Creating Efficiency Solutions Throughout Illinois

About 80% of commercial & industrial facilities still run ineffective, costly, and inefficient lighting systems. In many cases, these facilities are spending 3-4 times more than they need to run outdated technology, while failing to meet IES recommended light-levels.

With PEC, you will access an LED retrofit solution that is optimized and scalable to best reach your business goals:

  • Fixtures and optics to provide optimal light where you need it most (and not where you don’t)
  • Sensors and control systems to turn on, off, brighten, or dim depending on activity to maximize efficiency
  • A go-to expert by your side post-installation to handle any potential issues or warranties as they arise

Our Step-by-Step Process

Energy Assessment - LED Lighting Retrofit

1. Energy Assessment

Every project begins with a complete assessment of your unique lighting needs and objectives. We discuss how you’re currently using your space, review existing technologies, and establish clear directives for how to add value to your building.


Get started

Our Process - Energy Audit

2. Energy Audit

We’ll perform a free, comprehensive on-site assessment of your current light system — measuring precise level–light-levels, foot candles, fixture counts, and establish a baseline. From this we’ll understand exactly how to provide the lighting system you need to will develop a selection of options for review.

3. Lighting Design & Control Services

We use 3D design software visualize the latest in lighting technology in your space. The result? A customized 3D model of your site incorporating our solutions — including projected light levels and photometrics. By comparing your existing system to our proposal, you’re able to “try before you buy” and witness the impact on your facility.

Experts in Illinois Utility Incentives

Collecting incentives is a cumbersome process. Our team of specialists will handle it for you.

Energy Incentive Specialists

Illinois power providers — including Ameren and ComEd — offer incentive programs that allocate rebates to commercial and industrial businesses that can be applied towards energy-efficiency projects. These incentive programs are designed to lessen the overall demand for electricity around the state, as well as help reduce overall GHG emission output.

To help with this often confusing and time-intensive process, PEC’s in-house incentive team will work directly with your utility provider to capture the max amount available for your project. Your incentive should feel like a discount, not project of its own.

100% of gathered incentives apply directly to your project.

Frequently Asked Questions

An LED retrofit is a replacement of existing inefficient lighting fixtures with energy efficient LED (with or without control systems).

While seemingly straight forward at its core, a one-for-one bulb swap will not maximize efficiency and can even cause some major headaches if done improperly. 

That’s why it’s critical to work with an experience LED retrofit contractor like PEC, where we will design a system leveraging the best fixtures, optics, sensors and control systems to help our clients access the maximum amount of efficiency while also making huge improvements to the overall lighting quality in their facilities. Learn more on this page about our LED retrofit services.

To complete a thorough audit of your space, a PEC Sales Engineer will perform an on-site evaluation of your facility and work with you to determine:

  • The total number of fixtures and fixture types, their locations, heights, and how they are controlled.
  • Ceiling structure and height.
  • The building’s usages and existing light levels (measured by foot candles).
  • Areas of importance to your business in order to design optimal lighting specific to your needs.

In addition to assessing your current lighting system, we will also evaluate the environmental conditions of your space like airflow, dust, moisture levels, temperature, chemicals, and indoor/outdoor spaces to help us design an efficiency solution for your unique needs.

Energy audits are free when working with PEC! Please note that we do only audit commercial spaces — get started by filling out the form on this page to see if our auditing services make sense for your facility.

Energy incentives are funds that utility providers across the US will allocate towards qualifying energy efficiency projects. As a ratepayer, your company is likely already paying into your utility’s energy efficiency program fund.

Navigating the world of incentives can be a complex, time consuming process. That’s why PEC has put together a team of in-house incentive experts to handle the process for our clients, helping you receive the max funding available towards your incentive project, while staying focused on your day-to-day duties.

You bet. When you work with PEC, we will handle the entire LED retrofit process from end to end.

Here’s how the process flows step by step:

  1. Energy Assessment: Begin with an energy assessment to learn your project goals, facility layout, current challenges and pain points.
  2. Energy Audit: We’ll complete a thorough, on-site audit of your current lighting system, where we’ll measure light levels (foot candles), fixture counts, and see how the space is used.
  3. Lighting Design: Modern software allows us to use photometrics and 3D Modeling to design a system optimized for your space.
  4. Incentive management: Your project may qualify for funding through your utility provider’s incentive program. Our team of in experts will handle this entire process for you.
  5. Project Management: Once we’ve nailed down a new system design that you’re happy with, a Project Manager will be dedicated to overseeing your entire project. They will keep you informed about what to expect, schedule contractors and arrange for material delivery and installation.
  6. Installation and completion: Once the install is done, your PM will perform an onsite 100% re-audit to confirm the project was implemented correctly. If everything meets our standards, your PM will schedule a tour with an incentive inspector and we’ll send you any required paperwork to sign off on your completed LED upgrade.

The vast majority of Illionois is covered by two electric utilities:

  1. Ameren IL
  2. ComEd

Beginning January 31, 2023, ComEd released improvements to their already lucrative energy incentive program — making it one of the strongest incentive programs in the country.

See rebates commercial customers in the ComEd service territory may be eligible for in our breakdown here.

PEC has extensive experience working with both ComEd and Ameren IL to collect incentives for various efficiency projects. Learn more about our team of incentive specialists here.
