Why prices sit where they do

South Korea buys electricity more cheaply than any other developed market in the region: commercial power at $0.118/kWh sits below Japan's $0.201, under half of Singapore's $0.262, and closer to Malaysian and Thai levels than to its neighbours. That does not produce cheap racks. The operator bench is telco-anchored, with LG Uplus alongside Digital Edge, Digital Realty and Equinix, and domestic carriers bundle network with space, which shortens the list of genuinely comparable quotes a buyer can assemble. Supply is also arriving ahead of the curve rather than behind it: 3 of the 7 facilities we track are still in pipeline and 4 of 7 are marketed as AI-ready, so what comes online is dense-rack capacity priced for it. Korea is a north-Asia node rather than a transpacific one, at 68 ms to Singapore against 185 ms to Northern Virginia. Insist that power be quoted as metered pass-through at the regulated industrial tariff, not as a bundled allowance.

Why is colocation priced the way it is in South Korea?

Commercial electricity in South Korea is $0.118 per kWh, and power is the largest single input into a colocation rate.
