The New York Public Service Commission’s (PSC) Clean Energy Standard (CES), adopted in August, includes a new emissions credit—the ZEC. The ZEC, or zero-emissions credit, is the first emissions credit created exclusively for nuclear power.
The ZEC is the result of a highly politicized effort to support New York’s struggling nuclear power plants. New York’s four nuclear plants account for 31 percent of the state’s total electric generation mix. According to the PSC, “losing the carbon-free attributes of this generation before the development of new renewable resources between now and 2030 would undoubtedly result in significantly increased air emissions due to heavier reliance on existing fossil-fueled plants or the construction of new gas plants to replace the supplanted energy.” The ZEC Program is intended to keep the state’s nuclear plants open until 2029 and provide an emissions-free bridge to renewable energy.
