What Top Energy does

Top Energy is a consumer trust-owned electricity lines company and power generator serving New Zealand's Far North region. The company operates a regulated distribution network of over 4,000 km connecting approximately 34,000-34,500 residential and commercial consumers, making it the exclusive network provider in its geographic catchment. Its wholly-owned subsidiary, Ngāwhā Generation, operates a multi-unit geothermal power station (OEC3, OEC4, NG9) producing 423.4 GWh annually, with capacity to operate in 'Island Mode' and independently power the Far North during national grid emergencies. The company also provides rooftop solar connection services, fault reporting, and an outage centre platform (outages.topenergy.co.nz) with real-time notification capabilities. Underlying technology includes low-voltage network monitoring, smart meter data integration, and tools for managing two-way energy flows as distributed solar generation grows (currently 2,281 solar-connected households, >5% of total connections).

Top Energy's business model is built on regulated network revenue, recovered through approximately 20 electricity retailers (Contact, Genesis, Mercury, Meridian, Nova, Trustpower, Prime) who pass lines charges through to end consumers. Network revenue is reset every five years under Electricity Authority oversight (most recently April 2025), and from April 2025 customers see annual lines charge increases of approximately $156/year. The company also earns generation revenue from wholesale electricity sales (sensitive to wholesale prices) and one-time connection fees ($100 application fees plus $1,000-$10,000 connection costs). Customer segments are vertical: Far North residential consumers (primary, ~34,000+ connections, average household use ~5,500 units/year vs national ~8,000), commercial/industrial customers requiring new or upgraded connections, and solar/renewable prosumers (export limits recently raised to 10kW from April 2026).

Ownership by the Top Energy Consumer Trust — established in 1993 and representing ~34,500 beneficiaries — is structurally distinctive: profits are returned to consumers via annual discounts of up to $200/connection rather than paid to shareholders. The company has invested $170 million in the network over the past decade (lifting asset value from $128M to $250M), with a further $350 million planned over the next decade, and has converted 100% of lending facilities to certified Green Loans. Revenue grew 12.1% to approximately $114M in FY2024/2025 and a further 6.4% in FY2025/2026, with EBITDAF running 5-10% above prior year. Headcount stands at 197, supported by active trainee and graduate hiring programmes.

Revenue model

1. Network Revenue: Regulated lines revenue from electricity distribution. Revenue increased 15.3% ($7.3 million) driven by the 2025-2030 regulatory reset, Transpower increases and small increase in overall consumption. This is the primary revenue stream, recovering the cost of maintaining and operating the electricity network.
2. Ngāwhā Generation Revenue: Electricity sales from the Ngāwhā geothermal power station. Generation output was 423.4 GWh in 2025/2026. Revenue is sensitive to wholesale electricity prices, with generation revenue down 2.9% ($1.5 million) in 2025/2026 due to lower average wholesale prices.
3. Network Connection Services: Fees for new connections to the network, including application fees (~$100) and connection costs ranging from $1,000 to $10,000 depending on requirements. Distributed generation applications (solar) also generate connection revenue.

Direct peers

• Northpower: New Zealand electricity lines company serving the Whangarei and Kaipara regions, with both distribution and generation (Ngāwhā Generation co-sponsor). Closest geographic and business-model peer to Top Energy - both are regional NZ EDBs operating regulated networks and generation in Northland.
• Vector Limited: New Zealand's largest electricity distributor, serving Auckland. Comparable EDB line-company business model with regulated network revenue, scale operating leverage, and asset-growth capex programmes.
• Powerco: NZ EDB serving the Taranaki, Manawatu, Whanganui and Wellington regions. Direct peer in regulated electricity distribution with multi-regional network footprint and ongoing capex programmes.
• Wellington Electricity: Lines company owning and operating the electricity distribution network in greater Wellington. Direct peer operating under the same NZ EDB regulatory framework (Commerce Commission / Electricity Authority) with capex-driven asset growth.
• Orion Group: Electricity distribution and generation infrastructure company serving Canterbury and the wider South Island. Comparable EDB and embedded generator model with regulated network revenue.
• Unison Networks: NZ electricity lines business serving Hawke's Bay, Rotorua, Taupo and Taumarunui. Direct peer in regulated NZ distribution and increasingly embedded generation investment.
• Counties Energy: Consumer-trust-owned electricity distribution company serving South Auckland - extremely comparable ownership/governance structure to Top Energy. Direct peer operating under the same EDB regime.
• Horizon Energy Distribution: NZ electricity lines and distribution group operating in the Bay of Plenty region. Direct EDB peer with similar regional scale and operating model.
• Eastland Network / Eastland Generation: Community-owned NZ lines and generation group serving the East Cape / Gisborne region. Closely comparable to Top Energy as a small regional multi-utility combining EDB and embedded generation assets under community ownership.

Broad incumbents

• Mercury NZ: NZ-listed integrated generator-retailer with significant geothermal generation (similar technology to Ngāwhā). Comparable as a NZ renewable-generation peer but operates upstream of Top Energy's distribution function rather than competing directly.
