Re wholesale rate of 3 cents per kwh -- that excludes costs of a battery storage system which they are also paying for:

The new 100-megawatt (MW) solar array and an accompanying 30-MW energy storage system are expected to be in service by the end of 2019. Together with a planned 100 MW wind project, the new system will give TEP a renewable portfolio that produces enough clean energy each year to serve the annual electric needs of nearly one out of every three Tucson homes. Excluding the cost of storage, TEP will buy the system’s output for 20 years for less than three cents per kilowatt hour – less than half as much as it agreed to pay under similar contracts in recent years.
