How do companies connect to the IESO-controlled grid?
Any company planning to construct a new or modified connection to the IESO-controlled grid must apply to the IESO for inclusion in the Connection Assessment and Approval (CAA) process. This process allows the IESO to assess the impact of new or modified connections on the reliability of the integrated power system. In terms of physical facilities, we differentiate between three types of connections: • Directly Connected Market Participant are Participants whose facility is connected directly to the IESO-controlled grid. The IESO-controlled grid controls all Ontario transmission facilities equal to or greater than 50kV. • Embedded Market Participants are Participants whose facility is connected to a distribution system and not the IESO-controlled grid. • To connect to the IESO-controlled grid, an hourly interval meter is required. An interval meter accurately measures the amount of electricity used over an interval as short as five minutes and communicates this information to the IESO o
