Commercial Solar Built for Joliet Freight Operations

Joliet sits at the I-55 and I-80 interchange, and the warehouses, refrigerated buildings, and plants clustered around that junction carry some of the steadiest electrical load in northern Illinois. Loading that flat, under acres of unobstructed roof, is what makes on-site generation worth modeling rather than estimating.

We are a commercial solar EPC company, which means engineering, procurement, and construction sit under a single contract. Our team models the system against your interval data and designs it, then permits, builds, and sees it through ComEd approval. Joliet is one of the Illinois markets we cover from our Evanston base.

Why Joliet Businesses Are Adding Commercial Solar

Refrigerated space changes the arithmetic of a solar project. Compressors cycle hard against the meter, so a large share of what a cold storage operator pays is demand charges rather than consumption, and an array alone will not touch the worst of those intervals. Pairing generation with battery energy storage, or BESS, lets you discharge through the peak instead of buying it at your highest rate. The same batteries hold refrigeration through an outage, which protects product value that dwarfs the energy savings.

Around-the-clock freight operations shape the build itself. Dock traffic never really stops in the Will County intermodal cluster, so we plan crane positions, roof access routes, and electrical cutovers against your shift and trailer schedule during pre-construction. Nothing about the installation should put a truck in a queue.

Our EPC Approach

One company owns the whole project, from the first roof measurement to permission to operate.

1

Site Assessment and Energy Modeling

We start with twelve months of interval data, your roof and land area, and the electrical service feeding the building. Energy modeling establishes what the site can generate against what your operation actually draws, and financial modeling turns that into a case your finance team can audit line by line rather than accept.

2

Engineering and Design

Our engineers produce the structural, electrical, and layout drawings for your specific building, including snow and wind load calculations, attachment detailing, and protection design. Equipment selection happens at this stage, so procurement follows a stamped drawing set instead of a catalog assumption.

3

Permitting, AHJ Review, and Interconnection

We prepare and carry every submission: state-level requirements, the City of Joliet or Will County as the authority having jurisdiction, or AHJ, and the ComEd interconnection application and coordination through approval. Your staff never moves paperwork between agencies on our behalf.

4

Construction, Commissioning, and PTO

Our construction leadership runs the build, coordinates inspections, and commissions the system under load. You take ownership of a monitored, producing asset with a full turnover package and permission to operate, and O&M is available once the system is running.

Incentives and Financing Options

Federal and state programs move, so we model your project against the rules in force when construction begins.

Federal Clean Electricity Investment Credit

The federal clean electricity investment credit replaced the older energy investment tax credit framework for eligible clean electricity projects, and commercial solar may qualify for increased credit value when applicable requirements are met. For many projects the commonly discussed 30% federal incentive depends on whether the project satisfies applicable rules, including prevailing wage and apprenticeship requirements. 93Energy does not replace your tax advisor, though our documentation keeps your financial team supplied.

Illinois Shines and SRECs

Illinois Shines is the state program that pays commercial owners for the power their systems produce, through solar renewable energy credits, or SRECs. 93Energy is a registered Approved Vendor on the state's official list, which is what allows a vendor to enroll projects and deliver those payments. We model SREC revenue alongside energy offset so the full return sits on one page before you commit.

Depreciation and Financing Structures

Accelerated depreciation can improve the after-tax return, and ownership ranges from outright purchase to structured financing that keeps cash in the operation. Distribution owners with several buildings often phase projects across budget years. We will model the options against your own capital plan.

Industries We Serve in Joliet

Three sectors carry most of the commercial load in this market, and each one changes how we build. Explore the industries we serve below.

1

Warehousing and Distribution

Fulfillment and distribution buildings offer wide, flat, largely unobstructed roof area, which keeps layouts simple and penetrations few. Daytime picking and shipping load lines up well with generation.

2

Cold Storage

Refrigeration runs continuously and spikes hard, so these facilities gain more from storage paired with solar than almost any other building type in the corridor.

3

Manufacturing and Fabrication

Process equipment draws heavy, predictable daytime power. We plan around shift schedules, safety protocols, and roof load limits so production keeps its calendar.

Why Joliet Owners Choose 93Energy

  • Illinois Shines Approved Vendor: Registered on the state's official Approved Vendor list as a distributed generation installer and project developer.

  • One contract, one point of accountability: Engineering, procurement, construction, and development sit under our roof rather than across a chain of subcontracted vendors.

  • All permitting and interconnection handled: State requirements, your Joliet or Will County AHJ, and ComEd coordination are ours to carry.

  • An Illinois company since December 2018: We work out of Evanston and build across the state.

  • Industrial-scale projects on the board: Our portfolio includes a 4MW self storage installation, a 3MW industrial project, and a 527KW heavy manufacturing build.

  • Storage and EV charging in the same build: Battery storage and EV charger installation can be engineered in now or added when the business case arrives.

Frequently Asked Questions

Joliet facility and property managers tend to raise the same five questions before a roof has even been measured.

  • Yes, and the plan should say exactly how. During pre-construction we map crane positions, roof access, laydown areas, and electrical cutovers against your shift and trailer schedule. The only downtime on a well-run job is downtime you scheduled.

  • That depends on system size and review times, though the order never changes. Engineering and design come first, then permitting, then construction, and ComEd interconnection carries through to permission to operate. We sequence equipment orders against the approval calendar rather than ordering early and storing it.

  • Two ways, and both matter. Batteries discharge through your peak demand intervals, which is where a large part of a refrigerated building's bill is set, and they hold refrigeration during an outage so product does not warm.

  • We do, start to finish. That covers state-level requirements, your local AHJ in Joliet or Will County, and the ComEd interconnection application through review, approval, inspection, and permission to operate.

  • Generally the federal clean electricity investment credit, Illinois Shines SREC revenue, and accelerated depreciation. Credit value depends on labor requirements, construction timing, and ownership structure, so we model your case and your tax advisor confirms it.

  • From starting the system design with Allen to Engineering, the set up with Mark and the install with seasoned electrician Nick this was an amazing experience. We installed an Enphase system with battery back up on our single-family home in Chicago. I highly recommend 93 energy for anybody looking for a system in the city of Chicago. This crew knows how to navigate the city  and Comed bureaucracy along with the permitting  and they do it with high quality  and efficiency.

  • You wont find these guys in Homedepot but could not ask for a better solar installer in town. Very down to earth, very responsive, and got the best deal on Enphase among the 7 other companies I called. Locally based and licensed, permit approved in record time, design to instal- 3 weeks, no issues with getting the state or the federal refund checks, full support and transparency from start to finish. Looking for the best deal in Chicago land, look no further and give Mark, Allen and Mitch a call- they will take care of you like they did to me.

  • Price was reasonable and the installation was top notch. I would definitely recommend others if they are going solar to definitely consider 93 energy. The work was completed on time and I can see the benefits from going solar. Rob was quick in responding for any questions or queries I had regarding solar and the installation. Nick did a good job in completing the installation on time.

  • Thanks to the 93 Energy Team, my wife and I are very happy with all aspects of our purchase and installation of our panels from SunPower. Sales and installation from 93 Energy was incompatible. I already have referred you to others.
