US-based Origis Energy has begun commercial operations of three more phases at its Rockhound Solar complex in Ector County, Texas, raising the site’s total working capacity to nearly 1GW-direct current.
The latest additions provide approximately 500MW-direct current of solar capacity and bring the project closer to becoming one of the largest renewable energy facilities in the US.

Upon completion, the company expects the site to surpass 2GW of combined solar and storage capacity by 2029.
The complex is expected to play a significant role in meeting long-term industrial energy requirements.
The expansion marks a significant development in construction as one of the largest renewable energy sites in the US.
Origis Energy CEO Vikas Anand said: “This milestone underscores Origis Energy’s ability to consistently execute at scale.
“Reaching nearly 1GW of operating capacity in Ector County, Texas, demonstrates the strength of our platform, the depth of customer demand, and our ability to deliver complex, multi-phase infrastructure projects with safety, quality, speed and certainty.”
The Rockhound complex, comprising the already operational Swift Air Solar sites, has been designed to supply energy to major international operators.
This is reflected in long-term agreements signed with companies such as Meta, Occidental, DSM-Firmenich and Bekaert.
Plans for the next stage of the Rockhound complex include approximately 1GW of additional solar generation and energy storage capacity.
Origis Energy is offering this phase for potential data centre co-location and long-term corporate power agreements, in response to ongoing interest from customers with substantial energy needs.
In addition to its commercial role, the complex supports grid stability and contributes to economic activity in West Texas.
The development forms part of Origis Energy’s broader approach to creating large-scale, phased energy projects to meet ongoing demand.
In March this year, the company secured approximately $545m in senior secured project financing to support three utility-scale solar developments in Ector County.
