One‑Year Anniversary of the Iberian Blackout: What Happened?On 28 April 2025 Spain and much of Portugal experienced a continent‑shaking blackout that halted metros, fuel pumps and mobile networks. The event sparked a fierce debate about whether renewable energy or a lack of grid “inertia” was to blame.Grid Failure Rooted in Voltage Governance, Not Renewable InertiaThe final ENTSO‑E report identified a “perfect storm” of governance failures, especially around voltage control. Excessive or insufficient voltage caused generators to disconnect, triggering a cascading collapse. The investigation cleared solar and wind of any direct fault.Voltage mis‑management was the primary technical trigger.Regulatory limits had previously restricted wind and solar from providing voltage services.Post‑blackout reforms now allow renewables to participate in real‑time voltage control.Solar Capacity Jump: 13.8 GW Added in 2025According to Ember, Spain installed 13.8 GW of new solar capacity in 2025, up from 12.3 GW in 2024. July 2025 marked the country’s highest‑ever monthly capacity addition.Solar growth contributed to a 40 % reduction in wholesale electricity price exposure to gas in early 2024.Gas‑fired generation rose modestly in “reinforced mode” to aid voltage stability, but accounted for only half of the 2025 increase, the rest reflecting lower wind and hydro output.Average power price in March 2026: €43/MWh, the third‑lowest in Europe.Renewables Shield Spain from Gas Price Shock and Shape Future Energy PolicyAmid the 2026 Middle‑East conflict and soaring gas prices, Spain’s renewable base insulated consumers. Analysts note that without recent wind and solar growth, electricity prices would have been 40 % higher in the first half of 2024.Spain’s power price is roughly half of Germany’s (€99/MWh) and one‑third of Italy’s (€144/MWh).Regulatory change in April 2026 now permits >50 % of renewable plants to provide voltage compensation services.Experts stress that disinformation about renewable insecurity has collapsed, reinforcing policy support.What’s Next for Spain’s Power System? Toward Real‑Time Voltage Control and StorageFuture priorities include scaling large‑scale lithium‑ion battery storage and expanding renewable‑based voltage services. Chris Rosslowe of Ember predicts continued acceleration of non‑fossil generation, while José Luis Rodríguez warns that protecting the grid from gas price volatility will remain a driver for further renewable investment.Deploy grid‑scale batteries to replace the “heartbeat” previously provided by coal and gas turbines.Complete integration of renewable plants into voltage control markets by 2027.Monitor gas‑price trends to ensure renewables remain the cost‑effective backbone of Spain’s electricity system.

Australia's Prime Minister, Anthony Albanese, has stated that the country is prepared to provide assistance in the Strait of Hormuz, a crucial route for oil shipments, as global oil prices experience a significant drop. On Saturday, oil prices fell by approximately 10% after Iran announced that the strait would be open for commercial vessels during a ceasefire with the United States and Israel.The Prime Minister was attending a meeting of 49 countries to discuss the reopening of the strait when the news broke. Albanese emphasized the importance of freedom of navigation for global trade, stating, “Freedom of navigation is essential for global trade.” He also expressed the desire for a permanent and full reopening of the strait for all countries.Australia's energy minister, Chris Bowen, reported that the country has 46 days’ worth of petrol in reserve, which is 10 more days than before the US and Israeli bombing of Iran that sparked the global fuel crisis. Since April 1, fuel prices at Australian pumps have fallen by about 10c per litre beyond the artificial measures to ease prices.The NRMA spokesperson, Peter Khoury, mentioned that it could take a week for the falls in global oil prices to translate to lower prices at the fuel pumps. He also noted that the national average for unleaded petrol has fallen 50c since April 1, and diesel has fallen 37c in the last week.Additionally, the Australian Competition and Consumer Commission reported that average retail petrol prices had dropped 41.6c per litre since March 31 across major cities. The federal government's measures, including halving the fuel excise on petrol and diesel and pausing GST revenue on fuels, have resulted in a saving of about 32c per litre of fuel.
