Introduction to Power Plant Insurance
Power generation facilities represent some of the most valuable and complex industrial assets in existence. A single combined cycle gas turbine plant may cost over $1 billion, while a nuclear facility can exceed $10 billion. Protecting these assets requires sophisticated insurance solutions that address the full spectrum of operational, physical, and financial risks.
The power generation sector is undergoing its most significant transformation in a century. The shift from fossil fuels to renewables, the decentralization of generation, and the integration of energy storage technologies are fundamentally changing the risk landscape. Modern power plant insurance programs must evolve to address these emerging challenges while continuing to protect traditional thermal assets.
This guide provides a comprehensive overview of power plant insurance, examining coverage options for all facility types, from coal and natural gas plants to solar, wind, and emerging technologies like green hydrogen production.

Core Coverage Components
Power plant insurance programs typically integrate several coverage components into a comprehensive package. The structure varies based on plant type, ownership, power purchase arrangements, and regulatory requirements.
Standard Coverage Structure
Property All Risks
Physical damage coverage for buildings, equipment, and infrastructure on an all-risk basis subject to standard exclusions.
Machinery Breakdown / Boiler & Machinery
Covers sudden and accidental breakdown of mechanical and electrical equipment including turbines, generators, and transformers.
Business Interruption
Covers lost revenue and continuing expenses when covered physical damage interrupts power generation.
General Liability
Third-party liability for bodily injury and property damage arising from plant operations.
Environmental Liability
Pollution coverage for cleanup costs and third-party claims from environmental contamination.
Machinery Breakdown Coverage
Machinery breakdown coverage is the cornerstone of power plant insurance. This coverage addresses sudden and accidental equipment failures that standard property policies exclude or limit. For power plants, where individual components can cost tens of millions of dollars, this coverage is essential.
Covered Equipment
- Gas and steam turbines
- Generators and alternators
- Transformers (GSU, aux)
- Heat recovery steam generators
- Boilers and pressure vessels
- Compressors and pumps
- Control systems (DCS/SCADA)
- Electrical switchgear
Common Causes of Breakdown
- • Turbine blade failures and rotor damage
- • Generator winding failures and core damage
- • Transformer internal faults and bushing failures
- • Control system malfunctions causing physical damage
- • Vibration-induced fatigue failures
- • Electrical arcing and short circuits
Critical Considerations
- • Lead times for replacement components can exceed 18-24 months for major equipment
- • Deductibles for gas turbines and generators are typically $1-5 million
- • Some policies exclude damage during maintenance or startup sequences
- • Coverage for manufacturer defects may require negotiation
Business Interruption Coverage
Business interruption coverage is particularly critical for power plants where extended outages can result in losses far exceeding physical damage costs. With replacement equipment lead times measured in months or years, BI coverage often represents the largest component of a power plant claim.
Coverage Elements
Gross Profit / Revenue
Lost revenue from power sales during the interruption period
Standing Charges
Fixed costs that continue during shutdown (debt service, labor, etc.)
Increased Cost of Working
Expediting costs, temporary power purchases, emergency repairs
Contingent BI
Losses from damage at suppliers (fuel) or customers (grid)
Indemnity Periods
Given equipment replacement timelines, power plants typically purchase 24-36 month indemnity periods. Combined cycle plants may require longer periods due to gas turbine and HRSG lead times. Nuclear plants often carry extended indemnity periods exceeding 36 months.
Waiting Periods / Time Deductibles
BI coverage typically includes waiting periods of 30-90 days before coverage attaches. This aligns with planned maintenance outages and reduces premiums. Some policies offer buy-down options for shorter waiting periods.
Liability Coverage
Power generation facilities face significant liability exposures from plant operations, environmental risks, and grid interconnection. Comprehensive liability coverage is essential for protecting operators against third-party claims.
General Liability
Covers third-party claims for bodily injury and property damage arising from plant operations. This includes injuries to visitors, contractors, and damage from plant-originating incidents affecting neighboring properties.
Pollution Legal Liability
Power plants face environmental exposures from:
- • Fuel storage and handling (coal, oil, gas)
- • Cooling water discharges
- • Air emissions and stack releases
- • Coal ash and waste disposal
- • Transformer oil and hazardous materials
Transmission & Distribution Liability
Coverage for claims arising from grid interconnection, including voltage fluctuations, power quality issues, and outages affecting grid customers. This is particularly relevant for renewable generators with intermittent output.
