I wasn't able to find the right data to compare it to but it seems to be roughly over 5 time the price compared to Germany and Germany has some of the highest electricity prices in Europe. I.e. compared to some of the Countries with the cheapest electricity in the EU it's something like 15 times the price.

In 2020 the highest wholesale electricity price spike in the US seem to have been $127/MWh with an average of $38/MWh.
