• Ontario Green Energy Act (GEA) – FIT and MicroFIT programs
Drivers of Change in Ontario
“Approximately 8,000 MW of wind energy projects have submitted applications for
FIT contracts. At this time, 2,500 MW of capacity will be able to connect to the grid,
but transmission upgrades are planned to allow the connection of significantly more
capacity over the next few years.”
