Implementation Process
In this section, Siemens describes our project approach to turnkey LED streetlight conversions, but first
we will specifically address the RFP question regarding “..the best process to implement the conversion
to maximize utility savings immediately.” We offer the following suggestions to the City, using our
Manchester/Eversource experience as a common reference point:
e Include Eversource staff at regular project meetings between Siemens and City staff to ensure
they are informed and participating in the process from audit to final punchlist phases;
e Require the field audit be conducted in 30 days or less. Siemens and CDM Smith have
completed audits at this rate (e.g., Manchester) so we are comfortable with such a specification;
e {Install and review the ten pilot installations during the field audit with the goal to have a City
decision on the 3000K vs. 4000K specification by the conclusion of the field audit. This will
enable fixtures to be ordered as soon as possible following the audit/reconciliation work;
e Specify a 1-2 week turnaround on the audit reconciliation with Eversource billing inventory;
e Require frequent submissions to Eversource during fixture installations. \|n Manchester, we
were required to submit billing adjustments weekly and we found that Eversource had difficulty
keeping up. We will submit adjustments at whatever interval Eversource and the City agree is
acceptable. Siemens carefully documented all submissions, providing the City with the ability to
pursue retroactive credits as appropriate; and
Prioritize the fixtures at the 95% confidence level. \f there are areas that require additional
photometric analysis or unique decorative fixtures, the City may consider authorizing “95% of
the project fixture order and return to the areas that require more study via a contract change
order. This avoids delaying 95% of the City’s potential savings for a small number of lights. The
utility incentive and/or project contingency funds are often used as a potential funding source
for these types of change orders.
Project Approach: LED Conversion
Each of the major project stages is summarized below in chronological order.
Audit
Siemens and CDM Smith will conduct a citywide field audit to reconcile the Eversource billing inventory
with the field inventory and work with the City to confirm the number and type of fixtures to be
included (which could include additional metered or unmetered outdoor lighting). We have proposed
the use of a GIS data collection method utilizing the services of CDM Smith to expedite the audit phase
and provide a web and map-based tool for the execution of the installation of the LED lighting and
future maintenance. The fundamental purpose of the audit is to provide the City with a detailed
financial analysis of the costs and benefits associated with the proposed LED retrofit project to justify
expending funds for this initiative versus other alternative energy efficiency projects. The audit
approach described in this section is based on our extensive experience with LED streetlight projects and
our history of street light maintenance and installation as an electrical contractor. A completed audit for
street lighting helps to provide the following:
e Baseline energy consumption data
e Accurate existing fixture counts for associated utility billing adjustments
e GlIS-based light location data
