How insurers can scale their offerings to support the green energy transition

As the race to net zero accelerates, insurers find themselves in a pivotal position. Governments and investors are committing significant capital to renewable and low-carbon technologies, while developers push ahead with increasingly complex and capital-intensive projects. For insurers, this is not simply a question of supporting sustainability ambitions, but of responding to a rapidly evolving risk landscape with the right products, expertise, and operating models.

The role of insurance in the green transition is sometimes understated. In practice, insurers are already deeply embedded in the development of renewable energy projects, from early-stage feasibility through construction and into long-term operation. The challenge now is ensuring that insurance capabilities continue to evolve in line with new technologies, investor expectations, and regulatory scrutiny.

A proven role in enabling innovation

The insurance sector has long supported technological innovation by helping organisations understand, manage, and transfer risk. The green energy transition is no exception. From large-scale solar and wind projects to more experimental technologies, insurers have played a critical role in enabling projects to move from concept to execution.

This early engagement has been key. By working with developers and sponsors at the outset, insurers have supported feasibility assessments, delivered risk workshops, carried out climate and catastrophe modelling, and tested supply chain resilience. These activities help shape more robust project designs and provide greater confidence to investors and lenders.

This approach has delivered results before, and it remains just as relevant as the pace of innovation accelerates. As renewable technologies diversify and project structures become more complex, early and informed risk input is increasingly valuable.

Supporting projects across the full lifecycle

Insurers’ value does not stop once a project reaches financial close. Across the lifecycle of a green energy project, insurance plays a central role in de-risking investment and supporting operational stability.

At the financing stage, insurers can support bankability through performance warranties and parametric solutions that help manage revenue volatility. These mechanisms are particularly important where returns are sensitive to environmental variables such as wind speed, solar irradiance, or temperature.

During construction, Construction All Risk and Engineering All Risk policies can be tailored to cover complex assets including turbines, subsea cables, offshore infrastructure, and marine logistics. As projects move into operation, broader operational covers come into play, addressing property damage, business interruption, machinery breakdown and, where relevant, political risk exposure.

The breadth of this support is already well established. The challenge for insurers is not a lack of products but ensuring that offerings remain fit for purpose as technologies, project structures and risk profiles continue to evolve.

Bespoke solutions for emerging technologies

As the energy mix diversifies, standardised approaches are increasingly insufficient. Technologies such as hydrogen, energy storage and battery energy storage systems introduce new and often unfamiliar risks. These include thermal runaway, complex interdependencies between assets, and evolving regulatory and safety standards.

Parametric insurance has emerged as a powerful tool in this context, providing structured and transparent protection against resource variability and operational disruption. However, parametric solutions are only one part of the picture. Insurers also need to develop specialist wordings, underwriting frameworks and risk models that reflect the specific characteristics of emerging technologies.

This requires close collaboration between underwriting, risk, engineering, and actuarial teams, supported by robust data and modelling capability. As projects scale, so too does the need for confidence that insurance coverage genuinely reflects the risks being transferred.

What insurers should focus on next

As we enter into 2026, there are several areas where insurers should concentrate their efforts to remain effective partners in the green energy transition:

• Reviewing portfolio exposure to emerging technologies, ensuring underwriting approaches reflect new risk profiles rather than legacy assumptions
• Strengthening product innovation, particularly in parametric and performance-based solutions that support project bankability
• Engaging earlier with developers and investors, allowing risk considerations to shape project design rather than react to it
• Enhancing data, modelling, and technical capability to support underwriting, pricing and claims assessment
• Ensuring policy wordings and risk frameworks can flex across jurisdictions, particularly as projects increasingly span multiple regulatory regimes

These priorities are not about reinventing the role of insurance, but about refining and scaling existing capabilities to meet new demands.

The outlook for 2026

The renewables sector will continue to evolve rapidly, driven by technological innovation, policy objectives, and investor appetite. In parallel, insurers will face growing expectations to demonstrate technical competence, consistency, and clarity in how they support these projects.

Hydrogen provides a clear example. As the sector matures, insurers that invest early in tailored wordings, risk assessment frameworks and advisory capability will be better positioned to support growth while managing downside risk. Similar dynamics apply across offshore wind, energy storage, and integrated renewable systems.

In this environment, insurers that succeed will be those that combine technical depth with operational discipline. Engaging early, listening closely to client needs and continuously adapting coverage and risk frameworks will remain essential.

For many insurers, external advisory support can play a valuable role in this process, bringing specialist expertise across risk, capital, modelling and regulation to help assess opportunities, design solutions, and build confidence in decision-making.
