Grant Overview

The U.S. Virgin Islands electric system operates two isolated grids on St. Thomas-St. John and St. Croix, each dependent on imported fuel delivered by barge. Current dispatch relies on manual spreadsheets updated hourly, creating a 90-minute lag between fuel-price changes and generation adjustments. This operational structure prevents precise forecasting of solar output on installations exceeding 5 MW on each island.

St. Thomas Water and Power Authority and the Virgin Islands Water and Power Authority face these constraints across 133 miles of overhead and submarine cable. Commercial ports on St. Croix and tourism facilities on St. John record voltage deviations that exceed 5 percent on 12 percent of days, directly affecting desalination plant operations that supply 70 percent of potable water.

The grant supports replacement of legacy dispatch software with platforms that ingest real-time SCADA feeds and ocean-temperature data for improved unit commitment. Eligible operators must demonstrate that new systems will reduce fuel-burn variance by at least 8 percent within 18 months using verified meter data.

Unlike Puerto Rico's centralized utility, the Virgin Islands requires separate optimization modules for each island's isolated system because no inter-island transmission exists.

Operational Requirements in the Virgin Islands

Applicants must submit 2022-2024 fuel-consumption logs and confirm integration with the Public Services Commission's quarterly reporting format. Budget narratives must itemize costs for marine-grade hardware rated for Category 5 wind loads.

Infrastructure Constraints in the Virgin Islands

Submarine cable capacity between St. Thomas and St. John limits data throughput to 50 Mbps, requiring edge-processing nodes on each island rather than a single mainland-style data center.

Readiness Requirements in the Virgin Islands

Projects must include contingency plans for 10-day fuel-supply disruptions and maintain offline decision-support tools during communication outages.
