When Cyclone Gabrielle cut power to large parts of Te Tairāwhiti, Tararua, and Hawke’s Bay in 2023, communities discovered something — the buildings that recovered fastest had solar panels and batteries on the roof. Three years on, New Zealand is quietly funding the largest rollout of community microgrids in its history. Marae, schools, halls, and iwi-led energy companies are at the centre of it.

If your marae, kura, community hall, or iwi-owned organisation is weighing energy independence, the 2026 funding landscape is dramatically better than two years ago. Below is what is actually being built, who is paying for it, and how communities are designing systems that hold up beyond the next cyclone. For a technical view of what sits inside any community installation, our battery solutions overview covers the components.

What a community microgrid actually is

A microgrid is a small electricity network that can run independently from the main grid when it needs to. Not just solar panels with a backup battery — it is the combination of generation, storage, and control systems that lets a community stay powered when everything around them is dark.

• The three building blocks: renewable generation (usually solar PV), battery energy storage, and control electronics that decide when to use grid power, when to use stored power, and when to disconnect.
• What makes it “community”: the system serves shared facilities — a marae, a school, a hall — rather than a single household. Many can share power with surrounding homes or sell surplus back to the grid.
• “Islanding” is the key capability: the ability to disconnect from the main grid during an outage and keep operating on stored solar power. Without islanding, a system is just a UPS.

The EECA Community Renewable Energy Fund

The biggest single driver of NZ community microgrid deployment in 2025–2026 is the Community Renewable Energy Fund, administered by EECA (Te Tari Tiaki Pūngao) in partnership with MBIE.

• The numbers: by end of 2025, an estimated 217 community resilience sites will have been selected to receive solar PV and battery systems. Average cost per site is $88,000.
• Average system size: 28 kW solar PV and 32 kWh battery storage — meaningful for a marae or school, not utility scale.
• Eligible buildings: marae, places of worship, schools, and community halls. Selection is co-managed with Civil Defence, local authorities, and Māori organisations.
• Cyclone Gabrielle recovery and 2025 rollout: 67 sites in flood and cyclone-affected regions are being selected first, with 2025 rollout regions including Northland, Tairāwhiti, Hawke’s Bay, Tararua, Wairarapa, Waikato, Bay of Plenty, Marlborough, Nelson, Tasman, and West Coast.

Tau Henare Marae — the largest marae-based microgrid in NZ

The most ambitious community-scale microgrid in New Zealand right now is the Tau Henare Marae project at remote Pipiwai in Northland, delivered by iwi-owned Tū Mai Rā Energy.

• Scope: the largest marae-based solar and battery network in the country, with capacity to extend cheaper power to neighbouring homes — effectively a community utility built around the marae.
• Funding source: the MBIE Māori and Public Housing Renewable Energy Fund — a separate funding stream specifically designed to support energy independence for Māori communities.
• The operator: Tū Mai Rā Energy is an iwi-owned business that emerged from the Rangitāne Waitangi Tribunal settlement for lower North Island iwi. Energy independence sits inside iwi economic development strategy.
• The promise to whānau: the marae chair has publicly indicated the project aims to roughly halve household power bills for surrounding community members — direct cost relief in addition to grid independence, and proof that iwi-led community microgrids can deliver both resilience and lower bills.

Energy trading between marae and homes — the Our Energy model

One NZ tribal community microgrid has gone further than emergency resilience — building a working energy-trading marketplace between the marae and surrounding households.

• The configuration: solar PV on five properties (three serving families living on ancestral Māori land), plus a 120 kWh community battery next to the marae itself.
• How it trades: excess solar from the largest array charges the community battery, which then sells stored power to participating whānau at below-retail rates.
• The price point: surplus solar has been sold to vulnerable households at NZ$0.06 per kWh — approximately 18% of standard retail electricity prices.
• The pool model and retention purpose: when no trades happen, surplus generation goes into a community “pool” for later distribution. A central goal is to reduce living costs in ways that help tribal members remain on ancestral land — energy independence as an enabler of cultural continuity.

Council-led models — the Kāpiti Coast example

Local councils are increasingly co-funding community resilience installations alongside EECA, creating a parallel funding pathway for buildings not on the EECA priority list.

• The Kāpiti programme (announced December 2025): up to eight community buildings to receive solar and battery systems by July 2026.
• The funding split: EECA contributing up to $500,000, Kāpiti Coast District Council investing $167,000. Council owns and maintains the systems.
• Target buildings: a mix of marae, schools, and halls across the district, prioritised in consultation with WREMO.
• The dual benefit: previous EECA recipients have reported lower monthly power bills for community facilities in regular use — resilience and operating cost reduction in one investment.

Where vanadium flow batteries fit in the next wave

The 217 EECA-funded sites currently being deployed largely use lithium-ion — the mature, donor-fund-friendly choice for the first wave. The second wave will increasingly look at flow chemistry for specific reasons.

• Cycle life over decades: a community microgrid is a 25-year decision. Vanadium flow delivers 25,000+ cycles vs lithium’s typical 5,000–7,000 — the 2026 system stays at full capacity into the 2040s.
• Fire safety in community buildings: a marae is a meeting house, not a battery shed. Vanadium electrolyte is non-flammable and cannot thermally run away — meaningful when the battery sits adjacent to buildings where people sleep.
• Maintenance for remote sites: remote marae and rural schools cannot easily call out technicians. Flow batteries have simpler service profiles and tolerate sitting at any state of charge indefinitely.
• Scaling duration cheaply: if a community wants 8 or 12 hours instead of 4, scaling vanadium means adding electrolyte to the existing tank — far cheaper than adding more lithium cells. For larger marae complexes or multi-building campuses, the UPower Series is sized for community-scale loads.

Conclusion

Community microgrids have shifted from concept to deployment in New Zealand. EECA’s 217-site rollout, the Tau Henare Marae project, Tū Mai Rā Energy, the Our Energy trading model, and council co-funding programmes like Kāpiti’s all point in the same direction — communities that own their generation and storage hold up better through climate events, cost less to run, and increasingly keep more of the value at home. The first wave is mostly lithium and grant-funded. The second wave will look further out, and that is where flow chemistry earns its place.
