Utility Bill Decree (Law 49/2026): EU Blocks ETS Mechanism
Excerpt
Italy’s new energy decree—the Decreto Bollette—is the most significant regulatory intervention in the European electricity market in years. It lowers wholesale prices by subsidizing the marginal costs of fossil fuels, causes solar capture prices to plummet, and brings the PPA market to a standstill. For PV investors with exposure to Europe, this marks a turning point—and serves as a lesson in just how crucial regulatory stability is for long-term returns.
Update May 5, 2026: With the EU’s blocking of the ETS amendment on April 29, 2026, the worst-case-scenario revenue shortfall for Italian solar investors has been averted—but the damage to regulatory confidence remains.
-
The Decreto Bollette has been in force since April 19, 2026 , as Law No. 49 of April 10, 2026 (Official Gazette No. 90/2026). The €5 billion package was intended to reimburse gas-fired power plants for their ETS and transportation costs, thereby lowering wholesale prices. However, on April 29, 2026, the European Commission indirectly blocked the ETS modification —via the MeTSAF communication on the state aid framework. This effectively nullifies the core of the decree: the ETS reimbursement cannot take effect without EU approval. The gas transport mechanism (-€6.3/MWh PUN) remains in place, as does the Conto Energia reduction. For PV investors: The original worst-case scenario (-30% capture price) has been averted, but regulatory uncertainty remains. For companies looking to install their own PV system, we recommend taking a look at the Logic Energy’s self-consumption model.

What is the Decreto Bollette?
The Decreto Bollette began as an Italian emergency decree (DL 21/2026 of February 20, 2026) and has been in force since April 19, 2026, as Law No. 49 of April 10, 2026— published in the Official Gazette No. 90 of April 18, 2026. The conversion law was passed by a vote of confidence on March 31, 2026, in the Chamber of Deputies (203–117) and on April 8, 2026, in the Senate (102–64). The consolidated text of the law (Decree-Law + conversion) was published simultaneously in the same Official Gazette.
The official title is: “Misure urgenti per la riduzione del costo dell'energia elettrica e del gas” – Emergency measures to reduce electricity and gas costs for households and businesses (famiglie e imprese). The Council of Ministers of the Meloni government approved the package on February 18–19; the Gazzetta Ufficiale published it on February 20, and it entered into force on February 21. The official date of issuance, cited as authoritative in international sources (including DLA Piper), is February 24, 2026. Since the decree took effect immediately and acquired the force of law following parliamentary confirmation, all measures contained therein are directly binding—an important clarification compared to merely announced regulatory proposals. Following a voto di fiducia —a vote of confidence—in the Chamber of Deputies (March 31, 203 to 117 votes) and in the Senate (April 8, 102 to 64), it was finally confirmed as a legge (law) on April 8, 2026.
The political context: Italy has some of the highest electricity prices in Europe. According to Confcommercio, system charges—particularly the ASOS component used to finance renewable energy incentives—account for over 20% of commercial electricity bills. Prime Minister Meloni described the package as a “structural, not emergency-driven” measure. The total volume exceeds 5 billion euros. During the parliamentary conversion process, numerous amendments were introduced—including a ban on telemarketing, a 2% increase in IRAP for energy companies, and regulations on virtual grid saturation—which have significantly expanded the scope of the decree.
Overview of Goals and Impact
The official main objective of the decree is to provide financial relief to end consumers—households (famiglie) and businesses (imprese)—through direct reductions in electricity and gas costs. For consumers, the law includes, among other things, social bonuses and a reduction in the electricity tax. For PV investors, the other side of this equation is crucial: the relief provided to gas-fired power plants comes at the expense of renewable energy revenues. The decree does not lower the costs of generation—it shifts them. Anyone wishing to assess the significance of the Decreto Bollette for their portfolio must understand both sides of this equation.
The Six Core Mechanisms of DL 21/2026
The Bollette Decree includes six measures that directly affect the electricity market: reimbursement of gas transmission tariffs, reimbursement of ETS costs to gas-fired power plants, a voluntary reduction in historical Conto Energia payments, and a temporary reduction in the electricity tax. Together, these measures could lower the wholesale electricity price (PUN) by up to €26/MWh—at the expense of renewables.
