The coal-fired Four Corners Power Plant near Farmington, New Mexico, will provide less power to Arizona under a new operating plan, Arizona Public Service Co. said Friday. What is new is that one of the two generators at the plant will only operate seasonally starting in fall 2023, while the other continues to run year-round, according to APS. “Four Corners has provided reliable and affordable electricity for almost 60 years, fostering economic growth and prosperity in cities and towns throughout the region,” said Jacob Tetlow, APS senior vice president of operations. “With seasonal operations, the plant will continue to be a critical source of reliable electricity when our customers need it most and enable a responsible transition to a cleaner energy future.”
