Performance Standard 2 - Lighting Performance and Planned Maintenance (PS2)

This performance standard measure:

•  The number of units in light

•  The quality of lighting delivered

•  The regimes in place to periodically measure, test, inspect and clean the Apparatus

The Output Specification sets out the service delivery requirements for each of these measures and the performance targets that the Service Provider is expected to meet.  Performance against the targets set out in the Output Specification will be measured through a range of systems, including:

•  The measurement of street lighting units in light, either from a visual inspection or other relevant monitoring process of each unit

•  The photometric testing of the delivered light output, which is to be performed on a sample basis

•  The planned maintenance arrangements in place for the Apparatus.

The operation of the measure of the percentage of lights in light is dependent on a regular monitoring regime.  To enable the operation of the adjustment, Bidders are required to propose a monitoring regime.  This outage detection system should as a minimum, check the performance of each column on an equal number of occasions at least once per month and in accordance with a regular pre-defined programme.  The Authority should have the opportunity to take part in or 'shadow' the monitoring regime.  The Authority has the right to terminate the Contract for Service Provider default once the percentage of lights in light falls below [93%].

The quality of light output will be tested on a sample basis in order to generate a percentage of lights meeting the designed light output.  The adjustment is designed to increase in significance as the quality of light deteriorates.  The Authority has the right to terminate the Contract for Service Provider default once the percentage of lights meeting the designed light output falls below [50%].

The planned maintenance arrangements will be reviewed by assessing the number of failures to carry out planned maintenance work in a specific month.  The total number of failures will be multiplied by a standard adjustment value to calculate the total adjustment due.  Specific parts of the planned maintenance arrangements will also generate an adjustment based on the number of days before the planned work is eventually carried out.

The deduction regime under PS2 is designed to incentivise the Service Provider to provide the standards of service set out in the Output Specification and deductions escalate for lower levels of attainment to reflect the risks and costs of service failures.
