Modernizing the Grid: A Path to Enhanced Resilience
In today’s world, the reliability and resilience of our power grid is more important than ever. Richard Pinto, a senior project manager at United Illuminating (UI) with 40 years of experience, shares some insights about the significant efforts involved in modernizing a critical substation in Connecticut to ensure a stable power supply for our customers.

The Pequonnock Substation in Bridgeport faced unprecedented flooding during Hurricane Irene in 2011 and Superstorm Sandy in 2012, forcing complete shutdowns to protect the equipment and prevent catastrophic damage. Richard recalled the challenging decision to cut power, which left thousands of customers without electricity. These events highlighted a significant vulnerability in the grid’s infrastructure.
“We never had flooding issues there before,” Richard noted, emphasizing the impact of climate change. “Tides are up, and storms are a lot more severe than what they used to be.”
In response to the flooding, a comprehensive project was undertaken to relocate and elevate the Pequonnock Substation. The new facility, positioned 900 feet inland and five feet above the FEMA-defined 100-year flood level, showcases advanced engineering and resilience. The substation now employs high-voltage gas-insulated switchgear (GIS), a state-of-the-art technology housed within a building, offering enhanced protection against the elements.
Richard described the process: “We started this project with the goal of elevating and relocating the substation. The new structure is designed to withstand severe weather and rising tides, ensuring our equipment remains operational.”
Modernizing the grid is a complex task involving various efforts, from replacing aging infrastructure to implementing advanced technologies. Richard’s work focuses on high-voltage substations connecting to transmission lines that transport power regionally.
“Grid modernization isn’t just about addressing immediate issues like flooding; it’s also about upgrading aging infrastructure,” Richard explained. “We replace deteriorated poles, upgrade wires, and install larger conductors to meet current quality standards and ensure reliability.”
Key Components of the Modern Grid
The Pequonnock Substation project includes several key elements essential for a modern, resilient grid:
- Elevated and Relocated Infrastructure: Moving the substation inland and raising it above flood levels significantly reduces the risk of storm-related damage.
- Advanced Technology: High-voltage GIS within a protected building minimizes exposure to adverse weather conditions, enhancing operational reliability.
- Comprehensive Upgrades: Extensive work has been done to upgrade underground cables and other critical components, ensuring a robust power supply network.
Richard’s insights highlight the immense effort required to complete such projects. From navigating environmental regulations and securing permits to coordinating with municipalities and managing construction timelines, the path to modernization is challenging.
“It takes a lot of resources and engagement with different organizations,” Richard noted. “From conceptual design to final commissioning, a typical substation project can take six to eight years.”
Despite the timeline, the results are worth the wait. The new Pequonnock Substation is ready to face the challenges of a changing climate and increasing demand for electricity.
Investments in grid modernization are crucial for ensuring a reliable and resilient power supply. With the rise of electric vehicles and increasing reliance on electricity, the demand on the grid continues to grow. “Everyone wants their power,” Richard said. “It’s more essential now than ever before.”
By addressing vulnerabilities and upgrading infrastructure, projects like the Pequonnock Substation help safeguard against future disruptions, providing peace of mind for our community and customers.
Ensuring Reliability and Resilience for Today and Tomorrow
The modernization of the Pequonnock Substation is a testament to how proactive measures and innovative solutions can transform vulnerabilities into strengths, addressing the dual challenges of climate change and growing energy demands. For our customers, this means fewer disruptions, more reliable service, and the assurance that UI is committed to staying ahead of the curve. Projects like Pequonnock are crucial investments in our collective future, ensuring we all benefit from a stable and resilient power grid. Understanding the efforts and complexities involved helps us appreciate the vital role energy plays in our daily lives. The ongoing improvements at Pequonnock will significantly strengthen our transmission and distribution system, enabling us to consistently provide reliable service. As you flip the light switch or charge your electric vehicle, remember the dedicated work behind the scenes that makes it all possible.
