New Zealand sets 10 kW default export limit for rooftop solar
Why it matters: 75,000 NZ homes with solar can export up to 10 kW, lowering reliance on higher‑cost grid power.
- Electricity Authority Te Mana Hiko updates connection rules, mandating a 10 kW default export for small‑scale distributed generation like household solar and batteries.
- Line companies can voluntarily raise limits and now may offer dynamic or flexible export caps, adjusting to network conditions.
- Assessment tools will be required for larger distributed generation (>10 kW) to standardize limits across 29 network operators, supporting future tech like vehicle‑to‑grid.
New Zealand’s Electricity Authority has set a 10 kW default export limit for rooftop solar and battery systems, while allowing utilities to use dynamic caps and requiring assessment tools for larger distributed generation, all to boost low‑cost renewable feed‑in and cut consumer bills.
