Smart Switching, Real Results: How IntelliRupter® PulseCloser® Fault Interrupters Are Transforming Reliability in The Bahamas

When the Bahamas Grid Company (BGC) launched its $130 million upgrade of New Providence’s power grid, the goal was clear: Deliver a stronger, smarter, and more resilient system for customers on New Providence. Just months into the project, one technology stands out: S&C’s IntelliRupter® fault interrupter. These intelligent devices are redefining outage prevention and restoration, and the early results are speaking volumes.

The Challenge of Reliability

New Providence, where the devices are installed, has long faced reliability challenges, with frequent outages disrupting homes and businesses. Traditional fault management methods often meant lengthy restoration times and widespread customer impact. BGC’s modernization strategy aimed to change that by introducing automation and intelligence at key locations across the grid’s distribution feeders.

IntelliRupter Fault Interrupters in Action

By July, BGC had deployed 47 IntelliRupter fault interrupters. These devices detect and isolate faults in real time, helping to prevent outages and minimize service interruptions. Just three months into the project, BGC saw:

• 182 potential outages avoided
• 170,000 service interruptions prevented
• 73% reduction in total outages compared to historical performance

6 Months of Progress

Fast forward to October and the results are even more impressive. The project is 28% ahead of schedule, with the IntelliRupter fault interrupters continuing to deliver measurable results:

• Outages for customers downstream of IntelliRupter fault interrupters were reduced by 86%.
• About 49,000 homes in historically outage-prone areas are now enjoying fewer interruptions.
• Integration with a new work management system enables remote operation and real-time response, accelerating restoration times.

Why It Matters

IntelliRupter fault interrupters aren’t just reducing outages; they’re transforming customer experience. Faster fault isolation and power restoration means fewer truck rolls, lower operational costs, and improved regulatory compliance. For BGC, this technology is more than an upgrade; it’s a foundation for a smarter, more resilient grid. Utilities worldwide can take note: Investing in smart technologies like S&C IntelliRupter fault interrupters isn’t just about preventing outages; it’s about building a grid that’s resilient to today’s-and tomorrow’s-challenges.
