Energy, transmission and distribution, taxes and levies, operations and margin, plus indexation, so you can compare offers that use the same words.
"All in", followed by a single number per kilowatt hour, describes what the invoice will look like, not what it contains. Two operators can build the identical headline figure out of very different pieces, and if you have not asked what is bundled into that number, you have a price you cannot compare to anything.
We have written separately about what makes up the underlying power price: the energy component itself, transmission and distribution charges, and the taxes and levies layered on by the jurisdiction. That piece is about the electricity. This one is about what the host does to that electricity before it reaches your invoice, because a hosting rate is the power price plus a set of decisions the operator has made about bundling, margin and risk that a fleet owner rarely sees itemised.
What sits inside the base rate
A hosting rate is not simply the power price with a margin added. It is usually a bundle of several things priced together: the energy itself, the operator's margin, and some portion of the site's fixed costs, which can include facility operations, staffing, and the amortised cost of the electrical and cooling infrastructure your rack sits behind. How much of that fixed cost is folded into the per-kWh figure versus billed as a separate hosting or colocation fee varies between operators, as does the margin itself, and it is the main reason a lower headline rate does not always mean a lower total bill.
The way to get past this is to ask the operator to itemise, not to trust the bundling. A rate that separates energy cost, operator margin and facility fee lets you compare the energy component against the market price you already understand, and evaluate the margin and facility fee as their own line items rather than accepting them folded into one number that hides which part is negotiable.
What tends to sit outside it
Even a genuinely all-in quote usually has a list of things that are not in it. Common exclusions include remote hands beyond a defined baseline, network or bandwidth charges above a threshold, insurance, and any work related to hardware failures or replacements. Billing these separately is not unreasonable. The problem is when they are not disclosed until the first invoice that includes one.
Ask for the exclusion list in writing, not the inclusion list. An operator who can hand you a short, specific list of what is billed separately, with the basis for each charge, has already done this exercise for other clients. An operator who says "everything is included" without being able to name what could possibly be additional has probably not been asked the question before.
How indexation is worded
Most hosting rates are not fixed for the full term, and that is not inherently a problem: energy markets move, and a rate that never adjusts either overprices the risk into the initial number or transfers all of it to the operator, who will eventually need to pass it back one way or another. The part to scrutinise is the mechanism, not the fact that indexation exists.
Read for four things. First, which components move: does indexation apply only to the energy portion, or to the whole rate including the operator's margin, because those are very different exposures. Second, against what benchmark: a named, published index that you can check yourself is a different commitment than "market conditions," which is not a benchmark at all. Third, how often it resets, and whether the reset is automatic or requires the operator to give notice with a lead time you can plan around. Fourth, whether there is a cap or a collar, meaning a maximum movement per period, or whether the adjustment is unbounded. A rate with unbounded indexation on the full figure is not really a fixed offer with a variable feature. It is a variable offer with a fixed number attached to it for the first invoice.
Comparing two offers that use the same words differently
The reason two "all in" quotes can diverge is that operators are not lying when they use the phrase. They mean it is all in relative to whatever they have defined as the base scope, and that definition is exactly what differs. A rate with a wide base scope and no indexation on margin can end up cheaper over a real term than a lower headline number with a narrow scope and full indexation, even though the first quote looked more expensive on the day you read it.
The only reliable way to compare is to normalise both offers to the same structure before comparing the number: energy, transmission and distribution, taxes and levies, operations and margin (with any facility fee shown on its own), what is excluded, and the indexation terms on each piece. Put both offers into that same table and the headline figure often stops being the interesting number.
What to ask for before you sign
Request an itemised breakdown of the rate rather than the single figure, covering energy, transmission and distribution, taxes and levies, operations and margin, and any facility fee, stated as separate lines. Ask for the exclusion list in writing, with the basis for each item on it. Ask which components are subject to indexation, against which named benchmark, on what reset schedule, and whether there is a cap. And ask what the invoice looks like for a typical month, not the term sheet summary, since operational billing sometimes reveals structure that the sales document does not mention at all.
You do not need to become an energy trader for this. What it takes is treating "all in" as a phrase that needs a definition attached to it before you use it to compare two numbers. Our hosting rate page sets out the components of a rate per kilowatt hour and what sits inside our own base rate, so you can see the structure before you ask for a quote.
