GE Vernova to Supply SF₆-Free Grid Hubs for Berlin’s Power Network
- GE Vernova secures dual contracts from Stromnetz Berlin to deploy 110 kV gas-insulated substations in Wittenau and Neukölln districts
- The new substations will feature GE Vernova’s eco-conscious g³ technology—free of SF₆—and part of the company’s GRiDEATM suite aimed at advancing low-carbon power transmission
- Projects align with Stromnetz Berlin’s mission to upgrade vital grid infrastructure, reinforcing reliability across one of Europe’s most extensive urban switchgear networks
BERLIN, Germany, (16 July 2026): GE Vernova Inc. (NYSE: GEV) has been selected by Stromnetz Berlin GmbH to engineer, supply, and install two high-voltage substations in Wittenau and Neukölln. These installations will serve as critical junctions within Berlin’s electricity grid, distributing power to multiple local substations that energize homes, commercial facilities, and public services throughout the capital.
The 110 kV gas-insulated substations will utilize GE Vernova’s SF₆-free g³ insulation technology, replacing sulfur hexafluoride (SF₆), a powerful greenhouse gas commonly used in high-voltage electrical systems for insulation and arc suppression. The g³ alternative delivers equivalent performance and space efficiency while cutting the global warming potential of the insulating medium by approximately 99% compared to traditional SF₆-based solutions.
“Modernizing Europe’s power grids demands technologies that balance operational dependability, environmental responsibility, and rapid deployment,” said Frank Ennenbach, Central Europe Regional Leader for GE Vernova’s Grid Systems Integration division. “By implementing g³ in these urban substations, we’re demonstrating how scalable, SF₆-free solutions can meet the rigorous demands of densely populated cities where space constraints, timing, and system resilience are paramount. As Europe scales up its grid investments, utilities need flexible options that lower carbon impact without compromising real-world functionality. We’re honored to support Stromnetz Berlin in advancing Berlin’s energy future.”
“Stromnetz Berlin operates one of the continent’s largest urban gas-insulated switchgear networks, playing a key role in ensuring stable electricity delivery for the city,” noted Elena Brauns, head of resources and environment at Stromnetz Berlin GmbH. “With the Wittenau and Neukölln projects, we’re upgrading our infrastructure to enhance both supply security and climate performance. GE Vernova’s g³ technology supports our commitment to modernizing the grid using high-voltage equipment with a significantly reduced environmental footprint.”
As urban centers increase electrification in transport, heating, buildings, and industrial processes, robust and efficient grid infrastructure becomes essential for economic vitality and everyday living standards. In compact city environments, where available space is limited and network stability is non-negotiable, compact, durable, and low-emission high-voltage substations offer strategic advantages.
g³ technology is a core component of GE Vernova’s GRiDEATM portfolio, a range of innovations designed to drive decarbonization in power transmission. This portfolio encompasses not only SF₆-free high-voltage equipment but also solutions focused on minimizing raw material usage, extending asset lifecycles, and enhancing overall grid efficiency.
With over a century of presence in Germany, GE Vernova plays a pivotal role in supporting the nation’s goal of achieving net-zero emissions by 2045. Today, around 30% of Germany’s electricity generation relies on GE Vernova technology. The company contributes to the country’s energy transformation through major generation initiatives, electrification programs, grid resilience solutions, large-scale transmission developments, and wind turbine manufacturing at its Salzbergen production site.
The Wittenau project is scheduled to run from June 2026 to March 2031, while the Neukölln installation will extend from June 2026 to January 2032. The contract was recorded in April 2026. Specific financial terms remain undisclosed.