Renewable Energy Specifics
Renewable energy generation presents distinct risk profiles compared to conventional thermal plants. Insurance solutions have evolved rapidly to address the unique characteristics of solar, wind, and energy storage installations.
Solar PV Insurance Considerations
- • Panel degradation and performance warranties
- • Inverter reliability and availability
- • Hail and severe weather exposure
- • Tracker system mechanical failures
- • Theft and vandalism (remote locations)
- • Wildfire exposure and evacuation costs
Wind Farm Insurance Considerations
- • Blade failures and lightning damage
- • Gearbox and drivetrain reliability
- • Foundation and tower integrity
- • Crane and heavy lift availability
- • Bird and bat mortality claims
- • Ice throw and debris projection
Battery Energy Storage (BESS)
- • Thermal runaway and fire risk
- • Cell degradation and capacity fade
- • Power conversion system failures
- • Grid code compliance
- • Evolving technology risk
- • Limited loss history for pricing
Nuclear Plant Coverage
Nuclear power plants operate under unique regulatory frameworks with specific insurance requirements. Most conventional insurers exclude nuclear risks, requiring operators to obtain coverage from specialized nuclear insurance pools.
Nuclear Insurance Framework
Nuclear Liability Insurance
Required under the Price-Anderson Act (US) and similar legislation globally. Covers third-party claims from nuclear incidents through industry mutual pools (e.g., NEIL, EMANI).
Nuclear Property Insurance
Covers physical damage to the plant including equipment breakdown and decontamination costs. Available through nuclear pools only.
Nuclear Business Interruption
Extended indemnity periods (often 36+ months) reflecting long regulatory restart processes following nuclear incidents.
Key Nuclear Pools
- • NEIL (Nuclear Electric Insurance Limited) - US mutual
- • EMANI (European Mutual Association for Nuclear Insurance)
- • NIA (Nuclear Insurance Association of Canada)
- • Japan Nuclear Insurance Pool

Market Trends 2025
Energy Transition Pressures
Some insurers are limiting capacity for coal plants, and thermal capacity faces ESG-driven restrictions. Renewable energy assets are seeing increased competition for coverage with generally favorable terms.
BESS Market Development
Battery storage insurance remains challenging with several high-profile thermal runaway incidents affecting the market. Fire suppression requirements and cell chemistry are key underwriting considerations.
Nat Cat Exposure
Increasing severe weather events are driving higher natural catastrophe rates, particularly for facilities in hurricane, wildfire, and flood zones. Climate modeling increasingly informs capacity deployment.
Supply Chain Concerns
Extended lead times for major equipment (turbines, transformers) are driving increased focus on BI valuations and spare parts arrangements. Contingent BI for critical suppliers is receiving greater attention.
Frequently Asked Questions
What is the difference between property and machinery breakdown coverage?
Property coverage protects against external perils like fire, weather, and physical damage from named causes. Machinery breakdown covers internal equipment failures—sudden mechanical or electrical breakdowns that property policies typically exclude. Power plants need both coverages as they face both types of exposures.
How is business interruption valued for power plants?
BI values are calculated based on expected power sales revenue, capacity payments, and renewable energy credits minus variable costs avoided during shutdown. Power purchase agreement (PPA) terms significantly influence valuation. Plants with merchant exposure face additional volatility considerations.
Why do power plants have such high deductibles?
High deductibles ($1-5 million for major equipment) reflect the frequency of smaller equipment issues, the high values at risk, and premium considerations. Operators often retain routine maintenance-type losses while insuring catastrophic and major equipment failures.
Can coal plants still obtain insurance coverage?
Yes, though capacity is increasingly constrained as some insurers adopt ESG-driven underwriting restrictions. Coal plants may face higher premiums and more restrictive terms. Operators should work with specialized energy brokers who maintain relationships with remaining coal-friendly markets.
What coverage is available for battery storage systems?
BESS coverage includes property all risks, machinery breakdown, business interruption, and liability. Underwriters focus on battery chemistry, fire suppression systems, spacing, and thermal management. Coverage may include sub-limits for thermal runaway events. The market is still developing as loss experience accumulates.
