CR_054: NZ micro-hydro distance CapEx + V2H charger + district-heat connection + legume protein + small-wind CF…

NZ micro-hydro distance CapEx + V2H charger + district-heat connection + legume protein + small-wind CF (July-2026 figures synthesis)

Parent synthesis behind five already-resolved targets — RT_286 / RT_287 / RT_288 / RT_289 / RT_290. Does NOT reopen them.

AI-compiled, medium. This is the original July-2026 research draft from which RT_286–290’s figures were extracted; each figure has since been ingested via its own verified primary — micro-hydro penstock/cable URL_018/URL_019, V2H URL_020, district-heat OT_089/URL_021, faba protein OT_088, small-wind method/turbines URL_017/DS_001/DS_002. All five RTs are already in ## Done. No figure is applied to a model cell on this page’s authority — the applyable numbers already landed via those primaries. CR_054’s value is the cross-cutting layer no single primary carries: the combined penstock distance term ~25–50/m**, the district-heat **marginal-vs-full-fit-out boundary (NZ3.5–35k/home), the Rayleigh k=2 → CF = AEO/(rated×8760) method, and a per-figure confidence map. context: ni — provenance + triangulation, not a new cell.

Summary

A five-topic NZ cost/technical synthesis prepared for the NEOBIOME model (July 2026), each topic mapped to a research target. (RT_286) Micro-hydro distance CapEx: no NZ vendor publishes a bundled hydro /m, so the distance term is built from components — PE100 penstock **6.8–11.2/m** (50–63 mm, verified NZ retail), LV cable 8.3/m (6 mm²) → 21.7/m (25 mm²) (verified NZ retail), trenching ~90–120/m** (medium) → a combined distance term **~25–50/m for a small scheme, rising with pipe diameter. (RT_287) V2H / bidirectional charger: best NZ-quoted hardware ≈ NZ15,000** (2022 Wallbox Quasar importer estimate, since discontinued — order-of-magnitude only) + electrician install; true V2H/V2G limited to a small handful of models, EECA's approved list carries **one** two-way charger. **(RT_288) District-heat connection:** no single NZ number — a build-up of verified NZ in-home hydronic fit-out **NZ18–30k/home + UK-derived buried DH pipe ~£1,000/m ≈ NZ2,200/m** + HIU **~£1,075/dwelling ≈ NZ2,300 → marginal (service+HIU) ~NZ3.5–5k/home** vs full-fit-out **~NZ18–30k/home. (RT_289) NZ legume/pulse protein: faba beans are the protein/ha champion — surveyed mean 5.6 t/ha × 27.7–31.1% protein → ~1,550–1,740 kg protein/ha (verified NZ, FAR); peas ~0.7 t protein/ha; lupins lower. (RT_290) Small-wind power curve + m/s→CF: Bergey Excel 10 datasheet (rated 8.9 kW @ 11 m/s) + the universal US-DOE method — Rayleigh (Weibull k=2.0) power-curve integration, CF = AEO ÷ (rated kW × 8,760), quick rule AEO ≈ 0.01328·D²·V³; small-wind CFs ~10–25%.

Key claims

- claim: "MICRO-HYDRO DISTANCE CapEx — NZ $/m component build-up (RT_286; RESOLVED → URL_018 + URL_019). No NZ hydro vendor publishes a bundled per-metre install cost, so the distance term is built from components. PENSTOCK (PE100 pressure pipe, VERIFIED NZ retail): 50 mm 12.5-bar $6.83–8.06/m ('50m roll: NZD $403.00' / '100m roll: NZD $754.00'), 63 mm $9.75–11.18/m ('50m roll: NZD $559.00' / '200m roll: NZD $1,950.00') — Rural Water NZ, 'PE100 polyethylene to AS/NZS 4130' (→ URL_018). LV CABLE (VERIFIED NZ retail): 6 mm² 2-core+earth TPS $8.34/m inc GST (Electrical Direct); 25 mm² 2-core buried-grade XLPE mains $21.74/m inc GST (Lighting & Electrical Supplies) — pick by current/voltage-drop (→ URL_019). TRENCHING (MEDIUM — NZ contractor blogs, not a rate card): ~$90–120/m basic, $100–250/m deeper/harder ground. COMBINED distance term ≈ $25–50/m for a small scheme (small pipe + small cable + shared trench), scaling with pipe diameter/depth. ⚠ PowerSpout (NZ turbine maker) publishes ONLY kit prices ('Basic DIY Turbine Kit $1,599.00 NZD'), no per-metre trenching/cable schedule → the distance term must be built from components, not a vendor bundle. Pipe diameter is set by flow/head-loss (velocity 2.5–3.5 m/s, head loss 5–10% of gross head) → treat $/m as diameter-dependent, not a constant. Trenching is the softest, most site-variable number."

