CASE STUDY

A dairy factory in the Azores stopped losing batches to voltage dips.

A dairy producer on Terceira, an island in the Portuguese Azores, was paying for the island's limited grid inertia. Dozens of short voltage dips a year were stopping critical equipment and ruining batches. Delays, extra labour, and rejected product added up to roughly €100,000 in annual losses.

Teraloop installed a 100 kW flywheel inline at the factory in April 2024. It runs 24/7, catching sub-200 millisecond voltage dips before production stops and injecting fast frequency reserve when the island's grid drifts off 50 Hz. Verified response at the connection point: 15 milliseconds.

INSIDE THE FULL CASE STUDY

  • Why island grids cause voltage dips and what they cost a process line

  • The single-line diagram and where the flywheel sits in it

  • Measured response data from the first 18 months of operation

  • What it cost, how it was financed, and what the payback period looked like
