SAN JOSE \u2014 PG&E has doubled the size of one of its San Jose substations, an electricity hub that\u2019s poised to expand even more to meet the tech industry\u2019s hunger for energy.<\/p>\n

The utility titan\u2019s Santa Teresa Substation is the site of the recently completed expansion and of anticipated future growth, according to PG&E.<\/p>\n

The total capacity of the South San Jose substation is now 80 megawatts following the expansion that added 40 megawatts of capacity, PG&E spokesperson Stephanie Magallon said. The station is at 6402 Santa Teresa Blvd.<\/p>\n

Oakland-based PG&E has launched efforts on multiple fronts to expand its electricity grid<\/a> to meet widening demand by tech companies and data center operators as computer processing needs intensify during the artificial intelligence revolution.<\/p>\n

In addition to PG&E\u2019s endeavors, companies such as LS Power<\/a> are adding significant new energy infrastructure in San Jose and the East Bay.<\/p>\n

The expansion capabilities of PG&E\u2019s Santa Teresa Substation are far from bumping up against a capacity ceiling, according to the company.<\/p>\n

\u201cWe made it scalable so we can easily add equipment to the substation to support additional load or other customers,\u201d Magallon said.<\/p>\n

The substation\u2019s capacity was doubled to meet a request for an additional load of 40 megawatts requested by Equinix, a global operator of data centers and digital infrastructure hubs, according to Magallon.<\/p>\n

\u201cThe expansion of the Santa Teresa Substation is significant because substations are the key connection points for new energy infrastructure,\u201d said Bob Staedler, principal executive with Silicon Valley Synergy, a land-use consultancy.<\/p>\n

The substation could do more than provide more electricity in the area, Staedler said.<\/p>\n

\u201cWhile it will support Equinix\u2019s data center development, it should also be viewed as a valuable resource for future battery storage interconnections,\u201d Staedler said. \u201cPG&E has an opportunity to demonstrate continued environmental leadership by making Santa Teresa a preferred location for battery storage projects.\u201d<\/p>\n

As part of the just-completed PG&E project, the utility installed a new 45 mega-volt ampere transformer and two 21 kilovolt circuits at the power complex.<\/p>\n

\u201cThere are plans to further expand the Santa Teresa substation in the next three years to help us meet San Jose\u2019s growing energy needs,\u201d Magallon said.<\/p>\n

The next phase would include installing a new 75 mega-volt ampere transformer, she added.<\/p>\n

\u201cThe Santa Teresa substation came online in 2022, making it a relatively new facility that was designed with future growth in mind,\u201d Magallon said. \u201cOnce the third transformer is installed, it will be fully built out.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"SAN JOSE \u2014 PG&E has doubled the size of one of its San Jose substations, an electricity hub…\n","protected":false},"author":2,"featured_media":347944,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[29],"tags":[2080,184,387,7,8,1279,383,6774,1286,181,23,100,3604,388,88,90,89,198,200,201,1970],"class_list":["post-347943","post","type-post","status-publish","format-standard","has-post-thumbnail","category-san-jose","tag-artificial-intelligence","tag-bay-area","tag-business","tag-california","tag-california-news","tag-data","tag-economy","tag-energy","tag-jobs","tag-latest-headlines","tag-local-news","tag-news","tag-pge","tag-real-estate","tag-san-jose","tag-san-jose-headlines","tag-san-jose-news","tag-santa-clara-county","tag-south-bay","tag-south-san-jose","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/347943","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=347943"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/347943\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/347944"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=347943"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=347943"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=347943"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
