Module 11: Power Purchase Agreements (PPAs) & Grid Codes
- Deconstructing the Kenya Electricity Distribution Grid Code and transmission network connection requirements.
- Negotiating advanced PPA clauses: Deemed Generated Energy Payments during utility-enforced curtailment, "Take-or-Pay" risk allocation, and system stability penalties.
Module 12: Interconnection Application Workflows
- The complete administrative path through EPRA (Class T3 requirements), KPLC, Ketraco, and NEMA (ESIA compliance).
The final day focuses on data-driven operations, financial stress-testing, and simulated real-world problem solving.
