Developers in Singapore and Johor now face a critical challenge: securing land isn’t the main hurdle—it’s ensuring the site can be powered within the project’s required schedule. Singapore has provisionally set aside 200MW of new data-centre capacity, while Johor has introduced expedited grid-connection processes to address this bottleneck.
These trends highlight a shift in how sites are chosen: the potential of a property now increasingly hinges on what can be linked to it. While a data-centre location might seem promising based on standard property factors like size, zoning, road access, and proximity to fibre, it may still be inadequate when the electrical connection is scrutinized.
Power Availability as a Real Estate Constraint
If a project requires a new substation or transmission upgrade, the challenge goes beyond an engineering task. It can affect the start date of construction, the duration capital is locked up, and when a building can start producing revenue. For investors, the key question is shifting from “Can we acquire this land?” to “When can this land actually be energised?”
Singapore illustrates this constraint. In August 2026, the government provisionally awarded a total of 200MW in new capacity to four data-centre operators as part of its second Data Centre Call for Applications. This initiative was structured around a controlled growth model, evaluating proposals based on their strategic, economic, and sustainability contributions.

Singapore is also planning additional generation capacity for 2031 and 2032 as peak electricity demand is projected to rise from 8.2GW in 2025 to 11.9GW in 2032, with data centres among the energy-intensive sectors contributing to that growth. For property owners and developers, the significance is not simply that Singapore is adding another 200MW.
Grid Connection as a Development Constraint
The critical point is that new data-centre capacity is being allocated alongside decisions regarding the supporting power infrastructure. In a market where land is already scarce, electrical capacity becomes another development hurdle. Two locations might share similar physical traits, but one can be significantly more valuable if its grid connection is already established and timed.
Johor is addressing the same problem by reducing connection timelines. Tenaga Nasional Berhad’s (TNB) Green Lane Pathway aims to cut the standard electricity connection period, which can be 36 to 48 months, down to as little as 12 months. Concurrently, its One-Stop Centre offers a dedicated process for data-centre applications.
As of September 2025, TNB reported 49 data-centre projects in its system, accounting for approximately 7.1GW of maximum demand at various stages. A 150MW project in Johor utilized the Green Lane and One-Stop Centre to expedite its electricity-supply application and implementation schedule.

A faster connection to power can shorten the time a developer holds land and incurs development costs before the asset becomes operational. It can also simplify the management of financing, construction, fit-out, and customer commitment sequences. In essence, the connection timeline can impact the investment viability of a site even before construction begins.
In April, PLN Batam entered into a 511 MVA electricity supply agreement with DayOne for the phased development of data centres at Kabil Industrial Estate. BP Batam emphasized the project’s competitiveness due to the combination of available land, reliable energy, and regulatory certainty.
This is a major development for industrial real estate because it alters what a large-scale estate can provide. The offering is no longer just a plot with roads and basic utilities. For a data-centre user, a dependable way to access large power loads can be a key component of the site’s functional value. India presents the same challenge but on a much broader geographic scale.
Government data shows installed data-centre power capacity rising from about 375MW in 2020 to 1.57GW in August 2026, with nearly 8GW projected by 2030. At a September 2026 industry roundtable, government and industry representatives discussed cluster-based transmission and substation planning, Day-1 sanctioned load and dual power feeders, alongside land and approvals.

The detail matters. Once transmission and substation planning enters the same site-development conversation as land acquisition and approvals, power is no longer something developers can leave until the engineering stage. Industry estimates put India’s modular data-centre market at US$1.19 billion in 2025, rising to US$3.90 billion by 2032.
This growth could change how “development-ready” land is assessed across Asian data-centre corridors. The due-diligence file may need to establish not only land title, zoning, and connectivity, but also available grid capacity, required network works, approvals between the site and the grid, and the credibility of the energisation schedule.
Singapore’s capacity allocation, Johor’s effort to shorten connection times, Batam’s estate-level electricity commitment, and India’s push to plan transmission around future clusters all illustrate how the grid is becoming integral to property decisions.
