Why have I heard of so many new DC projects all of a sudden? Seems like the DC projects in the Deep South waited around long enough for renewables proliferation. Seems like in 2H24 they just said “17 it” and started throwing new NG generators in the plans left and right. I’m sure it’s not as simple.
Are you familiar with Moore's Law? If not. it's not actually a law, per se, rather an observation of the advancement of information technology. It has been an incredibly accurate predictor of the exponentially increasing growth of IT and the need to address said growth.
Well, that's what it has become anyway. Technically it started in 1965 and referred to the predicted growth of the # of transistors we would find on microchips. It's morphed into a predictor of pretty much all information technology, and states we should expect a doubling every 2 years.
That has also meant a need for solutions to support that expected growth. It has proven reliable for decades and plays a big part in how companies react to that expected growth, both in the need for it to support their functions and for manufacturers, service providers, etc., to anticipate what the market is likely to need.
Well recently we blew right past this decades-long predictor. The exponential rate of acceleration is now dwarfing that previously held concept of a doubling every 2 years. With the advent of AI and the astonishing breakthrough Nvidia has made, that is now more like a doubling or more in a matter of months.
In order to support the current and expected future growth there is a need to increase our ability to handle that burst of technological advance, We need to provide the equipment and facilities to handle storage, processing, etc. Data Centers have become the most effective way to provide that, but as you can imagine, they require ungodly amounts of power/electricity.
And I'm not talking just about the power all that equipment requires, but the ability to keep them running cool enough to not fry. If you've ever been in one of the cages or blocks of cabinets stacked full of servers, with each server running multiple processors at extreme speeds you'd realize first, that the space farthest away can be rather chilly, but when you stand in the midst of those servers you can start sweating.
Consider your own laptop and the amount of heat it puts out. That is a teeny-tiny fraction of what you would get from one server in a cabinet. A typical cabinet holds 42 servers humming along. Each one of those servers can have 16 or more processors, so each cabinet likely has 672 or more processors in one single cabinet.
Modern hyperscale data centers can have thousands of cabinets. So, let's say we're looking at one that has 2,000 cabinets. That's 84,000 servers & approximately 1.3 million high-speed processors cranking away 24/7. It sounds like you're in the middle of a giant beehive!
So, back to your laptop and it's one processor that is most likely not nearly equal to just one of the processors in one server in one cabinet. Take the heat your laptop puts out, multiply that by 1.3 million (actually more because each server processor is subject to vastly more heat). You're probably getting a picture of how critical cooling is and how much power is required to power the cooling solutions alone!
So, you see the need for data centers. But now you can also imagine the burden placed upon any city's power grid. Many DC's have taken to building their own power plants, but those power plants have to generate power somehow and they need real estate to build such a plant, as well as to build and allow for rapid future growth of the DC itself (recall Moore's Law above).
Where are you gonna find lots of available real estate and where are you gonna find electricity rates lower?
