Prescribing Ramp up and Ramp down rates for thermal power generation capacities
#2
First check if your version of ANSWER-TIMES already supports the parameter ACT_UPS (e.g. look for it under the Parameter Tab).
If it does, you can use that for defining the ramping limits: UP = ramp-up, LO = ramp-down.
Unit is fraction of nominal on-line capacity per hour.
If it doesn't, consider upgrading to the latest version of ANSWER-TIMES.

The unit MW per minute does not seem very useful to me: If the data says 1 MW per minute, the same rate can hardly be valid for a 100 MW plant and a 1000 MW plant. I guess you would then need to have ramp-rate data table for all possible plant sizes?
In TIMES, you need to assume a certain plant size fore each technology in order to define e.g. the appropriate investment costs. And so, you can look up that size in your ramp-rate data table (where the ramp-rate is given in MW / minute, for all plant sizes).
