Performance Drives Progress
By harnessing our extensive resources and expertise, we support energy projects at every stage, from early strategic planning through detailed design, procurement, construction, commissioning, and operations. Our service offerings include:
Transmission And Distribution (T&D)
We have more than 30 years of experience working on transmission and distribution projects and offer a full range of engineering and design services required to put systems in commercial operation. We deliver overhead and underground transmission and distribution line projects, from new line additions and extensions to capacity upgrades of existing lines, from 5kV through 765kV. We help develop and interconnect renewable generation sources in addition to leading electrification and grid modernization efforts, and can implement reliability and resilience improvements to address critical energy needs in remote areas.
Our team includes talented engineers and scientists with expertise in transmission and distribution line design, load-flow and short-circuit studies, pole line maintenance and inspection, surveying, power quality studies, system coordination and protection and distribution automation. Our skilled experts are knowledgeable about the latest technologies, renewable integration techniques and systems, and conservation tools required to maximize efficiencies in transmission and distribution lines.
Substation
Whether you’re modifying existing facilities or providing “greenfield” designs for new ones, substation projects pose many technical, environmental, regulatory, and physical hurdles. And our team is up for the challenge up for the challenge, offering depth and breadth of technical expertise and tools to develop creative solutions that meet your needs and expectations. From medium voltage commercial needs through 500kV utility applications, we can assist with obtaining the required easements, licenses, and permits to perform the work. Additional services include:
- Site selection
- Engineering
- Gas insulated design
- Structure design
- Licensing and permitting
- Foundation design
- Grounding plans
- Equipment specifications
- O&M plans
We have been executing and providing professional services for substation projects and programs for more than 30 years. We have delivered services ranging from program management to design engineering to full EPC delivery through self-performance and partnerships with industry leaders. We also assist clients in obtaining the required easements, licenses, and permits to perform the work. We have the ability and expertise required to make the right decisions and implement the perfect strategies on every project. Our proven project controls systems and intense focus on safety and quality bring projects in on time and within budget.
Hydropower
We offer a full range of services for dams, reservoirs, and hydroelectric facilities, and have completed more than 100 hydroelectric and water resource projects – with a total generating capacity in excess of 25,000 MW. Our projects cover operating heads from low-head Kaplan bulb and tube turbines to Francis units and high head impulse units. Our capabilities also include:
- Conventional high-, medium-, and low-head hydroelectric
- Pumped Storage
- Dams
- Spillways
- Tunnels/Caverns
- Inspections
Renewable Power Generation
The world’s energy market is changing in response to limited resources, increasing demands, fluctuating prices, and combatting climate change. Parsons maintains a leading position in the industry because we succeed in providing our customers with the most current technologies for their innovative projects across the globe.
Sustainability is one of our core values and we have a long history of promoting it across the markets we serve. We know major energy producers, consumers, utilities and the federal government all seek to reduce their carbon footprints and we have the tools to help. In addition to using state-of-the-art technologies, we have expertise in planning, designing, and building alternative energy facilities which use wind, solar, geothermal, biomass, and alternative fuels.
Gas Transmission, Distribution, And Storage
We have completed over 150 pipeline projects, including oil and gas field developments, gas processing plants, import/export terminals, flood mitigation, pump stations, compressor stations, meters, import/export terminals, and storage tank farms. The 21,000 miles of pipeline we have supported includes gas and water pipelines we designed and managed for power plants. They also include large-diameter pipelines—with multiple booster stations—that transport oil, gas, refined products, and water for hundreds of miles. We also offer planning, project management, design, procurement, management, and construction, as well as engineering services such as scoping, front-end engineering design (FEED), and detailed design.
Innovative Technology Solutions
Much of the infrastructure utilities rely on today are decades old. Power generation and distribution technology has not evolved at the same rate as nearly any other industry. We are here to help, with technology solutions that build resilience, streamline maintenance, and improve operations; and core services to design, build and maintain the grid while minimizing its impact on the environment.
We are a registered system integrator for AVEVA, a global leader in industrial engineering, design, and information management software. AVEVA’s solutions are deployed at more than 100,000 customer sites, serving industries such as oil & gas, utilities, refineries, pipelines, substations, transmission and distribution infrastructure, water processing, and more. With more than 40 trained experts, we offer support for numerous AVEVA capabilities including:
- Admin
- Catalog
- E3D
- PDMS
- P&ID
- Diagrams
- Electrical Engineering
We leverage our 20+ years of laser scanning experience in myriad ways. We can perform BIM back modeling for retrofit design, monitor construction progress, check craft installation tolerance, and create as-built documentation—to name a few.
Drones are an excellent way to do field surveys. They are especially useful for large sites, and they outperform traditional survey methods, which often require negotiations with regulators. Our dedicated drone team has performed assessments of bridge structures and transmission towers with great success. Because the drones reduce the need for excess equipment and personnel, they can cut the time and cost required to complete surveys, as well as reducing the number of safety incidents.
Starting with relays and sensor equipment, we use the latest technology to detect and control the energy flows between generators and the grid. As a company long steeped in advanced communications, we’ve helped develop standards for smart meters for grids and testing for limited utility applications. As a result, you can trust that we’ll provide expert, ongoing energy management analysis and studies.
Cybersecurity vulnerabilities in utilities present a major security risk. At Parsons, our infrastructure expertise informs our cyber capabilities, providing end-to-end solutions that anticipate, defend, and mitigate cyber threats across the spectrum. As the leading supplier of cybersecurity and operational technology security to the US Government and other commercial clients, we have the expertise and tools to protect and keep your information safe. We are also well versed in IEC 61850 CIP critical infrastructure protection compliance and will ensure each of the programs implements your policy where applicable.
VIQAS™ Inspect is a centralized, web-based system for performing virtual inspections. The VIQAS™ platform collects video and still imagery of a site. It then archives and backs up the data in a secure cloud environment. By logging into the platform from their computers, remote personnel can participate in an inspection in real-time. An additional benefit is that VIQAS™ provides 100% traceability by tracking what and where images are, who took them, and when.
Our teams have successfully managed programs of all shapes and sizes. With full-service offerings, no matter the complexity of your project, our team can help make it a success.
