Power Generation Plants – Risk Profile and Loss Prevention

Risk drivers

Power plants concentrate high asset values on a comparatively small footprint in the form of turbine generator sets, boilers, transformers and switchgear. Failure of a single major component – such as a main generator or generator step-up transformer – can cause business interruption of several months due to long replacement lead times, regardless of whether the facility is a thermal plant, wind farm, solar plant or hydroelectric station. In addition, combustible operating media such as turbine lubricating oil, hydrogen-cooled generators and extensive cable installations can rapidly expose several plant areas simultaneously in the event of fire.

Protection concept

A risk-adequate protection concept combines automatic suppression for transformers and turbine halls, redundant protection and control systems, tested emergency power supply for safety functions, and a structured condition monitoring programme for rotating machinery. Because each generation technology – thermal, wind, solar, hydro – carries its own additional hazards, technology-specific measures complement the shared baseline protection concept.

Insurance relevance

Given the high value concentration and long replacement times for critical components, maximum foreseeable loss analysis is a central element of every risk survey at power plants. Property and machinery insurers regularly require documented maintenance programmes and spare-parts strategies for key components as a condition for risk-adequate cover.
