Embedded and Renewable Generation (SE-57)

​This initiative has been superseded by Renewable Integration (SE-91). For more information and to provide feedback on embedded and renewable generation please visit SE-91.

Embedded or distributed generation is usually a small scale production of power connected within the distribution network and not having direct access to the transmission network. These generators are typically located close to the electricity consumer.

In August 2005, the Ministry of Energy requested that the Ontario Power Authority (OPA) and the Ontario Energy Board (OEB) work together to address barriers to the development of small electricity generating projects using clean or renewable energy sources that are connected to the electricity distribution system in the province.

In November 2006, the OPA launched a Renewable Energy Standard Offer Program (RESOP) for the province, and will also be launching the Clean Energy Standard Offer Program (CESOP). Both programs focus on generators under 10 megawatts connected to the distribution system.

When connected to the distribution system, these smaller generators can make a significant aggregate contribution to security of supply for Ontario consumers and to achieving the Government's objectives for clean and renewable energy supply.

The scope of this initiative includes centralized forecasting, management of minimum load periods (including periods of surplus baseload generation) and development of standards

The goal of this stakeholder plan is to provide stakeholders the opportunity to give feedback to the IESO on the discussion paper and the potential market rule changes highlighted in the paper.
