New Zealand North Island (EIPC cl 8.19(1)) — ride-through requirements

The FRT envelope a grid-scale battery must meet under New Zealand North Island (EIPC cl 8.19(1)) (New Zealand), digitized breakpoint by breakpoint and checked against the clause it came from.

Part of: the grid-code ride-through chart — compare this against 63 other standards in 42 countries.

What this is, and is not. A reading aid compiled from the clause cited below — not a compliance document. The primary text governs. Some values on this page are marked partial: the level is confirmed but at least one duration step could not be read directly from the source.

Breakpoints

Times are seconds from the start of the disturbance. Voltage is per-unit of nominal; frequency in hertz. An LVRT curve is a lower boundary (stay connected while voltage is on or above it), an HVRT curve an upper boundary, and FRT gives the band between its High and Low boundaries.

Event Duty Breakpoints Status
frequency ride-through (FRT) ride-through Low: 0.1s → 47 Hz; 0.101s → 47.1 Hz; 5s → 47.1 Hz; 5.001s → 47.3 Hz; 20s → 47.3 Hz; 20.001s → 47.5 Hz; 120s → 47.5 Hz partial

Where these values come from

  • FRT Electricity Industry Participation Code 2010, Part 8, cl 8.19(1)(a)-(f), cl 8.19(3), cl 8.21(1), cl 8.1B — verified verbatim in both the 1 May 2025 and 1 July 2026 consolidations. One boundary is a single level; no further duration steps digitized.
