Renewable Energy Insurance
Renewable energy facilities rest on different physical processes and do not fit a single insurance mould. This page maps the renewable energy portfolio and covers the insurance risks of technologies that do not have a separate page — hydropower, bioenergy and waste-to-energy, geothermal and marine energy. Policy types such as CAR/EAR during construction and OAR/PD, MB and BI during operation are combined according to the technology; not every cover applies automatically to every facility.
We have detailed pages for solar, wind, storage and offshore: Solar Energy Insurance, Wind Energy Insurance, Battery Energy Storage Insurance and Offshore Energy Insurance. For the general coverage structure see the Energy Insurance page. This page is general information; it does not imply the capacity of any particular insurer, acceptance of cover, price or any commitment to pay.

Hydropower Plants
Hydropower uses the energy of water; dams and water structures, tunnels and penstocks, turbines and electrical equipment are together the subject of insurance. Hydrological conditions (water flow) are treated as a separate risk outside property damage cover.
Scroll the table horizontally to see all columns.
| Risk focus | Insurance point to note | |
|---|---|---|
| Dam-type (reservoir) hydropower | Dam body, spillway, reservoir, flood and overtopping, geological conditions, earthquake | A dam failure or uncontrolled release may cause third-party loss downstream; liability limits and scope are examined separately |
| Run-of-river hydropower | Intake structure, weir, sediment and debris, flood | The sublimit and deductible structure for flood damage depends on the policy; the cost of clearing silt and debris after a flood should be confirmed separately, and gradual sediment build-up is generally not an insurable loss |
| Pumped-storage hydropower | Two reservoirs, reversible pump-turbine, fatigue from frequent cycling, long underground structures | Construction is long; geological uncertainty and tunnelling are assessed separately in the construction policy |
| Micro and small hydropower | Flood sensitivity, small-scale equipment, remote location | Loss frequency may be relatively high; deductible and access conditions stand out |
- Turbine and generator: Cavitation, wear, bearing failure; the distinction between cavitation wear and sudden damage depends on the policy terms.
- Penstock and tunnel: Penstock damage, rupture or leakage; where such an event causes third-party or environmental damage downstream, that is a separate liability matter.
- Flood: Flood may be assessed within natural catastrophe sublimits; the scope of sediment and debris clearance costs should be confirmed in the policy.
- Mechanical breakdown and business interruption: MB and BI/MLOP structure; a drop in water flow alone is not a BI trigger.
- Construction: For tunnel, dam and underground works, the geological report and construction method are underwriting topics. See Construction & Erection Insurance.
- Environment: For water quality and ecological effects see Environmental Impairment Liability.
Bioenergy and Waste-to-Energy
Bioenergy facilities generate electricity, heat or fuel from organic material or waste. The risk profile differs from coal or natural gas plants: fire and explosion, the biological process, feedstock continuity and environmental liability are assessed together.
Scroll the table horizontally to see all columns.
| Main risk focus | Point to note | |
|---|---|---|
| Biogas | Digester, gas holder, methane leakage, gas engine | Fire/explosion and gas engine MB; failure of the biological process itself (such as foaming or loss of yield) is not standard property damage and is assessed under the policy only if it causes sudden physical damage; interruption of the biological process alone does not trigger BI |
| Biomass (combustion) | Fuel storage and self-ignition, dust explosion, boiler corrosion | Solid-fuel boiler risk; fuel supply interruption is not a BI trigger |
| Waste-to-energy (WtE) | Waste feed, furnace and grate, flue gas treatment, boiler and turbine | Environmental non-compliance and pollution liability are assessed separately |
| Biomethane | Upgrading biogas to a high methane content, compression, grid injection | Pressurised gas and upgrading equipment; flammable gas fire and explosion |
| Landfill gas (LFG) | Gas collection wells, pipe network, flare, movement of the landfill | Separate responsibilities of the site owner and the gas project operator; fire and settlement at the site |
| Biofuels (biodiesel, bioethanol) | Flammable liquids, fermentation and distillation, grain dust explosion | Process fire/explosion, storage and product liability |
- Biogas versus biomass: Biogas produces gas through anaerobic digestion and runs a gas engine; biomass burns or gasifies solid fuel. Policy structures and risks differ; they cannot be assessed within the same framework.
- Feedstock continuity and quality: Interruption of feedstock supply alone does not trigger BI; a physical damage trigger is required. Foreign matter in feedstock can damage equipment.
- Waste processing for energy: The stages of shredding, drying or converting waste into fuel (for example preparing waste-derived fuel) carry high fire and mechanical damage risk.
