In early July, analysts noted that the expansion of renewable power across the EU was being hampered by insufficient electricity‑grid capacity and a slower‑than‑expected rollout of new wind projects. By the end of the month, Portugal’s energy group EDP argued that renewables can still deliver cheaper electricity, but stressed that substantial grid upgrades and regulatory reforms are essential. EDP highlighted its growing wind portfolio in Poland—over 1 GW of on‑shore capacity and a planned 390‑MW offshore farm—while criticizing Poland’s restrictive distance‑law regime and urging faster permit approvals. The company also denied that the recent Iberian Peninsula blackout was caused by renewable generation. Together, the snapshots trace a shift from a broad view of systemic grid bottlenecks to a company‑level perspective that both acknowledges those constraints and calls for policy action to unlock further renewable deployment.

### 2026-07-08: EU renewable power expansion hindered by grid limits and slow wind growth

EU reports warn renewable growth—especially wind—lags behind 2030 targets due to grid bottlenecks, permitting delays and limited storage, while ENTSO‑E proposes new guidelines to curb forced oscillations from i
