FCC Requires Backup Power For 210K Cell Towers 248

Posted by kdawson from the generating-controversy dept.
1sockchuck alerts us to an article in Data Center Knowledge that explores ramifications from the FCC's decision a couple of months back to require backup power for cell sites and other parts of the telecom infrastructure. The new rule was prompted by wireless outages during Hurricane Katrina. There are more than 210,000 cell towers in the US, as well as 20,000 telecom central offices that will also need generators or batteries. Municipalities are bracing for disputes as carriers try to add generators or batteries to cell sites on rooftops or water towers. The rules will further boost demand in the market for generators, where there are already lengthy delivery backlogs for some models.

      Cellphones weren't considered vital infrastructure before. And even now it is hard to argue that they can be since you can't always guarantee a usable signal in all locations (which makes it less useful to emergency responders) and since cellphone networks can easily be overwhelmed in emergencies where everybody gets on the phone at once, like during the 9/11 attacks.

      At the same time, when cellphones are usable, they can be very helpful. If many of the cell towers didn't fail during Katrina, it would have been much easier to help many of the victims and coordinate the rescue in a more efficient manner.

            The only problem with diesel is that it goes bad after a while. We provide emergency power with three V12 diesel engines (providing roughly 300 kW at full capacity), but only keep about four days worth of diesel in the tank so we don't have to replace as much when it degrades. We do have special agreements with the gas companies, being a vital infrastructure site, though.

        Not quite as silly as you might think. In rural locations, it is quite possible that the power failure is very local (eg a possum climbed up the pole the night before and cooked a fuse (and itself)), and the power company won't know about it unless you tell them. Phoning up a neighbor is a reasonable thing to do in that case.

        This used to happen all the time at my mums place. The outage would affect her and the weekend house across the road (who would most likely be away). The neighbor up the hill would be a good indicator to it being a possum induced fuse failure or something more widespread.

        Ditto for a failure in your fusebox. If everyone else has power and you don't, there isn't much use calling the power company... I know most people reading this would have a tripped breaker fixed in a few seconds, but maybe your grandmother wouldn't know how to, and in fact she might still have fuse wire instead of a resettable breaker.

        Even for the mail server case, a user in a remote branch who hasn't received any email all morning would probably ask if the server was down before bothering you with their specific issue. Of course a good helpdesk would put up a recorded message in that case eg 'We are currently experiencing problems with our email server, we expect the problem to be fixed in xxx minutes'.

      Not so. That all depends on where the damage is. If it's at, or fairly near the tower, quite possibly. If the power's out because a power line was dropped by the temblor, there's a good chance that the cell tower and any generator are just fine. I remember after the Northridge Quake there were major power outages, but the equipment worked just fine as soon as the power was back. As far as floods go, there's no reason not to install them in waterproof rooms to make sure they're OK even if that room's under water.

          Simply a matter of proper design so that they're far enough apart that the intake isn't sucking in the exhaust. Of course, there's always the possibility that the flood water will be deep enough to submerge them, but as long as they're above the surface the generators could keep working. (Yes, refueling them might also be a problem. Nothing's perfect.)

    • Presumably the tower would be located on high land or on top of buildings, putting it and the generators at lower risk of rising floodwaters. And during earthquakes, large amounts of buildings don't usually collapse. A few older buildings and structures collapse and large numbers of buildings receive light to moderate damage. Power failures are caused mostly by ruptured transmission lines, not by knocking out the actual power source.

    Maybe self powering solar paneled towers might be better. You'd be helping the environment as well as providing backup. And the height of these towers are perfect for a wind turbine + battery installation as well.
    Even if it's not perfectly reliable, such a tower could be connected to the grid, and in the event of emergency, it'll be at the very least, intermittent,which is enough for some traffic to flow out for a very long time. With a battery/generator, you'd only have power, while reliable, for a limited amount of time.

