An energy system prototype with a capacity of 1.2 MW and 1.2 MWh will be tested in Quebec this summer. A joint venture was formed by Hydro-Quebec and Sony Corporation to develop and test the system. It was reported that it can store an amount of electricity that is the same as the daily consumption as 23 homes in Quebec.
This number might not sound like a lot, but the effort is only a test. If it goes well, it sounds as if there will be larger systems considered or a larger number of them. It would not make any sense to go full throttle on an energy storage project without trying a small system and getting feedback about its performance first.
The prototype uses well over 500 battery modules made by Sony and they use lithium-iron phosphate technology made by Hydro-Quebec. Testing will be conducted at Hydro-Québec’s research institute in Varennes, Québec. The intention is to use the energy storage system to assist during peak loads and with renewable energy integration.
The partnership with Sony actually was announced previously. “I am confident that through our partnership with Hydro-Québec, which possesses deep knowledge of lithium-ion rechargeable batteries, we will be able to develop an optimum large-scale energy storage system to meet the demands of customers. In addition to Sony’s energy storage systems for the home and office, we will aim to expand our business using the technology produced through our joint development and contribute to the spread of sustainable electricity infrastructure,” said Yoshito Ezure, Senior General Manager of Energy Division at Sony. Sony began to mass produce 1.2kWh-class storage battery modules with olivine-type batteries in 2011.
Hydro-Quebec is a public utility that is owned by the Quebec government. It provides electricity to the whole province with about 60 hydro-power installations and employs about 21,000 workers. Almost all of the province’s electricity is generated by hydro-power. Quebec has a population of about 8 million people.
