New Biogas Plant is Apple's New Development and Not A New Data Centre Says Wired News

Apparently construction seen starting at Apple's Maiden data center. hs been causing industry rumors Apple was seen to be building something new at its Maiden, North Carolina, data center, but the uber-secretive company wouldn’t say what it was. So, the Wired Blog took to the skies to find out.


(Work which has now started is not visible on this older video, nevertheless you can get a feel for the scale of the development from the video. above. This is truly great publicity for Anaerobic Digestion, and biogas production from it.)

Overhead photos shown on their website, taken last month show Apple’s $1 billion data center and two adjacent areas where Apple has started new construction. In the IT industry rumors were flying aound which suggested that Apple was building a second data center beside the first, but judging from their photos and from county building permits Wired says it is most likely that this is not the case. In fact, in all likelihood, the two construction areas will house the new-age biogas fuel cell plant and the massive solar array Apple will use to help power the original facility.

The Maiden data center is home to Apple’s iCloud service, a way for consumers and businesses to store files, photos, and other data on the web and use it across a wide array of devices. The data facility itself cost $500 million, but Apple has pledged to spend $1 billion on the site over the next decade. Opened for business around the beginning of the year, the Maiden center is just one of the many custom-designed data centers the giants of the web are building to supply their ever-growing array of web services. Google has built several of its own dedicated data centers across the world, and the likes of Microsoft, Facebook, and Yahoo aren’t far behind.

The iCloud has been growing like gangbusters since it was introduced last fall, and when Apple pulled a few construction permits early last month, that prompted speculation that the company may be doubling down and building a second data center on the site. But clearly, that’s not the case — though Apple is starting to build a new data center on the other side of the country, right next door to Facebook’s massive facility in Prineville, Oregon.

To power its data center, Apple is building both a biogas fuel cell plant and a solar array.

Apple’s North Carolina permits describe a 21,030-square-foot building. That’s bigger than your typical Apple Store, but not nearly big enough for the sort of data center Apple would build. The company’s existing Maiden facility is 500,000 square feet.

More likely, the new building will house the 24-200 kilowatt fuel cell systems that could be partially operational as soon as June. This plant is noteworthy, as it will be one of the largest such plants in the U.S. and it’s the biggest such project built by a data-center operator.

But judging from our photos, even when the biogas plant goes live, Apple will still have room to squeeze a second massive data center into the spot — should the need arise. Maiden Town Planner Todd Herms told us where the solar array was being installed, but he didn’t know if the new building next to the data center was the biogas plant or not.

A second, somewhat sobering observation is that Apple had to mow down an awful lot of trees in order to build its environmentally friendly 100-acre solar array, right across the street from its data center. You can see the before and after photos here:

Before construction, there were 100 green acres on the other side of Maiden's Startown Road.

Now it's been razed, to make way for Apple's solar array !

Apple solar array effort has already come under fire from a data center guru James Hamilton at rival Amazon, who said last month that it just may not make sense to use so much land for a solar array that may end up generating a fairly small fraction of the data center’s power. Apple bills its solar farm as a 20-megawatt array, but that represents the solar farm’s peak capacity on a sunny day. In reality, it will probably produce less power than the 4.8-megawatt biogas facility, according to Gary Cook, an IT analyst at Greenpeace.

Those that know the Anaerobic Digestion process will not be surprised by he cirticism being made here of the capability of the solar array, compared with the AD Plant, and it is good to see the comparison of AD/ biogas production to produce power capacity overall being recognised. It could also have been added that the biogas plant will be able to meet demand for power when it is really needed, that being at night when it is really cold, as well as in the daytime.
