EECA (Energy Efficiency and Conservation Authority). Consumer Energy Monitor Q3 FY25. Released June 2025. Quarterly online survey of NZ adults aged 18+. Q3 FY25 fieldwork: 19 January 2025 – 22 March 2025. n=758 (this quarter), n=2,308 (FY25 cumulative across Q1+Q2+Q3 ending March 2025). Margin of error ±3.8% at 95% CI for the single quarter. Nationally representative by age, gender and region.

Scope and structure
- 18-page slide deck (cover + Background + Methodology + Executive Summary + “This report” + 8-action savings table + 2 awareness/uptake slides + 4 sub-group analysis chapter (2 slides per sub-group × 4 sub-groups) + closing slide)
- Quantitative behavioural data on 8 named energy efficiency actions
- Off-peak pricing plan penetration + appliance-level off-peak shifting
- 4 pre-identified sub-groups with significance-marked differences vs total population
Relevance to NI and thesis
NI (residential demand-side parameters):
- The 8-action savings table (key_claim 2) is the canonical NZ-government quantification of household efficiency potential — feeds the NI energy skill’s pre-vs-post-efficiency household load assumptions
- Off-peak plan penetration (32%) + appliance-level shifting rates (key_claim 7) feed realistic DR participation modelling for PV+BESS sizing — avoid assuming higher off-peak shifting than the 9% always-doing rate without justification
- Heat-pump filter cleaning rate (18% always doing) is a discovery: NI heat-pump efficiency assumptions should include filter-fouling derating for ~80% of households
- Sub-group cuts (especially cold-homes + non-homeowners) inform NI sensitivity bands for Lower Moutere if pilot demographics tilt that way
Thesis (behavioural / community-design argument):
- Counter-intuitive finding (key_claim 8) — higher bills correlate with lower efficiency behaviour — anchors the argument that financial signal alone does not drive efficient action; community-scale governance / coordination / collective infrastructure are required
- Non-homeowner under-investment (key_claim 11) is direct evidence for the landlord-tenant split-incentive problem at NZ national scale — supports the community-housing-model argument that ownership structure shapes investment behaviour
- Households with children pattern (key_claim 10) — high engagement with financial mechanisms, lower behavioural action — supports time-poverty as a structural determinant of efficiency uptake
Cross-validation with RD_007:
- Bundled savings potential ~2,595 kWh / hh / yr (OT_026) vs ~6,790 kWh/hh/yr current residential electricity (RD_007) = ~38% theoretical electricity reduction ceiling if every household adopts every action. This is the upper-bound for the demand-side argument; realistic uptake will be a fraction of this.
- Hot water cylinder appears in both: RD_007 confirms it’s 27% of residential electricity; OT_026 confirms only 26% of off-peak users actually shift it — material untapped shifting potential.
Research targets
Documents to retrieve
- RT_128 (medium) — EECA Consumer Energy Monitor Q4 FY25 + future quarters. Quarterly cumulative series; FY26 sample will refresh the sub-group percentages. Monitor at eeca.govt.nz/insights/.
- RT_129 (low) — Underlying microdata access. EECA may release SPSS / Stata / CSV microdata via direct request; would enable Tasman / Nelson-Marlborough regional sub-cut not present in the published deck. Worth requesting only if the regional cut becomes load-bearing for NI.
