What happened to Spain's electric grid?Official data shows a dramatic decline in recorded demand from 26,968 MW to under 13,000 MW within minutes (REE, Demand Graph, 28/04/2025). Full restoration of service extended into the early hours of April 29th. This incident marks one of the most significant electric grid collapses in Spain in recent decades. 2.
Why is inverter protection important in Spain?In Spain’s case, the broader adoption of inverter-based systems (virtually nonexistent in 2003) highlights the need to update or maintain protections (originally designed for local faults in MV networks) to meet today’s critical transmission system stability requirements, as well as defense plans.
How do inverters help a grid?With proper inverters, can contribute to frequency support and grid services – Provide immediate response to frequency changes – Store excess solar or wind power for use during outages or grid strain – Help form resilient microgrids in homes, farms, or industrial zones – Ensure energy independence in the face of grid instability.
How does the Spanish grid work?Voltage and reactive power control: The Spanish grid uses capacitor banks, reactor coils, and generator excitation controls to maintain voltage within limits. Voltage instability can occur if a large power transfer is suddenly lost or if there is a shortage of reactive power support, leading to voltage collapse in some areas.
Is Spain a grid starved of flexibility?Alex Schoch, former Tesla Energy executive and now head of demand flexibility at Octopus Energy, offered his analysis in the Linkedin post: “Two blackouts, one root cause. Spain 2025: a grid starved of flexibility.” According to an expert, the situation mirrors South Australia’s infamous 2016 system black event.
How has demand impacted the power grid?This rapid imbalance between generation and demand led to an immediate frequency drop and the activation of automatic protection systems across the grid. Official data shows a dramatic decline in recorded demand from 26,968 MW to under 13,000 MW within minutes (REE, Demand Graph, 28/04/202
