It operates using two reversible pump-turbine units, each generating  225 MW} of peak capacity to quickly supply the regional electrical grid during high-demand periods.Reservoir Capacity Comparison: Taum Sauk Upper Reservoir vs. Victoria Reservoir (Sri Lanka)<table style='width: 100%'><tr><td>Metric</td><td>Taum Sauk Upper Reservoir (USA)</td><td>Victoria Reservoir (Sri Lanka)</td><td>Comparison / Ratio</td></tr><tr><td>Type</td><td>Closed-loop Pumped-Storage Upper Basin</td><td>Conventional Multi-purpose Reservoir</td><td>N/A</td></tr><tr><td>Gross Storage Capacity</td><td>~5.37 million m³ (4,350 acre-feet)</td><td>722 million m³</td><td>Victoria is ~134x larger</td></tr><tr><td>Active Storage Capacity</td><td>~5.37 million m³</td><td>689 million m³</td><td>Victoria is ~128x larger</td></tr><tr><td>Surface Area</td><td>0.22 km² (54.5 acres)</td><td>22.7 km²</td><td>Victoria is ~103x larger</td></tr></table>Daily Generation Limits�<table style='width: 100%'><tr><td>Metric</td><td>Taum Sauk Plant</td><td>Victoria Power Station</td></tr><tr><td>Installed Capacity</td><td>210 MW (3 × 70 MW units)</td><td></td></tr><tr><td>Theoretical Daily Limit</td><td>3,600 MWh per full reservoir discharge cycle (8 hours max continuous run at full load).</td><td>5,040 MWh if run continuously at 210 MW for 24 hours.</td></tr><tr><td>Primary Operational Constraints</td><td>High dependency on water volume limitations of upper reservoir (8-hour hard wall per pump cycle).</td><td>Managed around downstream irrigation demands (Mahaweli Authority) and rainfall inflows.</td></tr></table>[td)450 MW (2 × 225 MW units)[/td]Real Generation<table style='width: 100%'><tr><td>Metric</td><td>Taum Sauk Plant</td><td>Victoria Power Station</td></tr><tr><td>Average Annual Output</td><td>Net-negative energy producer due to ~70% round-trip pumping efficiency.</td><td>~780 GWh annually.</td></tr><tr><td>Real Daily Generation</td><td>0 to 3,600 MWh.
