Grid-Extension Avoidance
What does it cost to run poles and wires out to a remote site — and what capital would a site not spend if it did not have to?

Before redundancy. A real deployment would size for N+1 or better; this calculator flags that rather than assuming it.

Capital cost only — what is excluded
- This figure is capital cost only. It excludes ongoing network losses, line maintenance and vegetation management, and easement, land access and native title costs — each of which needs site-specific quotes and legal work.
- It excludes any cost on the microreactor side, and excludes the cost of the generation a network extension would have delivered.
- It does not account for a network business’s own connection policy, contribution arrangements, or whether an extension would be approved at all.
- The band is presented as a range because the underlying source is a range. No single point estimate is offered, and false precision is deliberately avoided.
- Nothing here implies a network extension is uneconomic or unavailable in general. Uranium endowment, AUKUS and manufacturing statistics are not evidence about network cost and are not used in this module.
Open data gap
The A$4.6–13.1M/km band is project-derived, sourced to an internal Deployable Energy cost report and used across the project’s addressable-market work. It has not been reconciled against a public per-kilometre benchmark.
The independent cross-check is the AEMO Transmission Cost Database, which publishes cost benchmarking by line type and voltage class. Pulling AEMO line-item figures and reconciling them with this band is a launch gate for this module. Until that is done, treat the output as an order-of-magnitude illustration.
Method
The formulas, in full
The unit-cost window is taken from the single published band of A$4.6–13.1M/km. The voltage-class control positions the window in the lower or upper half of that band, and the low/mid/high control narrows it. Both controls are presentation devices for navigating one range. Neither introduces a new sourced number, and the widest possible output remains bounded by the published band.
Distance is a straight-line input. Real route length exceeds straight-line distance, often substantially, so a real project’s route kilometres should be entered rather than map distance.

General information only
This calculator provides general, illustrative information only about hypothetical energy-generation scenarios. It does not take into account your personal circumstances, objectives or financial situation, and does not constitute financial product advice, an offer of securities, or a recommendation to invest in Deployable Energy Fund Limited, Deployable Energy Limited, or any other entity. Figures are drawn from third-party Australian government, regulator and industry sources (cited on this page) and, where expressly badged, from Deployable Energy’s own unverified planning assumptions. They are provided for general educational and illustrative purposes only. The Unity Battery microreactor has not yet been deployed commercially, and civilian nuclear power generation is not currently permitted in Australia under the EPBC Act and the ARPANS Act (and, in several states, additional state legislation). Nothing on this page should be relied upon as a representation that deployment in Australia is imminent or currently lawful.
