Hydro-Québec, Canada’s biggest electricity producer dived into the energy storage market with the launch of EVLO Energy Storage Inc. (EVLO), a subsidiary that will design, sell, and operate safe, efficient and sustainable energy storage systems.
These storage systems are intended mainly for power producers, transmission providers and distributors, as well as the commercial and industrial markets for medium- and large-scale storage.
Their modular design means that they can be scaled to meet a wide variety of needs.
EVLO systems also include power control and energy management software.
“Energy storage will play a crucial role in the energy transition,” said Hydro-Québec President and CEO Sophie Brochu. “We firmly believe that the know-how Québec has acquired with regard to batteries will help develop solar and wind power. Our products will also have useful applications in existing power grids, such as in managing consumption peaks.”
The company in a statement said EVLO technology is the result of more than 40 years of R&D on battery materials by Hydro-Québec, which has more than 800 patents in this field. EVLO storage systems have been tested in actual operating conditions on Hydro-Québec’s grid, not only for peak shaving at Hemmingford substation in the Montérégie region, but also in the Quaqtaq off-grid system in northern Québec, where they were subjected to extreme weather. The technology is also being used in the Lac- Mégantic microgrid and in Hydro-Québec’s solar farm in La Prairie.
The company touts that it’s lithium iron phosphate (LFP) batteries are much safer than conventional lithium-ion batteries, since their molecular structure provides intrinsic protection against thermal runaway. They also have a smaller environmental footprint, not just because they are made from naturally abundant, nontoxic materials, but also because they can be recycled using a process that allows 99% of the active materials to be recovered and reused. Moreover, EVLO systems do not contain any cobalt or rare earth elements.
EVLO also announced that it has signed a memorandum of understanding with Innergex énergie renouvelable inc. to participate in the Tonnerre projet, in France. This project involves the installation of a 9-megawatthour (MWh) storage system in the transmission system operated by France’s national transmission provider, RTE, under a long-term agreement between RTE and Innergex, to help meet France’s capacity requirements. The system is slated for commissioning in 2021.
“Tonnerre is Innergex’s first stand-alone battery project, and we’re happy to be partnering with Hydro-Québec to showcase Québec expertise internationally,” said Michel Letellier, Innergex’s President and CEO. “Storage plays a key role in the global development of renewable energy options and is a growth driver for Innergex.”
