Stable, not volatile: How battery storage shapes electricity prices The energy transition is facing a new challenge: rather than being determined by the total amount of energy generated, supply security is now dependent on its flexibility. The availability of electricity increasingly depends on when and where it is fed into or extracted from the grid, rather than on its overall production alone, writes Philipp Merk, founder and managing director of Kyon Energy.

Optimal solar-plus-storage sizing for heavy industry operation Australian researchers developed a high-resolution energy modeling framework to assess how PV and batteries can supply 24/7 electricity to heavy industries, considering cost, grid interaction, and load flexibility. They found that, while technology cost reductions help, smart grid integration and flexible industrial operations are far more effective in lowering electricity costs and enabling 100% renewable energy use.
