A Phased, Open-Source SCADA Framework for Real-Time Grid Stability in Nigeria

Nigeria's national grid collapsed twelve times in 2024 alone, and further failures continued through 2025 and into 2026, imposing costs the World Bank estimates at roughly $29 billion a year, a figure equivalent to about ten percent of the country's GDP. A recurring feature of these incidents is that the Transmission Company of Nigeria (TCN) and its regional dispatch centers largely operate without full real-time supervisory visibility, so faults that begin as localized disturbances cascade into nationwide blackouts before operators can intervene. This paper argues that grid collapse in Nigeria is not an inevitable consequence of an aging network but a symptom of a monitoring and control gap that can be closed. It proposes a three-phase, open-source Supervisory Control and Data Acquisition (SCADA) framework built on Remote Terminal Units (RTUs), Phasor Measurement Units (PMUs), the Open Phasor Data Concentrator (OpenPDC), and Rapid SCADA, deployed first as a centralized pilot along critical Lagos-Abuja transmission corridors, then decentralized into six regional control centers, and finally extended with automated generation control, voltage control, and special protection schemes. Unlike proprietary SCADA suites that can cost upward of $180 million, the proposed architecture reuses existing NETAP fiber infrastructure and open-source software to bring deployment cost within reach of Nigeria's power sector budget, while aligning with Nigerian Electricity Regulatory Commission (NERC) real-time monitoring directives and international standards including IEC 61850 and IEEE C37.118. The paper concludes with a cost-benefit rationale and a projection of how phased implementation could reduce annual grid collapses from a 2024 baseline of twelve toward a small, manageable residual number.
