Spain locks in 7% generation tax removal, setting 2028 deadline
Madrid converted a temporary war-driven suspension into a confirmed phase-out, offering long-term certainty to generators expanding the country's renewables base.
Spain's government on Monday (2026-06-29) approved a gradual phase-out of the 7% levy on power generation, committing to full elimination by 2028 and removing uncertainty for an energy sector that had been operating under a temporary suspension since March.5
What had been a crisis measure is now a permanent policy commitment. The tax was suspended as energy bills climbed in the wake of the Middle East war; converting that suspension into a definitive elimination means generators can price investment decisions over a multi-year horizon without factoring in a potential reinstatement of the charge.5
The first step is a reduction from 7% to 5%, with further cuts to follow before the full elimination in 2028, Montel reported, citing the government's approved roadmap.5
Spain's power market is unusually well-placed to absorb and benefit from this kind of structural reform. Fossil-fuel plants set the wholesale price in just 15% of hours so far in 2026, according to Ember, compared with 89% in Italy over the same period.4 Wind and solar account for more than 40% of total electricity supply3, and at the end of April, renewables represented 70% of Spain's total installed capacity of 138.8 GW, according to TSO Red Electrica data.2
That market structure matters for how the tax removal flows through to prices. In a gas-dominated grid, removing a generation levy mainly reduces the cost floor for dispatchable plants that set the marginal price. In Spain, where renewable capacity keeps the marginal setter to thermal units for only a fraction of hours, the tax had been falling disproportionately on operators whose output is priced not at the margin but in bilateral contracts or capacity payments. Its removal is most valuable as a return improvement for project developers and existing wind and solar operators.4,3
The Bank of Spain estimated that the renewables buildout cut wholesale electricity prices by 40% in 2024 relative to what they would have been if the energy mix had stayed as it was in 2019.3 Monday's (2026-06-29) decision is designed to sustain that trajectory. The government framed the phase-out explicitly as a measure to cut consumer bills and boost electrification.
Capacity additions have been running at a pace consistent with those ambitions. Spain connected around 1 GW of renewable capacity in April, including 931 MW of solar and 111 MW of wind, preliminary Red Electrica data showed.2 The country ended the month with 43,214 MW of solar and 33,443 MW of wind online, with April's additions running 28% above the 783 MW connected in March.2
Green investors have been watching Madrid's policy signals closely. An EU-level windfall tax proposal sought by five member states drew sharp criticism from industry observers in May (week of 2026-05-18), with warnings that such levies risk deterring capital and distorting markets without reducing fossil fuel use.1 Spain's decision to move in the opposite direction puts it at odds with the direction some European governments are pushing.
The timing has its own complications. The 7% tax was suspended in March specifically to ease cost pressures arising from the Middle East conflict, suggesting the government had been treating the levy as a policy lever during supply shocks. Converting that suspension into a permanent removal closes off the option of reinstating it quickly in a future energy crisis, a constraint that will matter if European power markets face another period of significant supply stress.
For now, ICE Endex TTF front-month was trading at €42.11 on Monday (2026-06-29), down 0.73% on the day, while the KRBN carbon proxy was flat at €79.23. Germany's day-ahead power benchmark was up 4.30% on the session. None of those moves are directly linked to Madrid's announcement, but they frame the environment: European gas prices are moderating, giving Spain room to ease generation-side costs without the move being read as distress signaling.
The next marker is how quickly the cut to 5% takes effect and whether the legislation passes through Spain's parliament without amendment. A coalition that relied on a suspended tax to manage the political fallout of rising bills will need parliamentary support to make the phase-out permanent, and the terms of that debate will determine how reliably generators can rely on the 2028 deadline.5
