Test Your Knowledge: Boiler Chemical Cleaning

Most engineers and operators know (or should know) that boiler tubes containing deposits create long-term reliability problems for the boiler. Long-term overheating of the metal will result from prolonged operation with heavy tube deposits. The tubes will first bulge and then fail. Because the deposits tend to be widespread, this generally means that large sections of […]

Texas Utility Ready to Ramp Up Renewables

The CEO of Texas-based CPS Energy said March 6 that the utility wants to generate at least 50% of its power from renewable sources by 2040, part of a plan that includes the addition of 550 MW of battery storage, as it looks to reduce its dependence on fossil fuels.

Public Service Co. of New Mexico (PNM) closed Unit 2 and 3 of the four-unit San Juan Generating Station (SJGS) near Farmington, New Mexico, in December 2017. Unit 2 came online when the plant opened in 1973 and is the oldest unit at San Juan. Unit 3 began operation in 1979. The shutdown of these two units will result in the reduction of energy generation of approximately 836 MW. PNM plans to replace the loss in generation with a diverse mix of increased renewable energy, existing nuclear power, natural gas generation, and increased power capacity from Unit 4.
