End-of-Life Management of Power Generation Assets: Nigerian Perspective

25% by installed capacity of grid-connected power plants in Nigeria are already close to their end of life. This phase of asset life cycle is characterized by continuous and rapid increase in equipment failure rate (λ), maintenance cost and power generation/sales deferrals due to plant downtime. This phase corresponds to the positive slope of a bathtub curve. These factors make Asset End-Of-Life (EOL) expensive to finance. This is compounded by Nigeria's cost non-reflective electricity tariff, delayed invoice payments to market participants by the Nigerian Bulk Electricity Trading Plc (NBET) and the power sector's overall negative cash-flow. This paper examines the challenges associated with managing end-of-life phase of Nigeria's power generation assets; and proffers solutions to them. Market operators, investors, regulators and consumers will find the paper useful for managing their interests in Nigeria's power generation market.
