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.
