By conducting annual cost of service studies, Park Electric sets rates to recoup adequate revenue for the purchase of wholesale power as well as maintain and operate the system. Revenues must allow Park Electric to repay long term financers (Rural Utilities Services or RUS and others ), generate margins (money that becomes capital credits) and satisfy the terms required by RUS and the Cooperative Finance Corporation (CFC).

Park Electric's rates reflect a fair and equitable schedule for each class of service. These rates assure that one class of service, whether commercial, residential or irrigation, does not subsidize another.
