Renewable ramps made start time a procurement criterion
Grids with substantial solar penetration face an evening ramp arriving on a predictable daily schedule at a rate that heavy duty machines taking half an hour to reach load simply cannot follow, and system operators have begun specifying start capability rather than treating dispatchable megawatts as interchangeable. A machine at full output in nine minutes captures pricing that a slower unit misses entirely. That reframing is worth more to these manufacturers than any efficiency improvement, and it is arriving in more markets each year as variable generation shares rise. Rules move this market.
