23 Price differences between MPM and IFM

24 Price difference between MPM and IFM on June 21, 2017 was over $200/MWh at peak hour July 18. CAISO discussed high IFM prices observed in June during the heat wave July 18. SCE asked during the MPPF meeting about the price difference between MPM and IFM of June 21 August 3. ISO provided some general explanation in the market update call about how this could happen as it continues to investigate September 25. DMM covered this topic in its Q2 report November 1. During all this time the ISO continue to investigate and eventually found the reason for these price differences Page 24 Last updated: December 18, 2017

25 The difference between MPM and IFM was driven by the different treatment of derates Issue introduced in August 2016 with implementation of MPM enhancements to real-time markets and was fixed in July 2017 Based on root cause, it is expected only day-ahead has been impacted The derates were missed in the MPM pass Energy schedule was below derate Energy + Reg-up + Spin + Non-spin may exceed derate The correct derates were used in dynamic path assessment, and IFM Page 25 Last updated: December 18, 2017

26 Analysis on the price difference between MPM and IFM took different paths Preliminary ISO s investigation pointed towards a potential issue in MPM and that the IFM solution was correct. Although Q2 DMM s report provided estimates of $25 million associated with this difference on June 21, deeper ISO s analysis indicates for this day there was no impact on the binding IFM prices. Running MPM with the right consideration of derates results generally in same prices as those cleared in the original IFM solution Uncompetitive constraints binding and set of mitigated units remain largely the same with and without the derates included Final finding: Prices observed in IFM were correct given market conditions, but what are the implications of MPM missing derates? Page 26 Last updated: December 18, 2017

27 Potential impacts to the market The derates will only affect market power mitigation, but NOT IFM market clearing itself, because IFM used the correct derates The derates may lead to a different SMEC in MPM with respect to IFM which may not necessary bear an impact on IFM The missing derates may potentially relieve congestion in the MPM run, and cause some constraints bypassing dynamic path assessment a lower shadow price on non-competitive constraint The derates do NOT affect Residual Supplier Index

88 Developer Site Launch René Dupré Manager, Corporate Systems Page 88 Last updated: December 18, 2017

89 Our Observations Developers are opening tickets for basic issues: How to do I get access? How to make an API call? My API call yields no results and I don t understand why? New API releases / changes may not be obvious. Releases can span applications, adding complexity to finding updated information. has little audience segmentation to support developers. There is an increase in new developers, and they don t know where to start. This all results in CIDI tickets and delayed developer support. Page 89 Last updated: December 18, 2017

90 Improvement Launching New Website Developer information will no longer be buried in ISO will launch a new site which consolidates information and organizes it by application. CAISO.COM Participate Stay Informed Planning Market & Operations Rules Developer Info Getting Started developer.caiso.com FAQs Troubleshooting Ports & IPs URLs Glossary Acceptable Use Discussion Board WSDLs XSDs Page 90 Last updated: December 18, 2017

91 Login Page Page 91 Last updated: December 18, 2017

92 Registration Required Unfortunately, the Internet presents security challenges which is forcing the ISO to rethink its policy of publically posting all its API information. Thus, developers need to register so we know who is accessing technical data and to enable a vetting process. Existing market participants are automatically approved access and will not experience any registration delays. Non-participants will be contacted by our Information Security department to determine need and use. Simple user id and password model, no certificate. Page 92 Last updated: December 18, 2017

93 Site Contents API URLs & IP Addresses by environment. Service artifacts with release identification. Ability to download XMLs into developer tools. Links to documentation and release notes. Acceptable Use Policies Frequently Asked Questions Troubleshooting tips Community Discussion Board Glossary Application Outage Schedule Page 93 Last updated: December 18, 2017

94 Additional Details Much of the information is sorted by application rather than release. The site is intended to be dynamic so that new FAQs can quickly be conveyed to developers. A section will be dedicated to connectivity setup to help those struggling with access issues. Content curation is time consuming so expect that this will be a 1.0 product to deliver value immediately and will improve over time. Soft launch in late December with active promotion in January. Page 94 Last updated: December 18, 2017

95 Future Looking Future documentation may be reworked for better site integration. The Systems Integration Discussion Board in the Market Participant Portal will be ported to the new site. We will explore adding sample code and other features to help developers get to running code more quickly. After launch we will be adding a feedback link to help guide improvements.

103 2017 Deactivation of TLS 1.0 & 1.1 Info Summary Details/Date The California ISO will be deactivating Transport Layer Security (TLS) 1.0 and 1.1 in the market and performance (MAP) stage environment on date TBD 2017, and in the production environment on date TBD (based on MAP stage). Deactivating these older TLS protocol versions aligns with industry best practices for security and data integrity. It is necessary for market participants to enable TLS 1.2 as soon as possible in browsers and APIs. The ISO will deactivating TLS 1.0 and 1.1 in the MAP stage environment on date TBD 2017, and in the production environment on date (TBD based on MAP stage), and only TLS 1.2 will remain enabled. Deactivating these older TLS protocol versions aligns with industry best practices for security and data integrity. Details It is necessary for market participants to enable TLS 1.2 in browsers and application programming interfaces (APIs) as soon as possible in order to continue to access the MAP stage environment from date TBD onwards, and to continue to access the production environment from date TBD (based on MAP stage) onwards. Market participants can enable TLS 1.2 now as the MAP stage and production environments currently allow TLS 1.2. Note: it isn t necessary for market participants to manually disable TLS 1.0 and 1.1 in browsers and APIs because the TLS handshake will negotiate the highest mutually available version. Once TLS 1.0 and 1.1 are deactivated in the MAP stage environment, the ISO encourages market participants to confirm successful connectivity to the MAP stage portal, portal application's user interfaces (browser UIs) and APIs prior to the production environment deactivation on date TBD (based on MAP stage). Note: After TLS 1.0 and 1.1 are deactivated, market participants who cannot connect due to a version issue may receive errors depending on how they are connecting. Errors will likely include verbiage such as "wrong version", "unsupported negotiation", or "failed handshake". Milestone Type The Systems Milestone Access Name Information for Market Participants document contains Dates the information to access the MAP Status MAP-Stage stage and production environments. This document is available on the ISO website at Disable TLS 1.0 & 1.1 in MAP-Stage TBD Participants.pdf.
