Projects

Coastal Grid served as the lead technical resource for protection and automation standards at a large California utility. In this role, we worked with all of the engineering teams to create and develop new substation protection and automation standards.

This work included developing standard schematic and logic prints, presenting changes to the standards committee, serving as subject matter expert, and publishing all related documentation.

As a subcontractor through Tesco Automation, Inc., we worked with the technology development department of a major California utility to implement a fully digital substation based around IEC 61850. This included developing test plans, configuring IEDs, and conducting thorough testing. 

In partnership with Tesco, we configured and tested the system in a lab environment. It was designed to replicate a full distribution substation, featuring both relays and merging units. A multi-vendor system was implemented to test interoperability between IEDs. For additional details, see Tesco’s website: Past Projects | Tesco Automation.

Coastal Grid has provided engineering services for over 20 individual Remedial Action Scheme (RAS) projects for one of the largest California utilities, including their critical Centralized Remedial Action Schemes (CRAS).

As one of a select few approved contractors for these projects, we are proud to consistently deliver reliable, high-quality services.

The Ultimate Dataset Project was completed for a large California utility. We developed a comprehensive set of standard pointlists for their latest substation automation system, based around IEC 61850. These pointlists covered all protection and automation applications across the utility’s entire system.

We implemented these points into the IEDs, primarily focusing on GE and SEL relays. As part of this effort, we upgraded the relay firmware to the latest versions and created the standard IEC 61850 SCL files.

As the lead technical resource for a major California utility, Coastal Grid updated and maintained over 250 standard IED configuration files. Partnering with the Standards and Protection/Automation teams, we developed templates for all protection and automation devices installed in the field. 

Our team upgraded the files to incorporate the latest technology, researching new features and providing recommendations for their implementation, with a particular focus on IEC 61850
