Statistical Information

Conventional appraisals of power plant operations include availability (a measure of reliability), cost-effectiveness, safety record, and compliance to environmental protection regulations. Platte Generating Station has achieved noteworthy successes in each of these areas over the years.

During its thirty year history, PGS employees have kept the plant operating at least ninety percent of the time throughout the years. In 2011, PGS was available 95.7 percent of the time.  Achieving high plant availability directly contributes to the continued provision of low cost power and good financial performance of the utility.

Five Year Overhaul


As noted above, the utilization of a generating unit is measured by its "capacity factor".  This is a ratio of the amount of power generated to the maximum amount of power the unit could generate if operated at full output. 

While operating and maintaining PGS for maximum availability is a primary goal, running the plant as efficiently and cost-effectively as possible is nearly as important. PGS remains a top ranked power station when cost issues are considered. Using the most recent data available (from 1995), PGS ranked as the 20th most cost-effective power plant nationally among a total of 619 stations. This ranking is particularly gratifying because PGS once again is the smallest plant on the list. PGS doesn't have many of the advantages which larger, multi-unit, "mine mouth" plants have such as shared systems (coal conveying, ash handling, warehousing, etc.) and close proximity to low cost fuel resources. PGS's excellent production costs directly result from favorable delivered coal prices and effective plant operations and maintenance.

In the 1990's operating a power plant in strict compliance with environmental protection legislation is paramount. In 1996, PGS achieved an exceptional environmental compliance record as a direct result of the commitment, knowledge, and skill of individuals responsible for operating the plant, maintaining emissions monitoring equipment, and managing through the maze of continually changing environmental rules, regulations, permits, and reporting requirements.

PGS's 1996 safety record contained several positive accomplishments. During the year, we logged nearly 90,000 working hours were logged without a lost time injury and the station's coal handling crew safely unloaded and handled more than 350,000 tons of coal from 31 trains during frequent extreme weather conditions.
