IESO's 2016-2020 Strategic Plan

The IESO's 2016-2020 Strategic Plan describes some of the opportunities and challenges the organization is expected to face over the next five years and charts a clear course forward. The plan considers a range of environmental factors that are expected to affect the organization, including climate change, emerging technologies, operability, consumer engagement and cybersecurity, among others. Four overarching goals have been set for the IESO:

  • Deliver superior reliability performance in a changing environment,
  • Drive to a more efficient and sustainable marketplace,
  • Be recognized as a trusted advisor, informed by engagement, and
  • Invest in our people and processes to meet the needs of the sector.

Business Plan and Request to Reduce IESO Fee Filed with the OEB

The IESO is requesting a nine percent reduction in its usage fee in its revenue requirement submission filed with the Ontario Energy Board on January 19. The 2016-2018 Business Plan, which reflects the annual savings of $5 million from merging the IESO with the Ontario Power Authority, formed part of the submission.

Further efforts outlined in the plan expect to achieve savings of more than $10 million by 2018, allowing the IESO to request a lower fee. The IESO is seeking approval of a proposed 2016 revenue requirement of $181.1 million to be recovered through a usage fee of $1.13 per MWh, effective January 1, 2016. This fee represents a nine percent reduction compared to the combined current IESO usage fee of $0.803/MWh and the current Ontario Power Authority usage fee of $0.439/MWh. The current fees were made interim effective January 1, 2016.

The IESO's three strategic themes – providing public value, building corporate resilience, and respecting and valuing our stakeholders – provided the context for its business planning. The plan outlines the IESO's focus and deliverables over the business planning period in each of its business units. Engagement initiatives and the IESO's Stakeholder Advisory Committee will continue to play an important role in providing input into the IESO's decision-making.
