ESA Letter to MISO on AGC Enhancement
ESA submitted comments to MISO that can be summed up most simply as generally supportive of MISO’s direction but unable to provide a better judgment until more information is available on its AGC Enhancement proposal. AGC Enhancement is a necessary and important step to enabling greater grid flexibility, and at a general level, we favor MISO’s intent to enable faster response of all resources. However, the details of that implementation will have significant impacts on whether advanced energy storage is able to be fully utilized, given its uniquely fast response and ramp capabilities, as well as whether existing market products are sufficient to take advantage of that AGC Enhancement.
