IESO is now live with the Replacement Settlements System
Ontario ISO (IESO) has been working toward the replacement of their settlement system and as of today, May 1, 2023 it is now live. This will impact market participants by: Amendments to Online Settlement Form submissions
Amendments to Notice of Disagreement System and Process
Amendments to the Settlement Dispute and Resettlements Processes
Amendments to Settlement Charge Types and Equations
Recalculated Settlement Statements (RCSS) will be introduced
Amendments to Preliminary and Final Settlement Statements We have gathered the requirements to be able to modify our existing automated tools, processes, and downstream systems to reflect amendments to the technical specifications for charge types and data files and adjusted our Market Link processes to capture data of the new Recalculated Settlement Statement. As data comes into our system we will validate and confirm along with our client partners to ensure a seamless transition.
SPP Markets Release 2.10
SPP Markets Release 2.10 was originally contained in the Uncertainty Product development. This release includes three system changes. Changes in this release include: Enhanced intra-day reliability unit commitment Fast-start resources are essential to the reliable provision of energy. These resources typically have short startup times, low minimum run time requirements and faster than average ramp rates. These characteristics provide the needed flexibility for managing the operational challenges SPP faces. Although the need for fast-start resources could potentially decrease with the implementation of ramp market products, SPP anticipated continuing to encounter unforeseen circumstances that will require a fast-start market product/service. While SPP currently has a participation model for fast-start resources, many market participants believe the model’s compensation principles are lacking and do not adequately incent participation of fast-start resources, thus this change has been implemented. Day-ahead supply adequacy timing changes The Day-Ahead Supply Adequacy study currently is executed by 1200 Central Prevailing Time on the day prior to the Operating Day. This leads to inaccurate accounting of tags because most tags are not set until later in the day. This WRR will move the execution of the Day-Ahead Supply Adequacy study to be executed by 1700 Central Prevailing Time on the day prior to the Operating Day Partial participation entity dispatch enhancements to SPP Western Energy Imbalance Market (WEIS) Partial Participation Resources (PPRs) receive a Dispatch Instruction equal to their observed SCADA MW since they are not dispatchable in the WEIS Market. While this is appropriate for some PPRs, SPP has observed that some PPR resources will start moving towards their load and tag obligation when these obligations change. Due to the echo logic WRTBM has a 10 minute lag for this movement. This WRR will allow Balancing Authorities to communicate to SPP which PPRs should be expected to follow a schedule and which PPRs should be echoed. PPRs that are communicated to follow a schedule will be ramped towards that schedule when the schedule changes. This activation has occurred as of today, January 17, 2023.
Application Compatibility
In 2018, Microsoft started its App Assure initiative (applications will work on Windows 10, and if they do not — Microsoft engineers will help find a solution). Microsoft claims that application compatibility remains a core tenet of their planning and development process. According to Microsoft, this application compatibility promise applies to Windows 11. To double-check whether your application works as expected on Windows 11, please review the following official testing routine: Testing Guidelines . Adapt2 has ensued & approved the testing guidelines with no outstanding issues. In case you run into any issues, please feel free to contact support for further troubleshoot any issues.
