Grid Modernization

Turning your smart grid ideas into reality.

The collision of Power Generation and Big Data has resulted in a world of distributed generation (DG) requiring a more real-time, intelligent, networked, and secure power grid than aging equipment can support. Smart Grid operations require substation devices that can accommodate supervisory control and data acquisition (SCADA), human machine interface (HMI), digital fault recorders (DFR), phasor measurement units (PMU), smart metering, and intelligent electronic devices (IED).

Sargent & Lundy has a proven track record of completing projects across the United States and internationally that support smart grid implementation, including new substation designs, solar and wind energy designs, battery energy storage, grid interconnection, load flow studies, and cyber/physical security projects along with hundreds of NERC CIP compliance upgrades.

Our depth of experience, staff resources, quality focus, and proven processes can effectively support your next Grid Modernization project along with providing turnkey solutions for project management, construction management, and implementation services.

Grid Modernization Substation Engineering Services 

Sargent & Lundy is ready to put the depth of its energy experiences, personnel resources, quality focus, and proven processes to work on your next assignment.

Substation automation and cybersecurity protection have advanced tremendously in recent years and now include services and components that were once discrete devices. The type and amount of information exchanged between intelligent electronic devices (IEDs) and supervisory control and data acquisition (SCADA) systems within a power system are increasing, compounding the security risks associated with keeping a substation’s local area network (LAN) free from cyber intrusions. Sargent & Lundy has the experience and technical expertise to unite all of these services and devices into a custom package designed to securely fit your specific substation automation and data needs.

Technical Overview:
• Completed hundreds of physical security and cybersecurity related projects over the last
decade for North American Electric Reliability Corporation (NERC) Critical Infrastructure
Protection (CIP) sites ranging from 115 kV to 500 kV
• Human-machine interfaces (HMIs), SCADA remote terminal units (RTUs), input/output
(I/O) modules, programmable logic controllers (PLCs), IEDs, metering
• Firewalls, routers, switches, ethernet, Synchronous optical networking (SONET),
microwave, wireless
• Intrusion prevention systems (IPS), intrusion detection systems (IDS), communication
processors, data gateways, access management

We have a proven track record of focusing our wide range of resources to create unique solutions that satisfy specific client needs. We pair precise technical and consulting skills along with the critical experience needed for the success of each engagement. The resulting scope of our services matches the breadth and depth of the technical issues that need to be considered to successfully and securely implement substation automation projects.

Grid Modernization Consulting Services

Sargent & Lundy’s grid modernization consulting services are available to help you integrate smart grid technologies into your business to provide you with more reliable and sustainable energy in the most economic way.

As penetration levels of renewable generation, like wind and solar, surge and grid reliability becomes increasingly vital to operation, Sargent & Lundy can help you evaluate assorted technological solutions that best suit your needs—such as micro turbines, batteries, and/or solar for your microgrid. We can support your grid modernization efforts, from determining the most economic selection of renewable or traditional generation resources to developing a plan for integration of cutting edge smart grid technologies.

Our experience includes microgrid evaluations, distributed energy resources (DER), energy storage development, resource planning, and capital cost and operations and maintenance (O&M) estimate development.
