The Challenge

Narrowing a national landscape to bankable development sites

Our client, a renewable energy developer, sought to identify optimal locations for pumped storage hydropower capacity as part of a broader clean energy transition. With 100+ candidate sites identified from satellite and topographic data, they needed rigorous commercial and technical due diligence to determine which locations warranted capital allocation.

The engagement required building a full screening infrastructure from scratch: scoring methodology, cost models, risk frameworks, and a site registry that could support investment committee decision-making.

Geospatial Analysis

National site mapping and viability scoring

Interactive mapping of candidate locations with elevation, water access, and grid proximity data layers, scoring each site against our proprietary viability framework.

Our Approach

From satellite data to investment-ready shortlist

We combined geospatial analysis, engineering cost models, and commercial due diligence into a structured multi-phase screening process.

01

Satellite & Topographic Scan

Leveraged remote sensing data, DEM models, and hydrological databases to identify 100+ candidate locations meeting minimum elevation and water criteria.

02

Multi-Criteria Scoring

Built a weighted screening framework across 8 diligence dimensions, balancing technical feasibility, environmental risk, grid access, and development economics.

03

CAPEX & Feasibility Modeling

Developed bottom-up cost models for shortlisted sites, benchmarked against international PSH comparables to validate investment thesis and risk-adjusted returns.

04

Investment Committee Package

Delivered a structured site registry, risk matrices, and prioritized shortlist enabling the sponsor to advance sites into pre-development with confidence.

Screening Framework

Weighted scoring across 8 diligence criteria

Each candidate site was evaluated against a proprietary scoring framework, weighting technical feasibility, environmental risk, and development economics.

CriterionWeightThreshold
Elevation Differential20%> 300m head between reservoirs
Water Availability18%Perennial water source within 5km
Grid Proximity15%< 25km to high-voltage transmission
Geological Stability14%Low seismic risk, competent bedrock
Environmental Sensitivity12%Outside protected zones & habitats
Land Accessibility10%Road access, < 15km from highway
Community Impact6%Minimal displacement, local support
Permitting Complexity5%Clear regulatory pathway
Site Registry

Structured database of evaluated sites

Each site was cataloged with technical specifications, estimated capacity, indicative CAPEX ranges, and a composite feasibility score driving shortlist decisions.

Outcome

From 100+ candidates to investment-ready shortlist

Delivered a complete diligence package including the site registry, CAPEX models, risk matrices, and a prioritized shortlist of development-ready locations. The work product enabled the client to advance multiple sites into pre-development, securing initial land options and beginning environmental impact assessments.

The screening methodology and registry framework have since been adapted for deployment in additional markets.
