Keep in mind that this number will vary depending on generation mix. Specifically, it will depend on the response time of your dispatch-able generators. If your primary source of non-renewable generation is big steam turbines with a painfully slow ramp-rate (e.g. coal generation) then you're going to have a bad time.

Which is why most coal in the US is being displaced by combined cycle natural gas turbines; ~10-30 minute ramp, depending on load demand. http://www.utilitydive.com/news/a-users-guide-to-natural-gas-power-plants/259104/ http://www.utilitydive.com/news/a-users-guide-to-natural-gas...
