Being next to a nuclear power plant but attached to a regional grid is not that relevant in terms of total additive emissions from a data center build out. You have to look at the change in emissions of the grid as a whole. Companies are incentivized to care about disclosing a narrow boundary view of scope 1 & 2 emissions but we live in the real world not a spreadsheet.

US electrical emissions YOY increased in part due to data center build out and energy demand.
