Wind Energy Update has an article on Canadian pumped hydro energy storage storing American wind power - American wind to be stored in Canada.
A pair of utilities, Minnesota Power and Manitoba Hydro, have inked a Renewable Optimisation Agreement (ROA) under which electricity from excess wind produced in North Dakota can be stored in Manitoba’s hydro reservoir when loads and prices are low, with the potential for selling that power back onto the huge United States Midwest Independent Transmission System Operator (MISO) market at times when needs are high.The deal involves the pair building a new 400 mile 500 kV transmission line, with a capacity of 750 megawatts, connecting northeastern Minnesota with Winnipeg, at a cost of $1bn split between the two utilities. ...
The province lies at the centre of a 400,000 square mile watershed that drains from the Rocky Mountains to the west and Lake Superior to the east. The Nelson River drains north to Hudson Bay with an average flow at the sea of 115,000 cubic feet per second - eight times that of the Colorado River.
Manitoba's 1,000 feet of hydro-electric potential remains only half developed and two new hydro projects with associated storage planned for the Nelson River has created the opportunity for further interconnecting the Manitoba battery to MISO.
