Grain-oriented electrical steel (GOES)

The specially grown steel inside a large power transformer. Few mills can make it, and a new mill takes years.

    Amorphous metal transformer cores

    In production at scale, but only for part of the problem. ABB has sold amorphous metal distribution transformers for two decades; the constraint is applicability rather than maturity, because the lower saturation induction means a larger core cross-section, larger coils and a larger footprint — acceptable on a pole, not on a grid-scale unit.
