LCG, April 30, 2026--OG&E, the operating subsidiary of OGE Energy Corp., announced today that it will power three new data centers that Google announced in Muskogee and Stillwater, Oklahoma last year. As part of the agreement, Google will also make power generation capacity available from two solar facilities in Stephens and Muskogee Counties that are currently under construction. The data centers and associated Electric Service Agreements are expected to provide economic growth for local communities and the state, contribute to grid stability, and benefit OG&E's current customers.

LCG, April 29, 2026--Graphic Packaging Holding Company today announced a virtual power purchase agreement (VPPA) with NextEra Energy Resources, LLC. With the VPPA agreement, NextEra Energy Resources plans to build the Selenite Springs Energy Center, a 250-MW solar energy facility in West Texas, and Graphic Packaging will be the sole buyer of the facility's renewable energy attribute certificates. Graphic Packaging, a global provider of sustainable consumer packaging, expects the agreement to cover approximately 43 percent of its 2025 electricity usage in the U.S. and Canada. The agreement will advance Graphic Packaging's commitment to source renewable electricity and reduce its greenhouse gas (GHG) emissions.

Scientists Figure Out How to Check Steam Generator Bolts
LCG, Sept. 12, 2000--Scientists at Southwest Research Institute have modified the cylindrically guided wave technique to detect and characterize borated water corrosion in the all-thread bolts used by the nuclear power industry in heat exchanger flanges, the institute said yesterday in a fairly technical news release.The steam generators in nuclear power plants are sometimes called heat exchangers. They are full of hundreds of tubes hooked to big pipes. Where the big pipes connect to the reactor coolant plumbing the connections are flange-to-flange and bolted together with big bolts that can be 20 inches long and an inch and a half in diameter. The bolts have threads their entire lengths and are secured with nuts at each end.All you see from the outside is the end of a bolt and the nut, so when the bolts are inspected workers look for discoloration. If the end of the bolt looks funny, the plant is shut down and the bolt is removed for a closer look. This is a very expensive process.What the scientists at Southwest Research have come up with is a way to use ultrasonic energy to check for corrosion. When there is a leak in a flange even one you can't see the water gets at a bolt and can corrode it. The water has had borate added to it to minimize corrosion.Now, the borated water doesn't corrode the bolt so it looks rusty, as ordinary water might. As the borated water corrodes the all-thread material it leaves a very smooth, almost polished surface. This smooth surface allows the ultrasonic mode-converted signals to form and produces the information needed to assess damage.The scientists call their method the "cylindrically guided wave technique" and like to use the initialism "CGWT." Dr. Glenn M. Light, director of the Southwest Research nondestructive evaluation science and technology department, said using CGWT on all-thread bolts was something new. "We developed this technique about 20 years ago for inspecting any bolt except all-thread," he said. "Borated water corrosion presents unique circumstances that enable inspectors to use CGWT in a slightly different manner than has been used previously."
