Global Grid Capex and Transformer Bottlenecks

Global grid capex is projected to exceed $650 billion in 2026, driven by renewable integration, while transformer manufacturing faces extended lead times and capacity constraints.

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:

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.