      To provide solar power to a cell site would require several hundred square feet of space to mount the panels. Sizing a solar power system for infrastructure requires planning for when the amount of sun is at the minimum (approx 2 hours during wintertime at northern latitudes). A aolar system must put a full charge on the battery system to account for charging losses, battery inefficiency, and the continual demand of the load. To match up to a solar power system you need a very significant battery string (when I do system calculations I assume that the system can go for three days without sun). Mounting a wind turbine on a cell tower is problematic too. An antenna structure has a loading (ANSI 222 (f or g)) that has to account for ice, maximum wind and the surface area of the tower, feedline, antennas, etc... A wind turbine adds ALOT of loading to a structure. I suspect that 90% of the cell towers out there right now could not pass the structural analysis under ANSI.

      Don't laugh. I've worked for a rural telco, and when the power went out, we had enough batteries to run for a bunch of hours (8+) at our remotes. So we had some time before we had to go and put the generators on (they where not automatic, unlike the CO). We had a couple of cases where someone would actually steal the gen off the side of the remote. It had happened enough time, that as part of our y2k plan, we actually had armed members of the line crew set to stand guard at some of the more remote, remot

    They should require some kind of ambient power generation also to be included. Solar cells are well understood perhaps but IIRC they do not have long lifetimes. So either some special long-lifetime solar cell, or something that uses environmental (humidity, electrostatic charge, temperature, gas, wind, etc.) gradients. It only has to be able to provide a very short window of time, perhaps only 30 min. per day, in which it can operate without any input from the power grid. If such a thing exists/can be devel

      So you're saying for a worst case situation, where the batteries die, the generators are out of fuel, everything is down--and this solar panel or whatever sits there all day gathering sun and then at a predetermined time it runs the tower for 30 minutes so people can text their parents or whatever. Not bad idea, it would be extremely cheap to implement, and in the worst case scenario, it would continue to allow some communications. Coupled with fuel cell or hand-crank power for the cell phones themselves

    • If gensets are installed at remote cellular sites, the testing can all be done remotely (genset startup, short runtime for monitoring, and then shutdown). Fuel level can also be monitored remotely (via TCP/IP even if you want, with a slim web server). Plenty of unmanned data centers do this sort of remote monitoring/testing already.

    Regarding hurricane Katrina:

    I work for a large cell carrier. We had backup power to every single cell in the area. In fact, after the hurricane we were doing pretty well, though some of the towers were taken out by debris. Only a couple were actually submerged. We lost a few trunk lines, but for the most part the system was working.

    The problem was we didn't have any way to get gas to the generators. The roads were impassible, and based on news reports we were reluctant to send crews in to the sites we could reach for security reasons. So after a couple days the cell sites started going offline one at a time as the generators ran out of power.

    As far as I know every one of our sites, in the entire country, already has a couple days worth of backup power.

    Electromechanical Batteries or EMB or Flywheel Batteries by their old name. These have the highest power density of any energy storage system. They are so reliable they can be buried or sent into space. They can hole huge amounts of power. They can be recharged very quickly. They do not burst into fire. They are not hazardous.

    Specific Power EMB (5-10 kW/kg) Lead Acid (0.1-0.5 kW/kg)
    Energy Recovery EMB (90%-95%) Lead Acid (60%-70%)
    Specific Energy EMB (100 Wh/kg) Lead Acid (30-35 Wh/kg)
    Service Lifetime EMB (>10 years) Lead Acid (3-5 years)
    Self Discharge Time EMB (Weeks to months) Lead Acid (variable)
    Hazardous Chemicals EMB (none) Lead Acid (Lead, Sulfur, & Acid)
    "A new look at an Old Idea the Electromechanical Battery" Science and Technology Review April 1996 by
    Dangerous EMB (possibly in massive physical impact) Lead Acid (High fire danger)

    Caterpillar and Beacon power already sell off the shelf UPS based on EMB for anything up to a whole grid substation. These are the answer to balancing the output of solar and wind power as well, far better than ice batteries or lead acid. These are the answer to solving our reliability problems with the national power grid (if each substation could self power for even a few 1/10s of a second you can reroute the grid. In fact these are even a possible answer to batteries for cars thanks to new fiber based flywheels instead of steel. There is literally no sound reason to use Lead acid to backup a data center, a telephone switch, or a cell tower anymore.

    The FCC should demand that the power backup meets a certain level of reliability and power density within a top percentile of the most cost effective solution so that people don't use old outdated technology just because it is a system that they are accustomed to.
