Lithia Solar Project

Location: Hillsborough County, Florida
Installed Capacity: 74.5 MW AC
Year Commissioned:  2018

The Lithia Solar Project is a 74.5 MW AC solar-powered electric generating plant located in Hillsborough County, Florida.  The facility utilizes thin film modules mounted on ATI DTHZ V3 FS4 tracker. The DC power generated by the panels is collected and converted to AC power by inverter stations distributed throughout the array field. The DC voltage is up to 1,500 V. The inverter station contains step-up transformers to raise the inverter output voltage to 34.5 kV for transmission to the project substation. RRC provided electrical engineering and SCADA engineering services for this project.

Desert Green Solar Field

Project Description

Location:   Borrego Springs, California
Project Capacity: 5 MW
Year Commissioned:   2014

The Desert Green Solar Project consists of a 5 MW solar farm with 240 dual-axis trackers, each supported on a single vibratory driven steel pile. Each tracker is mounted with a 25’ x 40’ tracker table covered in CPV panels. The large diameter piles required to support the panels are custom fabricated from rolled and welded steel plates. RRC met the project’s tight schedule and worked with our client to limit or eliminate cost increases that resulted from increased loading requirements due to changes in the tracker design.

1.34 MWdc Solar Pilot Plant

Project Description

Location:   New Orleans, Louisiana
Installed Capacity: 1.34 MWdc/1.08 MWac of energy
Year Commissioned:   2016

This project is a new photovoltaic generating facility utilizing conventional polycrystalline PV modules in a NexTracker Single-axis tracking system. A 0.5 MWac Battery Energy Storage System (BESS) is co-located, and for maximum flexibility is capable of charging from the grid or the PV system.

RRC optimized the PV plant design to achieve the lowest overall lifecycle costs and provided the land surveying, civil engineering, Stormwater Pollution Prevention Plan (SWPPP), geotechnical engineering, corrosion analysis, electrical engineering, pile loading testing, SCADA design and hardware engineering services, construction staking, construction support, permitting support, project management and as-built drawings for the project.

93.16 MWdc PV Solar Plant

Project Description

Location:   Lyon County, Minnesota
Installed Capacity: 93.16MWdc/62.25 MWac of energy
Year Commissioned:   2016

This project entailed the design of a 93.16 MWdc PV solar plant, with an optimized solar photovoltaic array and related infrastructure in Lyon County, Minnesota. Design employed a fixed tilt racking system with 330W solar modules and a system design voltage of 1500V.

RRC provided the electrical design, from the solar panels to the project main site substation/switchyard, optimizing the PV plant design to achieve the lowest overall lifecycle costs. The structural engineering for the site included reconfiguration and optimization of the racking and foundations resulting in project savings of over 1mm lbs. of steel. The soil conditions and freeze susceptible soil impact was mitigated with special attention to the structural design while maintaining cost competitiveness and constructability. RRC also provided construction support, project management, and as-built drawings.

95.6 MWdc PV Solar Plant

Project Description

Location:  Near Roswell, New Mexico
Installed Capacity: 95.6 MWdc/70 MWac of energy
Year Commissioned:   2016

This project entailed the design of a 95.6 MWdc PV solar plant, with an optimized solar photovoltaic array and related infrastructure near Roswell, New Mexico. Design employed a NexTracker single-axis tracker system with 290W, 315W and 330W solar modules and a system design voltage of 1500V and CITC voltage of 1000V.

RRC provided the electrical design, from the solar panels to the project main site substation/switchyard, optimizing the PV plant design to achieve the lowest overall lifecycle costs. This project included CITC equipment, which provided a special challenge to integrate. Creative design allowed the CITC use and captured a 30% project savings. RRC provided the civil engineering for the site, a Stormwater Pollution Prevention Plan (SWPPP) and Spill Prevention Control and Countermeasure Plan (SPCC), structural engineering for the 4MVA inverters, and corrosivity analysis for the direct buried copper grounding conductors, thermal resistivity testing, construction support, project management and as-built drawings.

4.39 MWdc PV Solar Array – Phase II

Project Description

Location:   Fort Campbell, Kentucky
Installed Capacity: 4.39 MWdc/3.1MWac of energy
Year Commissioned:   2016

The objective of this innovative solar project was to design a project that locally generated renewable solar electricity to enhance energy security and provide price stability for Fort Campbell and meet the Army’s renewable energy goals. The project was broken up into two phases with Phase II located on approximately 25 acres of a capped landfill.

RRC provided the land surveying, preliminary civil engineering, geotechnical engineering, preliminary electrical engineering, preliminary SCADA design and project management services for the Phase II project site. RRC optimized the PV plant design to achieve the lowest overall lifecycle costs.
