Hybrid System costs#
Hybrid system costs are costs that apply to the entire hybrid system. These costs are in addition to subsystem costs defined on the Installation costs and Operating costs input pages of each subsystem.
Installation Cost#
The installation cost of each subsystem is the total installed cost from each subsystem’s Installation costs page:
Installation costs apply to Year 0 of the project cash flow.
- Hybrid installation cost, $
The hybrid installation cost is for any costs associated with the hybrid system that are not included in the subsystem installation costs.
- Total installed cost, $
The sum of the hybrid installation cost and subsystem installed costs. This is treated as the Year 0 installation cost in the project cash flow.
Operation and Maintenance costs#
Operation and maintenance costs are annual operating costs that apply once the system starts operating in Year 1 of the project cash flow. Subsystem operating costs are specified on the Operating costs page for each subsystem. The hybrid operating costs are for any operating costs associated with the hybrid system that are not included in the subsystem operating costs.
- Hybrid fixed annual cost ($/yr)
A fixed annual cost that applies to each year in the project cash flow.
- Hybrid fixed annual cost by capacity ($/kWac-yr)
A fixed annual cost proportional to the hybrid system capacity from the Hybrid System page.
- Hybrid variable cost by generation ($/MWhac)
A variable annual cost proportional to the hybrid system’s total annual electrical output in AC megawatt-hours.
