Waste Water Facility Energy Audit

To approve the contract with Process Energy Services for an energy audit of
the wastewater treatment facility in an amount of $22,800. Funding will be
through: Department: 169 - Wastewater; Fund: Grant; Activity) NH-DES
Energy Audit.

Process Energy Services Energy Audit Scope and Fees

The New Hampshire Department of Environmental Services (NHDES) is
conducting an energy savings initiative in conjunction with the United States
Department of Energy. This initiative involves auditing wastewater treatment
facilities across the country. A large number of wastewater plants in New
Hampshire are taking advantage of this, and all are seeing a potential energy
savings and cost reduction when suggested changes are implemented. NHDES
is using one company for the energy audits, Process Energy Services.

Some of the benefits of an energy audit include determining simple operational
measures that can result in energy savings for low cost changes, evaluation of
past projects to promote energy efficiency in upcoming projects, and
identification of other changes and upcoming planned projects that could result
in energy savings.

The total cost for Nashua’s audit is funded through NHDES as part of its
energy savings initiative ($20,000) and a US Department of Energy grant
($2,800).

Process Energy Services has done energy audits at other plants in the State,
and typically identifies savings of around 34% in energy costs. This is the
company the NHDES is using for this program and they are well suited to
identify energy savings at the Nashua Wastewater Treatment Facility.

RE: Proposal for a Comprehensive Process Energy Evaluation
City of Nashua Wastewater Treatment Facility & Pump Stations

Dear Bill,

Process Energy Services is pleased to submit the enclosed proposal for energy evaluation services
for the Nashua Wastewater Treatment Facility and thirteen-collection system pump stations.

Proposed Scope of Work

We have recommended a comprehensive approach that is based on our experience conducting
energy evaluations for facilities throughout New England. The approach outlined in this proposal
provides a detailed review of the process and building systems.

An overview of the energy evaluation scope of work is provided below.
Task #1 Site Visits

To properly evaluate all facility process and building systems, we will require several site visits to
review facility equipment and systems with staff, collect energy usage and equipment data, and
develop cost savings recommendations. The site visits will include the following:

Detailed facility review and equipment testing with plant operator.
Collection of equipment nameplate data.
Performing equipment efficiency tests on major equipment with a motor nameplate of over
10 hp operating at least 50% of the time. Testing will include pressure, flow and electrical
measurements. For this task, we would like to request that the facility provide the services of
an electrician or an operator comfortable opening up electrical panels.

e Installation of data loggers on selected equipment.

During our site visit(s), we would also like to review the following information:
e Facility O&M manuals & plant drawings

e Specification data for all major equipment (i.e. pump curves, performance data) and historical
maintenance costs for each system.
