Proposed additional regional capacity.

Hydro One’s proposed double-circuit 230 kV line runs between Clarington and Dobbin transformer stations. Its June 12, 2026 announcement reports a leave-to-construct application and an anticipated 2029 in-service date.[33, 34]

Hydro One’s large-customer connection pathway covers transformation or nameplate capacity of at least 2 MVA. The published process includes assessment, design and estimate, construction and connection.[66]

Solar mapping.

The City of Peterborough publishes a solar-potential map developed with Fleming College.[36]

Wind generation.

Wind supplied 8.7% of Ontario’s transmission-connected generation in 2025. Ontario publishes renewable-energy approval information for wind and solar projects.[40, 43]

Generation and power contracts.

Hydro One publishes a generation connection process. IESO publishes a corporate power-purchase agreement framework for eligible Industrial Conservation Initiative participants.[37, 38]

Ontario’s generation mix.

For 2025 transmission-connected generation, IESO reports 48.2% nuclear, 23.1% hydro, 8.7% wind and 19.3% gas/oil. These figures exclude embedded generation.[43]

Ontario’s data-centre framework.

Environmental Registry notice 026-0853, posted August 13, 2026, proposes a framework covering economic development, digital sovereignty, community benefits and a separate electricity-rate class for new large data centres. The registry lists the notice at the proposal stage.[35]
