Third consecutive year of declines for Self-Consumption, with a residential and battery boom

Installed capacity in the first half of the year dropped to 611 MW (-14.6%). The blackout and lower surplus prices boosted residential installations (+11.6%) and triggered a record surge in batteries (+88%). Distributed storage is consolidating its role as a key element for household security and a lifeline for industry. With the grid at breaking point, self-consumption with storage is the only way for industry to expand its effective capacity.
