Key takeaway

Korea would cut industrial power rates outside the capital region, naming data centres as intended beneficiaries.

South Korea's Ministry of Climate, Energy and Environment and the state utility KEPCO set out a regional electricity pricing scheme at a public hearing on 26 August, dividing the country into four broad zones refined into eleven pricing zones, with Jeju excluded ¹. KEPCO, the Korea Electric Power Corporation, is the state-owned utility that generates and sells most of the country's power.

Industrial rates outside southern Seoul and southern Gyeonggi would fall under the proposal, for an estimated 2.8 trillion won of annual industrial savings, and the ministry named new semiconductor clusters and data centres as the intended beneficiaries ². The hearing opens a consultation, and no tariff has been set.

Uniform national pricing tells a developer nothing about where the grid has headroom. Charging less away from the capital region pays that developer to build where the network can carry the load, which reverses the instruction congestion around Seoul gives today. Ofgem reached for price too, charging British grid applicants by the megawatt for the offers they hold . One instrument sorts serious applications from speculative ones and the other steers geography, and both replace a queue ordered by the calendar with one ordered by cost.

Deep Analysis

In plain English

Building near Seoul costs South Korea's grid more, because the region's infrastructure already runs close to capacity, so the government wants to price big new users toward places that are cheaper to serve. South Korea's plan would make electricity cheaper for big users, including data centres and chip factories, if they build further from Seoul, spreading new demand to parts of the grid with more room to spare.

Deep Analysis

Root Causes

Seoul and its surrounding province already carry the country's most congested grid infrastructure, so adding large new industrial and data-centre loads there raises transmission and reliability costs faster than adding the same load elsewhere.

Pricing electricity lower outside the capital region reflects that underlying cost difference rather than a subsidy invented for data centres specifically, and is intended to make the cheaper-to-serve regions economically competitive with the capital for large new connections.

Different Perspectives

NVIDIA

NVIDIA told the Securities and Exchange Commission on 26 August it had signed memorandums aiming to mobilise over $500bn for buyers' equipment purchases, then said in the same filing the arrangements may not become definitive. It may also carry limited residual-value risk on the equipment itself.

IREN Limited

IREN signed $2.4bn of financing on 25 August that only releases cash once its Mackenzie GPU servers are accepted, and only through 31 December 2026. A shipping delay from here now creates a funding problem as well as a revenue one.

Energy Commission (Malaysia)

Malaysia's Energy Commission recorded data centres at 9.3% of national power in one hot week in August, against a 7% year-to-date average, and is projecting 31% of peninsular demand by 2035. It wants roughly 9 GW of new gas-fired capacity by 2032 to cover the gap.

Economic Development Board and Infocomm Media Development Authority

Singapore's EDB and IMDA rationed 200 MW across four operators on 21 August and followed with a tropical liquid-cooling standard six days later, fixing the terms before construction starts. The agencies will decide within 18 to 24 months whether to run a third call.

Legal Resources Centre

The Legal Resources Centre put the water and power draw of two approved Cape Town Equinix sites in public, at roughly 4.4 billion litres and 1.4 to 1.5 billion kWh a year, because the city and the operator would not. It wants a cumulative assessment before any more of the five approvals proceed.

Ministerio de Minas e Energia

Brazil's energy ministry published Redata's five conditions after the Senate passed PL 278/2026 on 1 September, betting a repeatable annual water test enforces cooling design better than a one-off approval. Redata now needs President Lula's signature before any of it takes effect.
