After nearly two decades, this massive New Mexico wind project is now powering California
The SunZia wind farm, the largest renewable energy project in U.S. history, began delivering power to California and Arizona on June 18 after nearly 20 years of development. While New Mexico's wind, solar, and battery capacity surpassed fossil fuels within five years, the federal government is simultaneously funding the cancellation of offshore wind projects. The Trump administration has paid energy firms nearly $4 billion to abandon developments off the coasts of California, New York, and Louisiana, including a recent $1.2 billion settlement with one offshore wind company.
What changed
The Trump administration has paid nearly $4 billion to cancel offshore wind projects, contrasting with the operational success of the SunZia project.

SunZia Wind Farm Powering West Amid Federal Offshore Wind Cancellations
The SunZia wind farm, the largest renewable energy project in U.S. history, began delivering power to California and Arizona on June 18 after nearly 20 years of development. While New Mexico's wind, solar, and battery capacity surpassed fossil fuels within five years, the federal government is simultaneously funding the cancellation of offshore wind projects. The Trump administration has paid energy firms nearly $4 billion to abandon developments off the coasts of California, New York, and Louisiana, including a recent $1.2 billion settlement with one offshore wind company.
Why it matters
The SunZia project relies on a 550-mile transmission line to move energy across state lines. This shift occurs as the U.S. manages a declared energy emergency and faces internal conflict over renewable energy priorities.
What is confirmed
- The SunZia wind farm began delivering power to Arizona and California on June 18.
- The Trump administration paid energy firms nearly $4 billion to cancel offshore wind projects.
- A settlement of $1.2 billion was reached with an offshore wind company to abandon projects off California, New York, and Louisiana.
Still unconfirmed
- Solar, wind, and batteries overtook fossil fuels in New Mexico in five years.
- The Trump administration's buyback of offshore wind leases resulted in less power at a higher cost.
What to watch next
- Further settlements regarding the buyback of offshore wind leases.
- Updates on state-level resistance to wind farm cancellations.
