  1. 1Brief
  2. 2Project-level model
  3. 3Investor materials
  4. 4Insight

We built a project-level model covering capital costs, savings for customers, financing and maintenance, with scenarios for battery prices and tariffs. The model separated proven assumptions from pilot data and those still to be tested, and included sensitivity analysis on key drivers. We also prepared a short investor memo explaining customer economics in plain language.
