ESCO performs best on NPV because the investor puts up no capital — but the investor does not acquire the asset either. Neither ownership of the installation nor its residual value at the end of the horizon remains on the investor's side.
ESCO / OPEX model
- The ESCO model engages no equity, so IRR is undefined. Comparison with an outright cash purchase does not account for the loss of asset ownership and residual value after the contract term.
