Google 'excited' for potential of battery-based technologies at data centres


Carbon-free energy energy buy agreements (PPAs) signed by Google and a California group energy group may very well be a extensively replicable mannequin for different provide offers, Energy-Storage.information has heard.

California group selection aggregator (CCA) electrical energy provider Silicon Valley Clear Energy (SVCE) introduced final week that it has signed PPAs with the know-how large that matches Google’s native energy demand 24/7 with clear energy manufacturing.

Google is focusing on carbon emissions-free operating of its operations by 2030 and, like SCVE is headquartered in California, which has a state coverage purpose of 100% carbon-free electrical energy by 2045.  

SCVE in the meantime is a community-owned energy company which offers energy to members in six California jurisdictions. The ten-year deal will see SVCE serving the load of Google’s Mountain View and Sunnyvale workplaces to match demand with carbon-free energy for not less than 92% of hours a yr.

SCVE instructed Energy-Storage.information the settlement contains provide from a number of energy buy agreements (PPAs).  

Energy storage is an important element of the deal and the useful resource combine concerned, Don Bray, director of energy companies and group relations for SVCE, instructed Energy-Storage.information.

“Whereas SVCE and Google transition to a devoted set of sources, Google’s load shall be met with wind, solar-plus-storage, geothermal and different carbon-free sources,” Bray mentioned, with this evolving over time.

“In the end, Google’s load shall be met with 24×7 carbon-free sources comprised of wind, solar-plus-storage, geothermal and standalone storage sources.”

The workplace buildings have been designed with a excessive stage of electrification of their infrastructure in place already and Google itself has behind-the-meter {solar} and storage and different distributed energy sources (DERs), which may also be optimised to satisfy its carbon-free energy (CFE) wants, in response to Bray.

“[Energy] storage, each front-of-the-meter and behind-the-meter will play an instrumental function in assembly Google’s CFE targets,” Bray mentioned, including that SVCE and Google collectively “intend to deploy [renewables] paired and standalone storage of various discharge durations”.

SVCE believes it is a deal that may be replicated not solely throughout Google’s different amenities however may very well be utilized by the energy provider to create retail electrical energy choices of an identical nature for different industrial prospects.

It hinges on Google’s 24/7 CFE methodology, which the tech firm printed in February 2021, following the 2020 announcement of its carbon-free goal. Whereas the corporate already achieved internet zero carbon in 2007 and by 2017 had matched 100% of its consumption with renewable energy purchases, it now goals to function solely on CFE at its information centres and campuses all-year spherical.

“This settlement with SVCE permits us to each decarbonise our energy provide at Google, whereas additionally giving SVCE the chance to check revolutionary methods to decarbonise all their prospects,” Google head of energy and carbon Asim Tahir mentioned.

“The SVCE 24/7 carbon-free energy service with Google serves as a mannequin for a way massive industrial energy prospects and energy suppliers can work collectively to additional advance clear, carbon-free electrical energy on the grid, coupled with electrification efforts in the area people. Such a forward-thinking collaboration is an actual difference-maker in our full-scale transition from fossil fuels to scrub electrical energy,” SVCE’s CEO, Girish Balachandran mentioned.

Google’s curiosity in energy storage extends to long-duration

Associated developments for Google embrace a deal for round the clock clear energy to energy its information centre operations in Virginia from a US$600 million, 500MW portfolio of wind, {solar}, hydro and battery storage.

That deal, struck with energy and renewables firm AES Company would make its facilities in the southeastern US state run on carbon-free power 90% of the time, from a mixture of AES-owned and third-party belongings, AES mentioned on the time.

In September that yr, sister web site PV Tech reported that Google had signed a three-year, 140MW settlement with European utility firm Engie, for energy from a portfolio of storage-backed wind and solar in Germany, which likewise fell below the 24/7 CFE remit.

Additionally in Europe, energy storage system (ESS) supplier Fluence – which is part-owned by AES – equipped battery storage at a Google information centre in Belgium. The trial deployment, which permits the info centre to eradicate reliance on diesel backup turbines, could likewise be a model for replication elsewhere, according to Google.

By the way, Silicon Valley Clear Energy could be a well-known title to common readers of this web site. In addition to being amongst California’s CCAs that are signing contracts for energy from clear energy sources, particularly solar-plus-storage, at a significant scale, SVCE can also be amongst a bunch of CCAs which have signed contracts for large-scale, long-duration energy storage (LDES) sources.

Two lithium-ion battery storage projects, each with a duration of eight hours, shall be constructed to assist the CCAs meet procurement objectives for LDES mandated by the California Energy Fee (CEC), designed to assist the state ensure reliable electricity supply and to come online for the 2025-2026 timeframe.  

SVCE’s Don Bray mentioned the settlement with Google is for sources that shall be constructed with the search engine firm’s CFE necessities in thoughts.

“As such, contracts signed by means of CC Energy [the group to which SVCE belongs] for long-duration storage is not going to be used to satisfy Googles 24×7 objectives,” Bray mentioned.

Nevertheless, SVCE and Google will, Bray mentioned, “decide how or when to finest incorporate long-duration storage over the subsequent 5 to 10 years,” into the settlement.

Earlier this yr, Google, together with Microsoft and different main corporates, became members of the global Long Duration Energy Storage Council (LDES Council).
