7 minutes, 42 seconds Read

ZEMA, enterprise data management solution for commodities and energy markets, can help control your data from collection to validation to integration and create a seamless environment throughout your organization.

As the only independent grid operator in the western United States, the Californian ISO grants equal access to 26,000 circuit miles of transmission lines and coordinates competing and diverse energy resources into the grid where it is distributed to consumers. It also operates a competitive wholesale power market designed to promote a broad range of resources at lower prices. Every five minutes, the ISO forecasts electrical demand and dispatches the lowest cost generator to meet demand while ensuring enough transmission capacity for delivery of power. As the nerve center for the power grid, the ISO matches buyers and sellers of electricity, facilitating over 28,000 market transactions every day to ensure enough power is on hand to meet demand.

The California Independent System Operator (CAISO) operates a competitive wholesale electricity market and manages the reliability of its transmission grid. CAISO provides open access to the transmission and performs long-term planning. In managing the grid, CAISO centrally dispatches generation and coordinates the movement of wholesale electricity in California and a portion of Nevada. CAISOs markets include energy (day-ahead and real-time), ancillary services, and congestion revenue rights. CAISO also operates an Energy Imbalance Market (EIM), which currently includes PacifiCorp’s two balancing authority areas.

CAISO released the Open Access Same-time Information System (OASIS) website to provide market participants with a user-friendly way to access pricing information, as well as other related system reports. For many market participants the most critical reports are the real-time OASIS LMP results which contain the pricing data for nodes in the system. Each node consists of 4 report intervals: RTM, HASP, RTPD and DAM. Report interval refers to the length of a request. The report interval for RTM (Real-Time Market Interval LMP) is one hour and has a data resolution of five minutes. The report then provides twelve data points for each LMP component. Likewise, the DAM (Day-Ahead Market) report contains twenty-four data points, one for each hourly interval in a day.

During the Fall release 2016 initiatives market simulations, participants will be able to observe market results in the same applications that are available in Production: OASIS, CMRI, and so on. Participants can input data into the ISO Bid-to-bill using all systems available in Production: OMAR, SIBR, ADS, Web OMS etcetera. In the Fall Release 2016 initiatives, market simulations will be conducted in the MAP Stage environment. Participants will need to obtain access to this environment if they do not already have access. The ISO envisions participants may wish to access Master File (MF), Market Participant Portal (MPP), Outage Management System (WebOMS), Scheduling Infrastructure and Business Rules (SIBR), CAISO Market Results Interface (CMRI), Automated Dispatch System (ADS), and Market Results Interface Settlements(MRIS).

In the Fall 2016 Release, the California ISO (CAISO) will deploy numerous system changes resulting from various projects and other efforts. Some of the key enhancements made with 2016 fall release are explained below:

  • The OMAR Online Replacement effort provides the mechanism for incoming EIM entities as well as all current OMAR customers to develop coding interfaces against the Application Programming Interface (which does not exist within the current OMAR).
  • PIRP Application Decommissioning will provide enhancements to the Automatic Load Forecasting System (ALFS) tools to provide more accurate and user friendly functionality. These enhancements will also make available Commercial Operation for Market (COM) dates and MW values to software systems and business processes. Customer Market Results Interface (CMRI) reports which will replace decommissioned PIRP reports, providing market participants and the public with aggregated hourly average of market schedules, forecasts, and actual production for wind/solar VERs or VERs plus net virtual supplies.
  • The flexible ramping product is a key market design enhancement to ensure sufficient upward and downward flexible capacity is available and efficiently dispatched in the ISO real-time market. This design will improve the management of ramping capacity in the real-time market. The Fall 2016 release Implementation of Flexible Ramping Product will allow the ISO to efficiently and economically achieve the environmental policy goals across the West
