PV power for monitoring natural gas wells in Canada
Thousands of natural gas well heads are scattered around the countryside of central Alberta, Canada. In order to optimize the operation of these wells, gas companies install electronic equipment that monitors and, in some cases, controls the gas flows. This electronic equipment, generally known as a SCADA system, keeps in contact with a central pumping station by means of a radio, which receives and transmits signals for about one second each minute. The SCADA equipment requires a small but reliable supply of electricity.
