Yes. Growing anything but very shade loving plants requires about 1.5 million watts in LEDs per acre. That is why most demos use lettuce, it will grow in abyssal lighting conditions and only requires a tiny amount of nutrients since it is all leaf with a like 90% water content.
These vertical farms will require dedicated nuclear and fusion reactors if they ever catch on. After all they are ditching the free fusion reactor we call sun.

An acre is ~4000m². For tomatoes and peppers 200W/m² is possible.
Still 800kW, but a lot less than you are saying.
