Funding & commercial models
Capital structures aligned to long-term outcomes.
From fully funded EaaS through to client-owned hybrid structures, we engineer the commercial model around your balance sheet, reporting position and strategic objectives.
Energy-as-a-Service (EaaS)
Zero capex deployment. We design, fund, install and operate the asset; you pay for outcomes — kWh, kW or guaranteed savings.
- Off-balance-sheet potential
- Outcome-based pricing
- Long-term operator alignment
Power Purchase Agreement
Long-term, indexed-price contract for on-site generation. Predictable energy cost, no upfront capital.
- 10–25 year terms
- Fixed or indexed pricing
- Generation-only or full-stack
Shared Savings
We deliver and operate the system. Realised savings are shared on an agreed split — true commercial alignment.
- Aligned upside
- Performance-linked
- No upfront capex
Joint Venture / SPV
Co-invested infrastructure with shared governance and returns. Suited to portfolio-scale and strategic capital partners.

Client-owned assets
You own the asset; Sostratus is the long-term operator and optimiser.
