Google on Wednesday unveiled plans to put in its first backup battery at a knowledge middle, with ambitions to make use of the undertaking as a check case for grid service purposes.

The three-megawatt, 2-hour length battery can be put in at a Google knowledge middle in Belgium, a location chosen as a result of the market has insurance policies that permit batteries to supply frequency regulation to the grid. Google is already experimenting with load shifting on a pilot scale.

Google has matched its general electrical energy consumption with 100 p.c renewable vitality purchases since 2017. The battery set up is designed to assist Google on its quest to satisfy around the clock electrical energy demand with carbon-free sources by 2030. Along with offering clear backup, batteries even have the potential to carry again worth, stated Maud Texier, Google’s carbon free vitality lead.

“That is actually not a know-how pilot, that is actually extra of an operational pilot,” stated Texier. “We wish to show that there’s a enterprise case. Batteries are value aggressive right this moment … [And] there may be an financial incentive for purchasers akin to us… to change into lively individuals within the grid.”

Mills sit beside knowledge facilities the world over, prepared to maintain them working in case of electrical energy outages. Presently, knowledge facilities account for about 20 gigawatts of diesel turbines across the globe, Google estimates (the tech firm declined to quantify its share of that whole).

If these customers swap knowledge middle backup to batteries, it might drive some storage demand. However this announcement is extra about potential worth creation than upside for the battery market, stated Dan Finn-Foley, head of vitality storage at consultancy Wooden Mackenzie.  

“If the Googles, Microsofts and Amazons of the world are keen to pay a premium [for] cleaner backup era then it could nicely speed up the uptake of storage by offering yet another layer to drive economics into the black,” stated Dan Finn-Foley.

Information middle backup energy for grid companies: an extended highway to realization

The push to make the most of knowledge middle backup energy methods as vessels for grid companies contracts has been round for no less than a decade. In 2011, Greentech Media reported on a partnership between utility Dominion and Energy Guarantee, an vitality administration software program startup that deliberate to make use of knowledge facilities as grid property to bolster effectivity. The corporate dissolved in 2014.

Bloom Vitality gasoline cells have provided prospects akin to Apple. Microsoft has dabbled in batteries, and extra not too long ago, inexperienced hydrogen to supply backup at its knowledge facilities. None of those purposes has change into widespread.

All of the whereas, massive tech corporations have change into among the greatest patrons of unpolluted vitality on this planet. Fashions recommend knowledge facilities account for about 1 p.c of world electrical energy use, and extra corporations are working to energy them with renewables. That demand has allowed corporations like Google to form markets; the tech large has already joined the Midcontinent Impartial System Operator and the Southwest Energy Pool. The corporate’s newest transfer into grid companies might wield comparable affect, if it grows past the pilot.

“One of many cooler parts of that is the whole reversal in enterprise fashions. Information corporations are large customers of electrical energy. A motion in direction of renewables-plus-storage as backup might flip it so they’re among the largest turbines and repair suppliers on the grid,” stated Finn-Foley. “In case your job is to promote electrical energy it have to be unnerving to observe one in every of your greatest prospects changing into a competitor as an alternative.”

The undertaking, because it stands, is on a small scale; Google nonetheless plans to make use of diesel turbines in tandem with the battery. But when it turns into a repeatable and widespread mannequin, the corporate’s rising affect within the vitality business might assist spur “a brand new paradigm — the place storage on the grid permits extra renewables, slightly than a build-out of renewables encouraging extra storage,” stated Finn-Foley.

In reporting on its environmental targets, Google doesn’t get away emissions from turbines, which run sometimes, Texier stated. And the corporate’s whole scope 1 emissions, people who embody direct emissions together with onsite diesel turbines, account for a fraction of Google’s general emissions.

Changing these turbines with clear vitality applied sciences is not going to considerably lower the corporate’s emissions, stated Texier. However Google is hoping to make use of the shift to show a change in how backup methods will be designed.

“We’re actually attempting to have a look at these backup methods as extra like a possibility,” stated Texier. “We’d like backup capability onsite. How can we benefit from them, when they’re sitting idle more often than not, for carbon free vitality and different sustainability efforts that additionally help operations down the road?”
