New Zealand (EIPC cl 8.25A) — ride-through requirements

The HVRT envelope a grid-scale battery must meet under New Zealand (EIPC cl 8.25A) (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. Every value here was read from a current primary 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
high-voltage ride-through (HVRT) ride-through 0.001s → 1.2 pu; 2s → 1.2 pu; 2.001s → 1.15 pu; 6s → 1.15 pu; 6.001s → 1.1 pu verified

Where these values come from

  • HVRT Electricity Industry Participation Code 2010, Part 8, cl 8.25A(1) and (6), upper boundary of Figure 8.1 / Figure 8.2 — verified in the 1 May 2025 consolidation; clause unchanged at 1 July 2026.
