Daqo Showcases SF6-Free Power Solutions for Europe's Energy Transition


07/01/2026


As Europe rapidly expands renewable energy capacity, energy storage systems, and electrification initiatives, project developers are under increasing pressure to accelerate grid connections for new power generation assets and energy-intensive facilities while complying with more demanding standards for sustainability, reliability, and project execution.

One of the key technologies showcased by Daqo was the DQS Air Series SF6-free ring main unit (RMU). Utilizing dry-air insulation combined with vacuum interruption technology, the DQS Air system offers an environmentally responsible alternative to traditional SF6-based medium-voltage equipment. Its compact and fully sealed construction is designed to minimize maintenance requirements while ensuring dependable performance across urban power networks, renewable energy installations, industrial applications, and grid modernization projects.

Daqo also unveiled its newest SF6-free air-insulated RMU solution developed for secondary distribution networks. Engineered with flexible configuration options, intelligent monitoring capabilities, and remote operation readiness, the system is intended to help customers build more sustainable, efficient, and easier-to-manage power distribution infrastructure.

For renewable energy and battery storage applications, the company presented its containerized photovoltaic (PV) and battery energy storage system (BESS) substation solutions. These integrated systems combine step-up transformers, medium- and low-voltage switchgear, monitoring platforms, and auxiliary equipment within a factory-assembled unit. This approach enables developers and EPC contractors to reduce on-site complexity, streamline project coordination, and accelerate the timeline from installation to grid connection.

Addressing the requirements of power-intensive industries such as data centers, Daqo showcased DQMpower 2.0, a modular power platform that consolidates low-voltage distribution, UPS-related functionality, power quality management, and monitoring systems. The solution is designed to improve deployment speed, maximize the utilization of electrical room space, and provide greater operational transparency. The company's solid-state transformer technology also attracted attention as an advanced solution capable of supporting more flexible interaction between electrical grids, energy storage systems, loads, and DC power networks.

"Our discussions with customers at The smarter E Europe reinforced a clear industry priority: energy infrastructure projects require cleaner technologies, faster grid access, and more predictable project delivery," said Kevin Lin, General Manager for Daqo's European region. "Daqo continues to expand its European coordination capabilities and partner ecosystem to provide customers with integrated technical solutions, simplified project interfaces, and enhanced delivery support."

Daqo's strategy in Europe centers on combining large-scale manufacturing capabilities with localized coordination and partner collaboration. The company operates through a network of 32 manufacturing entities, providing expertise across medium- and low-voltage electrical equipment, transformers, automation technologies, and integrated power systems.

For European customers, this approach offers streamlined technical solutions, reduced supplier complexity, and improved control over project delivery. Moving forward, Daqo plans to deepen collaboration with utilities, developers, EPC contractors, and industrial clients to advance the deployment of cleaner, more reliable, and rapidly deployable power infrastructure throughout Europe.
