What measures has Red Eléctrica implemented to prevent future outages, and what are the associated costs?

Red Eléctrica's response to the outage involves increased use of adjustment services to ensure supply stability, leading to a surge in costs reflected in consumer electricity bills. The cost of these adjustment services has risen from an average of €14.2 per megawatt-hour in May 2024 to €24.69 this May, with hourly values exceeding €44/MWh. This increase is largely due to 'technical restrictions', where Red Eléctrica manages generation to maintain grid stability.

What is the primary challenge posed by Germany's rapid renewable energy expansion, and what are the immediate economic consequences?

Germany's rapid renewable energy expansion, exceeding 60 percent of electricity generation from wind and solar in 2024, is hampered by insufficient grid capacity. This necessitates large-scale battery storage to manage energy surpluses and prevent grid overloads, costing over €1 billion in 2024 due to energy losses from curtailment.
