Electricity Prices in Spain Are Rising Again: Why Locking In Now Could Save You Money

Why are electricity prices rising again in Spain?

The immediate cause is renewed pressure in global energy markets after the escalation in the Iran conflict. Consumer group OCU says the impact is already being felt in Spain, noting that after several days below €30/MWh, the daily electricity price jumped to around €90/MWh on 5 March, with peaks of €186/MWh. OCU warns that if this level is sustained and the monthly average stays around €100/MWh, the average electricity bill could rise from around €63 in February to about €82 in March for customers exposed to indexed pricing.

That is the important detail. The people who tend to feel this first are those on indexed tariffs, including PVPC-style exposure and other market-linked contracts. Fixed tariffs do not make the market problem disappear, but they do give you shelter for a period while suppliers carry the risk instead. OCU explicitly recommends reviewing contracts, comparing offers, and anticipating possible supplier price revisions.

What are suppliers in Spain doing right now?

They look to be doing what suppliers always do when markets turn jumpy. They move into risk control.

That usually means:

• higher prices for fixed tariffs
• less enthusiasm for indexed tariffs
• more selective online offers
• faster repricing when wholesale costs move sharply

This is not panic. It is old-fashioned protection of margin and exposure. Suppliers do not like selling open-ended or lightly hedged products when gas and electricity are moving fast. The moment uncertainty returns, the generous deals start disappearing.

Is Spain heading into another full energy crisis?

Not necessarily.

Spain is better protected than it was during the worst of the 2022 shock. The government changed the PVPC methodology so that in 2026, 55% of the tariff reference comes from futures markets and 45% from the wholesale market. The point of that reform was to reduce volatility and stop bills from swinging so violently with daily wholesale prices.

So Spain is not as exposed as before. But better protected does not mean immune.

If gas remains high and wholesale electricity keeps rising, suppliers will continue to reprice fixed offers upward. In other words, the price you can lock in today may look decent in hindsight if the market worsens over the next few weeks.

Why locking in now could save money

This is the key point for households. When markets are rising, waiting can cost you in two different ways.

First, the tariff you wanted may simply become more expensive. That appears to have already happened with Octopus Relax, moving from around 12.2 cents/kWh to 14.2 cents/kWh in a matter of days.

Second, the best market-linked or lightly priced offers can become harder to access, less promoted, or removed from the most visible signup routes while suppliers reassess risk.

So if the market gets worse, people who fixed earlier could end up protected while everyone else is left comparing a smaller set of more expensive offers.

That does not mean every household should blindly lock in the first fixed tariff they see. Some solar homes, low-usage homes, or people with very specific consumption patterns may still do better on another structure. But for many households, especially those who value certainty, the logic is straightforward: when suppliers are repricing up, yesterday's fixed tariff is often better than tomorrow's.

What should households in Spain do now?

Right now, the smart move is not just to chase the lowest headline kWh price.

You need to check:

• whether your tariff is fixed or indexed
• how long your current rate is protected for
• what you are paying for contracted power
• whether your usage pattern actually suits the tariff you are on

A tariff that looks cheap in calm conditions can become poor value very quickly when markets turn. That is why proper comparison matters more now than it did a month ago.

Our view

The Spanish energy market in early March 2026 feels cautious and defensive. Wholesale prices have turned higher, suppliers are reacting, and the easy pricing environment has clearly worsened. Spain is in a better position than during the last major energy shock, but households should not assume this will simply blow over with no effect on retail tariffs.

The plain truth is this: if prices keep rising, locking into a sensible fixed tariff now could save money compared with waiting another week or two.
