The Ontario government pocketed more than $22 million from exporting electricity in January.
Power went out on the transmission grid to customers in Manitoba, Quebec, New York, Michigan and Minnesota.
The net export revenues are based on revenues of $28.8 million, minus imports of $6.7 million, said the Ministry of Energy in a Feb. 16 release.
Since 2006, the government has made $1.8 billion from electricity exports.
