Feasibility app glossary
This glossary explains the terms used in GIA’s feasibility app. The app supports initial exploration of project assumptions. Its outputs are indicative and depend on the inputs and model methodology.
Discuss your requirements ↗Tariff
The price received per unit of electricity sold. Check the currency, unit, indexation and contractual or market basis of the assumption.
Capital expenditure
The modelled cost of developing and constructing the project. Distinguish construction, development and grid-connection costs and avoid counting an item twice.
Capacity and generation
Capacity describes rated output, usually in MW or MWp. Generation is energy produced over a period, usually in MWh; the two measures are not interchangeable.
Operating expenditure
Recurring costs of operating and maintaining the project, based on the scope and timing assumed in the model.
Debt service coverage ratio (DSCR)
A ratio comparing cash available for debt service with scheduled debt service for a defined period. Read this output alongside the model’s cash-flow definitions and period settings.
Minimum and maximum DSCR
The lowest and highest DSCR values across the periods included in the calculation. Financing requirements depend on the agreed transaction terms; the displayed maximum is not a universal lender target.
Internal rate of return (IRR)
A calculated return based on the modelled cash-flow series. Specify whether the output relates to project cash flows or equity cash flows and how the model treats timing.
Net present value (NPV)
The value of a specified cash-flow series discounted at an assumed rate. The result depends on the cash flows, discount rate and timing convention.
Cash flow
Cash receipts less payments for a defined period. Check which operating, investing and financing items are included in the displayed measure.
Debt outstanding
The remaining loan principal at a given date, after the drawdowns and repayments reflected in the model.
Solar output profile
The pattern of modelled generation over time. Check the source, units, time resolution, system configuration and treatment of losses.
Interpreting an indicative assessment
Review the model methodology and assumptions before relying on an output. A screening model does not replace project-specific feasibility work, technical assessment or financing due diligence.
GIA pre-feasibility tool
Explore the economics
of a solar or wind project.
Test how project costs, energy assumptions, tariffs and financing affect indicative cash flows. Use the results to frame the next conversation with your project team.
Designed for early screening, with GIA advisory support available for detailed feasibility and investment decisions.
