Energy assumptions

Default energy assumptions

General

1. Storage To Generation Ratio: 1.5

2. Backup To Primary Generation ratio: The percentage of energy assumed to be generated by the backup generator as part of the total energy generation under normal operation, defaults to 20% (frequency regulation, grid stability, overall Capex)V

Generation Method Dependent

Solar PV: (at 11 degrees)

• Install cost per kW: $1,800

• Maximum generation per square meter: 200 kWh

• One time cost: n/a

Solar PV: (at 30 degrees)

• Install cost per kW: $1,800

• Maximum generation per square meter: 200 kWh

• One time cost: n/a

CHP/Cogen:

• Install Cost per kW: $3,500

• Per kWh fuel cost: $0.10

HAWT (Wind Turbine): (Horizontal Axis Wind Turbine):

• Install cost per kW: $2,500

• Cut in: wind speed required for the turbine to move, defaults to 3 knots

• Cut out: wind speed that would cause the turbine to lock, defaults to 20 knots

• Capacity: Capacity of one turbine, defaults to 1.5 MW

• Blade length: Length of blade, defaults to 3.8 meters

Diesel Engine:
