Tokyo Electron Korea Secures Korea’s Largest 50‑MW Direct Renewable PPA with KT

*TL;DR: Tokyo Electron Korea and KT Corp have locked in a 50‑MW direct renewable power purchase agreement, the largest such deal by a foreign semiconductor equipment firm in South Korea.

Context South Korea’s push for corporate renewable procurement is accelerating, with companies seeking to meet RE100 commitments—voluntary pledges to source 100 % of electricity from renewable sources. Direct power purchase agreements (PPAs) let corporations buy electricity straight from generators, bypassing the traditional market and guaranteeing a fixed supply of clean energy.

Key Facts - Tokyo Electron Korea and KT Corp signed a memorandum of understanding for a 50‑MW direct renewable PPA on May 11. - Under the forthcoming contract, KT will begin delivering 15 MW of renewable electricity to Tokyo Electron Korea in September, with plans to scale up to the full 50 MW. - The agreement covers the Hwaseong office and semiconductor process R&D centers, aiming to meet the sites’ entire annual electricity demand with renewable power. - Lee Sun‑gil, chief technology officer at Tokyo Electron Korea, called the deal “a highly important step” in the company’s sustainability roadmap, emphasizing the need for stable eco‑friendly energy to satisfy customer greenhouse‑gas reduction targets. - KT’s head of enterprise business, Kim Yong‑nam, described the partnership as a “new milestone” for Korean manufacturers transitioning to renewable energy, positioning KT as a carbon‑neutral platform provider.

What It Means The 50‑MW PPA marks the largest direct renewable contract signed in South Korea by a foreign semiconductor equipment supplier, signaling confidence in the country’s renewable supply chain. For Tokyo Electron Korea, the agreement secures the infrastructure needed to shift key facilities to 100 % renewable electricity, directly supporting its customers’ climate goals and bolstering the broader semiconductor ecosystem’s sustainability.

KT gains a foothold to expand its private‑sector direct‑PPA business, leveraging an intelligent renewable energy supply network that could be replicated across other industrial users. The deal also illustrates how Korean utilities are positioning themselves as enablers of corporate decarbonisation, a trend likely to intensify as more manufacturers adopt RE100 targets.

Looking Ahead Watch for the rollout of the remaining 35 MW of renewable capacity and how other foreign manufacturers respond with similar renewable contracts in South Korea’s fast‑growing clean‑energy market.
