Spain needs 15-20% firm power capacity even in high-renewables scenarios, GE Vernova analysis finds

By Public Technologies
  • GE Vernova analysis published Oct. 15, 2026, finds Spain can achieve net-zero electricity by 2050 through pathways with significantly different costs.
  • Electricity demand is projected to grow around 60% by 2050, increasing pressure on grid infrastructure and system flexibility.
  • Wind and solar capacity could reach 150-250 GW, but even the most renewable-heavy scenarios require 15-20% firm, dispatchable capacity for reliability.
  • Renewables supplied nearly 57% of Spain's electricity in 2025; their share is expected to exceed 80% by 2030.
  • Coordinated investment in transmission, storage and system services is needed to limit renewable curtailment as generation becomes more geographically concentrated.
