What are the safety requirements for energy storage technologies?

Safety: Minimum safety and operating requirements are common considerations for energy projects. Energy storage resources present additional safety concerns given their unique technological profiles. For battery storage technologies in particular, safety requirements should adequately address fire risks.

Do O&M bidders need a capacity contract?

For such provision, the O&M bidder should have a capacity contract with the supplier or authorized agent of the supplier in order to carry our periodical test to the system, replace modules or other elements and/or augment the capacity of BESS in order to maintain the contracted capacity.

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.

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.

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.

What is station use energy?

Station Use: “Station use” energy refers to energy that is required for the operation of an energy generation or storage resource in order for such resource to operate. For certain types of resources the station load can be significant.
