The high-voltage risk environment

The price of transition: systemic risk

The energy transition is creating a more connected and more volatile risk landscape. Physical, regulatory, geopolitical and operational pressures now interact more quickly and with greater force. In this environment, resilience and insurance are not just protective. They are critical to growth.

The challenge is broadening:

Competing priorities: from governments, investors and insurers alike
Shifting ownership models: with new players unaware or underprepared for the risks they face
Operational and delivery obstacles: including novel operational liabilities, supply chain setbacks, shifting climate dynamics and grid constraints
Unpredictable, changing climate patterns creating physical risk: which can impact the reliability of some renewable energy sources

The organisations that succeed will be those that understand how these risks connect and plan for them early.

Risk is converging and so is complexity
Climate risk is becoming harder to model
The transition is moving at different speeds
Global growth comes with political risk
Operational resilience is under pressure
Insurability is now central to project viability

Risk is converging and so is complexity

Energy transition risks do not arrive one at a time. They combine and amplify. A climate event can damage an asset, disrupt local infrastructure, delay repairs and cut revenue at the same time.

Geopolitical shocks can do the same through supply chains, prices and capital allocation – as seen with the 2026 war in Iran choking critical shipping lanes in the Strait of Hormuz²⁵. That makes a joined-up risk view more valuable than managing each threat in isolation.

“Climate risks increasingly trigger second-order impacts, disrupting supply chains and driving effects such as inflation. These cascading risks extend far beyond physical damage and are now being integrated into regulatory and risk frameworks as their systemic financial implications become more pronounced.”

Energy transition threats do not act in isolation, they interact and amplify. Managing interconnected risks is as critical as addressing individual ones. The smart approach is to understand how risks converge, helping organisations prevent incidents from escalating into costly, long-term crises.

“Wind farm failures can cascade like fairy lights - if one element fails, connected assets within the string can shut down.”

Climate risk is becoming harder to model

For decades, hazard planning and insurance underwriting assumed extreme weather followed predictable patterns. That assumption is breaking down. Extreme weather is becoming more frequent, volatile and less predictable, from rapidly intensifying storms to severe wildfires across California²⁶.

As the frequency and severity of these events increase, climate models are struggling to keep pace. This leaves projects that were robust on paper more exposed to risks that can render them unfinanceable and uninsurable.

At the same time, renewable assets are often clustered in the same regions. This increases aggregation risk, where one event can affect multiple sites across a portfolio. As a result, scenario planning and insurance structures need to become more sophisticated.

“Scenario planning must account for sensitivity and correlation across variables, as climate pathways can change direction quickly. What appears manageable today may escalate or accelerate unexpectedly, requiring flexible strategies and methodologies to respond to evolving environmental and transition risks.”

David Singh
Head of Catastrophic Risk & Research, Beazley
The Sustainable Markets Initiative (SMI) notes that physical climate risks are notably underpriced. Near-term losses are expected in the trillions while 75% of institutional investors expect climate risks to hit asset prices within the next five years²⁷.

In the US, many large solar farms are spread across wide, exposed sites, so a single severe hailstorm can damage numerous panels. While the physical damage is immediate additional financial harm comes from dropped power generation, long repair delays, replacement costs and business interruption.

“Weather events previously modelled as rare are occurring more frequently, compressing return periods for solar farms for example, making hail a critical peril for insurers. The industry is still catching up to the new reality of what severe convective risk looks like for solar assets at scale.” Geoffrey Lehv, SVP, Head of North American Accounts, kWh Analytics (A Beazley company)

The transition is moving at different speeds

To keep up with the thriving renewable sector, the International Energy Authority (IEA) estimates the world must build or fix 80 million kilometres of power lines by 2040 – essentially replacing the entire global grid from scratch²⁸.

But growth is not evenly distributed. Some markets such as China are scaling faster²⁹ because they have stronger supply chains, lower costs or better infrastructure³⁰.

Others such as Europe and North America face slower permitting, older grids and higher build costs³¹. This creates a two-speed transition, where geography shapes both opportunity and exposure.

“Network interconnection and intermittency are not side issues in the energy transition. They are central to whether projects can connect on time, operate reliably and deliver the commercial returns investors, developers and insurers are relying on.”

New assets bring new uncertainty

New entrants are expanding across technologies and regions while still building their operating models and risk frameworks. That can make portfolio exposure harder to track.

Next-generation assets such as SMRs and fusion add further uncertainty. They offer growth potential, but they also bring less familiar technical, financial and regulatory risk³².

Meanwhile the use of PFAS and PFOA chemicals in solar and battery fire systems is drawing heavy regulatory scrutiny, and retroactive enforcement creates environmental liabilities that can haunt owners for decades.

“The liability profile of the energy transition is far broader than most investors realise. PFAS chemicals in fire suppression systems, historical contamination on brownfield sites, third-party bodily injury claims, these are not edge cases. They are live and growing areas of loss that require specialist underwriting, not standard property coverage.”

Global growth comes with political risk

Emerging markets offer strong demand and long-term growth potential³³, but they also bring currency volatility, weaker utilities, fragile grids and political uncertainty.

Developed markets carry different risks, including subsidy changes, tariffs and policy intervention. For firms operating across regions, resilience depends on diversification, political monitoring and specialist risk transfer.

Global energy market players should diversify income to absorb cost shocks and focus on tracking political change. Specialist political risk insurance adds protection against government actions, trade credit risks, terrorism and political violence.

Operational resilience is under pressure

Battery storage highlights the challenge. BESS can support flexibility and grid performance, but it also introduces distinct operational risks, including thermal runaway and fire.

More broadly, the energy transition still lacks long-term performance data in many areas. Rapid technology change is colliding with slower infrastructure cycles, increasing the risk of underperformance or stranded assets. Success depends on planning for the worst, not reacting to it. This requires the mapping of supply chains, pricing exposures, and embedding contingencies into operations by:

Building in buffers for delay and disruption
Identifying operational warning signs
Using parametric risk transfer tied to predefined climate event triggers
Improving frontline response strategies

“Scaling depends on faster permitting and infrastructure across Europe.”

Bureaucratic delays are creating an insurability problem

Permitting delays are slowing project delivery, especially in parts of Europe. This can also delay access to insurance, because underwriters often need final permits before they can quote.

That creates a bottleneck. If cover cannot be secured, financing can stall. As delays build, costs rise, capacity can tighten and investor confidence can weaken and even halt.

Insurability is now central to project viability

Demand alone does not make a project bankable. Insurance is often a condition of financing, which means insurability has become central to project delivery.
Without suitable cover, developers may struggle to unlock loans, release capital or move into construction. In practice, no quote can mean no project.

Insurance is entering into new territory

The growth of renewable and next-generation energy is a major moment for insurers, but it is also stretching traditional models:

Many new assets do not have long operating histories
Ownership structures are more fragmented
Regulation is evolving
Climate losses are increasing in frequency and severity

Traditional products were not built for this market. Property, marine and liability cover now need to respond to very different technologies and exposures.

Insurance must adapt to enable growth

To support the next phase of the transition, insurers need to do more than react. They need to work earlier and more closely with brokers, developers and governments to shape viable risk solutions. The market will need broader tools, better data and more collaborative underwriting. In this new energy system, insurance will not just protect projects, it will help make them possible.
