Hong Kong Targets 70% Zero-Carbon Power by 2035 to Draw AI and Data Centre Investment
The city's clean energy ambitions hinge on grid reliability and market reform, analysts warn, without which multinationals and data centre operators will look elsewhere.
Hong Kong's Environment and Ecology Secretary Tse Chin-wan told the Legislative Council in July that the government aims to lift zero-carbon electricity from roughly 25% of the fuel mix to as much as 70% by 2035, primarily by importing more clean power from mainland China. The shift would represent one of the more aggressive grid decarbonisation timelines in the region.8
Analysts said the plan could strengthen Hong Kong's pitch to multinational companies, AI developers, and data centre operators hunting for jurisdictions that can offer clean, certified power at scale. But they were cautious. Reliable supply and affordable tariffs are prerequisites, not outcomes, and neither is guaranteed by a target alone. Market reforms would need to accompany any grid overhaul for businesses to realise tangible benefit, analysts said.8
The timing is deliberate. Across Asia-Pacific, more than 32 gigawatts of planned data centre capacity spanning over 1,150 projects is already reshaping how grids accommodate large electricity users, with regulators tightening requirements on reliability, flexibility, and clean energy procurement as load grows, according to eco-business.com. Hyperscalers are prioritising scalability and delivery certainty, and upcoming pipeline projects are frequently measured in the hundreds of megawatts, with some approaching gigawatt-scale, as reported by Yahoo Finance in late May (2026-05-26).7,4
Hong Kong is entering this race from a structurally weak position on cost. Chinese data centres on the mainland can secure power for around three cents per kilowatt-hour, according to official figures — roughly half the rate many American facilities pay. Hong Kong's grid tariffs sit considerably above that level, and closing the gap requires more than a clean energy import agreement.2
The mainland connection cuts both ways. Importing renewables from China solves the carbon accounting problem but introduces a supply dependency that some multinationals, particularly those subject to US compliance requirements or reputational scrutiny, may weigh carefully. Chinese grid operators have also shown resistance to plans to significantly raise the share of renewable electricity powering AI workloads, citing concerns about forecasting peak demand at data centres, oilprice.com reported in June (2026-06-22). That resistance reflects genuine technical risk, not just institutional inertia, and it complicates assumptions about how smoothly clean power can be dispatched on demand.6
Southeast Asia offers a useful comparison. Power demand from data centres, EVs, and green industrial parks across the region is forecast to grow by more than 100 terawatt-hours over the next three to four years, requiring over $200 billion in investment, according to a report cited by ESG News (2026-05-20). Yet the same report estimated an $18 billion annual shortfall in grid investment by 2035 — a gap that shows the distance between stated ambition and funded execution across the broader region.1
China's own posture adds a layer of context. Beijing launched an action plan earlier this year targeting deep integration of AI and the energy sector by 2030, with a focus on clean energy supply, energy data utilisation, and AI model innovation, Asian Power reported (2026-05-15). That plan positions the mainland as a competitor for the same class of investment Hong Kong is now courting, with the advantage of lower power costs and greater grid scale.3
Chinese energy companies are also positioned to play a significant role in regional grid integration, with Southeast Asian countries working toward a cross-regional power network, a senior Singaporean official noted, as reported by The Star (2026-05-29). That regional interconnection agenda may eventually compress Hong Kong's geographic advantage as a gateway to mainland clean power, since direct grid ties from the mainland to other Asian markets would reduce Hong Kong's relative differentiation.5
For now, the 2035 target functions as a signal to property developers, data centre investors, and corporate sustainability officers making long-horizon site decisions. But the practical question is execution speed. Certification frameworks for imported renewable energy, tariff structures that pass through clean power at competitive rates, and grid upgrades capable of handling variable large loads — these are the variables that will either validate or erode the government's pitch. The next concrete indicator will be whether the regulatory and commercial architecture supporting the import agreements from Mainland China takes shape alongside the headline capacity targets, or lags behind them.8,7
