Renewable Energy Integration

As renewable energy sources continue to replace traditional fossil fuel generation capacity, care must be taken to ensure that transmission systems remain stable and new generation sources are properly integrated with existing sources.

Integrating wind and solar generation poses particular challenges for transmission system operators, who must deliver uninterrupted bulk electric power despite the intermittent and variable nature of these sources.

SEL designs and commissions wide-area protection and control systems—also commonly called special protection schemes (SPS) and remedial action schemes (RAS)—that ensure transmission system stability and provide wide-area situational awareness.

Enhancing the stability and capacity of existing transmission lines can potentially free up billions of dollars in capital expenditures. In some cases, utilities can operate transmission corridors at a higher capacity after the RAS/SPS is implemented, increasing revenue and freeing up capital expenditure.

SEL offers modernization solutions and services for any part of the grid, scaled to your needs. Partner with us on individual projects or multi-year modernization programs.

We design electric power systems, coordinate procurement and construction, manufacture the relays, build the panels, and install and commission the protection and control systems.

• Simplicity at Every Stage—Streamline your grid modernization program with a single PO. We offer a single-vendor solution for the entire process—from design and permitting through building, installation, and commissioning. This simplifies budgeting, project management, and timelines, ensuring on-time delivery.
• Advanced Technology—SEL solutions offer the fastest protection available. They also improve systemwide visibility and control through cybersecure remote engineering access, automated event collection, and precise fault location, among other benefits.
• Access to Experts and Product Support—Engineering support is available to you before, during, and after a project. After commissioning, you receive 24/7 support from SEL application engineers. Technical support is available for the lifetime of every SEL device at no cost.
• Reduced Total Cost of Ownership—Our simplified project management approach, advanced technology, and expert support lower your O&M costs in the short term and for the entire life of your modernized system.

We believe you should never have to worry about whether your protection and control systems will be working when you need them most. That’s why you always have access to SEL engineers—and every device we manufacture comes with a ten-year warranty and free technical support.
