3-Line Briefing
- SK Eternix shares closed at 80,900 won on the 24th. The stock gained 55.58% over the week.
- Expectations that the government will expand direct power purchase agreements (PPAs), combined with rising oil prices driven by Middle East risks, strengthened the buying case for renewable energy stocks.
- HD Hyundai Energy Solutions rose 48.96%, OCI Holdings 28.67%, and Hanwha Solutions 8.70%, spreading the rally across the solar value chain.
What's Changing
SK Eternix's rally is not simply a rotation among theme stocks. The market is re-pricing a combination of rising power demand, fossil-fuel price volatility, and the expansion of direct PPAs all at once. Renewable energy stocks, which had lagged the rebound in EV-related names, are now catching a broader demand narrative tied to AI data centers and power-grid bottlenecks.
The core issue is volume. SK Eternix develops, builds, and operates solar, wind, ESS, and fuel-cell assets, and also handles power trading. That gives it a structure that can capture revenue from power sales and operations, unlike companies that simply build plants and stop there. As direct PPAs expand, cash-flow visibility improves for operators that supply renewable power under long-term contracts.
This rally cannot be explained solely by other SK Group names such as SK Hynix or SK Square. Semiconductors handle the computing side of AI demand, while SK Eternix supplies one part of the power needed to run that computing. The essence of this rally is that the market's lens on green energy stocks has shifted from carbon neutrality to power infrastructure.
Numbers in Context
Looking purely at price action, the pace is fast. SK Eternix gained 55.58% over the week, closing at 80,900 won on the 24th. Over the same period, HD Hyundai Energy Solutions rose 48.96% and OCI Holdings 28.67%. That such gains occurred even in a correcting market reflects the fact that policy, oil prices, and power demand converged at once — this isn't a thinly traded theme play.
The underlying business figures are also worth checking. In May 2026, SK Eternix signed a 100MW solar direct PPA with a 25-year contract term valued at 502.3 billion won. Combined solar and wind direct PPAs now total 355MW, worth roughly 1.8 trillion won. Its fuel-cell business also added 80MW of distributed power generation through the commercial operation of the Chungju Daesowon Eco Park, bringing cumulative operating capacity to 169MW.
Winners and Losers
- SK Eternix: Holding direct PPAs alongside ESS and fuel-cell operating assets makes it the most direct beneficiary of policy expectations. Its 1.3GW offshore wind pipeline offers a long-term growth option.
- HD Hyundai Energy Solutions: In this solar value-chain rebound, expectations for a recovery in module and solution demand are reflected in the share price. Pressure from Chinese supply, however, still needs to be monitored.
- OCI Holdings: If the case for a shortage of non-Chinese polysilicon and wafer supply in the U.S. strengthens, its pricing power could recover.
- Hanwha Solutions: Its solar manufacturing business is linked to expected benefits from U.S. policy. Its share-price gain was relatively modest, but it remains a key large-cap name in this supply-demand (order flow) theme.
- LS ELECTRIC and HD Hyundai Electric: As renewable energy capacity grows, demand for power conversion, distribution, and transmission equipment follows. Grid investment may show up in earnings before the generation assets themselves do.
Risk Check
- With the stock up more than 55% in a single week, the near-term valuation burden has grown. New buying that chases price alone, without confirmation of new orders or earnings, is hard to justify.
- For expectations around direct PPA expansion to translate into actual revenue, conditions around plant acquisition, development, grid connection, and power sales all need to align.
- Rising oil prices boost interest in renewable energy, but if interest rates stay elevated, higher discount rates on power-generation assets could reduce project valuations.
- The solar value chain faces both policy tailwinds and oversupply at the same time. Whether material and module prices rebound will be the key factor determining margins.
Bottom Line
The SK Eternix rally has the characteristics of a legitimate re-rating driven by power shortages and PPA policy, but the next things to watch are not the share price itself — they are new PPA disclosures, ESS utilization rates, the offshore wind construction schedule, and interest-rate levels.
