Long-term least-cost electricity capacity expansion model for Ghana (OSeMOSYS) NDC pathways, fossil phase-out sensitivity, green jobs # Ghana Electricity System Model — Long-Term Capacity Expansion (OSeMOSYS) Least-cost capacity expansion model of Ghana's electricity system to 2055, built in **OSeMOSYS** (Open Source Energy Modelling System). The model evaluates Ghana's pathway options against its NDC commitments and net-zero 2060 target across three scenarios, with sensitivity analysis on technology costs and a green jobs assessment. > Developed as part of *MJ2380/MJ2381 Energy Systems Analysis* at KTH Royal Institute of Technology (2025), in a four-person team. My contributions: background research and problem identification, factsheet development and key assumptions, scenario modelling with sensitivity analysis, policy analysis and recommendations. 📄 **Full project fact sheet (PDF)** *Figure 2 — Electricity production by technology under the NDC scenario, 2024–2055.* --- ## Research questions 1. What are the least-cost electricity pathways for Ghana under different policy and demand scenarios? 2. How can renewable integration be optimised to meet demand growth while reducing emissions? 3. What are the implications of different investment strategies for energy access, reliability, and sustainability? ## Model overview | Attribute | Detail | |---|---| | Framework | OSeMOSYS (linear programming, perfect foresight) | | Scope | Ghana power sector, single-node | | Horizon | 2024–2055 | | Technologies | Hydro (2.48 GW existing), natural gas, waste-to-energy, solar PV, onshore wind, nuclear (NDC scenario) | | Constraints | Renewable resource potentials, proven oil/gas reserves, capacity limits | | Calibration | Ghana Energy Commission 2023 Energy Outlook, IRENA, World Bank Africa Energy Outlook | ## Scenarios | Scenario | Question it answers | Key assumptions | |---|---|---| | **1 — Business as Usual** | What happens if current trends continue? | Capacity limited by resource potentials and proven reserves; no storage; declining solar/wind costs | | **2 — NDC** | Can Ghana meet its 2030 emi …