- claim: "V2H / BIDIRECTIONAL EV CHARGER — NZ cost + fleet share (RT_287; RESOLVED → URL_020). (a) INSTALLED COST (HIGH but DATED): best NZ-quoted figure ≈ NZ$15,000 for the hardware (Wallbox Quasar), install extra (registered electrician) — Mitsubishi Motors NZ / Ingham Driven 'V2H FAQs' (Jul 2022): 'Wallbox Quasar is expected to retail for approx. NZ$15,000 subject to exchange rate and shipping costs', 'requires a registered electrician to wire up'. For a planning number use NZ$10,000–15,000 hardware + install. Intl anchor: Wallbox Quasar 2 from US$6,440 ex-tax/install (≈ NZ$10.8k hardware). (b) FLEET/MODEL SHARE (MEDIUM/INTERIM — no published NZ %): true V2H/V2G capability limited to a small handful of models on sale (Nissan Leaf, Mitsubishi Outlander/Eclipse Cross PHEV, Kia EV9, Cupra Born, VW ID.3/ID.4 — EVDB.nz); most NZ EVs are V2L-only. EECA approved list contains ONE two-way charger (StarCharge 'AD20074EU1923'); 'EECA has not assessed or endorsed the bi-directional (V2X) functionality of these chargers at this time'. EECA Queenstown trial: 'an initial tranche of fewer than 10 two-way chargers … expand … to around 30–40 chargers … during 2026'. ⚠ The NZ$15,000 is a 2022 importer estimate and the original Quasar was later DISCONTINUED — dates the order of magnitude, not a live 2026 price. ⚠ Nuance: the Nissan Leaf (CHAdeMO), historically a large share of NZ's used-import EV fleet, is technically V2H-capable via a CHAdeMO bidirectional unit → the technically-capable fleet share exceeds the model-on-sale share."

- claim: "COMMUNITY DISTRICT-HEAT CONNECTION — build-up, no single NZ number (RT_288; RESOLVED → OT_089 + URL_021). PER-HOME IN-HOME HYDRONIC FIT-OUT (VERIFIED NZ retail): NZ$18,000–30,000/home — Modserve 'Central Heating Costs in NZ' (2026): 'Hydronic Radiator Systems: Typically $18,000–$30,000, depending on the number of radiators, boiler choice, and property size' (→ URL_021); this is a WHOLE in-home hydronic system = upper bound on a per-home connection for a home not already hydronic.

- claim: "NZ LEGUME / PULSE PROTEIN — yield × protein → kg protein/ha (RT_289; RESOLVED → OT_088). FABA BEANS (Vicia faba) — protein/ha champion, VERIFIED NZ: surveyed mean yield 5.6 t/ha (range 1–8.5; 'Crops grown in New Zealand have yielded between 1 and 9 t/ha'); protein 'spring cultivar … 27.7%' / 'winter cultivar had the higher average protein content at 31.1%' (Canterbury 2009–2011) → edible protein ≈ 5.6 × 0.28–0.31 ≈ 1.55–1.74 t/ha (~1,550–1,740 kg protein/ha) at mean yield — FAR Focus 8, Issue 08 (Dec 2012), grep-verified verbatim (→ OT_088).

Each RT_286–290 figure has been individually retrieved and ingested as its own source (all already in ## Done):

Neobiome Intelligence relevance

CR_054 is the provenance + triangulation umbrella for the RT_286–290 figure set. Every applyable number already landed on the domain pages via its verified primary (above); CR_054 does not re-apply them — it records where the bundle came from, the cross-source integration no single primary carries, and the per-figure confidence map. Per the cr_ verified-source-only rule, nothing hardens on this AI-compiled page’s authority.

  • RT_286 (D26, micro-hydro distance CapEx) — the combined distance term. The single-figure value CR_054 adds beyond URL_018/URL_019 is the **~25–50/m combined distance term** (small pipe + small cable + shared trench) and the caveat that it is **diameter-dependent, not a constant**. At ingest the engine's penstock rate was firmed from URL_018 (8–13/m PE100) + the corpus trench proxies (CR_037/CR_027, later the NZTA-accepted OT_113 via RT_292) → live ~$110/m trench-dominated; LV cable (URL_019) was excluded as double-counting reticulation. Feeds D01 / micro_hydro. No new cell.
  • RT_288 (F14, district-heat connection) — the marginal-vs-full boundary. CR_054’s cross-cutting contribution is the explicit boundary split: marginal connection (service pipe + HIU) ~NZ3.5–5k/home vs full in-home hydronic fit-out ~NZ18–30k/home → true per-home NZ$3.5–35k, folded into biomass_district_heating. Verified NZ in-home hydronic (URL_021) + UK-derived network/HIU (OT_089); no NZ scheme cost exists → real one = RT_294. Feeds D01. No new cell.
  • RT_290 (R12, small-wind CF) — the method summary. CR_054 records the Rayleigh k=2 → CF = AEO/(rated×8,760) method and the AEO ≈ 0.01328·D²·V³ rule of thumb (both from URL_017), plus worked CF examples (~10–25%). ⚠ its illustrative turbine (uncertified Bergey Excel 10) was superseded at ingest by the certified Excel 15 (DS_002) + NZ Thinair 102 (DS_001); the method is identical. Feeds D01 / wind_turbine. No new cell.
  • RT_287 (D27, V2H charger) — cost order-of-magnitude + fleet nuance. Already fully applied on D05 via URL_020 (DC ~NZ12–15k / AC ~NZ3–5k, IEA-anchored; one approved two-way charger). CR_054 adds the NZ$15k 2022 Quasar order-of-magnitude anchor (now discontinued) and the Leaf-CHAdeMO technically-capable > model-on-sale nuance. Feeds D05. No new cell; real numbers = RT_293 (late 2027).
  • RT_289 (D29, plant protein) — faba anchor + pulse spread. Already applied on D02 via OT_088 (faba ~1,550 kg protein/ha, lifting LEGUME_PROTEIN_KG_HA 900 → ~1,500). CR_054 adds the pulse spread placing faba as the upper-realistic value (peas ~0.7 t protein/ha, lupins lower) → confirms the constant stays conservative; field-pea/lupin primary = RT_291. Feeds D02. No new cell.

