Terraform: Cheapest Solar in North America at $0.016/KWh

Terraform Industries’ Project Muroc was a rapid effort to build an off-grid fuel-synthesis test site in Southern California, anchored by a 1.8-megawatt solar array. The account argues that new utility-scale solar in the United States need not take years or cost the roughly $1.40 per watt the team had been warned to expect: with urgency, persistence, and close engagement with local officials and contractors, its team moved from land closing to permits and groundbreaking in 58 days. The site received 2,984 panels, installed in ten working days, and the team reports completing field construction in 50 days. The project cost $1.3 million including land and site improvements; Terraform calculates the array’s amortized electricity cost at $0.016 per kilowatt-hour, which it calls the cheapest in North America.

The account also emphasizes the risks of building while designs and expertise are still developing. Terraform divided permit applications so separate workstreams could advance in parallel, but a county fire department rejected its battery permit under stricter local requirements, forcing a redesign for AC power and leaving the company with sunk costs. An underperforming electrical contractor had to be replaced, and roughly $60,000 went to errors and other first-project costs. The team’s lessons are to keep backup contractors, avoid major equipment purchases before permits are secured, and give engineers stable constraints despite changing designs. The completed infrastructure is now supporting further experiments: Terraform says its teams have produced off-grid carbon dioxide, hydrogen, and methanol at the site.
