Can alternative capital solve Europe’s clean energy bottleneck?

7 July 2026

Europe is accelerating its roll-out of clean power. Yet the grids and transmission infrastructure needed to make that power usable are struggling to keep up. 

According to the European Commission, investment in the energy sector must reach approximately €660 billion annually between 2026 and 2030, more than double the €240 billion annual average between 2011 and 2021, with public funding explicitly acknowledged as insufficient to close the gap.[1] The European Investment Bank's commitment of €75 billion over three years is a fraction of what is required.[2]

The Iran war has sharpened the urgency, costing the EU at least an additional €24 billion in fossil fuel imports and prompting the Commission to launch the AccelerateEU package.[3] Draft emergency plans to cut electricity taxes and accelerate clean energy deployment are expected to be a powerful policy tailwind for energy entrepreneurs.[4]

Significant progress has been achieved. Wind power has overtaken natural gas to become Europe's second-largest source of electricity, behind nuclear, and renewables reached 48% of the EU's electricity mix in 2025, up from 36% in 2021.[5],[6] Demand is recovering too: after two decades of contraction, Goldman Sachs expects European power demand to grow 1.5-2% annually from 2026, driven by electrification of heat and transport and rising load from data centers and AI.[7] 

Europe's success in building clean energy capacity has exposed a deeper problem. There is now so much solar that power is being wasted, and negative prices during peak hours are eroding returns on projects that looked like safe bets just years ago.[8]

The bottleneck is no longer generation but grid integration and storage. In a single year, 72 TWh of mostly renewable energy — equivalent to Austria's entire annual consumption — was curtailed due to grid bottlenecks alone.[9]

Rejuvenating grids while handling execution constraints

Europe’s power grids are in sore need of modernization. Roughly 40% of distribution networks are over 40 years old, and in the Netherlands almost 12,000 companies are waiting in line for connections.[10],[11]

The European Commission estimates €1.2 trillion of grid investment will be needed by 2040, and the burden is falling on operators ill-equipped to carry it.[12] Transmission system operators face external funding needs of around €250 billion by 2030, with German distribution system operators alone facing a roughly €70 billion equity gap over the next decade.[13],[14] Higher rates and construction costs make large projects harder to finance, and traditional models fall short for newer, higher-risk storage and distributed-generation work.[15]

Battery storage is one solution, but it is no panacea. European storage startups raised €2.14 billion in equity funding, but nearly half has already been deployed in the past three years.[16]

Even the power that gets built struggles to move across borders. Cross-border projects stall on cost-sharing disputes between member states.[17]

Unfortunately, costs could balloon over time. In particular, a skilled-labor squeeze is expected to tighten: upgrading the power grid could require 250,000 additional workers across Europe.[18] Competition for capital and skilled labor is set to intensify as countries around the world look to bolster their own power networks.  

Supply chains add another dimension. China holds around 85% of solar and 80% of lithium-ion battery production capacity with even higher shares for PV wafers and anode materials.[19] Nearly all EU-installed solar modules are Chinese-made, and the EU accounts for just 7% of global battery production; the IEA projects 70% of solar deployment will still have to be imported in 2030.[20] ,[21]

Ultimately, this will mean that there will be a need for more foreign direct investment in the sector: with European demand secured by policy and proximity, even Chinese manufacturers are keen to relocate production into Europe. Many will, however, look to carry out joint ventures with established energy, transmission and battery energy storage companies that have the regulatory approvals and established infrastructure in place.

The gap between what Europe's energy transition efforts requires and access to capital from conventional channels is a growing problem.

Alternative capital – including equity-backed finance – can help to close the funding gap. For clean energy entrepreneurs with equity holdings in their portfolio, share-backed lending can provide additional liquidity without sacrificing long-term upside potential.

The pieces are in place: growing demand, a policy tailwind and a clear commercial opportunity in grids and energy storage. What remains scarce is capital.
