115-kV Transmission Line

Siem Reap, Cambodia

Client: Asian Development Bank and Cambodia Power Transmission Lines

Parsons Brinckerhoff Role: Owner’s and Lender’s Engineer

Show Project Details

In Cambodia, a large electricity transmission project involved importing power from a substation in neighboring Thailand to meet urgent needs in northwest Cambodia. The project included the construction of three 115-kV/22-kV substations at regional centers in Battambang, Banteay Meanchey and Siem Reap; one 115-kV switching station; and 137 miles (221 kilometers) of a single-circuit 115-kV transmission line traversing three Cambodian provinces.

Parsons Brinckerhoff advised the Asian Development Bank and Cambodia Power Transmission Lines, a private joint venture, on technical, environmental and social issues, identifying all risks and offering mitigating solutions.

“Since energization of the facility in November 2007, Cambodians served by the new transmission lines have been less dependent on the more expensive option of small diesel generators,” said Fleur Parkinson, Parsons Brinckerhoff’s Environmental Scientist on the project. “Private shops and restaurants have been able to extend hours and invest income in their businesses that was previously spent on electricity.” Fuel imports and carbon emissions have also been greatly reduced.

About Power/Energy

Parsons Brinckerhoff is a leading provider of engineering and project management services to the global power/energy market. The firm offers expertise in power generation; transmission and distribution; energy services for buildings and facilities; and underground storage of hydrocarbons. Parsons Brinckerhoff’s history in power engineering dates to the turn of the 20th century, when the firm’s founder, William Barclay Parsons, supported development of hydroelectric power.

Parsons Brinckerhoff has extensive experience in all forms of power generation, from conventional technologies to innovative techniques that conserve resources and reduce environmental impact, including cogeneration, combined-cycle generation, and the production of power from renewable sources. Parsons Brinckerhoff has also participated in electrical distribution projects around the world, including projects to bring power to rural or developing communities, and has been recognized for its pioneering work in extra-high-voltage transmission. In addition, the company is one of the world’s premier designers and constructors of hydrocarbon storage caverns and related surface facilities, having worked on more than 2,200 storage projects worldwide, including major facilities such as the U.S. Strategic Petroleum Reserve.

Over the years, Parsons Brinckerhoff has made significant contributions to the state of the art. Parsons Brinckerhoff engineers invented and patented a technique to improve efficiency and reduce carbon dioxide and nitrogen oxide emissions during the desalination process. Company engineers later developed a hybrid power plant concept that combines nuclear and gas turbine technologies to meet efficiency and emissions-reduction objectives.

Today, Parsons Brinckerhoff maintains its leadership position in the power industry through the skills and experience of its power/energy experts, and a strong company commitment to technical innovation. The firm is dedicated to helping clients around the world meet the challenges of delivering electricity safely and efficiently, while reducing the impact of power plants on the environment.
