ERAA 2021: Executive Report
The ERAA 2021 is divided into eight documents (Executive Report and Annexes) to facilitate readers in identifying relevant information. The executive report describes the ERAA 2021 motivation followed by the adequacy results for the national estimate scenarios and central reference scenarios:
- National Estimate for target year (TY) 2025 and TY 2030, as collected from TSOs;
- Central Economic Viability Assessment (EVA) without Capacity Mechanism (CM) for TY 2025: based on “National Estimate” scenario and updated through the application of an EVA without CM;
- Central EVA with CM for TY 2025: based on “National Estimate” scenario, and updated through the application of an EVA with CM;
- National Estimate with Low Thermal Capacity for TY 2025 & TY 2030, scenario with reduced thermal capacity collected from transmission system operators (TSOs).
