Your journey to energy independence
From fully grid-dependent to running your own micro-power-station. Five honest stages, what each one costs, and what each one actually gives you.
Fully grid-dependent
You buy 100 percent of your electricity from EDP. When the grid fails, you have zero power. Your bill goes up every year with tariff increases.
Grid-tied solar
Panels cover about 35 percent of your annual consumption. Bills drop, but the system shuts down during a blackout. This is the standard EDP installation.
Grid-tied + optimized
Better inverter, smart consumption shifting, maybe a small battery. You cover 55 percent of consumption. Still shuts down during a blackout.
Hybrid with battery
Solar panels plus a properly sized battery. You cover 75 percent of consumption and keep essentials running during a blackout. This is what kept lights on in April 2025.
Energy independent
Large system, battery, maybe a backup generator. You are 95 percent self-sufficient. The grid is your backup, not your lifeline. Blackouts are something you read about afterwards.
