Expedited System Impact Assessment Process

A full impact assessment may not be necessary when connection proposals do not represent major system changes or would not have a major impact on the reliability of the integrated power system. In this case, an expedited SIA (which does not require a formal study), is conducted.

Each box below outlines the steps involved in the expedited SIA process. The guidelines for determining if an expedited SIA is required are listed here.

The application forms and submission guidelines for the expedited SIA are the same as the standard SIA depending on whether you represent:

• Generation Facilities
• Transmission Facilities
• Load Facilities

The IESO determines if an expedited SIA is appropriate within five business days following receipt of the application. The IESO also notifies the applicable transmitter(s) of the SIA application.

The connection applicant is not required to submit a deposit but is required to agree to pay for the total costs and expenses associated with all of their expedited SIAs by signing a Cost Recovery agreement. The IESO negotiates this agreement with each connection applicant before commencing the first expedited SIA. This agreement also covers all subsequent expedited SIAs initiated by the connection applicant.

An expedited SIA report is then issued by the IESO detailing the various requirements and criteria of the connection proposal, as well as a summary of the various study results.

This report is then published on the IESO web site which contains a list of all transmission, load, generation and ancillary services connection proposals that meet the requirements described in section 9.2 of Market Manual 2.10.
