Disaster relief · emergency response
After a major event, fuel decides how long equipment keeps working. Roads are closed, stations are down, and resupply is rationed. A machine that makes its own power joins no queue.
Pre-positioned in storage, stood up at a command post, staging ground or aid point. It keeps communications, coordination, monitoring and charging running while the grid is down.
Be clear about this
This does not restore power to homes, streets or neighbourhoods.
It is not a shelter power system either — heating, cooling, area lighting and dewatering are an order of magnitude beyond it. What it powers is the response itself: the radios, the link, the sensors, the charging. Saying precisely where that line falls is how the rest of these numbers stay worth something.
The constraint
Every option below works on day one. The question each response faces is what is still running on day five.
Tropical systems leave elevated wind behind them for days, and wildfire is driven by wind events. That is not true of every disaster — an earthquake carries no wind with it, and some sites will simply be calm. Where the resource is there, it is there at exactly the moment nothing else is.
Size a deployment point
Wind after an event is highly variable, so this does not assume a figure — you set it and the model answers. The loads that belong on a generator are listed too, and the tool will say so.

No single configuration covers this at 5.00 m/s. Raise the mast, add solar, or split these loads across two deployment points.
What does the response need to keep running?
One deployment point at a time. Each load shows its own draw, and the assembly above redraws as you pick.

Out of scope
Equipment draws are typical published figures for common response hardware, used here for sizing — not Coevo measurements. Generation is modelled from CFD report TR-26-0019 at the wind speed you set, which is the speed at the rotor rather than a regional average. Wind after an event is highly variable and Coevo publishes no deployment-site figure. No survival wind rating, deployment time or certification is claimed.
Why this, in an emergency
On an ordinary site most of these are conveniences. In a response they decide whether equipment is still running by the end of the week.
After a major event, fuel is the constraint that decides how long equipment keeps working. Roads are blocked, stations are down and resupply convoys are rationed. A machine that makes its own power does not join that queue.
A generator in a warehouse needs fuel rotation, stabiliser and exercise runs. A pre-positioned unit with a sealed bank and no fuel system waits in a container until the call comes.
Tropical systems leave elevated wind behind them for days, and wildfire is driven by wind. The conditions that caused the emergency are often the conditions this generates in.
The rotor turns inside its shroud. Deployment sites fill with responders, volunteers and the public, and an enclosed machine does not need an exclusion zone around it.
No engine noise over a command post, no carbon monoxide near a tent, a damaged building or an enclosed staging area.
Skid or trailer, no fuel aboard — which is what makes a unit straightforward to stage, ship and store in quantity.
Enclosure reduces direct contact with the rotor and removes on-site fuel and exhaust. It does not by itself establish compliance with any standard, and no survival wind rating has been published — structural limits in severe weather are not yet established.
How a fleet works
Agencies, utilities, campuses, hospitals and response organisations hold units the way they hold any other staged resource — except this one needs nothing while it waits.
01 · Pre-position
Agencies, utilities, campuses and response organisations hold units in stock. No fuel rotation, no exercise schedule — a charged bank and a sealed enclosure.
02 · Deploy
At the command post, the staging ground, the supply cache or the aid point. No grid, no generator, no fuel delivery in the plan.
03 · Sustain
Comms, coordination, monitoring and charging hold while wind and optional solar keep the bank up — through the nights, and through the days nobody can get fuel in.
04 · Recover
The unit returns to stock when the operation closes. It is an asset that waits, not a consumable.
Scope
Emergency buyers know exactly what a watt is, and people in a disaster deserve not to be told something that is not true. Both reasons point the same way.

Whether you are planning pre-positioned stock or sizing a single command post, the equipment list and the site decide the configuration. Send those and we will size it — or tell you plainly if wind is not the right answer where you are.
