Portfolio Assessment for Public Solar Infrastructure
Review of candidate sites, prioritization framework, system typologies, cost assumptions, and implementation phasing.
- Client type
- Government entity / development partner
- Decision supported
- Program scale-up planning.
- 01
Assessed a multi-state candidate list of public infrastructure sites for solarization investment.
- 02
Built a transparent prioritization matrix and an investment model the client team could re-run as assumptions changed.
- 03
Phased roadmap let the client commit to a credible first wave without locking in later decisions prematurely.
Context
The client held a long candidate list of public infrastructure sites — health, water, administrative — and needed a defensible way to choose what to fund first under a constrained budget envelope.
Approach
We standardized site data, scored each candidate against criticality, technical readiness, implementation risk, and O&M sustainability, and grouped them into system typologies. The investment model was built so the client team could maintain it, not as a black box.
Findings
Roughly a third of the candidate list was not ready for solarization within the program horizon — usually because of unresolved tenure, structural, or operational issues. Surfacing this early protected the budget envelope for sites that could absorb investment well.
Recommendations
A prioritization matrix, three rollout waves with site lists and budget envelopes, a maintainable investment planning model, and a set of pre-investment actions for the sites parked for later waves.
- A prioritization framework is most useful when it tells you what not to fund yet.
- The investment model has to live with the client, not the consultant.
- Deferred sites need a written pre-investment action list, otherwise they reappear unchanged.
