TheRGGI states – Connecticut, Delaware, Maine, Massachusetts, Maryland, NewHampshire, New York, Rhode Island and Vermont – use a market-basedcap-and-trade program to reduce greenhouse gas emissions from regional powerplants, selling nearly all emissions allowances through auctions.
TheRGGI participating states are currently undergoing a program review, with afocus on dovetailing the program with the implementation of the Clean PowerPlan. The current RGGI cap extends until 2020, while the Clean Power Plancompliance period begins in 2022 and ends in 2030.
Aftera comprehensive review in 2013, and in an attempt to bring the RGGI cap withactual emissions levels, the participating states trimmed the ceiling by 45%,to 91 million tons, in 2014. The RGGI emissions cap declines 2.5% each yearthereafter through 2020. The 2016 RGGI cap is 86.5 million tons.
Asthe ongoing RGGI program review heads into the final months of the year, theCollaborative for RGGI Progress, which includes the Acadia Center, , , National Grid andNatural Resources Defense Council, recently submitted comments/recommendationsto RGGI outlining that the RGGI program reduction trajectory should continuethrough 2030 in order to comply with the Clean Power Plan.
"RGGIhas modeled a 5% reduction region-wide, which would go a long way towardmeeting the 80% by 2050 goals. The group could endorse such a target if thecustomer bill impacts and electric system reliability implications wereprojected to be reasonable," the group said in its comments.
Additionally,RGGI could continue to implement a limited cost-containment reserve, but itshould be limited in size so that the reduction each year is no less than 2.5%.
"Priorto the next program review in 2020, RGGI should evaluate the need to adjust forthe private bank of allowances existing as of Dec. 31, 2020, by reducing theannual caps over time to account for the bank, similar to the method used inthe 2012 review. Implementation of any adjustment should commence after 2020,"the group said.