Reimbursement of gas transmission tariffs (Art. 6, para. 2)
Starting January 1, 2027, ARERA will reimburse gas-fired power plant operators for variable gas transmission tariffs and certain system charges. The costs will be passed on to electricity consumers via new tariff components. ICIS analyst Luca Urbanucci estimates the effect at a reduction of approximately €6.3/MWh in the average PUN. Important: This measure is not explicitly linked to EU approval in the text of the decree—which raises questions under EU state aid law.
ETS Reimbursement (Art. 6, para. 3)
Gas-fired power plants are to receive a reimbursement equivalent to the expected EU ETS costs of an efficient combined cycle gas turbine (CCGT) plant. With CO₂ prices of around €70 per ton, this translates to a reduction of approximately €25–30 per MWh. This mechanism is expressly subject to prior approval by the European Commission under Article 108(3) TFEU. Together with the gas transmission reimbursement , this results in a total effect of up to €26.1/MWh on the PUN—provided the Commission approves it.
Conto Energia cuts (Art. 2)
Operators of PV systems with a capacity of over 20 kW—including both rooftop and ground-mounted systems—who receive feed-in tariffs under the first through fourth Conto Energia programs and whose contracts expire on or after January 1, 2029, may voluntarily choose between the following options by May 31, 2026:
Option A: 15% rate reduction (July 2026 – December 2027) in exchange for a 3-month contract extension
Option B: 30% reduction in exchange for a 6-month extension
Exit option starting in 2028: Compensation payment of approximately 90% of the present value of the remaining cash flows (spread over 10 years) in exchange for full repowering with a doubling of capacity – limited to a maximum cumulative total of 10 GW
Affected: approximately 52,400 facilities with a total capacity of 13.3 GW.
Temporary reduction in the electricity tax (Art. 1)
In addition, the decree temporarily reduces the electricity tax for businesses to the EU-mandated minimum of €0.50/MWh. This measure is directly aimed at providing relief to businesses (imprese) and is intended to improve the competitiveness of energy-intensive industries. It is indirectly relevant for PV investors: If the tax component in the electricity bill decreases, the comparative cost advantage of self-generated solar power over grid-purchased electricity is reduced—which affects the profitability calculations for self-consumption projects.
⚠️ Note: The percentages and time periods mentioned here are based on the legal situation in effect at the time of publication. ARERA implementing regulations may still modify the specific implementation. As of May 2026.
Direct electricity bill contributions for all businesses (Art. 1)
The Conversion Act specifies the direct contributions: 431 million euros for 2026, 500 million for 2027, and 68 million for 2028. Translated into reductions per MWh: -3.4 €/MWh (2026), -4 €/MWh (2027), -0.54 €/MWh (2028). These amounts go to all companies regardless of size or consumption threshold. They are financed through a +2% increase in the IRAP tax on energy companies (electricity production, transmission, distribution, gas, and petroleum products) for 2026 and 2027—an internal redistribution within the energy sector.
Prohibition on Telemarketing (Art. 1, para. 5-bis, newly introduced by the Camera Amendment)
The Chamber of Deputies has introduced a general ban on cold-calling practices in the electricity and gas sales sector. As of June 19, 2026 (60 days after the law takes effect), telephone calls and text messages used to initiate contracts will be null and void unless the consumer has actively requested such contact. AGCOM may block suspicious telephone lines, and the Data Protection Authority will oversee compliance. Contracts concluded through prohibited telemarketing will be declared null and void. For PV investors, this point is indirectly relevant: It demonstrates how the conversion process has expanded the decree to include consumer policy provisions—with specific compliance requirements for each electricity provider.
The following section illustrates how these six mechanisms have specifically affected the revenues of solar power plants and the stock prices of major utilities.
Impact on solar capture prices and merchant plants
When gas-fired power plants are reimbursed for their marginal costs, the number of hours during which solar power sets the market price decreases—and with it, the revenues of all merchant plants. ICIS forecasts a decline in the capture price of over 30% for unsecured solar plants in Italy.
