As distributed solar PV adoption accelerates, utilities face mounting voltage volatility on distribution feeders, particularly at the grid edge. In response, Hawaiian Electric (HECO) has launched a series of pilot projects deploying voltage regulating distribution transformers (VRDTs) to extend hosting capacity without relying on traditional voltage regulation schemes or extensive infrastructure upgrades.

This session explores how VRDTs emerge as practical Grid Enhancing Technology (GET) that boosts local hosting capacity, provides dynamic voltage support, and offers a flexible, scalable solution to DER-induced challenges. Attendees will gain insights from HECO’s real-world deployment experience, including site selection, installation, control strategies, and early performance results. The presentation will also examine lessons learned, regulatory considerations, and how VRDTs integrate with advanced planning tools and control systems.

By blending field data with practical implementation insights, this session will equip utilities, engineers, and planners with a blueprint for applying VRDTs as part of a broader grid modernization and decarbonization strategy.
