A new study finds that the Regional Greenhouse Gas Initiative Inc., a cap-and-trade energy auction, has added $1.6 billion in economic value to its 10 member states, including Maine.
The report by the Analysis Group's Boston office found that customers saved $1.1 billion on electricity bills and another $174 million in natural gas and heating costs during the three years of the program. Maine received $27.2 million from the auctions, spending the bulk -- $22.8 million -- on energy efficiency and other utility programs, as well as energy audits and benchmarking. Nearly $4.4 million went to greenhouse gas programs and program administration. The report found that RGGI generated an economic impact of $92 million in Maine and created 918 jobs.
The 13 carbon-credit auctions generated $912 million across the 10 Eastern states. RGGI works by auctioning off allowances that power suppliers purchase to offset each ton of carbon dioxide deposited into the environment.
