Sustainable Asset Valuation (SAVi) of the N’Diaye Wind Farm in Senegal

The report evaluates the N’Diaye wind farm in Senegal using the SAVi tool, which incorporates externalities and climate risks into financial modelling. While traditional analysis suggests coal is the cheapest option, a holistic cost-benefit analysis reveals that wind energy is the most favourable choice due to lower environmental impacts, higher employment generation, and the avoidance of significant social costs of carbon. HFO is found to be financially non-viable across all scenarios.

• In a traditional baseline assessment (Scenario 0), coal power generation is the cheapest option with a levelized cost of electricity (LCOE) of CFA 33,452 per MWh, compared to CFA 43,337 per MWh for wind and CFA 145,659 per MWh for HFO.
• When climate risks and externalities are integrated (Scenario 2), the wind farm becomes the most favourable option; its LCOE decreases to CFA 43,266 per MWh, while coal's LCOE increases to CFA 52,998 per MWh and HFO's to CFA 155,898 per MWh.
• The wind farm is projected to generate significantly more employment than the alternatives, with at least 66 full-time equivalent (FTE) jobs per year, compared to 15 for HFO and 11 for coal.
• Implementing the N’Diaye wind park instead of HFO or coal could avoid between 2.1 million and 6 million tonnes of CO2e emissions between 2019 and 2042.
• From a financial perspective, the wind farm performs on par with coal when climate risks and externalities are considered; based on Net Present Value (NPV), the wind project (USD 157.38 million) outperforms the coal alternative (USD 129.64 million) in Scenario 2.
• HFO-fired power generation is considered financially non-viable across all modelled scenarios, with a negative NPV of approximately USD -1 billion over a 40-year lifetime.
