FAQS about Energy Storage Project Investment Key Points

Why do energy storage projects need project financing?

The rapid growth in the energy storage market is similarly driving demand for project financing. The general principles of project finance that apply to the financing of solar and wind projects also apply to energy storage projects.

Should energy storage project developers develop a portfolio of assets?

12 PORTFOLIO VALUATION Developing a portfolio of assets can be seen as the inevitable evolution for energy storage project developers and private equity investors who are interested in leveraging their knowledge of the technology, expertise in project development, and access to capital.

How can the Department of energy improve the understanding of energy storage?

Valuation Models A critical role for the U.S. Department of Energy to improve the understanding of energy storage project and portfolio valuation is to continue to develop and make publicly available valuation models that serve the upcoming need of new and innovative roles in the energy storage market.

What economic inputs are included in the energy storage model?

The economic inputs into the model will include both the revenue and costs for the project. Revenue for the energy storage project will either be expressed as a contracted revenue stream from a PPA (Power Purchase Agreement), derived from merchant activity by the facility, or some combination thereof.

How do you value energy storage projects?

The central tool for valuing an energy storage project is the project valuation model. Many still use simple Excel models to evaluate projects, but to capture the opportunities in the power market, it is increasing required to utilize something with far greater granularity in time and manage multiple aspects of the hardware.

Are energy storage systems a good investment?

This is understandable as energy storage technologies possess a number of inter-related cost, performance, and operating characteristics that and impart feed-back to impacts to the other project aspects. However, this complexity is the heart of the value potential for energy storage systems.
