As someone who doesn't work in power, labeling an energy storage's capacity in megawatts is a bit confusing. What does it mean when a pumped water storage facility has a capacity of 1400 MW? Does this literally mean that the turbines can physically provide 1400 MW when active? Shouldn't the unit of measurement have some indication of how long it can continually source this level of power? A 1400 MW pumped storage facility is not that useful if it can only source this amount of power for a minute before depleting its stores, for example. Or is the power figure always chosen s.t. it can continually source this much during peak demand without depleting?
- cesis 10y agoIt is common to use such metric for all generation and it is the maximum power facility can generate. The other metric used is 'capacity factor'(you probably are looking for this)
- wodenokoto 10y agoThe article does tell you what that number means. 1.000.000 homes can be powered by the hydro plant, though you are right that it doesn't say anything about for how long stretches of time, but since it is supposed to act like a battery for solar, maybe 1 day is more than enough.
