A combination of factors, including a relative scarcity of projects, has cut demand for skilled labor in the power generation sector. Despite the lull, workforce retirements are still expected to challenge the industry.
Like swallows returning to Capistrano or geese flying south in the fall, the cycle of spring and autumn maintenance outages at electric power generating stations is almost a force of nature. Low demand for electricity during shoulder seasons means that units can be shut down for routine repair and upgrades, and then returned to service to meet summer and winter high-demand periods.
