ADEQUACY REPORTING UPDATE

Mark Gojmerac, IESO

March 10, 2016

• Changes to Market Manual 7.2

• Changes to the Adequacy Report

• Update on RSS feeds for Advisory Notices

• Proposed Parallel Run for Go Live

• Updated Implementation Schedule

• Next Steps

Agenda

2

• Separation of SSRs and SAAs into the new reports: Adequacy, Transmission Limits, Advisory Notices and Zonal Demands

• New submission method for market participants with energy limited resources (using Online IESO)

• Threshold criteria for publishing Advisory Notices for Major Changes replaced with increased publication of information.

• Examples provided when Advisory Notices for Major Changes or High Risk would occasionally be published.

• Revised list of interface limits to report (discussed later)

Changes to Market Manual 7.2: Overview

3

• Advisory Notices that will normally be published:

• Advisory notices that may occasionally be published:

Changes to Market Manual 7.2 (cont’d)

4

Type Scenario System Advisory • Surplus Baseload Generation

• Shortfalls in Operating Reserve • Shortfalls in or changes to Ancillary Services

Emergency Advisory Emergency Operating State Market Suspension/Resumption

Suspension or resumption of all or part of the market

Type Scenario

System Advisory Major Change (e.g. loss of substation, entire interface)

Emergency Advisory High Risk Operating State (e.g. extreme weather)

• List of internal and external interfaces for which limit deviations are published

• Updated to reflect nomenclature changes

• IESO proposes reducing the number of internal limits to report: – Consistency with 18 Month Outlook reporting – Not impactful with control actions available for limit

improvement – Some either redundant or no longer applicable

TEC Not impactful / control actions available

• Last version (posted March 2015) addressed the following stakeholder comments: – Inclusion of Peak and Average Demand forecasts – Inclusion of Embedded Wind and Solar forecasts – Consistent format and content across all reporting

timeframes (i.e. Days 0 to 34) – East/West zonal demand forecasts will continue to be

published, through a separate report

Adequacy Report Recap

• Revised version now posted on the SE-AR page and includes the following changes:

Adequacy Report Changes

9

Added (rationale) Removed (rationale)

Capacity Imports and Exports (capacity sharing agreement with Quebec)

Wind and Solar ‘Offers’ (only forecasts available)

Bottled Capacity (increased transparency)

Dispatchable Load ‘Outages’ (currently no mechanism to calculate)

Demand Response Bid, Schedule and Curtailment (inclusion of DR Auction)

Total Internal Resource ‘Bids’ (captured under Dispatchable Load)

Offered Capacity Excess/Shortfall (to differentiate from Installed Capacity Excess/Shortfall)

• 3 feeds available via IESO website: – Day 0 Advisory Notices – Day 1 to 34 Advisory Notices – Emergency Advisory Notices

• Feeds include the following:

– Version (unique feed ID with version no.) – Issue date (i.e. original date/time) & Update date – Start and End date (i.e. duration of the notice) – Advisory Type (e.g. System, Market Suspension etc.) – Short and Long Descriptions (e.g. Surplus Baseload

Generation is forecasted)

RSS Feeds for Advisory Notices

10

• Approx. 1 min delay between IESO issuance and site publication

• Sample files will be made available by March 30th on the IESO Report Listing page

RSS Feeds for Advisory Notices (cont’d)

11

• 24 hours of parallel operation between old and new reporting systems proposed

• Maintaining updated information in the old reports will be on a best effort basis

Proposed Parallel Run for Go Live
