## Resolving the Global Interconnection Queue Crisis

More than 2,500 GW of contracted solar, wind, and storage capacity currently sits stalled in utility connection queues globally—equivalent to four times the entire installed power capacity of the European Union.

The accelerator directly targets critical hardware constraints, prioritizing global standardization of transmission transformer ratings (220 kV, 400 kV, and 500 kV) and establishing multilateral advance procurement pooling to stabilize factory production slots across Western, Asian, and Latin American manufacturers.

## Targeted High-Voltage Corridor Funding for Emerging Markets

The initial financing tranches prioritize cross-border transmission backbones in Southeast Asia and Sub-Saharan Africa, supporting regional synchronous interconnection and reducing generator curtailment.

The initiative will track lead times for grain-oriented electrical steel (CRGO) and transformer bushings via an open-access supply chain transparency index.
