E.ON plans EUR 40 billion grid investment as solar and heatwaves reshape Europe

SolarQuarter reports that E.ON plans to invest around EUR 40 billion in its European grid business by 2030 to improve reliability, flexibility and climate resilience. The company says prolonged sunshine and heatwaves are changing distribution-grid dynamics by lifting solar PV output while air-conditioning and other cooling loads raise local electricity demand. The investment case matters for solar because grids, sensors, smart substations, storage, EV charging, heat pumps and demand response are becoming core infrastructure for absorbing distributed PV growth.
