Enlight Renewable Energy has reached final development milestones for its CO Bar complex in Arizona, clearing the way for full-scale execution of the company’s largest project to date.
The five-stage development totals 1.2GW of solar capacity and 4GWh of battery storage. Enlight said it has secured a 1GW interconnection agreement alongside 20-year energy service agreements for the CO Bar 4 and CO Bar 5 storage phases.
The full project is expected to generate USD264–278 million in electricity sales during its first year of operation and will require total investment of USD2.86–3.01 billion, or USD1.55–1.63 billion net of tax benefits.
Construction has begun on CO Bar 1 and 2, with full mobilisation on CO Bar 3 through 5 due within the next 12 months. Staged commercial operations are planned from the second half of 2027 through the first half of 2028.
“CO Bar represents a major step forward for Enlight’s U.S. platform,” said Adi Leviatan, chief executive of Enlight.
“Reaching full interconnection and completing the commercial framework for such a large-scale, integrated solar and storage complex demonstrates our ability to execute at scale, deepen partnerships with leading utilities, and deliver long-term value from high-quality renewable assets.”
Jared McKee, chief executive of Clēnera, said the project highlights the company’s capability to deliver large utility-scale developments.
“The CO Bar project signifies Clēnera’s ability to build large utility-scale solar facilities that not only generate and store reliable clean energy but also support regenerative land management principles,” McKee said.
