Renewables reach 30GW by May 2024 surpassing coal soon. Coal production share falls below 60% in 2024. OZE targets 50GW by 2030 with more likely from solar and onshore wind. Nuclear blocks and 11GW offshore wind hit in 2030s mostly northern Poland. North generates at least 20GW new power by 2040. South consumes 70% electricity from heavy industry. Grid costs near 550B zł match 750B zł generation investments. HVDC lines cut long-distance losses and relieve AC grid. PSE plans 5,000km new lines for 64B zł by 2034. Germany failed by neglecting grids causing Polish bypass flows. UK fixed OZE queues with efficient procedures. US assesses grid upgrades before connections. North Sea hybrid grids enable 120GW offshore by 2030. War shows need for redundant paths against sabotage. Grid failure dooms energy transformation.
