1) REQUEST FOR QUALIFICATIONS (RFQ) OVERVIEW

a) General

I) Introduction and Purpose

The City of Monroe, North Carolina Energy Services Department (“City”) is soliciting

qualifications from qualified firms to provide professional services for the engineering,

procurement, construction management, and commissioning support associated with

an expansion of the City’s existing Liquefied Natural Gas (LNG) peak shaving facility.

The purpose of this Request for Qualifications (RFQ) is to identify firms with demonstrated

experience in the design, expansion, and modification of LNG peak shaving facilities,

including regulatory compliance, safety, construction management, and integration

with existing operating facilities. This RFQ is intended to evaluate a firm’s qualifications,

experience, technical capabilities, and overall suitability for the Project.

II) City of Monroe / Energy Services Overview

The City of Monroe is the county seat of Union County, North Carolina within the rapidly

growing Charlotte metropolitan area. The Energy Services department is committed to

providing cost-effective, courteous, and customer-oriented operations to continually

enhance the quality of life for the citizens of Monroe.

The City of Monroe Energy Services owns and operates a natural gas system that

provides energy to approximately 14,400 customers consisting of residential,

commercial and industrial customers over 5,000 DT per day loads. The City of Monroe’s

Natural Gas Division operates and maintains 43 miles of natural gas transmission

pipeline, 555 miles of natural gas distribution mains, 25 regulator stations and an LNG

peak shaving facility.

III) Project Background and Objectives

The City’s LNG peak shaving facility at 2111 Morgan Mill Rd, Monroe, NC, has been in

operation since 2020. The facility plays a critical role in ensuring system reliability,

managing peak demand, and maintaining cost-effective natural gas supply during

high-demand periods. The rapid growth in the area is causing an increase in the natural

gas system peak demands. This expansion is required to enhance system reliability,

increase peak supply capability, and support anticipated future load growth. The

Project is expected to include modifications and/or additions to existing LNG

infrastructure, including but not limited to storage, vaporization, process systems,

controls, and supporting facilities. The original siting and design included provisions for

this expansion.
