Utilities across Canada are making large investments in the maintenance of ageing infrastructure and in the construction of new power lines and substations to connect new generation sources to the bulk power system. For instance, in 2009 Ontario spent $2.3 billion on a series of transmission projects aimed at connecting new renewable capacity fostered by the Green Energy Act. In Alberta, the AESO recommended in 2008 the construction of a $1.83 billion, 240 kV looped system in the southern part of the province to integrate up to 2,700 MW of new wind generation. In Quebec, Hydro-Québec TransÉnergie filed a $1.47 billion investment plan to connect 2,000 MW of new wind generation scheduled to come on-stream between 2011 and 2015.
