Sponsored by Businesswire

Power Costs, Inc. (PCI) is pleased to announce the successful April 1 transition of Turlock Irrigation District (TID) to the CAISO-operated Western Energy Imbalance Market (WEIM). With its go-live, TID becomes the eighth PCI client (after NVE, APS, PSE, PGE, PNM, LADWP, and SMUD) to successfully begin full participation in the WEIM.

TID leveraged PCI’s secure, integrated, web-based cloud platform to manage WEIM business requirements for its Balancing Authority (B.A.) and trading operations. It selected PCI after a rigorous competitive process that, among many priorities, included forging a long-term partnership with an experienced, reliable software supplier that could help maximize the opportunities and benefits of joining the new market.

Some of the functionality available in PCI’s CAISO WEIM Platform for hydro-heavy participant portfolios includes:

  • Advanced bidding strategies to assist in managing complex, highly constrained hydro resources
  • Advanced Flex Ramp Forecasting supports balance-of-day and next-day trading decisions
  • Custom user homepages and workflow interfaces for specific groups (e.g., PRSC, EESC front office, etc.)

TID’s Assistant General Manager of Power Supply Dan Severson stated, “WEIM participation is a significant achievement for us. PCI’s deep WEIM experience, the diligent planning and execution by our staff, as well as the close collaboration between our teams were all critical elements in a seamless transition to go-live.”

“The partnership between PCI and TID has been exemplary, and we are proud of the accomplishment of delivering another successful WEIM solution on-time and within budget,” said PCI Vice President Jason Hebert.

PCI’s CAISO WEIM Platform is a complete solution that provides benefits to market participants, including Transmission Service Providers (TSPs), EIM Entity Scheduling Coordinators (EESCs), Participating Resource Scheduling Coordinators (PRSCs), and Sub-entity Scheduling Coordinators (SESCs).
