Hybrid AC/DC Distribution: What's in It for Utilities

Description

This IDC Perspective discusses hybrid AC/DC distribution, which offers utilities a targeted solution to network constraints driven by the rise of DC-native loads, such as EVs, batteries, and datacenters. Rather than replacing AC, it introduces DC segments where they deliver efficiency, capacity, and resilience. "Early pilots show measurable savings," says Roberta Bigliani, group vice president, IDC. "But widespread adoption depends on advances in protection standards, workforce readiness, and regulatory frameworks. Utilities that engage early can shape system architecture and governance, while those that delay risk losing operational control."

Situation Overview

Why: The architectural case for utilities
- DC-native loads and sources cluster on specific feeders
- AC reinforcement runs into nontechnical limits
- Inverter-based resources reshape protection and stability
- Behind-the-meter DC is happening with or without DSO involvement
What: Hybrid architecture and reference deployments
- LVDC feeders inside the AC distribution
- MVDC corridors for capacity and controllability
- DC-coupled EV charging hubs
- Hybrid AC/DC microgrids for resilience and integration
- Behind-the-meter DC distribution as a planning factor
Who: Standards, programs, and the supply chain
- Standards bodies and alliances
- Research and demonstration programs
- Vendor categories DSOs will encounter
How: Where hybrid AC/DC fits, by utility profile
- Urban DSOs facing electrification at scale
- DSOs serving industrial and datacenter loads
- Rural and end-of-feeder DSOs
- DSOs in regions with strong sector coupling and storage