Immediate impact on the market
The analysis firm ICIS identifies several levels of impact:
Immediate impact (without EU approval): The elimination of the gas spread and the reduction in transmission tariffs are pushing down the PUN by approximately €4–7/MWh
Full impact (with EU approval): price reduction of up to €25–30/MWh for renewable energy producers (Equita SIM, Intermonte)
Decline in capture prices: over 30% for unsecured solar power plants (ICIS, February 2026)
Reaction from the utilities
The market reaction has unfolded in two stages since February 2026—following the entry into force of the DL and following the EU’s veto. Current situation:
Italian Year-Ahead Power: Initially fell by nearly 15% after the DL took effect (Bloomberg, February 18, 2026). The Iran-Hormuz conflict since March 2026 has been driving prices back up.
PUN Spot: Stood at around €113.61/MWh on May 4, 2026 (GME data, monthly average) — higher than before the decree.
ENEL stock: After falling 4.19% over the first four days, the stock rebounded to a two-year high of €10.33 on Capital Markets Day (February 23, 2026). It is currently (May 2026) trading at around €9.50–€9.70.
A2A, Iren, Hera: A profit impact of -1.5% to -2% is expected due to the IRAP increase.
Terna, Snam, Italgas: Estimated earnings impact of -3% to -4% (FIRSTonline, March 2026).
Risk to investors
The law firm DLA Piper identifies the merchant sector as a "major area of concern": projects without long-term hedging could see a significant decline in expected revenues. The impact is unevenly distributed:
Pure merchant plants (no PPA, no FER-X): immediate erosion of revenue
Assets already financed: gradual decline, depending on the refinancing structure
Development projects in the pipeline: potential financing barriers as bankable cash flows decline
Added to this is a regulatory risk factor: Agostino Re Rebaudengo, Vice President of Finco, put it this way: “In the financial markets, such interventions (interventi) are not viewed as isolated incidents, but as precedents that redefine the overall reliability of the regulatory framework.” Consequently, the decisive factors for assessing returns no longer include only technical metrics, but increasingly the political stability of the investment location—because declining proventi (revenues) cannot be offset by better modules.
Another risk to the decree’s logic itself: Geopolitical tensions could quickly drive gas prices back up, thereby undermining the decree’s underlying assumptions. ECCO Climate pointed out that just one week after the law took effect, a new geopolitical event—rising gas prices resulting from geopolitical escalation—already began to undermine the Governo’s underlying assumptions. This demonstrates that a decree based on low gas prices is structurally fragile.
⚠️ Third-party yield estimates (ICIS, Equita SIM, Intermonte) are based on model calculations as of the date of publication. Actual market performance may differ.
In addition to capture prices coming under pressure, PPA contracts and the revenue model for battery storage are also facing challenges—as Section 4 explains in detail.
The PPA Market and Battery Storage: What's Actually Changing
Falling wholesale prices driven by government subsidies for the marginal costs of fossil fuels are simultaneously eroding the value of PPAs and storage arbitrage. ICIS expects a "sharp slowdown" in the PPA market and a decline in the day-ahead spread of around 10% by 2027.
PPA Market Under Pressure
Solar PPAs in Italy are based on spot prices. If spot prices fall, so do the fair value prices for new contracts. According to Pexapark, the solar PPA fair value for 10-year contracts in Italy stood at €58–59/MWh (as of March 2026)—a figure that will recalibrate in the medium term as the PUN declines.
Two critical legal issues arise with regard to existing PPAs:
Change-in-law clauses: Do they apply when government intervention alters the revenue base? That depends on the specific terms of the contract.
Double burden: Customers with fixed-price PPAs have already factored ETS costs into their pricing. New system fees to finance ETS reimbursements could place an additional burden on them—which would complicate PPA negotiations.
DLA Piper cites Article 1467 of the Italian Civil Code (excessive burden due to unforeseen circumstances) as a possible legal remedy for affected parties.
