Changes in values were introduced in the datasets of Ecoinvent. By copying an existing process in the Ecoinvent datasets, values appropriate and representative to Lebanon are then introduced/changed. Irrelevant sub-processes are deleted. The final result preserves of the integrity of the original dataset while the values are "localised" to reflect the local conditions. 

For the NPV and LCOE calculations, once the capital expenditure (CAPEX) and operating expenditure (OPEX) are determined, the discount rate and lifetime were chosen based on the technology. The formula for calculating both the LCOE and the NPV were then introduced in the MS Excel spreadsheet and calculations executed.
