GREAT ARTICLE – THANKS.Blanca you asked for info about electric rates – vazio etc. I found this other article which was very helpful. https://lojaluz.com/faq/tarifas/ciclos-horarios/horas-vazio essentially Cheio is the absolute cheapest rate – for those hours demand for electricity is at its lowest.I then went to EDP website and there is a ’function’ whereby you can enter the type of contract you want – daily or weekly / bi or tri hourly rates and it gives you actual cost values per Kwh.I hope this is of help/use to your readers
