Beginning November 1, 2011, many wind and solar PV generators will be required to submit real-time meteorological and output data to the IESO.

The market rule amendment is part of IESO plans for renewable integration. As part of this integration, the IESO is seeking to implement centralized forecasting. Instead of providing energy forecasts, renewable facilities will be required to submit real-time, site specific data ("dynamic data") to the IESO that will be used to produce variable generation forecasts provided by a third-party.

The requirements will apply to all wind and solar facilities connected to the IESO-controlled grid in addition to embedded non-market participants with an installed capacity over 5MW.
