What is holding back electrification's share of US energy consumption?
Core argument: US transformer delivery times have stretched from 4–6 weeks in 2019 to 2–3 years, straining a grid that relies on roughly 70 million transformers requiring special steel to limit power losses.
Remember this key aspect of the energy transition: until an energy use is electrified, it’s hard to decarbonize it using green grid electrons. And while grid decarbonization is continuing at a steady pace, the US has made little progress increasing the electricity share of final energy consumption. One major obstacle: transmission line growth is stuck in a rut, way below DoE targets for 2030 and 2035. Another obstacle: shortages of transformer equipment, whose delivery times have extended from 4-6 weeks in 2019 to 2-3 years. Around 70 million transformers step voltages up and down across the US grid and require special steel to reduce power losses. Half of all US transformers are near the end of their useful lives and will need replacing, along with replacements in areas affected by hurricanes, floods and wildfires. Transformer manufacturing investment by Schneider Electric and Hitachi North America should help, eventually.
