A structural question arises when evaluating the California Independent System Operator (CAISO) expansion. What will drive the greenhouse gas (GHG) reductions in a regional independent system operator (ISO) or regional transmission operator (RTO) that spans multiple states and out of state transmission and generator owners?
To answer this question, we will discuss how California, other states, and the federal government address or will address reductions from electric generation. What becomes clear from this discussion is that GHG reductions requirements are separate and apart from wholesale electric markets and that wholesale ISOs/RTOs respond to state policy but are not platforms to drive state policy in light of their federal nature.
Our discussion will address California, the Regional Greenhouse Gas Initiative(RGGI) in the New England and Mid-Atlantic, and the Clean Power Plan.
