For site hosts
Get paid for power you’re not using.
Many plants, warehouses and campuses were wired for loads they no longer run. That capacity is already built and paid for. We connect it to companies that need it.
Why host
New revenue. Nothing to build.
Monthly hosting fee
Paid per kW of node capacity, for as long as you want to host. No capital from you.
Your load comes first
The node reads your meter and ramps down before your facility gets near its contract demand.
No install costs
Our compute partners pay for the pad, tie-in, cooling, fiber and permits.
Optional battery
Add storage to shave your demand charges and back up the node.
How it works
From utility bill to new revenue.
Find the headroom
Share 12 months of bills or interval data. We find your real peak and what the service can safely carry.
About 1 weekSurvey the site
We walk the switchgear, transformer, pad space and fiber route, and check with your utility.
2–4 weeksMatch and move in
A vetted compute partner funds, permits and sets the node. Your operations keep running.
Months, site-dependentGet paid
You earn a monthly fee. The partner runs the node. We stay your point of contact.

Headroom check
What could your site earn?
Two numbers from your utility bill give a first estimate of your hosting revenue.
Your site
Don’t know these numbers? Send us a bill and we’ll find them for you.
Estimated node size
Method: usable capacity = service × 0.9 power factor. We keep 20% as reserve, subtract your peak, and round down to 250 kW. Sites run 1 to 20 MW. Fees assume $8–$15 per kW-month; real terms depend on the site, tariff and contract. A survey replaces all of this with real numbers.

Host FAQ
What does Annex Power cost me?
Nothing. Our fees come from the compute side, not from you. You earn a monthly hosting fee and pay nothing to get started.
How much could I earn?
Fees are paid monthly per kW of capacity the node uses. The headroom check gives a first range; a site review turns that into a real number based on your service, utility tariff and contract length.
Will this raise my demand charges?
The node is metered separately inside your service and ramps down as your facility’s own load climbs, so your billed peak stays where it was. If a battery is added, it can lower your demand charges.
Who pays for equipment and upgrades?
Not you. The compute partner funds and owns the node, pad, conduit, switchgear tie-in, cooling, fiber and permits, and handles maintenance.
Will it affect my operations or power quality?
The node sits on its own protection and metering, reads your load in real time, and ramps down before your facility needs the capacity. Your equipment always comes first.
How long are the agreements?
As long as you want. Compute equipment typically has a 2–5 year life, so each node is refreshed on that cycle, but the agreement can keep running for as many years as it works for you.
What if I need my capacity back?
Agreements include a recall clause with notice. The node is containerized so it can be moved to another site.
How loud is it?
Dry coolers make fan noise similar to rooftop HVAC. Nodes are placed and screened to meet your local ordinance at the property line.
Does my utility need to be involved?
Sometimes. If the node stays inside your existing service, it is usually a notification or a load letter. If a service upgrade makes sense, we coordinate it with you and the utility.
