Hitachi Energy to accelerate introduction of HVDC

Hitachi Energy and Grid United, an independent electrical transmission company, have announced a collaboration to deliver high-voltage direct current (HVDC) technology for Grid United transmission projects that will interconnect the eastern and western regional power grids in the US. These projects will dramatically boost transmission capacity across the US to support the urgent need for smooth sharing of power between energy markets at a time of drastically increasing demand for electricity.

Long-distance transmission lines are critical in delivering low-cost energy from areas with access to abundant supply to areas with high demand. These projects will help overcome one of the most persistent bottlenecks in the energy transition in the US by bridging the east-west divide. They also will play an important role in supporting the US government’s commitment to accelerating the energy transition, and specific stated priorities of the US Department of Energy.

Under an innovative approach known as a capacity reservation agreement, Hitachi Energy will provide HVDC technology to support the development of multiple Grid United HVDC interconnections. These interconnections will help mitigate the impact of extreme events and accommodate the growing demand for electricity. The two companies are exploring potential projects to further strengthen the US electric grid.

This multi-contract framework, introduced by Hitachi Energy, is one of the first of new business models for the US. This new approach allows Hitachi Energy to plan in advance to increase manufacturing capacity, expand and train the workforce, and maximize standardization to increase efficiency between successive projects. Today’s announcement follows a similar approach taken with large utilities in Europe, and is a key innovation in securing the supply chain for the energy transition.
