of approximately 55 MW, and a minimum load of about
35 MW. Although the topography of the ocean floor has prevented the direct interconnection of these two grid systems
to date, studies are underway to examine the possibility of
connecting both island systems with Puerto Rico and the
British Virgin Islands (Figure 4). The grid infrastructure of the
U.S. Virgin Islands consists primarily of subtransmission
lines (25-115 kV). The two grid systems currently operate at

St. Thomas and St. John are part of one interconnected power
system, with an installed capacity of 191 MW, a maximum
load of approximately 88 MW, and a minimum load of about
50 MW. The island of St. Croix constitutes a second power sys-
