⚠️ ACER: Grid Bottlenecks Risk EU Green Goals

ACER warns that grid congestion and project delays are threatening Europe’s energy transition. In 2024, only 54% of capacity was available on key lines (vs. 70% target), causing €4.3B in costs. Over 60% of infrastructure projects face delays. ACER urges faster upgrades and better grid use to avoid further setbacks.

🇪🇺 EU Pledges €300B for Global Renewable Push

At the Global Renewables Summit, the EU committed €300 billion by 2027 to scale clean energy in Europe and worldwide. The plan targets renewable expansion, grid modernization, and investment in emerging markets. A new Global Energy Transitions Forum was also launched to coordinate efforts.

🔋 Italy Awards 10 GWh in First Battery Auction

Italy allocated 10 GWh of battery storage in its first national auction, with Enel winning over half the capacity. Run by Terna, the auction was 4x oversubscribed, offering 15-year fixed revenues at an average of €13,000/MWh.
All projects use lithium-ion tech and must be online by 2028, totaling €1B in investment. More auctions, including hydro storage, are planned to support the energy transition.

☀️ Central Europe Emerges as Solar Leader

Once coal-dependent, Central Europe has rapidly scaled solar, growing from 5 TWh to 29 TWh between 2019 and 2024. Hungary’s solar share hit 25%, Poland’s output rose 20x, and Slovakia shut its last coal-only plant.
Backed by grid upgrades and policy reform, the region now outpaces the EU average, proving fast clean energy transitions are possible—even from coal-heavy starting points.
