\u201d: infrastructure meant to boost Iskandar Puteri\u2019s economic value could instead hurt its residential property market.<\/p>\n Burying the connections underground one day could allay residents\u2019 concerns about potential health risks, he said.<\/p>\n \u201cThis is a classic case of paying a \u2018small\u2019 price for rapid development,\u201d he added.<\/p>\n Note:<\/b> This story has been updated to include TM Nxera\u2019s response.<\/p>\n Sign up for our weekly\u00a0Asian Insider Malaysia Edition<\/span><\/a>\u00a0newsletter to make sense of the big stories in Malaysia.<\/p>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n JOHOR BAHRU \u2013 In Iskandar Puteri\u2019s upscale Eco Botanic enclave, owners are beginning to receive the keys to European-style terraced homes launched three years ago….<\/p>\n","protected":false},"author":1,"featured_media":97363,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"","fifu_image_alt":"","footnotes":""},"categories":[2611],"tags":[],"class_list":["post-97362","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-buzz-headlines","wpcat-2611-id"],"_links":{"self":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts\/97362","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=97362"}],"version-history":[{"count":0,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts\/97362\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/media\/97363"}],"wp:attachment":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=97362"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=97362"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=97362"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}<\/picture><\/div>
