How Portuguese companies can cut their electricity bill — and how much they can save

Portugal has one of the highest tax burdens on business electricity in Europe. For SMEs, more than half of the bill consists of charges unrelated to actual consumption.
ADENE and DGEG studies indicate that Portuguese SMEs have an average savings potential of 20% to 40% on electricity bills.
Why is the electricity bill so heavy?
- Energy Tariff (TE) - The actual cost of energy consumed.
- Network Access (TAR/UUR) - Remunerates electrical infrastructure.
- Taxes and charges - 23% VAT, CESE, CIEG. Often 40–55% of the total.
- Time-of-use and power - Off-peak consumption can reduce costs by 30–50%.
The 8 highest-impact measures
- LED Lighting - up to 80% savings on lighting.
- HVAC with Inverter - up to 40% on air conditioning.
- Solar PV - 30–60% of total.
- Free Energy Market - 10–25% on energy tariff.
- IoT Monitoring - 5–15% of total.
- Power factor correction - up to 10%.
- Automation - 5–12% of total.
- IE3/IE4 equipment - 10–30% on motors.
