Grid scale Energy Storage is Commercially Feasible and Cheaper than the Polish Plan
Yesterday, Gramwzielone in Poland posted an article on the first commercial grid scale energy storage project to go in operation in Germany. The Schwerin local power company Wemag is starting operations on a 5 MW magnesium ion battery storage system. The technology is from the United States, acquired by the purchase of the American company Xtreme Power. Because of its response time and its ability to make a contribution to both the top and the bottom of the energy demand curve, the supplier " Younicos ensures that energy storage with a capacity of 5 MW will provide the same stabilization of the network as a conventional power plant with a capacity of 50 MW. " This result can be expected given the studies of the cost-effectiveness of energy storage versus the use of entire power plants as "peakers" - just operating during the times of peak demand.
