More than 32 gigawatts (GW) of planned data centre capacity spread across over 1,150 projects is reshaping how power grids accommodate large electricity users across Asia-Pacific, with regulators introducing new requirements on reliability, flexibility and clean energy procurement as electricity demand surges, according to consultancy Wood Mackenzie.
In a report released on last week, Wood Mackenzie said data centre developers are increasingly being required to install battery storage, manage curtailment risks and support grid stability in order to secure access to constrained electricity networks.
The report, Asia-Pacific power grids are redefining the rules of data centre access, examines how governments and regulators across eight key markets are responding to rapid growth in electricity demand driven by data centres.
“For many developers, securing power is becoming more challenging than securing land, financing or permits,” said Xiaonan Feng, principal analyst for Asia-Pacific power and renewables at Wood Mackenzie.
“Across Asia-Pacific, grid availability is emerging as the defining constraint on data centre growth,” Feng said.
The consultancy said regulators are increasingly moving away from the traditional model in which utilities alone were responsible for providing reliable power to large consumers.
Instead, policymakers are introducing frameworks that require data centre operators to share responsibility for grid reliability, flexibility and decarbonisation. The measures generally fall into four categories: conditional access, geographic diversification, grid-support requirements and capacity controls.
In Japan, regulators are exploring mechanisms that would allow facilities to connect to the grid before reinforcement works are completed, provided operators install technologies such as load-shedding systems or battery storage that enable demand reductions during grid stress events.
While such arrangements can accelerate access to power, they also raise project costs and increase operational complexity, the report added.
Governments are also seeking to direct future data centre growth away from congested metropolitan areas. Japan, India and South Korea are introducing incentives and policy frameworks designed to encourage development in regions with stronger grid capacity and access to lower-carbon electricity supplies.
Australia is among the first markets in the region to require large data centres to play a more active role in supporting grid stability. Proposed rules would require facilities larger than 30 megawatts to remain connected during voltage and frequency disturbances and to restore demand gradually after grid events.
Wood Mackenzie said similar requirements are likely to emerge elsewhere in the region as renewable energy deployment accelerates and electricity demand from large users continues to grow.
Meanwhile, Singapore, Malaysia and South Korea are increasingly relying on regulatory controls to manage access to constrained power systems. Requirements related to energy efficiency, renewable energy procurement and grid impact assessments are raising barriers to entry and favouring larger operators with greater technical and financial resources.
The consultancy said new power-related costs are becoming a structural feature of data centre development in the region, with battery storage, self-firming requirements, renewable energy procurement obligations and curtailment management increasingly factored into project planning.
“The cost of power is no longer limited to electricity bills and connection fees,” Feng said. “Storage, curtailment management and clean energy obligations are becoming core infrastructure requirements that can materially affect project economics.”
