Digital Edge, the Singapore-headquartered data centre platform, plans to build a 120 megawatt facility in Bupyeong-gu, Incheon, in partnership with the South Korean developer SK Ecoplant. The company says it will be the largest commercial data centre project in the country, with a capital investment of more than KRW 1 trillion, or about USD 1 billion.

The project follows Digital Edge's acquisition of two sites in Seoul and Busan from Sejong Telcom in 2021. First-phase construction is to begin in 2022, with the site ready for service in 2024.

The arithmetic, and what it has to earn

A trillion won for 120 megawatts works out at roughly USD 8 million per megawatt of IT load, before financing costs and before the site is anywhere near full. That is a lot of capital to place ahead of demand, and it is why the anchor tenants matter more than the building.

The partner is a construction and energy company, SK Ecoplant, which brings development knowledge rather than customers. Digital Edge's chief executive, Samuel Lee, describes Korea as one of the fastest growing data centre markets, citing the country's fifth place in an industry cloud-readiness index — a ranking of market conditions rather than of demand for these particular racks.

Construction of the first phase has not started, the tenants have not been named, and the ready-for-service date is two years out. The number that matters is not the trillion won but how much of the 120 megawatts is leased when the doors open. SK Ecoplant brings construction and energy expertise rather than a customer list, so the occupancy risk sits with Digital Edge, in a market where local operators and the large cloud providers already have relationships of their own.
