- philipkglass 3y agoThat's much too high an estimate, at least for the United States: How much electricity is lost in electricity transmission and distribution in the United States? The U.S. Energy Information Administration (EIA) estimates that annual electricity transmission and distribution (T&D) losses averaged about 5% of the electricity transmitted and distributed in the United States in 2018 through 2022. https://www.eia.gov/tools/faqs/faq.php?id=105&t=3 https://www.eia.gov/tools/faqs/faq.php?id=105&t=3
- kwhitefoot 3y agoThat's just outright false. Where did you get it from.
- ldbooth 3y agoI can't find a link so I'll explain it... Single high voltage transformers approach the 6-8% at full load... Not to mention the wire losses and other transformers in the system minimum 3-5). The number you quoted from the EIA is not accurate. See this Nameplate Z% (impedance aka losses) of an ABB 20MVA transformer: https://images.app.goo.gl/hXNTWAv1xnu83znQ7 https://images.app.goo.gl/hXNTWAv1xnu83znQ7 It is higher as the transformers get larger. Correction tho... 30-40% includes the losses from generation, not just T&D. And if you keep searching the EIA quoted that at 34%.
