Transform your existing roof infrastructure into renewable energy assets that generate extensive financial savings, energy security and resilience.
The opportunity
Kallan Energy demonstrates the savings potential over the full 25-year asset life (including battery replacement at Year 10), modelled against your actual capex expenditure. We streamline the process by working directly with New Zealand’s top commercial installation partners — delivering an additional ~10–12% in annual savings above what standard installers achieve by leaving systems on factory default settings. Kallan also shines a light on possible avenues to explore in minimising capital expenditure — such as green loans and NZ’s Investment Boost.

Gain clarity on which energy system is best suited to your energy profile.
Energy Systems — Solar only or the trio (Solar + Battery + AI)
All business energy cycles and demands are unique. Some operate during sunshine hours and don’t require battery storage; others with 24/7 operations, intensive machinery or cooling equipment require battery — and all battery cycles can be optimised greatly with AI. Some energy bills are oriented towards Time of Use charges, others are more capacity and demand weighted. Kallan Energy identifies which system you need based on your business type, and models the approximate savings from your existing energy data — before you make any decision to proceed with a full feasibility engagement.
Profile A · Solar-aligned
Daytime production, load aligned to the solar window.
E.g. commercial kitchens, daytime workshops. Major equipment runs during production hours; overnight base load is modest (refrigeration only). Demand/capacity charges are not a material share of the bill.
Typical bill reduction
14–32%
Trio would be over-spec — we walk away from the battery. The measurable ~10–12% Advantage (smart control configuration + AI adaptive optimisation + PF correction) doesn't apply to solar-only, but the structural Kallan Energy Advantage still does: loan-ready documentation, quarterly Performance Assurance. Detail below.
Profile B · TOU-weighted trio
Evening, overnight or 24/7 operation on a time-of-use tariff.
E.g. hospitality, supermarkets without major demand charges, evening-trade retail. Load extends well past the solar window; battery is what reaches it. Capacity charges are present but modest (<15% of bill).
Typical bill reduction
20–35%
Solar fraction is lower than Profile A (load extends past sunset), but battery time-shifts surplus into peak-priced hours. The full Kallan Energy Advantage applies here: measurable ~10–12% (advanced smart control configuration, AI adaptive optimisation, and PF correction) plus the structural stack — loan-ready documentation, quarterly PA.
Profile C · Demand-weighted trio
Evening or 24/7 operation with material Vector capacity charges.
E.g. cold storage, food processing, commercial laundries, supermarkets with peak refrigeration banks. Capacity charges run 15–30%+ of the bill. Peak-shave is the largest single saving stream; the asset case is usually the strongest of the three.
Typical bill reduction
30–43%
Peak-shave $ value is computed from your Vector capacity-band rate card — defensible and independently auditable, not an installer estimate. Full Kallan Energy Advantage applies: measurable ~10–12% (smart control configuration + AI adaptive optimisation + PF correction) plus the structural stack (loan-ready documentation, quarterly PA).
Ranges are indicative for typical Auckland mid-commercial sites at current pricing (May 2026). Actual bill reduction varies with consumption volume, load profile, tariff structure, available roof space, network connection constraints, and system design — and can differ materially from these benchmarks. Your approximate savings are modelled at Stage 1 from your EIEP3 data; your design-based projection is produced at Stage 2, once site assessment and system design are complete. The savings stack below shows how the streams combine on a representative trio site.
Business archetypes spanning solar-only and AI + battery + solar trio systems.
Business archetypes illustrating potential savings
Not every site needs the full trio (AI + battery + solar). These nine illustrative examples span solar-only and the full trio, across different load profiles. Payback figures shown are simple payback on installed cost (system cost divided by first-year savings). Solar panels carry a 25-year performance warranty, so the asset generates returns well beyond any payback shown here. Trio figures include two batteries in the capex assumption (battery warranted life: 10 years; one replacement at Year 10).

Early-morning oven and proofing load peaks before sunrise — solar can’t capture that pre-dawn peak, but battery dispatch can. The full trio stack is warranted here. Demand-charge exemption excluded.
