How to Read a Spanish Business Electricity Bill
Business energy bills in Spain (especially the 3.0TD tariff) are notoriously difficult to decipher. Here is a line-by-line breakdown of exactly what you are paying for, and how to spot hidden penalties.
Anatomy of a 3.0TD Factura
Technical Details (Datos Técnicos)
Located usually on the first page or the back page. This defines your contract limits.
Término de Potencia (Fixed Power Term)
Business.ReadBill.sections.2.description
Where businesses lose money: If you see very high identical kW values contracted across all 6 periods, you are likely overpaying. The P6 period (weekends/nights) is extremely cheap, but the P1 period is very expensive.
Término de Energía (Active Energy)
This is the actual electricity you consumed. You will see 6 different lines corresponding to the energy consumed in the 6 periods (P1 to P6), each multiplied by a different price per kWh.
Hidden Penalties & Excesses
Scan your bill closely for these two line items. If they exist, your bill is actively bleeding profit.
You exceeded your contracted kW limit in a specific period. The distributor has fined you for the spike. You must either lower your peak usage, or raise your contracted limit to stop the fines.
Your motors or refrigerators are throwing "dirty" power back onto the grid. Install a capacitor bank to eliminate this cost.
