EIB and Commerzbank unlock €2 billion to fast-track Europe's grid expansion

The European Investment Bank (EIB) and Commerzbank have signed a new cooperation agreement at Hannover Messe that will enable up to €2 billion in investments in electricity grids across Germany and other EU member states, according to an EIB press release. At the heart of the deal is a €250 million EIB portfolio guarantee to Commerzbank, which frees up the bank’s regulatory capital and allows it to offer more guarantees to manufacturers of grid equipment — cables, transformers, and substations — helping remove a key financing bottleneck that has slowed grid expansion across Europe. EIB Vice-President Nicola Beer said without efficient grids, “wind turbines, solar panels and heat pumps go unused — we would miss the energy transition, literally sitting in gridlock.”

The scale of investment needed is enormous. Germany alone will require more than half a million additional kilometres of cables and transformers by 2045, with total grid investment projections reaching around €431 billion — roughly €20 billion per year, nearly four times the 2022 level. Grid bottlenecks are already costing the system dearly: in 2023, more than 27,000 GWh of electricity had to be balanced through costly redispatching measures, at a price tag of around €3.2 billion. Commerzbank Divisional Board Member Neil Aiken said the bank sees “every day how large the investment and financing needs for grid infrastructure are,” and that the EIB guarantee directly strengthens its capacity to address them.

The EIB guarantee works by covering up to 50% of the risk on performance and advance payment guarantees for equipment manufacturers — tools that protect grid operators from supplier failures on large contracts. Because Europe’s grid component market is dominated by a small number of large manufacturers, banks have been hitting concentration and regulatory risk limits, restricting how much financing they can offer. The EIB’s risk-sharing model breaks that logjam, following the same approach it has already applied in the wind energy sector with Commerzbank and others.

This deal is the first transaction under the new pan-European EIB Grid Package, a broader initiative designed to enable grid investments across the EU while also reinforcing the industrial supply chain for grid equipment. Each operation under the programme can mobilize up to €4 billion in additional grid investments. For humanitarian and development audiences, the implications are straightforward: resilient, affordable, and clean energy infrastructure is foundational to economic stability, industrial competitiveness, and the long-term sustainability of the communities that organizations like theirs work to support.
