Uncertainty around the evolution of the wholesale market design, given the current challenges: • Marginal remuneration system not adjusted to the current context of growing penetration of fixed cost technologies (renewables, backup, storage). • Growing penetration of technologies with 0 marginal cost (reducing prices and increasing prices’ volatility). • Uncertainty around the returns of the conventional generation, in particular as backup capacity (relevant in a perspective of ensuring security of supply). • Volatile context, not suitable for long-term investments necessary to the modernization, decarbonization and security of supply.
