EconiQ® - Eco-efficient high-voltage portfolio

Hitachi Energy is collaborating with CHN Energy, a Chinese state-owned energy company, to reduce greenhouse gas emissions in their operations. Under this agreement, Hitachi Energy will provide its innovative EconiQ™ retrofill solution to replace SF6 gas in the existing 550-kilovolt (kV) gas-insulated lines (GIL) at the Zhejiang Beilun power plant in Ningbo, Zhejiang province, on the south-eastern coast of China.

Hitachi Energy will collaborate with Tirreno Power to install Italy’s first eco-efficient 420-kilovolt (kV) SF₆-free circuit-breaker. Manufactured in Italy, the groundbreaking equipment made at Hitachi Energy’s factory in Lodi is set to be installed in 2025. The move marks a significant step forward towards a sustainable electricity network in Italy.

Innovative EconiQ technology accelerates China's power grid decarbonization.

Innovative switchgear enables phaseout of SF6, a greenhouse gas 24,300 times more potent than CO2, staying in the atmosphere for over 1,000 years.

TenneT’s Maasbracht substation has the longest SF6-free gas-insulated line installation in Europe.

Hitachi Energy has booked orders for over 65 units of its groundbreaking EconiQ 420-kilovolt Dead Tank Breaker and the world is taking note.

Hitachi Energy and Linxon are collaborating to strengthen London Power Tunnels, a key power infrastructure project that will ensure reliable, clean electricity supply for England’s capital city.

On June 20, the breakthrough EconiQ dead tank breaker was delivered to Eversource during an exclusive event at Hitachi Energy’s state-of-the-art factory in Mount Pleasant, Pennsylvania, USA.

Reliable, scalable, and guaranteed to have the lowest carbon footprint: these significant features make EconiQ a standout SF₆-free solution in the industry.  

The agreement affirms the need to reduce F-gas emissions and ensures at the same time that high-voltage substations will remain safe, reliable, and compact.

Hitachi Energy is at the forefront of the energy transition with its  EconiQ™ high-voltage portfolio that eliminates SF₆ with reliable and scalable solutions for the lowest carbon footprint.

Hitachi Energy offers reliable SF₆-free high-voltage circuit-breakers with advanced switchgear technology to improve grid sustainability and increase the efficiency of the transmission system infrastructure.
