Electromobility and the German Electric Grid

Having recently been reading about models of the US electrical grid, so made me think of how such mobility will be handled.  How much more infrastructure? Learnings for US and elsewhere? 

The impact of electromobility on the German Electric Grid    Article (9 pages) in McKinsey 

Estimates indicate that eight million electric vehicles could be on the roads in Germany by 2030. Investing in fast-charging stations and managed charging will be key to upgrading infrastructure.

With a share of almost 20 percent, the global transport sector is the third-largest contributor to CO2 emissions after electricity generation and industry. Despite vast improvements in the energy efficiency of vehicles, greenhouse-gas (GHG) emissions in the sector have more than doubled since 1970. In Germany, for example, there were 71 percent more trucks and 31 percent more cars on the road in 2019 than 30 years earlier, and a trend toward larger, heavier, and more powerful vehicles offsets gains in energy efficiency. In fact, 95 percent of new vehicles in 2019 still used gasoline or diesel.1

As Europe’s largest national economy, Germany can play a significant role in reducing emissions. In accordance with the Paris Agreement, which aims to limit global warming to 1.5 degrees Celsius and achieve climate neutrality by midcentury, Germany has committed to reducing CO2 emissions by 55 percent by 2030.2 While the country has made a solid start, current reductions will clearly not be enough. By 2030, emissions from the transport sector in Germany must be reduced by 42 to 44 percent.3

Electromobility fueled by green energy is one way to reach these reduction targets. Grid operators (both distribution and transmission) and regulators are engaged in a wide-ranging discussion on how to increase electric capacity to scale electromobility. Successful grid integration is a central component for the future ramp-up of electromobility and sector coupling, which refers to the integration of energy supply and end uses. However, significant risk must be mitigated, primarily for grid balance. For example, the rapid proliferation of fast charging will likely increase the impact of newly occurring loads from unmanaged charging of electric vehicles (EVs)....  '
