Read the passage below carefully:
Paragraph 1
For decades, electricity generation across West Africa has suffered from severe structural fragmentation. Individual nations have historically relied on isolated, small-scale thermal power plants fueled by expensive imported diesel or heavy fuel oil. This fragmented operational model has not only resulted in some of the highest electricity tariffs globally but has also severely crippled industrial productivity, leaving millions of household consumers subject to frequent and prolonged grid outages.
Paragraph 2
To overcome these systemic constraints, regional stakeholders established interconnected cross-border power transmission networks designed to pool diverse energy resources. By transmitting surplus hydroelectric power from water-rich nations to regions heavily dependent on thermal generation, the integrated power pool aims to balance regional supply deficits, optimize generation costs, and significantly improve baseline reliability for commercial and residential consumers alike.
Paragraph 3
Despite the clear economic rationale for power integration, structural financial imbalances and regulatory friction continue to hamper progress. National power utilities frequently struggle with sovereign debt accumulation, currency illiquidity, and unaligned tariff structures across borders. These systemic liabilities deter private investment and lead to recurring payment defaults among trading utilities, threatening the financial sustainability of cross-border power purchase agreements.
Paragraph 4
Securing the long-term viability of the regional power market requires decisive policy intervention aimed at structural reform. Governments must prioritize the creation of an independent regional regulatory body with authority to enforce unified tariff mechanisms and contractual compliance. Furthermore, establishing credit-enhancement instruments will be critical to mitigating sovereign default risks and attracting the private capital necessary to expand renewable energy infrastructure.
Based on the passage above, match each paragraph (Paragraphs 1–4) to its primary central argument.
- Paragraph 1Widespread energy insecurity and high operational costs in the region stem from national reliance on isolated, high-cost thermal generation.
- Paragraph 2Cross-border grid integration provides a mechanism to reduce electricity costs and enhance supply reliability by sharing regional power resources.
- Paragraph 3Unresolved financial debts and regulatory discrepancies cross-nationally threaten the solvency and operational stability of regional power trading.
- Paragraph 4Sustained grid integration requires unified regulatory enforcement and financial risk-mitigation measures to incentivize private investment.