Battery Storage: Arbitrage Erosion in Detail
ICIS forecasts a contraction in average intraday spreads in the day-ahead market of around 10% by 2027. The mechanism: With CO₂ prices at €70 per ton, the ETS component accounts for 20–30% of a gas-fired power plant’s spot market bid (Modo Energy, KEY Expo March 2026). The removal of these costs compresses peak prices more than off-peak prices—and narrows precisely the spread on which battery storage relies.
The seasonal effect is clear: the measure has the greatest impact during the summer, when solar power drives midday prices and only the evening peaks are dominated by gas. Batteries designed to generate revenue from peak shaving thus lose revenue potential during their most valuable operating hours.
⚠️ ICIS projections are based on market models as of February/March 2026 and are subject to change based on ARERA implementation regulations and EU decisions.
EU State Aid Review: Why Approval Is Uncertain
The ETS refund for gas-fired power plants requires approval from the European Commission—and this is a significant hurdle. No EU member state has ever received such approval for direct ETS costs for electricity producers. Legal experts consider approval in its current form to be unlikely.
Four legal hurdles, according to ADVANT Nctm
After conducting an 11-point analysis, the law firm ADVANT Nctm has reached a clear conclusion:
No precedent: All ETS offset schemes approved to date (Germany SA.36103, Poland SA.53850, UK SA.35543) relate to indirect ETS costs incurred by electricity-intensive consumers —not generators
Violation of the polluter-pays principle: The decree provides relief to those who emit CO₂ without requiring anything in return
No environmental requirements: Approved schemes require compliance with ISO 50001, energy efficiency measures, and decarbonization investments (≥50% of the aid amount)—the decree contains none of these provisions
SDAC/CACM Conflict: The measure interferes with EU market coupling rules
ICIS analyst Urbanucci puts it bluntly: “Approval of the proposal for ETS cost reimbursement in its current form seems unlikely under state aid rules.” ECCO Climate describes the key measure as “in explicit contradiction to European regulations and single market rules.”
Timeline: 20 business days for preliminary review, up to 18 months for the proceedings
Important for timing: Under Article 108(3) of the TFEU, the European Commission must first decide within 20 working days of receiving the notification whether to open a formal investigation. The formal procedure itself can then take 12–18 months. For investors, this means: Even in the best-case scenario of a swift preliminary review, there will still be 1–2 years of regulatory uncertainty—a period during which financing for new projects in Italy will be virtually impossible to secure.
The ARERA suspension decision of March 30, 2026, was issued before Law 49/2026 came into effect; ARERA has since published subsequent resolutions implementing the conversion law (including 81/2026/R/eel). Approximately 500 million euros in planned relief measures are thus frozen. Separately, the decree contains rules on virtual grid saturation (saturazione virtuale delle reti) and on the connection of data centers (centri di calcolo) to the electricity system —technical interventions that accelerate grid expansion but may simultaneously create new burdens for renewable energy providers.
Three investment scenarios
For investors, this results in an asymmetric risk:
Scenario 1 (Approval): Structural restructuring of the merit order at the expense of renewables; PUN declines permanently
Scenario 2 (Rejection): Reversal of the transaction; regulatory breach of trust remains nonetheless
Scenario 3 (Redesign): Partial solution with a modified mechanism – uncertainty remains until a decision is made
Modo Energy sums it up: “Until a decision is made, the uncertainty alone is enough to slow down investment.”
This analysis was conducted prior to the EU decision. The following section describes what the Commission actually decided.
Update April 29, 2026: EU Commission blocks ETS mechanism
On April 29, 2026, the European Commission indirectly blocked the ETS amendment to Law 49/2026. In its MeTSAF communication on the state aid framework for the Mediterranean and Hormuz crises, Brussels made it clear: The passing on of ETS costs from gas-fired power plants to consumers is incompatible with EU state aid law and the ETS system. This effectively nullifies the core provision of the decree—thus sparing Italian solar investors from significant market distortion.
