New York utility Con Edison is testing a commercial business model where it calls the shots and the customer simply hosts the battery. This model simplifies the commercial energy storage sales process by pitching a lease for space in areas where the utility needs help, rather than the typical bill management use case, where batteries lower the power bill by predicting and neutralizing a customer's demand spikes. Distributed energy company GI Energy (now part of Shell's cleantech empire) is developing four 1-megawatt/1-megawatt-hour systems to test whether this model works.
