Malaysia is moving towards telling its data centres how to behave on the grid, and backup generators are part of it. On 28 October the Deputy Prime Minister told the Dewan Rakyat, the lower house of parliament, that the government requires the sector to source at least 30% of its energy from renewables. In the same answer he said data centres should have backup generators that can be used for demand control, to ease the strain on the grid at critical moments or when operating reserves are low.
What is decided and what is still a draft
The 30% requirement is stated as government policy. The detail is not yet written: the Energy Commission is drafting a framework and guidelines on self-generation and renewable energy use for data centres. The statement encourages operators to build solar for their own consumption so that other electricity users do not carry higher supply costs, and to join the Corporate Renewable Energy Supply Scheme, which lets them buy green power directly.
The reports of the answer do not say how many hours a year the generators might be called on, who would call them, or what emissions limits would apply during that use. Those are the points the guidelines will have to settle.
Why the grid operator wants a say
Every supply application from a data centre is reviewed by the Energy Focus Group and then goes to the Data Centre Task Force. The review looks at grid capacity, the transmission and distribution networks and the investment needed. The numbers in the answer show why: as of August 2026, contracted data centre demand was 2,346 MW, while actual consumption was 1,374 MW, or 58.5% of the contracted figure. The government puts the gap down to the estimates in supply applications not matching what the buildings actually draw.
Nuclear power is still under consideration as a source, but the statement says the preparatory work, from international agreements to safety regulation and trained staff, has to come first.
Standby sets that also run for the grid
A generator that exists for outages runs a few hours a year. One that can be called to relieve the grid runs more often, and everything around it feels the difference: the air permit, the fuel contract, the noise assessment, the maintenance interval and the neighbours' patience. Similar fights over test hours and boundary noise are already being written into local rules elsewhere, as in our report on a Georgia county's draft limits.
Anyone quoting for a Malaysian data centre now should ask the operator whether the sets are expected to take part in demand control, and wait for the Energy Commission text before fixing the duty in a specification.
