The US government is lending nearly $3 billion to support the restart of two shuttered nuclear reactors, with Google and Microsoft signing long-term power purchase agreements to supply their AI data centers. This marks a shift from new small modular reactor (SMR) builds to refurbishing existing nuclear plants as a cost-effective, low-risk source of carbon-free power.
This Wire brief sits within Fusion42's coverage of Clean Energy.
◆ ◆ The Wire takeaway
You face a new standard for clean power contracts as Google and Microsoft back existing nuclear plants with federal loans. This means your nuclear startup must match the cost and certainty of these restarted reactors or lose access to capital for years.
