Specifications include, but are not limited to: Task #1 Site Visits The energy auditor(s) from the selected firm (auditor) shall conduct site visits to review WWS and/or DWS equipment and systems with staff, collect energy usage and equipment data, and develop costsaving recommendations. NHDES will provide available operational data, electric energy use data and energy benchmarking analysis results to the auditor prior to the site visits. Attachment A includes an initial list of the priority NHDES-selected WWSs and DWSs. Additional facilities will be added to the list as they are identified and prioritized throughout the duration of this contract. The auditor shall work with NHDES for scheduling site visits. NHDES and/or operators from other WWSs or DWSs may accompany the auditor during the site visits. Task #2 Energy Analysis and Report Development The auditor(s) shall conduct detailed process level energy audits and data analyses that include the following: • Energy Balance o An overall electric energy use profile to determine how electric and fuel energy is used for each process within the WWSs and DWSs. Collection and distribution equipment will be included as a process. o Where available, the auditor shall use the installed/name plate horsepower for each piece of equipment included in the audit. If this information is not available, the auditor shall use measured horsepower. • WWS and DWS Process Analysis o Analysis of each applicable (energy using) process aimed at identifying potential opportunities for gains in operational efficiency through the following measure categories: Energy Management Practices (EMPs), which include activities or procedures that are considered “good efficiency practices” but may not have measurable cost savings. Operational Measures (OMs), which are cost saving projects that pay for themselves in less than a year, and do not require significant capital. Energy Conservation Measures (ECMs), which are traditional energy projects that require a significant capital investment and typically have a simple payback of 1 to 10 years. Longer paybacks can be considered in cases that make sense coupled with other upgrade plans or with other faster payback measures. Energy Supply Measures (ESMs), which include projects or activities that reduce energy costs but not energy use. These measures include rate schedule changes, savings with an alternative energy supplier, demand charge monitoring/control measures and at times, renewable energy measures.
