Choose the right perspective

Questions to take into the conversation
- 01How do you forecast costs and margins on storage projects when battery prices and delivery schedules move?
- 02How are battery storage deployments financed, and which numbers do lenders and investors focus on?
- 03What finance processes did you build first as the storage business grew, and why those?
