Overview
Elon Musk announced on X that SpaceX and Tesla are planning to build solar production capacity of 100 gigawatts per year. He added that natural gas will still be required to supplement and support solar power for several years. Musk also stated that the limiting factor for natural‑gas turbine production is the casting of blades and vanes, and that by bringing blade‑and‑vane casting in‑house at SpaceX, turbine deployment could be accelerated by up to 18 months.
Market Reaction
Following Musk’s announcement, pre‑market trading saw Howmet Aerospace (NYSE:HWM) shares decline by 7 percent, GE Vernova (NYSE:GEV) fall 3 percent, and Siemens Energy (ETR:ENR) drop 4.4 percent in Frankfurt trading.
Analyst Commentary
Bloomberg Intelligence analyst Omid Vaziri interpreted Musk’s comment as validation of a scarcity in gas‑turbine blades rather than a direct threat to Siemens Energy. Vaziri noted that Siemens Energy is already expanding its ceramic‑core and casting capacity internally, which should ease the near‑term delivery bottleneck and support higher‑margin aftermarket demand well beyond 2030 as the installed fleet grows.
Implications
The announcement links the renewable‑energy expansion (solar) with continued reliance on natural‑gas infrastructure, highlighting a transitional period where both technologies coexist. The potential 18‑month acceleration in turbine availability could affect supply chains for gas‑turbine manufacturers and downstream power‑generation projects.