How the blockade came about
The Commission did not intervene through a separate state aid procedure, but took a different approach: On April 29, 2026, it published the MeTSAF Communication (Mediterranean & Strait of Hormuz Aid Framework)—the temporary state aid framework for sectors particularly affected by the Hormuz crisis. Embedded within it was a clarification that the Italian ETS modification did not fall within the scope of the approved measures. This was the diplomatic way to avoid a formal procedure under Article 108(3) TFEU—while simultaneously signaling to Italy that a direct notification would have no prospect of success.
The Commission’s reasoning is straightforward: ETS rebates to electricity generators weaken the ETS system as a whole, as they shift CO₂ costs from emitters to end consumers. In doing so, they violate the polluter-pays principle and the principle enshrined in Article 191 of the TFEU. This is precisely the line of reasoning that ADVANT Nctm had already predicted in its 11-point analysis from March 2026.
What remains of the decree—and what does not
Law 49/2026 includes three mechanisms for intervening in the electricity market. Only one of them has been blocked by the EU.
| Mechanism | Validity | Effect on PUN | Status following the EU decision |
|---|---|---|---|
| ETS Rebate for Gas-Fired Power Plants | Article 6, paragraph 3 | from −25 to −30 €/MWh | Blocked not in effect |
| Gas Transportation Reimbursement | Article 6, paragraph 2 | −6.3 €/MWh | Stay active Not subject to EU approval |
| ASOS Sale via ARIM-Tempi | Art. 6, additional | −6.8 €/MWh (~850 million €) | Stay active |
| Conto Energia Cut | Article 2 | Optional election until May 31, 2026 | Stay active |
| Direct contributions to electricity bills | for all businesses | −3.4 €/MWh (2026) | Stay active |
| Reduction in the Electricity Tax for Industry | EU minimum rate | €0.50/MWh | Stay active |
| Sources: Official Gazette No. 90/2026 (Law 49/2026) · Euronews April 29, 2026 (EU ETS blockade via MeTSAF communication) · ICIS February 2026 (PUN effect estimates) · Confcooperative April 2026 (direct contributions). As of May 5, 2026. | |||
The result: Instead of the projected €26/MWh drop in the PUN, only a reduction of approximately €13/MWh from the non-blocked mechanisms is now plausible. The original ICIS warning of a capture price decline exceeding 30% for merchant solar thus loses its upper limit. At the same time, the Iran/Hormuz conflict is driving wholesale prices even higher— on May 4, 2026, the PUN stood at around €113.61/MWh (GME data via abbassalebollette.it), well above the February low.
What Italy could do now
There are three options on the table:
Tacit waiver. The ETS refund is effectively not implemented; the decree proceeds with the remaining provisions. This is politically unappealing, as it eliminates the main selling point for voters.
Modification and re-notification. The subsidy will be restructured, for example as earmarked investment support for gas-fired power plants subject to decarbonization requirements—modelled on the approved ETS compensation schemes for electricity-intensive consumers (Germany SA.36103, Poland SA.53850).
Dispute resolution procedures. Italy could file a lawsuit with the European Court of Justice or request a formal decision from the Commission in order to escalate the dispute politically. This is unlikely, as the process takes 2–3 years and the decree would have lost its political relevance by then.
ECCO Climate had already warned in March that the decree was “in direct conflict with European regulations.” The EU’s response on April 29, 2026, confirms this assessment.
What this means in practice for PV investors
Three implications for the investment decision:
Capture price risk is decreasing. The ICIS worst-case forecast (a decline of more than 30%) is no longer a concern. The PUN decline resulting from the remaining mechanisms is around €13/MWh—significantly smaller than the politically planned reduction.
Confidence in regulation remains shaken. Even though the worst-case scenario was averted, the Italian government pushed through a mechanism in Parliament that was vulnerable to legal challenges under EU law from the very beginning. This sets a precedent that institutional investors will factor into future risk premiums.
The deadline for the Conto Energia option (May 31, 2026) remains in effect. Operators of existing plants must decide on the voluntary tariff reduction by the end of May 2026—this mechanism is not subject to EU review and is therefore active. Those who choose the 85% option accept a 15% reduction in exchange for a 3-month extension; with the 70% option, it is 30% in exchange for 6 months.
