To be fair: grid buildout is quite expensive.

A comparison: the giant Dogger Bank offshore wind farm project (multi-GW) cost somewhere in the $10bn range. On the other hand, Germany calculates with >$100bn for grid buildout within the next decade (https://www.netzentwicklungsplan.de/sites/default/files/2023...).

Also, having customers that rely on your grid but buy very little of your power is simply unappealing for operators, so I would assume that their pricing tries to disincentivise as much as possible (=> "they gonna overcharge you for the grid connection").

The not-so-hidden costs of collecting extremely diffuse wind / solar is the elephant in the room 10x bill for the supporting grid infrastructure.

Nuclear advocates, like myself, claim drop in replacement nuclear power reactors at existing coal / gas sites would largely obviate this.

Even adding new nuclear power reactors at greenfield sites would constitute a significantly reduced grid build cost, as the power is highly concentrated.

And nuclear is so say that nuclear power reactors employees are routine exposed to less radiation at work than they are at home in their kitchen with granite bench tops.
