- Ignoring the capital expenditure and operational costs associated with battery storage.
- Suggesting a split budget that results in neither project achieving full ROI
- Focusing only on one aspect of differentiation (e.g., just price) without a holistic view.
- Underestimating the importance of ancillary services or amenities at charging locations.
