Background
Frank Energy is a Dutch-founded energy retailer that brought its transparent, digital-first model to Spain. Instead of complicated tariff structures and long lock-ins, Frank keeps its offer simple: a clear price per kWh, a visible monthly fee, and no surprises buried in the small print of your factura de la luz.
Frank's indexed tariff follows the Spanish wholesale market (OMIE) with a fixed fee on top, so when market prices fall, your bill follows. That makes it a strong fit for households that use a decent share of their electricity outside peak hours — or anyone who simply wants to see exactly how their price is built up.
Because Frank supports customers in English, Dutch as well as Spanish, it is a popular choice for expats and international residents along the Costa Blanca, Costa del Sol and the major cities.
