Comment Comment by hn_throwaway_99 It's a good question, but when discussing grid energy storage, there are 2 important things:1. How much power output the storage can replace (i.e. discharge capacity) . The appropriate unit for that is watts (or megawatts, etc.)2. How long can it do it for (i.e storage capacity) - as you point out, the appropriate metric for that is megawatt-hours. parent hn_throwaway_99 1 year ago
