How do I evaluate potential revenue streams from energy storage assets?

Evaluating potential revenue streams from flexible assets, such as energy storage systems, is not simple. Investors need to consider the various value pools available to a storage asset, including wholesale, grid services, and capacity markets, as well as the inherent volatility of the prices of each (see sidebar, “Glossary”).

Are electricity sales taxable?

The two largest revenue streams from producing electricity through renewable sources are electricity sales and renewable energy certificates (REC). The sale of electricity is typically taxable except in states with exemptions. An exemption taxpayers should examine is whether electricity is at retail or for resale.

Should energy storage be included in the electric grid?

Integrating storage in the electric grid, especially in areas with high energy demand, will allow clean energy to be available when and where it is most needed. As New York continues to invest and build a cleaner grid, energy storage will allow us to use existing resources more efficiently and phase out the dirtiest power plants.

Does a bundled electricity sale qualify for a sales tax exemption?

If sold together in a bundled transaction, taxpayers should determine whether the electricity or REC is the true object of the transaction. Taxpayers with battery storage at their facility should determine whether storing and releasing electricity could qualify for a production exemption from sales tax.

Should energy storage be undervalued?

The revenue potential of energy storage is often undervalued. Investors could adjust their evaluation approach to get a true estimate—improving profitability and supporting sustainability goals.
