The hydroelectric power plant La Grande -2-A (French Centrale La Grande -2-A ) is a storage power plant in the Canadian province of Québec. It is located in the region Jamesie on Réservoir Robert - Bourassa, about five kilometers from the town of Radisson. In the immediate vicinity of the hydroelectric power station Robert - Bourassa, the dam of the reservoir at La Grande Rivière is about six kilometers to the east of it.

The power plant is part of the James Bay hydroelectric project and has six Francis turbines. The installed capacity of generators is 2106 MW, at a height of 138.5 meters. Operators of the power plant is the Société d' énergie de la Baie James, a subsidiary of the state-owned power utility Hydro-Québec.

Construction on the power plant La Grande -2-A began in the summer of 1987 and lasted until the fall of 1992. Fully underground facility is located in a cavern, which is 223 meters long, 22 meters wide and 46 meters high. For this purpose had to be carved out 180,300 m³ of rock from the hard rock of the Canadian Shield. The official opening of the plant took place on 1 October 1991 with the commissioning of the first turbine.
