About us
Storinum was founded to fix one of the biggest gaps in clean energy: project execution. Technology is ready, markets are open, but delivery keeps falling short. Projects stall in scope disputes, cost overruns, and coordination breakdowns.
We built Storinum to change this. We are an independent consultancy and execution platform. We don’t sell hardware or lock clients into bundled contracts. Instead, we create a clear, data-driven plan, run structured tenders with transparent comparisons, and manage delivery through a single accountable process.
Every Storinum project connects three layers:
- Energy strategy – site-specific modelling of loads, tariffs, and market opportunities.
- Execution platform – one contract, 40+ vetted partners, real-time cost and milestone tracking.
- Asset management – ongoing O&M and market participation to keep assets delivering value.
