Energy storage project installation bidding

Why do co-located facilities have separate Energy bid curves?

Since they are modeled as separate resources , co-located facilities submit separate energy bid curves, have separate metering arrangements, submit separate outages, receive separate dispatch instructions, and may be operated by different entities.

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.

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 is a competitive energy bid?

Competitive energy bids on the charging portion of the bid curve should reflect the opportunity cost of forgoing charging at a given point in time. If a resource submits very low charging bids, the resource will be less likely to receive a charging award, and the low bid reflects a low cost of forgoing charging.

Are bid cost recovery payments real-time?

Department of Market Monitoring Californ– ia ISO June 2024 2023 Special Report on Battery Storage 24 Almost all bid cost recovery paid to batteries is in the real-time market. The main limitations on battery dispatch that lead to real-time bid cost recovery payments stem from state-of-charge constraints that limit charging and discharging.

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.
