Re: Local generation
If you dig a little deeper you'll see that those five interconnections provide a maximum of 1100 MW to the Texas grid, while the interconnections within the two big grids are orders of magnitude larger.
Not sure what the reason is behind the existence of this small number of low capacity (and in at least one case, not really even used) interconnections. Maybe they supply power at the 'edges' where the Texas grid borders the main grids...
