Despite a projected tripling in investments from TSOs for the grid in Europe, a €250 billion ($293.3 billion) gap remains between expected operating cash flows and required capex through 2030, according to a report from Boston Consulting Group (BCG).
According to the report, Navigating Growth: Capital Challenges and Strategic Decisions for Europe’s Electricity TSOs, over the next five years, the 15 largest TSOs are projected to invest €345 billion ($404.8 billion), nearly tripling the amount deployed in the preceding five years.
BCG estimates that 2024 capital expenditures alone are approximately 50% higher than the year before and TSOs are mobilising all available funding levers—including debt, equity, and asset sales—to keep pace with demand.
However, with this explosive growth in investment, TSOs face a looming capital shortfall.
The BCG Center for Energy Impact analysis says that, without new approaches to financing and capital efficiency, TSOs may fall short of delivering the infrastructure needed to meet Europe’s climate and reliability goals.
In total, this shortfall comes to a €250 billion capital gap between expected operating cash flows and required capex through 2030.

Financial model pressures
According to BCG in a statement, despite clear signals that investment needs to scale, the current financial model underpinning Europe’s TSOs is experiencing considerable pressure.
BCG lists three core tensions.
Firstly, there is an issue of scale versus funding capacity. TSOs, says BCG, are remunerated based on spending levels, but many have stretched balance sheets and have already raised equity. Delivering large-scale infrastructure without jeopardising credit ratings or incurring equity dilution remains a central challenge.
Secondly, affordability versus returns. According to BCG, while policymakers aim to keep energy costs low for consumers, private investors require competitive, risk-adjusted returns. This leads to a persistent tug-of-war between cost containment and capital attraction.
Thirdly, growth mandate versus bond proxy. BCG says that TSOs are expected by policymakers to behave like growth companies—fast, scalable, and flexible—while many investors continue to value them as low-risk, dividend-paying entities. This mismatch is at the heart of diverging expectations around risk and return.
Strategic choices
The BCG report advises European TSOs to adjust their strategic footing through the following:
- Reassess ownership models: Leaders must determine optimal combinations of government ownership, public markets, and private capital (including infrastructure funds) to secure long-term support.
- Explore alternative financing: TSOs should look beyond traditional funding to mechanisms that preserve balance sheets and minimise dilution, such as minority stake sales or government-backed financing tools.
- Refine the portfolio: TSOs should reassess the geographic and business composition of their portfolios and consider divesting non-core assets to reallocate capital.
- Improve capital efficiency: Delivering more with less is imperative: controlling costs, accelerating project timelines, and prioritising high-impact, capital-efficient investments.
- Sharpen investor messaging: TSOs must position themselves as disciplined, well-governed infrastructure businesses that offer reliable long-term value creation, even amid volatility, in a context of competition for capital.
On the side of policymakers, the report adds that governments and regulators must also evolve their frameworks by ensuring clarity on how costs are shared between taxpayers and ratepayers, adapting regulatory frameworks to reflect the scale and complexity of infrastructure delivery, and deepening collaboration alongside TSOs.
