This are end-user-prices, but the website is about wholesale prices which are normally much smaller e.g. in 2020 the wholesale average had been around $38/MWh (the price companies selling electricity to end-users and companies pay). Also note that the site contains not just "real-time" prices but also day ahead prices (selected by default) which due to instabilities are quite a bit higher then real-time prices.
