While energy storage is already being deployed to support grids across major power markets, new McKinsey analysis suggests investors often underestimate the value of energy storage in their business cases.
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”).
Simultaneously, wind farms equipped with energy storage systems can improve the wind energy utilization even further by reducing rotary back-up . The combined operation of energy storage and wind power plays an important role in the power system's dispatching operation and wind power consumption .
In order to comprehensively consider the impact of the energy storage life on the system income, it is also converted into the annual equivalent recovery amount, and the calculation formulas are as follows: (22) f R = σ × k P P B + k E E B × SFF (23) SFF = r 1 + r L B 1 where σ is equipment residual value residual rate, SFF is sinking-fund factor.
The calculation method of annual operation and maintenance cost of energy storage is as follows: (21) f O = k PO P B + k EO E B where kPO is annual operation and maintenance cost of energy storage unit power, kEO is annual operation and maintenance cost of energy storage unit capacity.
Such complexity means the expected economic returns are often undervalued, especially if shortcuts are taken to simplify the analysis. Adopting a holistic approach that considers all revenue streams across a broad range of external events could improve the outlook of energy storage returns.
