Renewable Performance Report

• A new monthly report with renewable and operational

metrics will be available on www.caiso.com

• Similar in style to the new Today’s Outlook
• Highlights include:

– HTML based with Javascript charts – Ability to hover on charts, zoom, deselect categories – Ability to download the data for a given chart – Includes reliability data / metrics (CPS1 and RBC)

• A new report will be available on the 15th of each month

criteria for going live

• PGE went live on October 1, 2017
• Transitional period provisions in place for first 6 months
• Smooth transition into EIM operations

Price differences between MPM and IFM

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

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

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

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

• n 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

Developer Site Launch

René Dupré Manager, Corporate Systems

Page 88 Last updated: December 18, 2017

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.

• WWW.CAISO.COM 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

Improvement – Launching New Website

• Developer information will no longer be buried in

WWW.CAISO.COM.

• ISO will launch a new site which consolidates information

and organizes it by application.

Registration Required

• Unfortunately, the Internet presents security challenges which is

forcing the ISO to rethink its policy of publically posting all its API information.

Page 92 Last updated: December 18, 2017

• 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.

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

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

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.

Milestone Type Milestone Name Dates Status

MAP-Stage Disable TLS 1.0 & 1.1 in MAP-Stage TBD Production Disabling Disable TLS 1.0 & 1.1 in Production TBD based on MAP stage

Info Details/Date

Summary 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.

Details 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. 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". The Systems Access Information for Market Participants document contains the information to access the MAP stage and production environments. This document is available on the ISO website at http://www.caiso.com/Documents/SystemAccessInformation_Market Participants.pdf.
