Today's essentials

8 million Spanish homes saw power prices drop below zero. For the first time ever, the regulated PVPC electricity tariff that covers around eight million Spanish homes turned negative for several hours this past weekend, meaning those households were effectively paid a few cents to draw power at midday, according to Red Eléctrica figures relayed by Diario de Mallorca and Diario de Ibiza.

Both Diario de Mallorca and Diario de Ibiza, sister titles in the Prensa Ibérica group, reported the milestone using data from Red Eléctrica's ESIOS system. On Saturday 5 September 2026 the wholesale price sat between -4 and -10 euros per megawatt-hour from midday to 4pm. On Sunday 6 September the negative stretch lasted about five hours, easing from around -8.57 euros per MWh near 10am to -1.52 euros near 3pm.

The trigger was a flood of midday solar generation. When panels pour into the grid around noon, wholesale prices collapse, and this year that matters to ordinary bills: a 2024 reform means the regulated tariff now passes those swings on to customers, blending the daily market with longer forward contracts (a weighting cited at roughly 55 percent forward markets and 45 percent daily price).

Only homes on the PVPC (Precio Voluntario para el Pequeño Consumidor), the regulated tariff, felt any of it, some eight million across Spain. And before you get excited, the actual gain is tiny: for a typical home with 3 to 4 kilowatts of contracted power, analysts quoted by the outlets put the maximum benefit at about 40 cents for a single negative hour.

The real lesson is about timing, not windfalls. If you are on the PVPC tariff, running your heaviest appliances (washing machine, dishwasher, dryer, electric water heater) in the middle of the day, when solar is strongest and prices are at their lowest, is where the genuine savings sit. If you are on a fixed-rate deal with a private supplier, none of this reaches your bill at all.

What it means for you: check which tariff you are actually on. Negative prices are still rare and short-lived, but cheap midday solar power is now a regular pattern, not a fluke, and shifting your energy-hungry chores to the middle of the day is the one simple habit that turns these headlines into a slightly smaller bill.

Weather today

A hot, overcast Monday across the islands. The Balearics get a hot but grey Monday 7 September 2026, with highs of 34 degrees in Palma, 35 degrees inland around Soller and 31 degrees on Menorca, and no rain expected, according to Open-Meteo.

In Palma, temperatures run from a warm low of 24 degrees to a high of 34, under fully overcast skies with a light breeze topping out near 12 km/h and no rain on the radar. The rest of Mallorca is hotter still: Soller climbs to 35 degrees from a mild 26 overnight, with barely any wind (up to 9 km/h).

Over on Menorca, Ciutadella stays a touch cooler, between 23 and 31 degrees under the same grey cover and a gentle 12 km/h wind. With maximums at or above 34 degrees, keep water on you, stick to the shade in the early afternoon, and save any real effort for the morning or after sunset.

What's changing for you

• Menú del día: the newcomer's cheat code for lunch. A new arrival in Palma asked on Reddit's r/mallorca where to find a good-value menú del día, and the honest answer is that the format itself is the trick to eating well without overpaying. The menú del día is a weekday, fixed-price lunch that most Spanish restaurants serve: a starter, a main, bread, a drink and usually dessert or coffee for one flat price, typically cheaper than ordering the same dishes à la carte. It is generally offered at midday on working days, and often available to take away too. So if you have just moved to Palma, ask for 'el menú' at lunchtime rather than chasing a single perfect address, and you will eat properly for a fair price almost anywhere.
• 200 million euros of tourist-tax money heads to local projects. The Balearic Govern will spend 199.8 million euros of sustainable tourism tax revenue on 65 projects across the islands, focused on the water cycle, the environment, heritage and cracking down on illegal tourist rentals, according to Diario de Mallorca. This is where the sustainable tourism tax, the few euros a night you or your visitors pay at hotels, flows back into everyday island life: water infrastructure, environmental protection, heritage sites, and enforcement against illegal holiday lets that squeeze the housing market. There is nothing to sign up for, but it flags where public investment is heading over the coming year if you follow local water, housing or conservation issues.