As Agostino Re Rebaudengo (Vice President of Finco) noted back in February: Such interventions are not viewed by the financial markets as isolated incidents, but as precedents that redefine the overall reliability of the regulatory framework. The EU blockade alleviates the immediate revenue crisis—but the longer-term question of confidence remains.
⚠️ As of May 5, 2026: Although the EU communication has been published, the Italian legislature has not yet publicly decided how to address the blocked mechanism. ARERA is expected to take follow-up action in the coming weeks.
The European BESS Market and a Comparison with Germany
While Italy is imposing regulatory burdens on its solar sector, the European energy storage market is growing at a record pace—and Germany is demonstrating how predictability attracts investment. 27.1 GWh of new battery storage capacity in the EU by 2025, 117 GW of cumulative solar capacity in Germany, and a fundamental reform of grid connection rules provide a stark contrast.
European BESS Market 2025: Key Figures
According to SolarPower Europe (January 28, 2026), a total of 27.1 GWh of new battery storage capacity was installed in the EU in 2025:
Year-over-year growth: +45% (from 18.7 GWh to 27.1 GWh)
Total EU capacity: 77.3 GWh (a tenfold increase since 2021)
Utility-scale projects take the lead for the first time: 15 GWh (55% of new installations)
Top 5 markets: Germany (6.6 GWh), Italy (4.9 GWh), Bulgaria (2.5 GWh, +1,100%), the Netherlands (1.7 GWh), Spain (1.4 GWh)
Over 80 GWh awarded through auctions
⚠️ Market data is based on SolarPower Europe figures as of January 2026. Final annual figures may vary slightly.
Germany: Stable regulatory environment, strong results
In 2025, Germany added approximately 16.4 GW of new solar capacity (Federal Network Agency; BSW-Solar puts the figure at ~17.5 GW, including late registrations). Cumulative capacity thus reached approximately 117 GW —55% of the 215-GW target for 2030.
Additional key figures:
Solar power generation in 2025: approx. 87 TWh (+21% compared to the previous year)
Share of the electricity mix: higher than lignite for the first time (Fraunhofer ISE, January 2026)
Record day, June 20, 2025: 50.4 GW of solar capacity = 98.6% of the load
Large-scale storage in 2025: from 2.3 GWh to 3.7 GWh (+60%, Fraunhofer ISE)
⚠️ All expansion and generation data are preliminary (Federal Network Agency / Fraunhofer ISE, as of January 2026) and are subject to change based on subsequent reports.
The KraftNAV reform simultaneously reduces the burden on the German grid connection
"In parallel with the regulatory debate in Italy, Germany is reforming grid connection for large-scale storage facilities with the KraftNAV amendment of December 2025—moving away from the first-come, first-served principle toward a maturity-based approach. The contrast is clear: while Italy is debating retroactive changes to existing revenue structures, Germany is establishing clear new framework conditions."
Three takeaways for PV investors
The Bollette Decree demonstrates that regulatory predictability is not a minor factor, but rather one that can make or break returns. Three concrete takeaways for PV investors with exposure to Europe.
Reassessing Merchant Risks in Italy
Pure merchant positions in Italy must now be calculated with an increased regulatory premium. The relevant question is not “Will the decree be implemented?” but “How high is the uncertainty premium that a rational investor demands for this uncertainty?” Projects with long-term revenue hedging via government-guaranteed contracts for difference are structurally privileged. Specific auction prices and mechanics can be found in the complete market analysis: PV Investment Italy 2026.
Review PPA contract clauses for changes in the law
Investors and project developers shouldreview existingPPAs to address the following questions: Does the contract include change-in-law clauses? Are ETS costs explicitly factored into the price? Are there adjustment rights in the event of government intervention in the merit order? This analysis is particularly relevant for assets with remaining terms of less than 10 years that do not have a government-backed difference contract.
