Next, we have our Article 706. Now, as the Internet has grown in size, so too has the need for things like data centers and the ability to store the energy adequately. And that's our technology has evolved with batteries itself. That's one of the primary reasons why we don't use the Brit from the 1980s and now we have our smartphones. And that's mainly because of battery technology. And this too has applied to the industry. And, as a result, the National Electric Code also corresponding with other NFPA series, I think it's in a NFPA 75 and 76, those refer to like data centers, for example, may have a lot of backup batteries, but this is to help dovetail the safety associated with such applications. As you can see here, even this specific part implies the various different ways that they're talking about energy storage systems. And it's not just referred to batteries, but as you could see, capacitor banks, kinetic energy devices like flywheels or compressed air because many of these backup power systems now are becoming more and more advanced and have become more energetic regarding or basically calling for a look by the National Electrical Code.
This is a typical energy storage system, much was that what I was referring to earlier. In many cases, like I said, will be part of the UPS system or code generation. And a lot of times, keep in mind, for those you guys who aren't familiar with, a lot of times, the purpose of these large battery banks is to supply basic battery DC power for only a couple of minutes just for you to affect the massive switch over your switch gears and switchboards to then, of course, call on a generator. And the idea of course is to affect that transition as seamlessly as possible.
Then, of course, Article 710, standalone systems. Now, one of the things that's also involved is our electrical grid expands into more and more remote locations as we're getting to more industrialized areas where we're trying to put whether it be an oil someplace or an agricultural irrigation tap someplace. The code is now adopting. We have standalone system. Basically, you have a generator in the middle of a field someplace, in the middle of nowhere that provides power to a couple of pumps for irrigation, for example. This will be an area where this article would apply. It once again it goes into the area falls under the auspices of safety. For example, like anybody from Kansas knows that brush fires are quite common and the last thing you want to do is basically have an electrical issue that causes a massive brush fire. I think it was in 2013 where they had had a brush fire that started that destroyed hundreds of acres of land and basically, threatened population areas. That goes back to the purpose of the National Electrical Code.
So once again, on the cusp of changing technology. So, Brett current microgrids. This is referring to, like, if you have a standalone, like computers for example, many computers will operate on DC power. And as a result, because of now we're getting more and more higher power processing that is an example of when direct-current micro grids will be necessary. As a result, the code has developed a regulation for in order to make it appropriately safe. So an example here, and as you can see, this also dovetails with photovoltaic generation. This also dovetails with UPS power and any type of stored energy, batteries, capacitors, or flywheel-type stuff and that's to bring it all together because this is becoming more and more prominent as we become more and more...we as a public, become more and more thirsty for data via our smartphones and computer usage.
So many of the NFPA series in general are laid out very similarly, and they're done on this way on purpose so that way, you can refer to it with relative ease. Now, this also goes back, one of the things you must understand when taking National Electrical Code class is you must have a background knowledge of how electricity works, at least a little bit. Now, I recommend beyond the just electrical technicians or electrical engineers that anybody involved with safety, if you're involved with making decisions regarding construction or maintenance that this course is in your best interest to take. So, you have a better understanding of why the rules are what they are and exactly what those rules and how they pertain to you.
With that in mind, so one of the things we talked about is understanding the language and the layout of the National Electrical Code. You'll see things in the margins, for example, you have either are bold and italic N, that's an indication of brand new material. Other books will also leave a habit as what's highlighted in gray. That's awesome, in indication that there's been a move. And as you see, deletion. Now sometimes that doesn't always mean that it was completely removed. It can also mean that if you see a doctor, that means it was removed from that specific article because that wording or the idea behind that paragraph or whatever better fits in another article elsewhere. Sometimes, you'll have to pay attention to that as well for those of you who are familiar with previous versions of the National Electrical Code.
