The best opportunity to "get more green" into Ontario's electricity
supply mix is to allow clean, sustainable sources of power to replace
ageing nuclear reactors when they reach the end of their operational
The graph below illustrates the gap which opens up as Pickering B
and Bruce B (in red and orange) come offline beginning in 2013 and
presents how additional clean options can fill this gap.
According to the Ontario Power Authority (OPA), the Ontario government must decide early in 2009
whether to rebuild or replace the Pickering B nuclear station scheduled
to come offline in 2013. A similar decision about the Bruce B nuclear
station must be made within the mandate of this government as well.
However, by framing these two decisions as "either rebuild or replace"
nuclear stations, the OPA has failed to consider the option of
expanding renewable energy beyond the minimum in the supply mix
directive. There is a better green energy choice: Replace aged nuclear reactors with quick-to-deploy green energy sources and conservation.
Instead, the OPA has given the government an unpalatable choice:
rebuild old reactors at high cost and high risk or build new nuclear
plants by 2020. Both options increase fossil generation until reactors
are refurbished or built, resulting in the risk of higher greenhouse
