NANOG Community,
The NANOG 74 Agenda is published at http://www.cvent.com/d/qgqs03/16K
and available as an iCal Feed. The Program Committee has worked
closely with our speakers to develop a first-rate program and we
encourage all attendees to enjoy the whole conference. As we review

This isn't a data center specific answer but it may help explain upstream
cost drivers that may factor into rates seen. For commercial and industrial
customers, utilities will often measure and bill power demand in kW
separate from energy in kWh. Energy may only be $0.04/kWh but demand
charges can

We see lots of different approaches to this, depending on the datacenter
operator:
1. Customer pays for power overage at an agreed to rate that is usually the
same as their committed rate (but could be more). This could be based on a:
* Per KW consumed
* Per KWh consumed
If we saw a dc customer approaching their power limit we would typically
have a conversation or message them to make sure they were aware. If they
anticipated needing more sustained power we would update their agreement
accordingly. Sometimes it would be a one-time occurrence so we would
We would typically order a 20 or 30-amp 208v circuit per rack for a flat fee
then install a metered PDU to make sure we didn’t overload it. The flat fee
per-circuit seems pretty standard in the US. Using your own metered PDU would
help predict the usage if you’re being billed by kWH.

Telehouse London is 0.75 (GBP) per KWH of overage. Obviously it will depend on
datacentre/country. Telehouse increase this annually at 2% above inflation

The fuses might match what you ordered. If you go over you might lose power
due to a blown fuse.
When there is A and B power for redundancy, you need to make sure that one
side can take the whole load without blowing any fuses. Otherwise you have
no redundancy.
