$3.5B Solar-Plus-Storage Project Closes Financing in Arkansas — 2.45 GW Build-Out Ahead
According to Oklahoma Energy Today, developer Cypress Creek Renewables has closed $3.5 billion in financing for the Steel River Energy Center — one of the largest solar-plus-battery projects in the United States — with the first two phases targeting 1.63 GW of solar and 1.9 GWh of energy storage in northeast Arkansas.
The financial close covers construction and long-term operation of the first two stages of the three-phase development in Mississippi County, Arkansas. The project is being built for an undisclosed tech firm under a virtual power purchase agreement. When all three phases are completed, Steel River will comprise 2.45 GW of photovoltaic farms and 2.9 GWh of battery energy storage systems (BESS), with commissioning targeted by 2029.
Solar panels across Phases 1 and 2 will be supplied by First Solar. Cypress Creek acquired the Steel River project in March from developer Swift Current Energy. The company currently operates or has under construction over 6.8 GW of assets and maintains a development pipeline totalling 19 GW across the United States.
What It Means for Subcontractors
A $3.5 billion construction close of this scale sets off a multi-year procurement and build cycle for field service companies operating in the Mid-South and adjacent regions:
- Civil and site preparation crews will be in demand across the large footprint of a 2.45 GW solar farm in Mississippi County — grading, road construction, drainage, and fencing at utility scale
- Electrical subcontractors face a substantial scope: racking installation, inverter and combiner box wiring, medium-voltage collection systems, and substation work for a gigawatt-plus project
- BESS specialists should note the 2.9 GWh storage component — battery enclosure installation, thermal management, DC/AC integration, and commissioning require specialized field crews
- Balance-of-plant (BOP) contractors experienced in utility solar will find that a three-phase project of this size generates recurring work packages as each phase moves from groundbreaking to energization
- Equipment operators for utility-scale earthworks in northeast Arkansas should begin monitoring pre-qualification announcements from Cypress Creek Renewables and its EPC partners
With commissioning targeted by 2029 across three phases, the project will generate sustained construction activity over the next several years. Contractors with experience in First Solar module handling and high-density battery energy storage integration should position early.
