Asset Acquisition and Integration of Scheduling and e-Tagging

Issue

The client is an industry-leading renewable energy owner and operator, actively trading, scheduling, and settling over 7,800 MW of wind, solar, and storage assets across multiple ISO/RTO markets in North America.

The client acquired a new 80 MW solar facility with a power purchase offtake agreement in the western interconnection of the United States. However, the project faced a strict deadline to achieve commercial operations and avoid penalties. The facility is located in BPA's service territory, and BPA participates in the CAISO EIM market. Despite the solar facility and associated PPA being a non-participating resource in the CAISO EIM, the client was obligated to meet CAISO EIM market rules for scheduling and settlement obligation requirements that they were unfamiliar with and had limited resources to implement correctly and on time.

Solution

Under the pressure of a tight deadline, the client engaged MidDel, emphasizing the conditions that timely delivery was non-negotiable and requiring a streamlined, efficient solution. MidDel conducted a comprehensive analysis of contracts, market tariffs, transactional objectives, and operational challenges. Using the results of the analysis, MidDel aligned CAISO EIM market rules and requirements with the client's business objectives and designed the necessary system requirements. The solution, integrated into the PowerOptix platform, fully automated the end-to-end commercial management of the solar asset, resulting in a highly accurate and efficient system while eliminating the risk of manual errors from frequent scheduling and tagging updates. Key features of the solution included:

• Automated the ingestion of BPA forecast data including day-ahead and real-time.
• Automated tag creation and submission processes utilizing the forecast data, ensuring compliance with CAISO EIM rules.
• Integration with the client's ETRM system providing seamless financial reporting.
• Integrated hourly revenue meter data from the client's PI system, enabling independent shadow settlements, invoice reconciliation, and accurate P&L reporting.

Result

The solar facility successfully went live on time while meeting all requirements, allowing the client to avoid costly penalties. Additionally, the fully automated solution delivered further benefits by increasing margins through the elimination of traditional manual activities, which often lead to errors and inefficiencies.

• Highly efficient automated processes meeting all scheduling update requirements without manual intervention.
• Risk mitigation of manual errors by eliminating data errors typically caused by having to perform frequent manual entry and scheduling updates.
• Compliance with CAISO EIM market and BPA scheduling rules, avoiding penalties.
• P&L reporting indicating transactional performance in an expedited manner compared with prior methods.

Key Takeaways

• A compliance obligation doesn't require market participation to carry full cost: a non-participating resource still owes complete CAISO EIM scheduling and settlement performance. Treating that as a systems-design problem up front — not a staffing problem later — is what makes an unfamiliar market rule survivable on a hard deadline.
• Automating the full scheduling-to-settlement chain — forecast ingestion, eTagging, and PI-based shadow settlement — creates a repeatable pattern: once the workflow runs without manual touch, compliance stops competing with margin, and the same template ports to the next asset or market.
