What is NREL's solar-plus-storage cost benchmarking work?

This work has grown to include cost models for solar-plus-storage systems. NREL's PV cost benchmarking work uses a bottom-up approach. First, analysts create a set of steps required for system installation.

How do you convert kWh costs to kW costs?

The $/kWh costs we report can be converted to $/kW costs simply by multiplying by the duration (e.g., a $300/kWh, 4-hour battery would have a power capacity cost of $1200/kW). To develop cost projections, storage costs were normalized to their 2022 value such that each projection started with a value of 1 in 2022.

Are battery storage costs based on long-term planning models?

Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.

How does a solar PV project finance?

Debt Financing Structure: Solar PV projects often utilize project finance structures involving a syndicate of lenders. Model debt terms including senior and subordinated tranches, interest rates (fixed vs. floating), tenors, debt sculpting, interest rate hedging mechanisms, and grace periods.

What should be included in a solar PV financial model?

Before diving into the numbers, it is essential to define the scope of the financial model and establish all underlying assumptions. A comprehensive solar PV financial model should typically include the following key parameters: – Project Capacity: Specify the capacity of the solar PV system in megawatts (MW_DC and MW_AC).

Why is a financial model important for a solar PV project?

The growing adoption of renewable energy is driving a global transformation in how we produce and consume power, with solar photovoltaics (PV) leading the charge. Building a robust financial model for a solar PV project is crucial for evaluating project feasibility, managing complex risks, and ensuring investor confidence.
