LS Power 125 MW Solar Power Facility

In 2011, LS Power awarded Fluor an engineering, procurement, and construction contract to design and build a new, 125-megawatt solar photovoltaic (PV) facility in Arizona.

The Arlington Valley Solar Energy II (AVSE II) project uses more than 600,000 PV panels to harness the power of the sun in order to provide clean energy for the region.

The AVSE II facility, which is the size of approximately 516 football fields, uses single-axis trackers to adjust the panels to match the movement of the sun.

Fluor's construction team completed the clean power project in Maricopa County, approximately 45 miles west of Phoenix, Arizona.

Fluor was also awarded a five-year contract to provide operations and maintenance services after the facility was commissioned.

The AVSE II facility is one of the largest solar power projects in Arizona.

The facility produces 125 megawatts of power to help meet the regional need for clean, renewable energy upon completion.


Client's Challenge

LS Power is a power generation and transmission company that has been involved in the development, construction, or operations of more than 25,000 megawatts of power generation throughout the United States.

The AVSE II project, located on approximately 1,160 acres, was LS Power's largest solar project to date.

The facility produces 125 megawatts of power to help meet the regional need for clean, renewable energy and reduces dependence on fossil fuels.

Fluor's Solution

AVSE II awarded Fluor a lump-sum contract in 2011 to design and build the facility, which provides clean energy to approximately 30,000 homes.

From its Irvine, California office, Fluor's engineers designed the AVSE II facility.


For the construction phase, Fluor self-performed the work, which included installing more than 1,000 miles of wire and cable and driving more than 130,000 piles.

Fluor's project team achieved the significant safety milestone of 500,000 safe work hours despite working in the unforgiving desert heat.

AVSE II also awarded Fluor a five-year operations and maintenance (O&M) contract at the new facility. With this award, Fluor continues its 35-year legacy of providing O&M services to clients in the power sector.


On May 1, 2013, LS Power, Fluor, and Arizona Governor Jan Brewer held a ceremony at the jobsite to celebrate the initial delivery of electric energy from the project.

The AVSE II project brought many benefits to the State of Arizona and Maricopa County, including construction and operations jobs and helps the region meet its renewable energy goals.

Fluor achieved substantial completion of the AVSE II facility in October 2013.
