Mitsubishi Electric Corporation has announced that it entered into a share transfer agreement on February 16 to wholly acquire Scibreak, a Swedish-based company that develops direct current circuit breakers (DCCBs).

The two firms aim to strengthen the competitiveness of their unified business by working closely on developing DCCB technologies for high-voltage direct current (HVDC) systems to support the increasing global deployment of renewable energy.

Purpose of Acquisition

The introduction of renewable energy generation, such as wind power, is increasing worldwide to achieve carbon neutrality. Particularly in offshore wind power generation, HVDC is used for long-distance transmission between offshore and onshore load centers, as it offers lower power losses and cost when compared to AC transmission.

In the future, multi-terminal HVDC networks are expected to develop

In the future, multi-terminal HVDC networks are expected to develop, particularly for offshore wind power generation in Europe, allowing for efficient cross-border energy transmission. These networks will require DCCBs, which will play a critical role in protecting the power system.

HVDC breakers will require very fast operation times

HVDC breakers will require very fast operation times, in the order of a few milliseconds, and companies are stepping up technological development in response to the need for more compact, high-performance, and cost effective DCCBs.

Scibreak has market-renowned DCCB technology, in terms of operation time and footprint. Through the acquisition of shares, Mitsubishi Electric will utilize Scibreak’s technology and know-how to lead the market commercialization of DCCBs, strengthening its global HVDC system business and contributing to the realization of carbon neutrality through the further spread of renewable energy.
