Hitachi Energy is providing transformers made with low-carbon copper to TenneT Germany. This initiative is part of a broader supply chain decarbonization program aimed at reducing the embedded emissions of critical power grid infrastructure. By integrating lower-emission materials into the transmission grid, TenneT and Hitachi Energy are targeting the reduction of scope 3 emissions. This move highlights the growing importance of material science in achieving net-zero goals for energy utilities.

Low carbon copper is a start, but I want to see the actual percentage reduction in embodied carbon per unit. Is this a marginal gain or a significant shift in the manufacturing process?
The real question is whether TenneT is paying a premium for this. If procurement rules don't reward low carbon materials, these programs usually stay as small pilots rather than becoming the standard.
Hitachi is swapping standard copper for low carbon versions in TenneT's German grid. It is a decent move for supply chain cleaning, though the scale of the rollout isn't fully detailed here.
