can make an informed decision about whether to further pursue this option. Regardless of the
community's choice, Siemens recommends the incorporation of a 7-pin photocell receptacle so that at a
minimum, the LED fixtures installed via this project are “controls ready” so that wireless controls could
be incorporated at a later date following Eversource tariff acceptance and if the future project
cost/benefits are deemed acceptable by the City/Town.

Construction

After reviewing the quotes, the decision was made to present Leotek/Cimcon pairing in our base
proposal since the combination of initial capital cost and 10-year operating costs were the lowest. For
reference and further consideration, Acuity pricing was approximately 15% higher across the board, and
Philips was approximately 46% higher. However, we also understand that the City may have other
priorities and factors which may lead to selection of a different controls manufacturer.

We specialize in maintenance, so we gravitate toward lighting fixtures that are well-designed and
provide the longest proven maintenance-free service. We have extensive experience in assisting in the
selection of appropriate fixtures, performing test installations, light level studies, and helping our
customers promote the financial and environmental benefits of the initiative. Our objective is to
provide both vendor neutral and objective information to the City, enabling informed decisions at each
project phase.

Fixture Selection

4. Implementation and operational costs associated with each measure are then determined.
Estimated construction costs are compiled by the Energy Engineer and Operations Manager.

5. Feasibility of ECM’s (cost vs. savings) is then examined by the Energy Engineer. A draft list of
feasible ECM’s are developed based on the financials.

e Accurate existing fixture counts by road and area type to be used as an input for LED fixture
selection/lighting design, material cost estimates, fixture procurement, and_ installation
purposes

e Aninventory database for asset management and future maintenance needs

The following is a step-by-step overview of the audit process:

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:
