Conclusions

  • EIM dispatch reduces GHG emission by 291,998 MTons for

the period January-June 2016.

  • The secondary dispatch GHG effects associated with EIM

transfers to into the ISO to serve load are offset by the GHG reduction effects associated with transfer out of renewables resources displacing external emitting resources.
