SK E&C, a South Korean renewable energy developer, surged over 55% in July, closing at 80,600 won on the 23rd with a 30.00% single-day gain — a record high. The rally occurred as the KOSPI index fell from mid-8,000s to early 7,000s during the same period. The surge was driven by a renewed Middle East conflict that pushed WTI crude oil prices up 24.94% in the month to $86.83 per barrel from the $60s range last month, spotlighting renewable energy as an alternative to fossil fuels. Additional catalysts included New York state's AI datacenter construction moratorium announced on the 14th, which highlighted power supply as a critical infrastructure bottleneck, and SK Group's joint venture with KKR announced last month.
SK E&C Stocks Hit Record High on the 23rd
According to Korea Exchange data on the 24th, SK E&C closed at 80,600 won on the 23rd, up 18,600 won (30.00%) — the highest price in the company's history. The stock's July gains reached 55.90%, and compared to the short-term low of 41,200 won on the 8th, the stock surged 95.63% in 10 trading days.
Other renewable energy stocks also rallied: OCI Holdings (+30.00%), HD Hyundai Energy Solution (+29.73%), SK Oceanplant (+19.61%), CS Wind (+12.64%), Hanwha Solutions (+10.50%), Shinsung E&G (+9.29%), and OCI (+5.75%).
WTI Crude Surges 24.94% in July Amid Middle East Conflict
West Texas Intermediate (WTI) crude oil futures for the nearest month reached $86.83 per barrel on the 22nd (local time) at the New York Mercantile Exchange. Last month, WTI prices had fallen to the $60s per barrel as the US and Iran signed a ceasefire memorandum of understanding (MOU) and pursued war termination. However, prices surged 24.94% in July as the conflict reignited. Concerns grew that global oil supply could face further disruption as both the Strait of Hormuz and the Red Sea faced potential blockages.
Renewable energy stocks had previously rallied in March and April when the US-Iran conflict first erupted and international oil prices climbed steeply. Nuclear power stocks also rose during that period. Renewable energy gains prominence as an alternative whenever geopolitical uncertainty in the Middle East threatens fossil fuel supply chains.
Renewable Energy Cost Competitiveness Strengthens Against Fossil Fuels
Han Byung-hwa, a researcher at Yugin Investment & Securities, stated that the levelized cost of energy (LCOE) gap between combined-cycle gas generation and onshore wind power widened from $17 per MWh last year to $22 per MWh this year, while the gap for solar power expanded from $20 to $21 per MWh. Renewable energy has already surpassed gas generation in cost competitiveness, and the gap continues to widen.
Han added, "The NIMBY (Not In My Backyard) phenomenon against datacenters spreading across the US is likely to worsen after the midterm elections. Datacenter construction relying on fossil fuels will face more opposition going forward."
AI Datacenter Power Demand Drives Renewable Energy Focus
SK E&C's acceleration mid-July coincided with New York state's moratorium on large AI datacenter construction and permitting on the 14th, citing grid overload concerns. The announcement highlighted power supply as an immediate bottleneck in AI infrastructure expansion.
Hwang Sung-hyun, a researcher at Yugin Investment & Securities, explained, "Power procurement costs in the US are rising sharply due to permitting and grid connection issues. Oracle initially planned to build its own gas turbines for a New Mexico AI campus, but switched to Bloom Energy fuel cells after environmental permits were delayed."
SK Group Announces KKR Joint Venture and Datacenter Plans
SK Group's pursuit of datacenter construction in South Korea with Amazon Web Services (AWS) and other global tech companies also boosted investor sentiment toward SK E&C, given the company's leading position in domestic renewable energy development.
Last month, SK Group announced the establishment of a renewable energy joint venture with global private equity firm Kolberg Kravis Roberts (KKR). Government policies to activate Power Purchase Agreements (PPAs) also contributed positively to the stock's performance.