Indicative figures based on modelled archetypes. Actual savings depend on your roof area, load profile and energy data — that’s what a site-specific model confirms. Commercial Kitchen figures are from a real verified installation. At Stage 1 we model your approximate savings using your own EIEP3 consumption data. Your investment projection is produced at Stage 2, after site assessment and system design.
Five savings streams, stacked into one asset.
The savings stack
Every recommendation is built from a five-component savings stack — each stream modelled separately, attributed to a specific hardware or control behaviour, and verified against your actual Vector tariff. The numbers below are illustrative for a representative 50 kW solar / 50 kWh battery trio on a $100,000/yr commercial energy bill. We model yours specifically at Stage 1.
Illustrative for a 50 kW solar / 50 kWh battery trio on a $100,000/yr commercial bill, modelled at Auckland Vector ALVT TOU tariffs (May 2026). Streams 02, 03 and 04 are the measurable Kallan Energy Advantage — ~10–12% of total bill. Smart control configuration (~6%), AI adaptive optimisation (~2–4%) and power-factor correction (~2%) are delivered by Kallan Energy specifying the system and our installation partner commissioning it to that specification. Most installers skip that step. The structural Kallan Energy Advantage (procurement, loan-ready documentation, PA) sits alongside and is detailed below. Your numbers are modelled site-specifically at Stage 1 from EIEP3 data and your actual Vector tariff.
Kallan Energy enables 10–12% more savings than the average installer.
The Kallan Energy Advantage
Kallan Energy enables greater savings, a streamlined process, and the highest performing energy assets.
★ Measurable — ~10–12% of total bill
Advanced smart controls and PF correction are capable in every trio system. Most installers never configure them to the site.
Most NZ commercial solar quotes are written to close, not to optimise. The trio system ships with rule-based factory defaults — smart control and PF correction capabilities are built in, but only perform to their potential when manually configured to each site’s specific load profile and tariff schedule. Most installers don’t do that work. The hardware is capable; the commissioning is not.
Kallan Energy writes the smart-control and PF-correction specification before procurement. Our installer partner then manually configures the system to your site’s specific energy load — not left on factory defaults. Once correctly configured, the AI continuously monitors load patterns, weather forecasts, and grid conditions, dynamically adapting dispatch within that framework — that adaptive layer is the additional ~2–4%. The ~2% PF correction follows the same logic: built into the hardware, dormant until manually activated and tuned. That’s the ~10–12%.
- Advanced smart control configuration
- ~6% × $100K = $6,000/yr
- AI adaptive optimisation
- ~2–4% × $100K = $2,000–$4,000/yr
- Power-factor correction
- ~2% × $100K = $2,000/yr
Applies to trio architectures only (Profiles B and C above). Verified quarterly post-commissioning via cloud telemetry in the Performance Assurance report. Smart control configuration (~6%) and PF correction (~2%) require site-specific manual commissioning to activate — the counterfactual is factory default settings, which is standard practice across the NZ market.
Structural
Five decisions made in your favour — before the install starts.
This part of the Kallan Energy Advantage doesn't appear as a number on the energy bill. It operates further up the decision chain — in how the system is sized, who quotes for it, how it's financed, how performance is verified, and how the risk profile of the investment is reduced.
- 01 Curated installation oversightKallan Energy specifies the system to a performance benchmark, then oversees the installation against that specification with a trusted, hand-selected installation partner. No over-spec, no hidden variance.
- 02 Loan-ready asset documentationA structured data pack — capex schedule, savings projection, asset classification — built to what a bank generally requires to assess a commercial green-loan application. We don't broker, refer, or earn commission from any lender; you approach your own bank directly, with the paperwork already done. Indicative rates currently sit around 4% (a rounded, conservative working figure, not a quote from any specific bank), and LVR is generally available subject to your bank's assessment of your revenue and credit profile.
- 03 Quarterly Performance AssuranceCloud telemetry verifies realised vs modelled performance every quarter. Variance is attributed to one of three buckets — warranty, baseline drift, tariff change — so accountability is clear.
