What This Briefing Covers
This briefing examines the projected growth in global grid capital expenditure and the concurrent supply chain constraints affecting critical grid equipment, specifically transformers.
The Data / What’s Happening
Global grid capital expenditure is projected to surpass $650 billion in 2026 — up roughly 5% year-over-year and more than double the level recorded in 2020 — driven by the global transition toward renewable energy (intermittent sources are expected to reach nearly 48% of global generation by 2040, up from 2% in 2010) and the need to upgrade aging electrical infrastructure (Rystad Energy via PV Magazine, June 6, 2026). Simultaneously, global transformer manufacturing capacity reached 4,700 GVA in 2025, supported by around 400 plants operated by more than 260 manufacturers (Rystad Energy via PV Magazine).
What’s Notable or Overlooked
While supply constraints are beginning to show signs of easing due to new OEM investments in diversified production lines, the capital expenditure required to modernize grids continues to outpace the immediate availability of critical hardware. The expansion wave in transformer manufacturing is expected to last through 2028, but near-term procurement remains heavily constrained by legacy lead times and raw material dependencies.
The Tension
The core tension lies in the mismatch between accelerating grid modernization timelines and the physical realities of equipment manufacturing and distribution:
- Global grid capex is projected to surpass $650 billion in 2026, representing a significant increase from previous years (Rystad Energy).
- Despite this demand, global transformer manufacturing capacity reached 4,700 GVA in 2025 (Rystad Energy).
- Capacity additions are forecasted at 200 GVA in 2026, indicating limited near-term relief for supply shortages (Rystad Energy).
- Consequently, extended lead times of 2 to 3 years for transformers persist in major markets like Europe and North America, double the average lead times seen in 2019 (Rystad Energy).
- To bridge this gap, the US remains the world’s largest importer of transformers, relying on international supply chains to meet domestic infrastructure demands (Rystad Energy).
Risks / Counterpoints
Future equipment pricing remains uncertain due to volatile raw material input costs, including copper, aluminum, steel, and oil. Additionally, while battery deployment and smart grid-enhancing technologies could theoretically reduce grid intensity by alleviating congestion, this does not eliminate the fundamental demand for core grid equipment. A general slowdown in broader electrification trends represents a downside risk to these projections, though a complete reversal of the trend is not currently anticipated.
