Negative electricity prices in Spain: what they mean and why you won't get paid

Negative electricity prices: the fine print nobody tells you about

At midday, between three and four in the afternoon, the price of electricity on the Spanish wholesale market fell to €3.21 per megawatt hour. Practically given away. But no, you won't get money back for using power. The auction price of the daily market is only part of what you pay: on top come grid access charges, system charges, the special electricity tax and VAT. Even if the pool goes negative for an hour, the energy term on your bill never drops below zero.

A negative price is not what it seems

Negative prices do exist in the Spanish market and there are more of them every year, but it helps to know what they actually miccionan. It is not that they pay you to take away their overproduction; it is that for certain types of generation it is still worth producing even at a negative price, thanks to mechanisms such as RECORE, the specific remuneration scheme under Royal Decree 413/2014. This system pays an operating payment for every megawatt hour generated, regardless of the price at which it is sold. So even when the auction price is negative, the installation keeps earning money.

PVPC: rip-off or useful tool?

The regulated PVPC tariff (Spain's government-set electricity rate) has defenders and detractors. Critics point to frequent spikes of 200 to 250 euros per megawatt hour, which they consider a scandal. Supporters argue that it allows you to schedule consumption and that, in terms of real cost, few offers on the free market beat it. The key is to adjust your contracted capacity and calculate the real cost by dividing the total bill amount by the kilowatt hours consumed.

Free-market offers: the fine print

An offer of €0.10 per kilowatt hour with no time-of-use discrimination looks attractive, but the price per kWh is only half the bill. Before signing, check the contracted capacity in both peak and off-peak periods. In addition, some providers offer telecom discounts if you sign up for electricity with them, which can make up the difference.

The role of RECORE

RECORE is a specific remuneration scheme for renewables, cogeneration and waste-to-energy. Facilities covered by it receive two payments: one for investment and one for operation. The latter is paid per unit of energy generated, not by the price at which it is sold. That is why, even when the market is negative, it can still pay to release energy.

So, when you see that the price of electricity is negative, remember: it is not that they pay you to consume, it is that the system is designed so that generation keeps running at any price. And you, meanwhile, can take advantage of those hours to run the washing machine, but don't expect extra income.
