Sabah Infrastructure 2026 — Airports, Roads & Ports

Infrastructure Overview

Sabah covers 73,631 km² with a dispersed population of about 3.77 million in 2026 (OpenDOSM population by state, checked 7 October 2026), which is why connectivity dominates every state development plan. Hala Tuju SMJ 2.0, the 2026 to 2030 state plan launched in January 2026, puts roads, ports, digital connectivity and power generation at the front. Under the 13th Malaysia Plan, Sabah has an approved allocation ceiling of RM12.024 billion covering 1,173 projects across every sector, not infrastructure alone.

The constraints are the familiar ones: mountains, rivers and scattered settlements; a climate that degrades road surfaces quickly; and delivery capacity. The Pan Borneo Highway is the clearest illustration — a project whose completion date has moved from 2029 to the end of 2030 within a single year.

Airports & Air Connectivity

Sabah has five airports, but only four carry scheduled flights. Kudat has recorded no scheduled passenger traffic since 2020, and the Semporna STOLport none either. Kota Kinabalu is the international gateway; Tawau, Sandakan and Lahad Datu serve domestic routes.

Kota Kinabalu carries about 72% of Sabah air traffic, not the 90% widely repeated. On 2023 movements it handled 7.04 million against a Sabah total of 9.80 million. Tawau alone handled 1.71 million, about 1.75 times the 0.98 million a 90% share would leave for every other airport in the state combined.

Kota Kinabalu was Malaysia’s second-busiest airport in 2023, ahead of Penang by under 4%. The terminal is rated at 9 million passengers a year, and MAHB planned interim works to raise that to 10 million — so it has been operating close to its ceiling. A Terminal 1 upgrade to 12 million was approved by Cabinet in November 2024 at RM442.3 million, later described in Parliament as nearly RM500 million. As at July 2026 the work had not started: the Deputy Transport Minister told the Dewan Rakyat that the project awaits a Sabah government decision on the site.

Ports & Maritime

Sabah Ports operates eight ports, of which three handle containers. The main one is the Sapangar Bay Container Port near Kota Kinabalu, run since September 2024 by DPW Sabah, a joint venture between DP World and Sabah Ports. In 2025 it handled 396,694 TEUs against a current capacity of about 500,000 TEU. A federally funded expansion is raising that towards 1.25 million TEU, now expected in October 2027 (62.75% complete in June 2026, Bernama). Sapangar Bay is designed as a regional transhipment hub for BIMP-EAGA trade.

Sandakan and Tawau also handle containers — 56,210 and 83,285 TEUs respectively in 2024 — alongside regional cargo, timber and palm oil exports. Cruise traffic across Sabah in 2025 was 23 ship calls carrying 24,634 passengers, mostly at Kota Kinabalu with four calls at Sandakan.

Roads & Pan Borneo Highway

Sabah had 21,650.7 km of road at the end of 2020 (22,216.5 km in 2018 and 21,425.9 km in 2019), according to JKR's road database as published by DOSM (DOSM Census 2020 Sabah, Table 123). We have not found a more recent official total.

The Pan Borneo Highway is the largest road project in the state’s history. Phase 1 runs 706 km from Sindumin on the Sarawak border to Tawau, in 35 work packages, at a construction cost of RM24.889 billion — with a further RM2.53 billion spent on land acquisition. It is toll-free and fully federally funded.

The completion date has moved repeatedly. Phase 1A was to finish in October 2026, then the first quarter of 2027, and in July 2026 the Deputy Works Minister told the Dewan Negara it is now expected in mid-2028. Both phases together are now targeted for the fourth quarter of 2030. Nine more Phase 1A packages were due to open by the end of 2026. Phase 2 (about 98 km, Tamparuli to Ranau) and Phase 3 (about 432 km, Kimanis to Keningau to Kalabakan to Tawau) remain at planning stage, dependent on future federal approval.

Digital Infrastructure & Connectivity

As at 28 February 2026, internet coverage reached 98.71% of Sabah’s populated areas, up from 73.41% before JENDELA (Nabalu News, 29 April 2026). 5G reached 68.9% of populated areas as at 31 May 2026 (Bernama, 23 July 2026) — the same 68.9% reported in September 2024, when the national figure was 81.9% (Daily Express, 18 September 2024). So Sabah's 5G coverage has been flat for about two years. The 5G measure counts coverage delivered by Digital Nasional Berhad. A second network, U Mobile, reached 63.9% of Sabah’s populated areas by May 2026, and no combined any-network figure is published.

The JENDELA phase 2 programme covers 2,700 sites nationwide; the first 1,000, being tendered in 2026, are in Sabah and Sarawak (Bernama, 29 August 2026).

Power & Water Infrastructure

Electricity: Sabah had a dependable generation capacity of about 1,179 MW against a record peak demand of 1,003 MW in 2021, a reserve margin of roughly 17.6% — thin by planning standards, which is why capacity additions dominate state energy policy. Most generation is owned by independent power producers rather than by Sabah Electricity itself.

Recent additions have landed: the Lahad Datu battery storage facility (100 MW output, 400 MWh capacity) was inaugurated in December 2025 and is the largest in Southeast Asia by energy capacity, though not by output. A 100 MW interim gas plant at Kimanis was due for completion in October 2025 (Borneo Post, 12 August 2025). About 100 MW of solar has been awarded on the east coast (Energy Commission of Sabah), with large-scale solar in Sabah expected to pass 350 MW by 2027 (Utusan Borneo, 12 December 2025). The Sarawak interconnection began supplying Sabah in December 2025 and now carries up to 50 MW (Sarawak Energy). For the state’s power targets to 2035 and progress on each project, see Sabah’s power plan explained.

Rural electrification stood at 96% in 2025 (Energy Commission of Sabah, June 2025), with full rural coverage targeted by the end of 2030. The state energy plan, SE-RAMP 2040, gave 98.3% for 2021. A fall is unlikely; the two figures probably use different definitions or coverage bases, and neither document explains the method. We show both until one is reconciled.

Water: Sabah has 89 water treatment plants with a design capacity of 1,534 million litres a day and production of about 1,420 MLD, and is targeting 90% treated-water coverage in rural areas by 2035 (Bernama, 10 July 2024). The distribution network is about 16,244 km (Daily Express, 3 May 2026).
