Every project follows a structured pathway. This keeps risk low, ensures the system is right-sized for your site, and means pricing is confirmed before you commit to build.
It starts with your data, not our brochure. Tungsten models the value streams first, the business case follows the model, and the same engine then runs the asset it justified. Same code. Same people. Same accountability.
Twelve months of your interval data and your actual tariff go into Tungsten. The engine simulates the asset against your real year — every trading period — and quantifies each value stream separately, so you can see exactly where the return comes from.
The modelled value streams become a firm commercial proposal — system size, capital cost, projected savings, payback. Where EECA co-funding applies, we structure the application alongside your project. Pricing locked before build: the number in the proposal is the number the engine stands behind.
Cabinet count, electrical design, protection settings, and network approvals — including AS/NZS 4777.2:2020 connection with your EDB. Integration with existing solar, generation, and site systems engineered against real operating conditions, not theoretical models.
Supply, installation, and commissioning coordinated with your site operations. Civil works, switching, connection, and integration handled as one programme. We hand over to operations the moment the system is live.
Tungsten makes forty-eight decisions a day — each one logged, each one with a reason. Tariffs move, spot patterns shift, your load evolves; we re-tune dispatch strategy quarterly and report against the original business case. We don't leave.
In commercial BESS, the savings number in the proposal and the savings number on the monthly report often come from different tools — sometimes different companies. ASKA uses one engine for both. Ask us where any figure came from, and we can show you.
The numbers in your proposal and on your monthly report come from the same code. They don't drift.
Each decision the asset makes — charge, discharge, hold — is stamped with the time, the reason, the tariff band, and the price. Years of history accessible.
Every tariff in our model has the source reference and the effective date it was published. When a tariff changes, we know on which day.
Real meetings, not auto-emails. We sit down, re-tune dispatch strategy against the next quarter's conditions.
nz-tariff-2026-04-01f9e1a3dASKA brings together the technology, engineering, financing and delivery required to implement energy storage properly — all under one roof.
Hardware with a strong global operating history, factory-warranted and specified against the duty it will actually run — selected for the right job, not the only one we sell.
NZ site connections, network infrastructure, and integration. We know how the local market clears, half-hour by half-hour.
Engineering aligned with real operating conditions — not theoretical models. The number on the proposal is the number the engine delivers.
Support shaping the business case and financing structure. Where EECA co-funding applies, we structure the application alongside you.
One conversation. We model your load against your tariff and tell you honestly whether a battery pays back.