PV + Storage as the Standard for Co-location
The "Decreto Bollette" debate underscores a trend that has long been evident in market structures: Standalone power generation facilities without storage components are increasingly losing value in saturated markets. Co-location is thus evolving from an upgrade to a fundamental building block—both in Italy and in Germany. An integrated PV-BESS approach secures multiple revenue streams— direct marketing, balancing energy, arbitrage—and reduces dependence on a single price signal source. Especially in a market like Germany, where the CfD requirement starting in 2027 will impose new demands on the revenue structure, co-location capability is not an upgrade but a fundamental building block. Providers who deliver comprehensive solutions from a single source—from planning and construction to operations management—have a clear advantage in this environment.
The Decreto Bollette is just one component of Italy’s regulatory framework. The comprehensive market analysis, *PV Investment Italy 2026*, places FER-X auctions, the TIDE reform, the MACSE storage program, and agri-PV within the broader context.

The Decreto Bollette is a wake-up call: Anyone investing in photovoltaics is not just investing in hours of sunshine and module prices—they are investing in the regulatory framework. Italy’s energy policy shows how quickly a stable market can collapse. Germany currently offers the more reliable environment—with predictable EEG feed-in tariffs, a growing large-scale storage market, and clear grid connection rules.

FAQ
-
The Decreto Bollette has been in effect since April 19, 2026 , as Law No. 49 of April 10, 2026, following the conversion of the original Decree-Law 21/2026 of February 20, 2026. The €5 billion package reimburses gas-fired power plants for gas transportation costs and was intended to reimburse ETS costs—the latter was blocked on April 29, 2026, by the European Commission via the MeTSAF Communication.
-
Following the EU’s blocking of the ETS modification, a worst-case decline of over 30% is no longer realistic. The remaining PUN decline from gas transport and ASOS reduction is around €13/MWh instead of the originally planned €26/MWh. These figures are market analysis forecasts (ICIS, Equita SIM) and do not guarantee actual price trends.
-
Yes. On April 29, 2026, the European Commission indirectly blocked the ETS modification—through the MeTSAF communication on the state aid framework. This confirmed ADVANT Nctm’s prediction: No EU member state has ever received approval for direct ETS costs for electricity producers. The ETS reimbursement will not take effect without EU approval.
-
This affects PV systems with a capacity of over 20 kW that are subsidized under the first through fourth Conto Energia programs and whose contracts do not expire until January 1, 2029. Approximately 52,400 systems with a total capacity of 13.3 GW can voluntarily choose between a 15% or 30% tariff reduction by May 31, 2026.
-
ICIS expects day-ahead spreads to contract by about 10% by 2027. The mechanism: Subsidized marginal costs for gas-fired power plants are squeezing peak prices more than off-peak prices, thereby narrowing the arbitrage margin for batteries. The effect is most pronounced in the summer.
-
The Chamber of Deputies included, among other things, a ban on telemarketing (effective June 19, 2026), a 2% increase in the IRAP tax for energy companies (2026/2027), and regulations on virtual grid saturation and the integration of data centers. The original €60 bonus for ISEE up to €25,000 was eliminated—instead, energy providers will make a voluntary contribution with no fixed amount. The Conto Energia mechanism was confirmed: the deadline for choosing between the 85% or 70% option is May 31, 2026.
-
By 2025, Germany will have installed approximately 117 GW of cumulative solar capacity, expanded large-scale storage by 60%, and established clear guidelines for grid connections through the KraftNAV reform and the new maturity assessment procedure. The regulatory environment is more stable and predictable than in Italy—a decisive factor for institutional investors.
-
Three measures: (1) Factor in a higher regulatory premium when calculating merchant positions; (2) Review existing PPAs for change-in-law clauses; (3) Focus on projects with long-term revenue hedging (FER-X, MACSE, PV+BESS co-location). Pure merchant positions without hedging are structurally disadvantaged in an environment of regulatory uncertainty.
-
The decree includes direct relief for consumers: a reduction in the electricity tax to the EU minimum, social rebates for low-income households, and structural relief for businesses through reduced grid fee components. The official goal is to lower electricity and gas bills. For PV investors, however, the flip side is crucial: This relief is financed by falling wholesale prices, which directly reduces the revenue from solar installations.
