Precio Luz • Spain electricity

Electricity doesn't cost the same at eight as it does at three. PrecioLuz colours it in, hour by hour: green, go ahead; red, better to wait. Every evening, as soon as tomorrow's prices are published, they're in the app. So you can set the washing machine, the dishwasher or the car to charge knowing what it will cost. THE PRICE AT A GLANCE • The moment you open it: the price right now, the day's average, and when the cheapest and dearest hours fall. • All 24 hours, each with its colour and its period: off-peak, mid-peak or peak. • Past days, and how the average price has moved over time. • If your tariff tracks the wholesale market, that price is there too. • With solar panels: what you're credited each hour for the power you export to the grid, and when that rate turns negative. ALERTS • Every evening, tomorrow's price for your area: the average, how it compares with today and the cheapest stretch. Just one notification a day. • If you like, another the moment power drops below the price you've marked as cheap, or climbs above the one you've marked as dear. It's worked out on your iPhone, so your limits never leave it. WIDGETS • The price right now, today's curve or the cheap hours still to come, on your Home Screen. • And the price on your Lock Screen, without unlocking your iPhone. YOUR WAY • You decide where cheap ends and dear begins, and the app and widgets colour themselves to your scale. • Choose the area your supply is in: mainland Spain, the Balearics, the Canaries, Ceuta or Melilla. WHERE THE POWER COMES FROM • Each day's generation mix: solar, wind, nuclear, combined-cycle gas, hydro and the rest. • How much of it is renewable, and how much CO₂ was emitted. • Tomorrow's wind and solar forecast, and how much of demand they'll cover. No ads, no account, no email: open it and it works. And if you lose signal, the day's prices are still there. Price alerts, your own colour scale and the colour widgets (today's curve, cheap hours and Lock Screen) are unlocked with a one-off in-app purchase.
