A History of Power Clientship

Sargent & Lundy shares its history with the history of the electric power industry. The industry was just emerging when engineers Frederick Sargent and Ayres Lundy formed an independent engineering and consulting company in 1891, dedicated to working with clients in the electric power business.

Individually, they had earned recognition for their technical talent and foresight. Sargent was one of Thomas Edison's most capable early associates while Lundy was a highly regarded colleague of electric railway innovator Frank Sprague. Together, they collaborated on power generation and transmission projects that advanced the industry and set the company's course.

The firmís first project was the Harrison Street Station, which received worldwide attention for its power generation and transmission innovations. It was the largest plant in the U.S. and its first-ever design using condensing engines slashed in half the coal needed to produce a kWh. Output was carried over transmission lines for a revolutionary length of 3,340 feet.

This project was the first of many bold explorations of diverse technologies that have helped Sargent & Lundy clients succeed through each era of power industry change.

Sargent & Lundy's nuclear power leadership began in the mid-1950s, when we designed the world's first boiling water reactor installation at Argonne National Laboratory and converted the Arco Borax III research reactor to an electricity producer.

Today, Sargent & Lundy has designed more than 30 increasingly advanced units and has been continuously engaged in nuclear power work since the beginning.

Pioneering work in renewable energy began with SEGS VIII and SEGS IX. At 80 MW each these Solar Energy Generating Systems in the Mojave Desert were the largest solar thermal power plants in the world when they went on-line in 1989 and 1990. They continue to be the world's largest trough solar power plants.

Overall, we have engineered 931 power plant units and more than 6,200 circuit miles of power delivery systems. Many authorizations have been innovative power generation & transmission "firsts.Ē Many more weren't milestone undertakings, but instead were simply good, solid projects expertly engineered to meet the needs of their owners. We also have worked extensively to help our clients improve their existing assets, providing engineering as well as professional consulting services for several thousand installations.

With our comprehensive services, we have worked with more than 1500 clients in 82 countries... and still counting.

Our focus on the power business remains unchanged. We're still working with our first client as well as many other long-time clients. We have earned this extensive repeat business through our technical and project management know-how, our agility in meeting clients' evolving needs, and our integrity for acting in the best interests of each client.
