Avista Corporation Successfully Enters CAISO Western Energy Imbalance Market (WEIM) Using PCI’s Enterprise Cloud Platform
April 27, 2022 – Avista Corporation (Avista) successfully joined the Western Energy Imbalance Market (WEIM) operated by the California Independent System Operator (CAISO) by leveraging the PCI Enterprise Cloud Platform for its optimized participation in the WEIM. With its go-live, Avista becomes the 11th client of Power Costs, Inc., to successfully begin full participation in the WEIM.
PCI and Avista worked together for two years to deploy a fully integrated cloud-based platform to support the following functions for both Avista Merchant Group and Balancing Authority:
- PRSC Bidding and Scheduling to automate merchant bidding functions
- EESC Scheduling to support BA scheduling functions
- Energy Accounting to validate meter data
- Generation Outage Management to manage generation outages
- Transmission Outage Management to manage transmission outages
- Enterprise Analytics and Reporting to create custom reports
PCI is also providing Avista with turnkey, around-the-clock support for mission-critical operations.
“The WEIM go-live implementation went very smoothly,” said James Dykes, the Avista EIM Technology Program Manager and EIM Technology Operations Manager. “PCI’s extensive experience in working with multiple WEIM participants, technology platform with in-depth coverage, and implementation expertise were critical success factors for an on-time and on-budget delivery.”
PCI Sr. VP Khai Le added: “Working with the Avista team to achieve a seamless go-live is a testimonial for PCI’s continued success in supporting a majority of the WEIM participants.”
PCI’s CAISO WEIM Platform is a complete solution that provides benefits for WEIM players, including Transmission Service Providers (TSPs), EIM Entity Scheduling Coordinators (EESCs), and Participating Resource Scheduling Coordinators (PRSCs).
