Ayr Energy launched a manufacturing and supply service that reintroduces iron-core electrical transformers, the century-old core technology used across power grids, featuring modular designs tailored to changing project needs. The startup was backed by investors including Energy Impact Partners and raised $25 million across two rounds while building an order book above $500 million.
Ayr contracted transformer makers in India to produce units to its specifications, prioritizing modularity so buyers can adjust orders later in development; customers include renewable developers, independent power producers and data-center builders. The firm positioned this approach amid a global surge in transformer demand driven partly by AI data centers and electrification trends.
For buyers facing long lead times and shifting project parameters, Ayr’s modular iron-core units reduced the risk of mis-sized equipment and sped procurement. The rollout signals renewed interest in legacy grid hardware as a practical response to supply shortages while leaving room to introduce next-generation solid-state options later.
