A North American consortium will build a set of multi-utility microgrid projects to demonstrate how microgrids can help integrate renewables with advanced software and save money. Utility participants in the project—Emera Maine (formerly Bangor Hydro),Nova Scotia Power and Toronto Hydro will team up with Opus One Solutions, Advanced Microgrid Solutions (AMS),Smarter Grid Solutions and the Center for Urban Energy at Ryerson University to demonstrate microgrid capabilities at projects both in Maine and Eastern Canada. These include delivery of virtual resources—the expertise of team member AMS—as well as a microgrid’s ability to provide feeder load relief, volt/VAR optimization and conservation voltage reduction. Emera Maine will offer an example of microgrids as a “non-wires alternative” that can serve in place of substations or other infrastructure. Emera said the project will pay for itself, with no subsidy from utility ratepayers. The microgrid will also include a Level 2 electric vehicle charging station and an advanced microgrid controller, with a battery supplied by Tesla, Microgrid Knowledge reported.
Nova Scotia Power will build a feeder-based microgrid with wind power and both grid-scale and residential energy storage. Toronto Hydro’s project will feature distributed energy resources management. Ontario-based Opus One Solutions, a software company, is leading the international project, which also will demonstrate the ability of microgrids to transact in regional wholesale markets.
