China adopts tougher mandatory energy limits for polysilicon plants
China has published a stricter mandatory energy consumption standard for polysilicon production, lowering the maximum allowable energy use for existing rod-silicon plants and tightening accounting rules. The revised standard, effective Jan. 1, 2027, could significantly reduce China’s compliant polysilicon capacity, although the near-term supply impact may be limited because much of the affected capacity is already idle.

The Iberian BESS paradox
On a Monday in April 2025, 60 million people across Spain and Portugal lost power. The blackout was no minor technical accident, and it exposed the Achilles’ heel of the Iberian energy transition. The system collapsed because it lacked sufficient storage, because synchronous generators were being displaced, and because the interconnection with France remains a bottleneck.

New rules for Poland’s grid
Poland’s amended Energy Act – sometimes known as the Grid Act – came into force on April 30, 2026, introducing significant changes for grid connections to generation and storage. Poland’s Ministry of Energy estimates that the new regulations could unlock the potential to connect around 150 GW of new renewables and storage capacity. New possibilities for cable pooling have been welcomed, but asset owners also face a greater financial commitment when connections are issued and implemented. Energy law expert Piotr Mrowiec outlines the new rules and provisions.

Flexibility as an asset
The Iberian Peninsula is emerging as a key test case for hybrid PV and battery storage, driven less by inherent project attractiveness and more by mounting pressure on standalone solar. As merchant exposure, price cannibalization and curtailment risks intensify, co-located battery energy storage systems (BESS) are becoming a tool to stabilize revenues rather than unlock upside. In this context, aggregator contracts are evolving toward more flexible, merchant-driven structures. Everoze Partner Ana Bamonde explores this shift and what it means for the structuring, financing and operation of hybrid assets in Iberia.
