Power & Possibilities
A permit is not an operating plant. A battery is not a fuel supply. Follow what each project can deliver—and what happened on its way there.
Generation creates electricity. The plant’s rating is not its annual output.
MW measures discharge power; MWh measures how much energy a battery can hold.
Transmission moves electricity. A line’s capacity is not new generation.

Hurdles can be historical or unresolved; matching a filter does not mean a project is currently blocked. Checked September 7, 2026.
Holtec reported the start of fuel loading on August 30, 2026, a step toward—not proof of—commercial generation.
Refurbishment and fuel loading are documented restart steps; commissioning is not yet commercial service in this source.
Constellation reported interconnection-rights and fuel-license progress in August 2026, with restart still targeted for 2027.
The operator reports that a waiver addressed a capacity-interconnection-rights requirement.
Restart remains a future milestone despite the reported licensing progress.
Hitachi Energy and Pattern Energy reported the transmission link fully operational in June 2026.
No specific blocking cause established in the linked record.
The developer reported commercial operation by June 16, 2026, while describing temporary restrictions on contracted energy sales.
Temporary market restrictions were reported at launch; the linked record does not document their later resolution.
NRC’s docket records the construction-permit decision on March 9, 2026. Operating approval is a separate step.
Construction approval is documented; the plant still needs a separate operating license before it can operate.
The 1,200 MW line entered commercial operation on January 16, 2026, after a referendum and litigation interrupted its development.
The referendum and vested-rights dispute interrupted the route to construction; the record now includes operation.

LADWP reported using the new natural-gas units in December 2025. Hydrogen blending remained a future step in the cited announcement.
No specific blocking cause established in the linked record.
DOE terminated its conditional Phase 1 financing commitment in July 2025. The developer continues to describe a privately led transmission proposal.
A conditional guarantee was withdrawn; subsequent financial close is not confirmed by these sources.
The developer announced full commercial operation in July 2024, after reporting supply-chain and inflation challenges.
The developer says it navigated supply-chain and inflation challenges before service; it does not identify them as current blockers.
SRP identifies Sierra Estrella as a 250 MW, four-hour battery that entered service in 2024.
No specific blocking cause established in the linked record.

This is not a national inventory, an opposition rate or a list of dedicated AI power supplies. Capacities describe different equipment and are not added into one total. Historical hurdles are not automatically current delays.
