Collective procurement of energy storage batteries

What is a battery energy storage system checklist?

Checklist provides federal agencies with a standard set of tasks, questions, and reference points to assist in the early stages of battery energy storage systems (BESS) project development.

What are the operational limitations of energy storage?

Operating Limitations: Energy storage resources may be subject to operational constraints that do not affect traditional generation projects. For example, certain battery technologies will degrade more quickly if the state of charge is not actively managed within a certain range.

What are the implications of a combined renewables-plus-storage project?

There will be important implications for a combined renewables-plus-storage project depending upon whether the project is DC coupled or AC coupled. For example, AC coupled systems are generally viewed as being simpler since the renewable energy storage can be connected separately with AC power.

Are battery degradation profiles a risk?

For many novel technologies or new battery chemistries, the degradation profiles have not yet been fully developed so there is some element of risk. Operating Limitations: Energy storage resources may be subject to operational constraints that do not affect traditional generation projects.

How do energy storage contracts work?

For standalone energy storage contracts, these are typically structured with a fixed monthly capacity payment plus some variable cost per megawatt hour (MWh) of throughput. For a combined renewables-plus-storage project, it may be structured with an energy-only price in lieu of a fixed monthly capacity payment.

Are solar manufacturers circumventing antidumping and countervailing duty orders?

The solar market was further constrained by an ongoing petition before the US Department of Commerce alleging that certain solar manufacturers in Southeast Asia were circumventing antidumping and countervailing duty (AD/CVD) orders on solar cells and modules from China.
