Timers are not a bad idea and are used in many applications.

Timers are not a bad idea and are used in many applications, but the savings that can be derived from using them is highly variable depending on the type of equipment controlled, the normal hours of operation, type and sophistication of the timer (and user), and the actual timer settings programmed or used. These variables make it difficult to predict energy savings, which is what incentives are based on.

Occupancy sensors on the other hand are a easier to categorize by application type, and savings from occupancy sensors have been independently documented which makes it easier to predict the potential energy savings and evaluate installations in various applications. Occupancy sensors also prevent the possibility of having an occupant stranded in an unlit space because the lights controlled by an occupancy sensor will automatically come on if motion or heat is detected in that space. For areas where the coverage from a single sensor cannot control the entire area, additional sensors should be installed. There are even sensors that mount to individual light fixtures for additional coverage if needed, but often a single sensor can control a large area.

Focus on Energy information, resources, and financial incentives help to implement projects that otherwise would not be completed, or to complete projects sooner than scheduled. Since many timers are very inexpensive and result in a fast payback, an incentive is not needed to help the end user move forward with installing a timer if it makes sense for their application.
