Connection Assessments and Approvals (CAA)

Introduction

In accordance with the Market Rules, Chapter 4, Section 6, anyone planning to construct a new or modified connection to the IESO-controlled grid is required to apply to the IESO and complete the Connection Assessment and Approval (CAA) process.  A new or modified connection to the IESO-controlled grid includes:

  • the connection of a new or modified generation facility to the IESO-controlled grid;
  • the connection of a new or modified embedded generation facility greater than 10 MW;
  • the connection of a new or modified transmission facility;
  • the connection of a new or modified load facility or a one time addition of load greater than 10 MW; and
  • the connection of a new or modified ancillary services facility.

Detailed information of the CAA process is available in Market Manual 2.10 - Connection Assessment and Approval.

The Connection Assessment and Approval process allows the IESO to assess the impact of new or modified connections on the reliability of the integrated power system. A connection applicant does not have to be a Market Participant in order to apply for Connection Assessment and Approval; however, the required participant authorization and facility registration processes must be completed prior to participation in the IESO-administered markets.


Assessment and Approval

Obtaining an Assessment provides an overview of the connection process, from submitting an application through to gaining approval. It includes the relevant forms and procedures. 

Feed-in Tariff (FIT) - Developers of renewable generating facilities that are interested in the FIT program are advised not to apply for System Impact Assessment in advance of executing a FIT Contract. Unless an SIA application was made prior to March 14, 2009, applying for such an assessment, in advance of the execution of the FIT contract with the OPA could result in the project's inability to participate in the FIT program.


Each project list contains status information for assessments and links to completed SIA reports.
