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 twenty five year history, PGS employees have kept the plant operating at least ninety percent of the time in five different years. In 2006, PGS was available 95.9% of the time. This reliability level was only one tenth of one percent below PGS's highest availability record of 96.0% set in 1998. Achieving high plant availability over the last several years has directly contributed to the continued production of low cost power and the good financial performance of the utility.
