EDAC Implementation
Requirements, Changes and Training
Technical Changes Impacting All Resources
Workspace (Bid/Offer/Schedule) Application Moving Into IESO Portal
To support changes to Day-Ahead Commitment Process (DACP) and the decommissioning of PKI digital certificates, the IESO will be transitioning the Energy Market Workspace (bid/offer/schedule application) from the Market Participant Interface (MPI) to the IESO Portal on October 12, 2011.
The IESO will provide Portal access to the community for all users who currently have digital certificates. For those without a digital certificate, a formal access request using Form 1276 should be submitted.
Market participants who connect to the Workspace application via an API and wish to submit 3-part offers under the EDAC Process, must upgrade to IESO Developer’s Kit (IDK) 3.3; register with the IESO to submit 3-part offers; and provide their IP address to the IESO for authentication (Form 1276). The IESO will provide a username/password for authentication, instead of using a digital certificate.
For those market participants who connect to the Workspace application via API but do not wish to submit 3-part offers, the Workspace application within MPI will continue to be available as it currently is accessed (IDK 3.2 with digital certificate) until December 31. After that date, digital certificates will be decommissioned (more information on the PKI digital certificate decommissioning project). The IESO encourages market participants to transition to IDK 3.3 as soon as possible.
