Request for Proposals
Microgrid (Solar Photovoltaic Generation System
and Battery Energy Storage) System and DC Fast Charger - Police Department
1. Introduction
The City of Decatur ("City") is seeking proposals from qualified vendors to provide turnkey
services for design, bid assistance and construction administration for the installation of a
microgrid system that includes solar photovoltaic (PV) generation system and battery energy
storage system (BESS) and DC Fast Charger at the Decatur Police Department, 420 West
Trinity Place, Decatur, Georgia 30030. The City invites firms to submit proposals responsive
to the specific requirements set forth in this request for proposals ("RFP"). The expected start
date for this project will be determined following coordination with Georgia Power and project
award.
2. Background
The City of Decatur has received a federal grant from the U.S. Department of Energy (DOE) to
support the installation of a microgrid system that includes solar photovoltaic (PV) generation
system and battery energy storage system (BESS) and DC Fast Charger at the Decatur Police
Department. The project is intended to improve the facility's energy resilience, reduce reliance
on the electric grid, and provide the capability to maintain critical police and municipal court
operations during an extended utility power outage.
While final system sizing will be determined during the completion of the project, initial
estimates include a:
170 kW roof-mounted solar array
*
250 kW/500 kWh (power and capacity, respectively) lithium-ion battery energy
*
storage system
DC Fast Charger for electric vehicles
*
The Decatur Police Department facility provides essential public services, including police
patrol operations, investigations, and municipal court functions. Maintaining electrical service
at this facility during an emergency is critical to the City's public safety and continuity-of-
government operations.
This project is intended to offset a portion of the Police Department's electricity usage through
on-site renewable energy production and provide backup power for critical loads during
outages. It is the intention of the City that the solar array and battery storage system installed
through this project can be expanded or improved upon in the future as technically and fiscally
feasible.
3. Project Purpose
The City is seeking qualified professional engineering services to develop a detailed microgrid
design for the Decatur Police Department and the design for the installation of a DC fast
charger for electric vehicle charging. The design shall optimize the operation of the proposed
solar PV and battery energy storage systems under both:
8

a. Normal grid-connected conditions, including optimization of on-site renewable
energy generation, battery charging and discharging, peak demand management,
participation in Georgia Power customer-sited resource programs, and other appropriate
energy management strategies; and
b. Emergency grid-islanded conditions, allowing designated critical loads at the facility
to remain operational during a utility outage through coordinated operation of the solar
PV system, BESS, existing electrical infrastructure, and other applicable components.
c. The selected firm shall provide a design set of plans complete for bidding for the
installation of a DC fast charger for EV charging.
d. The City's objective is to install a reliable, safe, durable, and maintainable DC fast
charging system that can support municipal fleet operations.
e. The selected firm shall be responsible for identifying and addressing all requirements
necessary for a complete installation, whether or not each individual component is
specifically identified in this Scope of Work.
The completed design documents will be used to develop a subsequent construction bid
package for procurement and installation of the microgrid system and DC fast charger.
4. Scope of Work
The City of Decatur is seeking proposals to identify a firm with the capabilities to provide a
microgrid system that includes solar photovoltaic (PV) generation system and battery energy
storage system (BESS) and DC fast charger for the City's Police Department.
The selected consultant shall provide the professional engineering, electrical design, technical
analysis, construction-document services, assist with the development of the bid documents for
the micro-grid system, provide construction administration services through installation,
commissioning, testing and interconnection with Georgia Power, at a minimum:
Review the existing electrical documentation, utility information, facility
*
conditions, and available load data.
Conduct field investigations necessary to verify existing electrical infrastructure and
*
site conditions.
Develop an updated electrical load profile for the facility and identify existing and
*
proposed critical loads.
Evaluate and establish the appropriate sizing and configuration of the solar PV and
*
BESS systems.
* Evaluate and establish the appropriate sizing and configuration of the DC fast
charger.
9

o Conduct site investigations and field verification.
o Develop final engineering and construction documents.
o Verify existing electrical and site conditions.
o Determine required electrical service capacity.
o Coordinate with the serving electric utility.
* Review facility as-built structural drawings and relevant code requirements. A
desktop review based on available structural documents and code will be performed
to determine facility suitability in supporting rooftop solar PV.
* Determine preferred rooftop solar PV racking concept based on structural review.
Develop a microgrid architecture that integrates the solar PV system, BESS, utility
*
service, facility electrical distribution system, and associated controls.
Develop a strategy for automatic transition between grid-connected and islanded
*
operation.
Define the critical loads to be served during an emergency outage and evaluate the
*
duration for which those loads can reasonably be supported.
Develop an energy management and microgrid controls strategy addressing normal
*
and emergency operating modes.
Evaluate battery charging and discharging strategies, including opportunities for
*
peak demand management and optimization of solar generation.
Evaluate the need for switchgear, protective devices, controls, transformers, meters,
*
disconnects, and other electrical equipment necessary for safe and reliable
microgrid operation.
Coordinate the proposed system with the existing utility service and electrical
*
distribution infrastructure.
* Address utility interconnection requirements and coordinate with the applicable
electric utility.
* Evaluate system protection, grounding, arc-flash considerations, fault-current
impacts, and safe transition between grid-connected and islanded modes.
* Develop one-line diagrams, electrical plans, equipment layouts, schedules, details,
specifications, and other drawings necessary for construction bidding.
* Develop technical specifications for the solar PV, BESS, microgrid controls,
switchgear, inverters, and associated equipment.
