European energy M&A remains resilient as investors focus on grid infrastructure, renewables platforms and policy-backed transition assets
M&A activity in the European energy sector moderated in 2025 but remained resilient, with total deal value reaching approximately €57.5 billion across 893 transactions. Although this marks a decline from the elevated levels recorded in 2024, the market demonstrated depth and stability, supported by sustained investor interest in grid infrastructure, power platforms and selected conventional energy assets.
Despite a more cautious macroeconomic backdrop – characterised by geopolitical volatility, higher financing costs and evolving regulatory frameworks – deal flow remained healthy, especially in core infrastructure segments. Rather than experiencing a sharp correction or surge, the market consolidated around policy-driven investment themes, with capital gravitating towards system-critical assets and mature platforms offering long-term revenue visibility.
Germany reaffirmed its role as Europe's most active M&A market, accounting for approximately €23.2 billion in deal value – around 40% of total European energy M&A. This reflected continued momentum in grid infrastructure, renewable energy and energy storage assets, alongside platform-scale consolidation in both regulated and merchant energy businesses. Spain followed with €7.5 billion in deal value across 98 transactions, driven largely by solar PV, hybrid and battery storage projects. Italy and France recorded comparable levels of activity, with €5.9 billion and €5.6 billion in deals respectively, while the Netherlands saw €2.6 billion in energy M&A. Combined, these five markets represented more than two-thirds of European deal value, with investors focusing on markets offering size, liquidity and regulatory support.
Sectors with strong performance
Power and grid infrastructure led the market in 2025, accounting for nearly 60% of total energy deal value. Investor appetite remained concentrated in electricity transmission and energy services, reflecting the structural shift toward electrification and system flexibility. Standout transactions included the €9.5 billion acquisition of a 46% stake in German TSO TenneT by a consortium of state-backed investors (APG, GIC and Norges Bank), Apollo’s €3.2 billion investment in Amprion, and the €6.7 billion full acquisition of Techem GmbH by a Swiss-led investor group.
These deals reflect increasing institutional interest in regulated and semi-regulated grid assets that benefit from long-term earnings visibility. Momentum in the renewables sector, particularly solar and wind, was also evident. Ares Management’s €2 billion minority acquisition in Eni Plenitude and Velto’s €1.1 billion acquisition of two solar portfolios in Spain underscore continued investor confidence in integrated clean energy platforms. Another notable transaction in this space was Ardian’s €2.1 billion leveraged buyout of French renewables firm Akuo Energy, signalling ongoing appetite for large-scale energy transition assets.
The oil and gas sector saw continued portfolio optimisation and capital recycling, with €13 billion in total deal value across 128 transactions. Activity was shaped by strategic divestments, midstream consolidation and a selective focus on downstream assets with stable cash flows. Notable transactions included Stonepeak and Energy Equation Partners’ €1.5 billion acquisition of a controlling stake in JET Tankstellen Deutschland and Mitsui OSK Line’s €1.58 billion acquisition of Rotterdam-based LBC Terminals. Both reflect sustained investor interest in established infrastructure with long-term demand visibility.
The legal trends shaping energy M&A in Europe
The European energy M&A landscape is being driven not only by market fundamentals, but by a shift in legal and regulatory trends. As governments move from crisis-era interventions towards long-term industrial planning, a new legal-political consensus is emerging – one that prioritises system resilience, energy security and competitiveness.
The Clean Industrial Deal, launched in the beginning of 2025, crystallises the EU’s strategy to position grid infrastructure, renewables, low-carbon fuels, storage and carbon capture as industrial priorities. It also provides an overarching framework for public co-financing, permitting acceleration and policy-driven de-risking. The EU Grids Package, presented in December 2025, introduced a range of legislative measures aimed at accelerating grid modernisation and cross-border interconnection. These reforms reinforce the attractiveness of transmission and distribution assets for institutional investors, particularly in core markets, where public funding and regulatory clarity are increasingly seen as bankability catalysts.
These EU-level trends are reinforced by national initiatives, notably in Germany, where a €500 billion sovereign infrastructure fund was launched in March 2025. At least €100 billion is earmarked for energy transition priorities, including grid modernisation, energy storage, and industrial decarbonisation. The fund’s design is explicitly aimed at attracting co-investment from infrastructure funds and institutional capital. This regulatory-financial shift is transforming Germany into one of the most dynamic markets for energy infrastructure M&A.
Outlook for 2026
We expect M&A activity in the European energy sector to remain resilient in 2026. While macroeconomic uncertainty, further commodity price volatility and equipment cost inflation may weigh on some financing structures, the policy environment continues to support capital deployment in energy transition infrastructure.
Renewables, grid expansion and battery storage are expected to dominate transaction pipelines, particularly where projects are mature, cash-generative and aligned with regulatory frameworks offering stability or public co-investment. Portfolio rebalancing will also be a key driver, as some international players reassess their exposure to US renewables markets and look to deploy capital in more stable European jurisdictions. Developers are increasingly shifting from early-stage development risk to acquiring or scaling operational platforms. Private equity sponsors that entered the market five to seven years ago may also pursue exits, with strong secondary demand expected in renewables and regulated infrastructure.
With the EU targeting 200 GW of energy storage by 2030, battery energy storage and grid services will also see heightened activity, with legal structuring playing a key role in unlocking project finance and navigating grid connection and curtailment regimes.
Against this backdrop, M&A activity in 2026 is likely to coalesce around policy-aligned, system-relevant assets that offer scale, resilience and long-term revenue certainty. As industrial strategy and energy policy become increasingly intertwined, legal and regulatory positioning will remain pivotal – shaping both asset valuation and the evolving contours of deal origination across the European energy landscape.
