Behind the Meter and Beside the Reactor
Co-location is the industry's shortcut around the queue, and it is exactly as clever and as contested as shortcuts usually are. If you plant a data center next to a power plant and wire it straight to the generator, you appear to sidestep the years of transmission study that gate everyone else. But you also raise a question the grid cannot ignore: when that load leans on the shared network for backup, for reliability, for stability, is it really off the grid, or is it enjoying the grid's services without paying for them? The nuclear co-location fight taught the whole sector that there is no free lunch beside a reactor. The physics of interconnection follows you even when the wires appear to end at the fence.

Why does connecting a large load directly to a power plant, behind the meter, still raise grid-wide interconnection concerns?
Show the answer
Because a behind-the-meter load co-located with generation almost always retains some reliance on the broader transmission system, for backup when the plant is down, for frequency and voltage support, and for stability, so it continues to impose costs and risks on the shared grid. That is why regulators scrutinize whether the arrangement lets the load avoid paying transmission and reliability charges that its continued reliance on the network would otherwise require.
