Pumped Hydro System Design Optimizer
Optimize pumped hydro storage designs for efficiency, cost, and compliance
What You Can Do
You can systematically evaluate pumped hydro design trade-offs by modeling round-trip efficiency across pump, turbine, and auxiliary equipment losses; validating civil feasibility through reservoir volume, dam height, and geotechnical constraints; calculating levelized cost of storage (LCOS) with detailed capital cost breakdowns; screening environmental and regulatory risks early; and matching turbomachinery types to your site's head and flow characteristics. This enables you to compare multiple design configurations during feasibility phases and identify cost drivers before committing to detailed engineering.
Features
calculates combined pump, turbine, and parasitic losses to determine net storage capability
validates reservoir volumes, dam heights, excavation requirements, and geotechnical constraints against site topography
breaks down capital costs by subsystem and computes $/MWh with sensitivity modeling
flags water rights, fish passage, seismic, and permitting risks before detailed studies
matches pump and turbine types (centrifugal, radial, Pelton, Turgo) to operating head and flow ranges
assesses third-party proposals against design specifications and performance curves
tests cost and efficiency sensitivity to reservoir size, gross head, and equipment selection changes
evaluates 3–5 candidate locations or configurations against common metrics
Example Output
Example 1: Feasibility Phase Comparison
Site A vs. Site B Analysis:
- Site A: 150m head, 50 MW capacity → Round-trip efficiency: 78.2% | LCOS: $142/MWh | Environmental risk: Moderate (fish passage)
- Site B: 200m head, 50 MW capacity → Round-trip efficiency: 80.1% | LCOS: $128/MWh | Environmental risk: Low
- Recommendation: Site B preferred; 2% efficiency gain + $14/MWh cost reduction justify permitting timeline
Example 2: Equipment Sensitivity Analysis
Turbine type impact on 100 MW / 300m head project:
- Pelton wheel: 91.5% efficiency, $18M equipment cost
- Centrifugal (multi-stage): 89.2% efficiency, $14.2M equipment cost
- Trade-off: Pelton adds $3.8M capex but recovers through 2.3% efficiency gain over 30-year asset life
Example 3: Cost Breakdown (150 MW, 250m head)
- Civil works (dams, tunnels): $420M (58%)
- Electromechanical equipment: $210M (29%)
- Balance of plant & control: $70M (10%)
- Land & permitting: $35M (3%)
- Total capex: $735M | LCOS: $135/MWh
