Switched Source

Switched Source is an advanced grid technology company delivering medium-voltage power flow control solutions that expand the capabilities of modern distribution automation. The company’s flagship device, Phase-EQ™, is a first-of-its-kind distribution-level power flow controller that provides real-time, automated load balancing across phases on a circuit. As a grid-enhancing technology and a proven non-wires alternative, Phase-EQ gives electric utilities the ability to relieve capacity constraints, increase DER hosting capacity, support beneficial electrification, reduce losses, mitigate overload conditions, and improve system reliability without requiring large-scale infrastructure replacements. The device is engineered as a drop-in upgrade that is compatible with existing protection schemes and integrates seamlessly with SCADA, ADMS, and a wide range of feeder automation strategies. This approach allows utilities to deploy Phase-EQ at strategic points on the system and dynamically reshape power flows to optimize performance under changing operating conditions. Switched Source has worked closely with leading utilities, research organizations, and government innovation programs to validate the technology, including partnerships with ARPA-E, NYSERDA, EPRI, and other industry collaborators. These demonstrations have shown meaningful improvements in feeder flexibility, resilience, and operational value. With a focus on practical deployment, measurable economic benefits, and long-term asset value, Switched Source provides IOU, municipal, and cooperative utilities with a new class of field-ready tools that address challenges created by DER proliferation, electrification-driven load growth, evolving reliability requirements, and increasingly severe weather. The company’s mission is to help utilities build a smarter, more adaptive, and more resilient distribution grid that can meet the demands of the future while maximizing the performance of existing infrastructure.
