LCG, June 29, 2026--Constellation announced on June 26 that it has filed license renewal applications with the Nuclear Regulatory Commission (NRC) to extend for 20 years the operations of Ginna Clean Energy Center and Nine Mile Point Unit 1 reactors in upstate New York to 2049. Constellation stated that it's decision to invest in these plants to extend their safe and reliable operations into mid-century demonstrates that New York State's renewal of its Zero Emissions Credit (ZEC) program is working as intended. Furthermore, Constellation stated that maintaining its nuclear fleet is estimated to save New Yorkers $50 billion and sustain reliable emissions-free generation resources to serve increasing electricity demands.

New Problem for Cal-ISO: Interruptible Contracts Used Up
LCG, Jan. 23, 2001The California Independent System Operator, whenever it calls a "Stage 2" electricity emergency, orders the state's investor-owned electric utilities to shed load by shutting off power to industrial customers who have signed interruptible contracts in exchange for lower prices.The move can reduce demand by almost 3,000 megawatts and help Cal-ISO avoid ordering rolling blackouts to protect California's shaky transmission grid. The agency declared more than 20 such emergencies last summer and since last fall has kept the state on what seems to be a perpetual Stage 2 alert.Interruptible contracts, it turns out, aren't forever. Companies that signed them didn't agree to send their workers home every day. Permanente Cement Co. on the San Francisco Peninsula, for example, can be asked to interrupt its electric service for only 100 hours per year, a mark that could be exceeded today.Yesterday, Pacific Gas & Electric Co. warned Cal-ISO that it has exhausted the entire allowance for the program in its service territory for this year. That includes most of Central and Northern California."Many times during this crisis, the interruptible program has made the difference between keepingthe lights on and having rotating outages," said Jeff Butler, a PG&E vice president. "Without these customers voluntarily serving as a buffer, the CAISO may have to implement the rotating block outage program much sooner if they are not able to buy enough power to meet the needs of our customers."PG&E has about 170 interruptible customers who can be asked to take 400 megawatts of demand off the grid under a stage 2. The problem will get worse as Southern California Edison Co. nears exhaustion of its interruptible allowances. It has something like 1,500 customers representing 1,200 megawatts of interruptible load. Figures from San Diego Gas & Electricity Co. were not available this morning.The state's power picture improved yesterday as some plants, shut down for repairs after last year's non-stop service, were put back to work. Cal-ISO said 7,600 megawatts of generation was still off line yesterday, but that was a vast improvement over last week when 10,500 megawatts was out of action. The Los Angeles Department of Water and power, the largest municipal utility in the U.S. and unaffected by California's power woes, has been helping Cal-ISO out by selling it surplus power at market rates. Yesterday, the LADWP furnished the state with 550 megawatts and this morning said it has up to 1,000 megawatts for sale today.