Retrieval provenance

  • Upstream source: the NZ/UK/US primaries listed under Underlying sources (Rural Water NZ; Electrical Direct + L&E Supplies; PowerSpout; Ingham Driven/MMNZ + EECA + Rewiring Aotearoa + EVDB.nz; Modserve; DECC/AECOM 2015; FAR Focus 8 2012; Bergey Excel 10 2013 + US DOE WINDExchange).
  • Prepared by: AI-compiled research synthesis for the NEOBIOME project (exact tool unconfirmed) on 2026-07-06.
  • Prompt: research the five RT_286–290 NZ cost/technical figures (micro-hydro distance $/m; V2H bidirectional-charger cost + fleet share; community district-heat connection cost; NZ legume/pulse yield × protein → kg protein/ha; small-wind power curve + m/s→capacity-factor method), tagging a figure “verified” only where the source page/PDF was opened and the exact number confirmed (quote + URL), else high/medium.
  • Verification: AI-extracted with per-figure tags; the “verified”-tagged figures (penstock, cable, NZ hydronic, faba, Bergey datasheet, DOE method) were opened-and-confirmed by the synthesis and have since been re-verified at primary ingest (URL_018/019/021, OT_088, DS_002, URL_017). Trenching, the combined distance term, the V2H fleet-share %, and the UK network/HIU figures remain medium/interim. Treat this page as medium — provenance + triangulation, not an applyable cell.

Research targets

CR_054 raises no new RT numbers — RT_286–290 are already RESOLVED (each → its primary, in ## Done). The live follow-ons that this synthesis motivated already exist:

Documents to retrieve (already open — not re-raised)

  • RT_291 — NZ field-pea + lupin yield × protein primary, to complete the pulse picture beyond the faba-only anchor (peas ~0.7 t protein/ha; faba the champion ~1,550–1,740). → D02 / RT_289
  • RT_293 — real published NZ V2H numbers once they exist: post-Queenstown-trial retail/installed bidirectional-charger price + a V2H-capable fleet-share figure from the EECA two-way trial final report (expected late 2027). → D01/D05 / RT_287
  • RT_294 — a real NZ community/campus district-heat scheme costing (per-connection / network $/m) to replace the UK-derived OT_089 network+HIU figures + fix the housing boundary. → D01 / RT_288

Research gaps

  • The RT_286 trenching rate residual was closed by RT_292 → OT_113 (NZTA-accepted civil rates). The combined distance term, the V2H fleet-share %, and the district-heat build-up remain medium/interim pending RT_291/293/294.

Notes

AI-compiled July-2026 research draft, data_quality: medium. This page is the parent synthesis behind nine already-ingested primaries (URL_017–021, DS_001, DS_002, OT_088, OT_089); it is filed for provenance and cross-cutting triangulation, not to re-apply figures — every applyable number already landed via its verified primary, and RT_286–290 are already in ## Done. Per the cr_ verified-source-only rule, no model cell hardens on this page’s authority.

Ingest deltas worth carrying (where the corpus already diverged from this draft): (1) RT_286 LV cable (URL_019) was excluded from the hydro distance term at ingest as double-counting electrical reticulation; the live penstock rate is trench-dominated ~110/m (URL_018 + OT_113/CR_037/CR_027), not this draft's 25–50/m combined term. (2) RT_290 was resolved with the certified Bergey Excel 15 (DS_002) + NZ Thinair 102 (DS_001) rather than this draft’s uncertified Bergey Excel 10; the DOE method (URL_017) is unchanged. (3) RT_287 D27 charger CapEx/fleet-share on D05 are IEA-anchored (OT_024) estimates, not this draft’s single NZ$15k figure.
