Generator Maintenance Plans

Preventive Maintenance Service Plan

The purpose of a Preventive Maintenance Service Plan is to insure more reliable performance of a diesel or gas-fired generator when it is needed for an emergency. A Plan also ensures that any warranty claims to the parts manufacturers can be supported with evidence of routine maintenance. The following Plan levels offer different degrees of preventative maintenance, and priority of service during an outage event. Greenfield Energy’s 24-hour emergency services are available to all of our customers, but priority of response is described below for Plan customers.

Preventive maintenance does not guarantee that generator parts will not have a sudden failure due to unforeseen issues.
