Grids & Integration

Utility Nova Scotia Power wanted to impose a monthly charge on net-metered solar system owners which the Canadian Renewable Energy Association said could have doubled the payback period for household and commercial arrays.

A pair of researchers from UC San Diego has proposed to precompute certain data when the grid is flooded with solar or wind power, and then store it on servers for later use.

Queensland company eleXsys Energy has secured more than AUD450,000 to help finance a trial of next-generation technology designed to manage grid stability in low voltage areas, potentially allowing for an increase in the amount of distributed energy resources, including rooftop solar, that can be connected to the grid.

TransAlta has planned to start construction on the storage facility in March 2023 and to complete it within nine months. The 180 MW battery facility is designed to be charged by the existing Ghost Hydroelectric facility when demand is lower.

The recharging station will operate 24 hours a day and in a flexible format, which will allow fleets of electric buses, last-mile distribution vehicles, trucks, taxis and private electric cars to be supplied through fast charging points.

New research from the U.K. shows the increasing competitiveness of long-distance hydrogen interconnectors over the next three decades. Compared to high-voltage electricity cables, hydrogen interconnectors may soon achieve a much lower levelized cost of storage and their ability to further reduce the final LCOE will depend on how much electrolyzer costs will reduce over the years.

The first 20MW/20MWh battery energy storage system in the 470MW/470MWh portfolio Fluence is deploying for Filipino conglomerate San Miguel Corp has started serving the island nation’s electricity network.

Toronto-based developer Amp Energy has had the green light to install two 400MW batteries in central Scotland which have been touted as the largest grid-connected battery storage facilities in Europe. The projects will deploy grid-forming inverters and be coupled with two synchronous condensers.

The spark of renewables in the MENA region has increased the need for new interconnectors. Big projects with high capacities are being planned across borders to raise electricity exchanges across the region, reviving the dream of a MENA integrated electricity grid.

Electric transmission company Elia Group noted a bigger slice of the generation mix occupied by nuclear last year, just hours after a London-based consultant said the nation was on track to switch off its reactors before 2026.
