Transformers: rise of the beasts?
…The physics of power distribution and transformers are explained on pages 2-6. What is changing in the energy transition is that renewables and EV chargers are being added to the…
Transformers: rise of the beasts?
A transformer is needed to step the voltage up or down at every inter-connection point in the grid. Hence this 14-page note explores how renewables and EVs will expand future…
Transformer shortages: at their core?
…Europe). The central argument in our 2021 report was that the total capacity of transformers would double or more, and the number of transformers needed in the power grid could…
Transformer costs: the economics?
…step up or down the voltage at every inter-connection point in the grid, to an exact, pre-specified level. The demand for transformers grows by 2.5-3x in capacity terms and by…
MOSFETs: energy use and power loss calculator?
…at low-medium voltage then using transformers to step up the power for transmission; or conversely using transformers to step down the voltage for manipulation via power electronics modules. https://thundersaidenergy.com/2021/08/19/transformers-rise-of-the-beasts/ https://thundersaidenergy.com/downloads/wind-turbine-generators-dfigs-or-rare-earth-magnets/…
Power distribution: the economics?
…Checkout Added to cart Power grids move electricity from generation sources, through the high-voltage transmission network (120-500kV), stepping down via transformers to the medium voltage grid (35-120kV) and then finally…
Grid-scale battery costs: $/kW or $/kWh?
…AC electricity to whatever level is required by the specific grid loop downstream. Transformers are sized in kW terms, and priced in kW terms. https://thundersaidenergy.com/2021/08/19/transformers-rise-of-the-beasts/ A physical connection is then…
Power grids: opportunities in the energy transition?
…But we are more worried about bottlenecks in copper (where total global demand trebles) and silver. (8) Transformers and specialized switchgear are needed to step the voltage up or down…
Renewables: how much time to connect to the grid?
…transformers, various batteries. Other technical papers have also raised the issue of rising interconnection times and power grid bottlenecks for wind and solar. And the US’s Lawrence Berkeley National Laboratory…
Transformer shortages: at their core?
Transformers are needed every time voltage steps up or down in the power grid. But lead times have now risen from 12-24 weeks to 1-3 years. And prices have risen…
