Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_76085 ( "Name" text, "Year commissioned" real, "Gross head (metres)" real, "Installed capacity (megawatts)" real, "Average annual output (million KWh)" real )

### Question ###
What is the Year commissioned of the power station with a Gross head of 60 metres and Average annual output of less than 59 million KWh?
