Ontario's 2005 and projected energy demand

Ontario plans to convert some of the coal burning units to produce 2 terrawatt hours (TWh) annually from biomass

Ontario energy consumption(2005)

These figures are from different sources and use different base years but they give an approximate idea of how much energy Ontario requires.

Energy type Energy (PetaJoules*) Energy (MWh*)
Mining & manufacturing - 37.1% 1,031 286,391,180
Transportation - 29.7% 826 229,446,280
Residential - 16.8% 467 129,723,260
Commercial and institutional - 13.8% 384 106,667,520
Agriculture - 2.5% 70 19,444,600
Total secondary energy 2,780 772,228,400

*A PetaJoule (PJ) is 1015 joules or 277.78 ×106 kWh (277,780 MWh)

772,228,400 MWh would require  88,154 MW assuming that the load is spread evenly over 365 days and 24 hours (which is not the case but should be possible with advanced storage devices including battery electric vehicles )




NERC Projections

The North American Reliability Corporation (NERC) predicts that electricity demand will fall by an average of 0.2 percent (summer peak) and 0.7 percent (winter peak) per year until 2016 http://www.nerc.com/files/LTRA2007.pdf (PDF)(p.23)

NERC's estimate for 2016 is 25,066 MW (summer) and 22,540 MW (winter)

IPSP Projections

IPSP projections are that by 2023 Ontario will require about 30,000 MW (our estimate)

OPA Projections

Ontario's energy output by fuel type (2010)Ontario electricity demand is around 22,500 MW and OPA has projected that it will grow to 40,000 MW by 2025. However, if more agressive conversion to electricity is considered the projection is approximately 175,000 MW

From http://www.mei.gov.on.ca/en/pdf/MEI_LTEP_en.pdf (p. 14)

High growth (orange), or aggressive electrification, assumes that there is a significant increase in electric transportation — both public and private. It assumes that there is aggressive North American greenhouse gas regulation, faster population growth than the low growth scenario, significant industrial change and that by 2030 about 12 per cent of vehicles on the road are electric.
