Economic, technical, and geopolitical risks impact on electricity supply [56].

Hazard Energy system Impact
Economic risks
Unexpected increase in energy price Green Electricity Bioelectricity The price of the fuel used to generate electricity is likely to change leading to uncertainty as to the cost of production.
Interruption or reduction of international energy supply. Energy cuts have a significant impact on national accounts, and can lead to an increase in inflation, trade and wage imbalances, high unemployment, low consumer safety
Disruption of domestic and local energy supplies. Possibility of disrupting domestic energy supply due to local and temporary problems which may be adverse weather events, strikes and/or accidents
Gradual reduction of biofuels stocks Economic pressures create minimization trends in commercial fuel stocks (both in the distribution chain and in the place of use) and storage capacity in production units and transmission systems
Technical risks
Uncertainty in the supply of biofuel to a power plant Green Electricity Bioelectricity Fuel adequacy in a power plant may be unreliable leading to inability to produce. The supply of fuel depends both on its availability and on the reliability of the mode of transport
Engineering problems and equipment failures   Requirement of periodic maintenance
Geopolitical risks
Reforms in environmental legislation affecting energy supply Green Electricity Bioelectricity Non-compliance with existing laws and regulations on environmental protection against the effects of electricity generation and compliance costs are quite high. This risk depends largely on the fuel and technology used for production.