- Environmental liability: Methane leakage, digestate or leachate, flue gas emissions and odour-related third-party claims. See Environmental Impairment Liability.
- Machinery breakdown: Failures of gas engines, mixers, pumps, compressors and treatment units.
Geothermal Energy
Geothermal facilities use hot subsurface fluid; while the surface plant resembles a conventional energy facility, the subsurface resource (reservoir) and well risk add a separate dimension. Türkiye is among the leading geothermal power-producing countries in the world; for the current ranking and capacity, up-to-date data from sources such as IEA and IRENA should be consulted.
Scroll the table horizontally to see all columns.
| Main risks | Cover approach | |
|---|---|---|
| Drilling | Drilling equipment damage, well control, loss of well, high temperature and pressure, H₂S | Special assessment dependent on the drilling programme and well information; well control cover does not apply automatically |
| Well and reservoir | Wellhead integrity, well integrity, decline in reservoir productivity | Decline in reservoir productivity is outside standard property damage cover; queried separately |
| Plant and heating systems | Turbine erosion, heat exchanger, corrosion and scaling, pipeline | OAR/PD, MB and BI/MLOP; a different income structure for direct heat use such as district heating |
| Environment and third parties | Uncontrolled surface release of fluid, H₂S, soil and water contamination | Environmental and liability cover separately |
- Enhanced geothermal systems (EGS): A technology of limited commercial spread that creates artificial fractures in rock to enable fluid circulation; additional risks such as injection-related induced seismicity and third-party claims are discussed. Insurability is project-specific.
- Closed-loop geothermal: Newer technologies in which fluid circulates in closed pipes underground; maturity and loss experience are limited and no established insurance structure exists.
- Geothermal heating: Direct heat use in greenhouses, housing and district heating; scaling, corrosion and pump failures stand out.
Hybrid Renewable Facilities
In facilities that combine several renewable technologies or storage at a shared grid connection, shared infrastructure (transformer, switchgear, control system) can let damage to one component affect another. Value allocation, the BI trigger and a single or separate policy structure should be clear in the policy. See the relevant pages for solar and wind components and the BESS page for storage.
Marine Energy Technologies
The technological maturity and commercial viability of systems that generate energy from waves, tides, ocean thermal energy (OTEC) and salinity gradients differ from one another. For most of these technologies the stage of development is limited; insurability is specific to the project and the technology.
Scroll the table horizontally to see all columns.
| General stage of development | Insurance note | |
|---|---|---|
| Tidal stream | Generally a limited number of commercial-scale and demonstration projects | Marine environment, installation vessels and cable risks; assessment similar to offshore structures |
| Wave | Generally at demonstration and pilot stage | Loss experience and market practice are limited; project-specific assessment |
| OTEC | Generally pilot and small scale | Large water intake pipes and marine structures; no established insurance structure |
| Salinity gradient | Generally laboratory and pilot stage | Commercial-scale application is limited; insurability has not been verified |
This table is a general framework; the stage of development and capacity position of a specific project should be verified from the relevant technical sources and the insurer's assessment. No standard policy or capacity should be assumed for any marine energy technology.
Policy Structure and Technology-Specific Notes
- CAR / EAR and DSU/ALOP: Construction and erection; tunnel and dam works in hydropower, drilling in geothermal (well and drilling risks are mostly assessed under separate drilling and well-control covers outside CAR/EAR) and process equipment erection in bioenergy bring different underwriting topics.
- OAR/PD and MB: Operational property damage and machinery breakdown; technology-specific mechanisms such as wear and cavitation, corrosion and scaling depend on how the policy treats them.
- BI/MLOP: Water flow, feedstock supply or reservoir productivity alone is not a trigger; a physical damage trigger is required. See Business Interruption Insurance.
- Liability and environment: Dam liability, pollution and odour claims; separate liability and environmental cover may be needed.
- Cyber / OT: The cyber exclusion should be assessed separately for control systems. See Cyber Insurance.
- Parametric structures: For resource risks such as water flow, irradiation or wind see Parametric Insurance.
Licensing and Insurance in Türkiye
In Türkiye, electricity generation is mostly within the EPDK licensing framework (exemptions for unlicensed generation are assessed separately); water-use rights for hydropower, resource licences for geothermal and environmental permits for bioenergy and waste-to-energy facilities are subject to the regulations of the relevant authorities. A licence, an administrative or financial guarantee, a financing-agreement requirement and an insurance-policy obligation are separate concepts; this page neither asserts that a licence or guarantee in itself creates an insurance obligation nor states categorically that it does not. Insurance provisions in the relevant licence, permit and contract texts should be examined separately. Financing institutions generally require specific insurance covers in their agreements.
