Summary report on energy storage project supervision work

What is the purpose of the energy storage review?

The Review is intended to provide a briefing regarding a range of energy storage technologies that includes a detailed listing of primary sources. For that reason, Microsoft® Word, rather than PowerPoint, was used for producing the Review.

Why are energy storage technologies undergoing advancement?

Energy storage technologies are undergoing advancement due to significant investments in R&D and commercial applications. For example, work performed for Pacific Northwest National Laboratory provides cost and performance characteristics for several different battery energy storage (BES) technologies (Mongird et al. 2019). Figure 26.

Why do system planners need to plan a battery storage system?

As regulators provide more incentives for the viability of battery storage to provide capacity and energy, system planners must adequately plan the system for a projected large increase in BESS, understanding the impact of size, location, and operating characteristics on maintaining the reliable operation of the grid.

How can we improve energy storage based on grid and integration benefits?

Improve techno-economic modeling tools to better account for the different fossil thermal power plants and their characteristics and expand their storage technology representations to allow for quantitatively evaluating the benefits of energy storage based on grid and integration benefits.

What is co-located energy storage?

Co-located energy storage has the potential to provide direct benefits arising from integrating that technology with one or more aspects of fossil thermal power systems to improve plant economics, reduce cycling, and minimize overall system costs. Limits stored media requirements.

What is the worldwide electricity storage operating capacity?

Worldwide Electricity Storage Operating Capacity by Technology and by Country, 2020 Source: DOE Global Energy Storage Database (Sandia 2020), as of February 2020. Worldwide electricity storage operating capacity totals 159,000 MW, or about 6,400 MW if pumped hydro storage is excluded. The DOE data is current as of February 2020 (Sandia 2020).