- 04 Tariff- and load-aware modellingEIEP3 half-hourly + your actual Vector tariff (ALVT TOU vs ALVTD DER, capacity bands, the lot). Generic ROI calculators over- or under-state by 20%+. Our number is real.
Applies regardless of architecture — solar-only candidates (Profile A) get the same structural Kallan Energy Advantage as trio clients. It's about the decision process, not the hardware.
High-performing energy assets that enhance your bottom line and contribute to a renewable energy future.
Why the asset case works
When sized correctly for your load profile and dispatched intelligently, a behind-the-meter energy system becomes a piece of cash-flowing infrastructure that sits on your balance sheet and pays you back — every month, for 25 years. Under green loan financing, the monthly energy savings service the loan — the asset effectively funds its own acquisition. Once the loan clears, those savings become direct bottom-line contribution for the remainder of the asset life. Solar panels typically last 25 years; one battery replacement at Year 10 is modelled as a known cost.
Cash-flowing infrastructure
Energy savings flow to the bottom line as avoided cost. Unlike a marketing spend or a CSR donation, every dollar saved on power compounds into business profit, year after year — for the 25-year asset life.
Tax-advantaged at install
For a profitable taxpaying business, the NZ Investment Boost (20% accelerated deduction) plus standard depreciation may reduce the year-one cash impact materially. Kallan Energy flags Investment Boost eligibility in your data pack — your accountant confirms applicability and quantifies the tax outcome.
Green loan eligible
NZ commercial green-loan facilities, generally available subject to your bank's assessment of revenue and credit profile (rates currently around 4%), treat these systems as eligible capital assets. Clients can deploy minimal own-cash and have the bill reduction service the loan during its term — turning what looks like capex into a self-funding operating decision.
How payback on cash deployed varies by financing structure.
How capex is recovered
The financing structure you use is the single biggest variable in how quickly you recover what you put in. Represented below are illustrative scenarios for a representative commercial trio site.
Where a business qualifies for full green loan financing, cash deployed is the Kallan advisory fee only — the fastest possible payback on cash you personally put in.
At 10% deposit plus the Kallan advisory fee, Year-1 bill reduction typically recovers your cash deployed inside twelve months.
Where 50% equity is required by your lender, payback extends to three to four years — still well inside the 25-year asset life.
Full system cost deployed from operating cashflow. Equivalent to payback on total system cost — the financing-neutral baseline.
A seven-phase engagement, from energy assessment to performance-assured asset.
The process
Stage 1 (Feasibility & Specification) delivers the Indicative System Economics Model and architecture recommendation. Stage 2 (Procurement & Delivery) only begins once you elect to proceed, and ends with a 12-month Performance Assurance window on the commissioned asset.
Energy Assessment
Twelve months of EIEP3 half-hourly consumption data analysed. Tariff structure reviewed. Load profile classified as Profile A, B, or C. Initial site visit.
System Options Assessment
We model trio vs solar-only against your load profile and energy bill — sizing, savings, and payback compared. A recommendation, not a design.
Energy Asset Feasibility
Capex envelope, savings projections, payback analysis, and sensitivity table — modelled from your actual load data and Vector tariff. Illustrative financing assumptions are included to show how payback on cash deployed shifts under different equity positions (indicative only — financial advice is your accountant's and bank's lane, not ours). CFO/accountant data pack delivered alongside: operational facts only, for your own adviser to build the after-tax and financing case.
Energy Asset Design & Performance Requirements
We define the performance requirements that govern the energy asset design: output targets, smart-control behaviour, and commissioning parameters. The installation partner designs and builds to this brief.
Installation Partner Engagement
Your performance brief goes to our hand-selected installation partner. They do the technical design, build, and commissioning — and hold the workmanship, system and performance warranty.
Final Energy Asset Package
Feasibility model updated with the installer's actual pricing. Board/lender summary produced. Installer contract reviewed for specification alignment. Final Asset Package delivered; installer contract executed.
Performance Assurance Window
