The manpower necessary for the operation of the plant naturally depends on the degree of automation, the scope of own wood chip handling, the age of the heating plant etc. Individual small heating plants are designed so as to remove the need for permanent on-site attendance even during the day. By being on call via telephone and daily inspections, the plant manager can occupy another job at the same time.
When estimating the manpower required, the calculation can be based on systems from approx. 1.5 MW to 5 MW requiring approx. 1-2 man-years for the operation. Systems above 5 MW will require approx. 2-3 man-years for the operation.
The construction of the system is of decisive importance to the amount of maintenance work.
