Take HVAC projects to the next level with Advanced Rooftop Unit Controls

Advanced Rooftop Unit Controls (ARC) in a nutshell

Unlock better HVAC performance and greater energy savings for your customers with ARC, a retrofit solution that modernizes an existing rooftop unit (RTU). Traditional RTUs with constant speed fans waste energy, especially when demand is low. By automatically adjusting fan speed and monitoring building needs in real time, ARC provides measurable savings and enhanced comfort for your customers.

The components of ARC

  • Unit control – acts as the digital brain of the unit.
  • Supply fan VFD or multi-speed fan motor – adjusts the speed of the fan as needed, rather than running at a constant speed (100%).
  • CO2 or occupancy-based sensor – detects building occupancy with CO2 sensors and automatically adjusts ventilation rates, minimizing unnecessary fan operation.
  • Digitally controlled economizer – brings in the fresh air from outside to help cool your space naturally and reduce the load on the cooling system.

Deliver more value to your customers with ARC

  • Help your customers reduce energy use by 30-50%.
  • Ensure quick project payback in just one to four years.
  • Utilize installation incentives for your ARC projects.
  • Deliver lower utility bills for your customers.
  • Increase the lifespan of your customer’s RTU.
  • Improve occupant comfort.
  • Boost indoor air quality.

Market growth

Did you know?

  • Roughly 60% of commercial floor spaces use RTUs.
  • RTUs make up 20% of all commercial building energy use.
  • 73% of these units rely on basic or manual controls.
  • That’s 1.9 million buildings in the U.S. ready for major energy savings with better controls.

Program changes for Rocky Mountain Power Wattsmart® Business – Wyoming

Program changes for Rocky Mountain Power Wattsmart® Business in Wyoming effective October 24.

Quick Links

Wattsmart® Business is always looking for ways to improve our program and make it easier for you to serve your customers with the best products and incentives. Our program evolves as technology changes, and we gain insights from experience. Rocky Mountain Power is planning updates to the Wattsmart Business program in Wyoming that will be effective October 24, 2025We’ll have new approaches for lighting pathways, new construction/major renovation and non-lighting incentives.

Lighting: Plug and Play Controls Ready 🌟New🌟

We developed this category in response to emerging lighting technology, and it applies to all lighting pathways. Plug and Play Controls Ready lighting offers you flexibility with receptacles that allow for a tool-less addition of controls during installation or in the future. If your customer opts for controls in the future, there’s no need to rewire the system, which cuts your labor costs. Several incentives are available in this category:

  • You may submit for the plug-and-play lighting incentive at the time of installation.
  • If the fixtures include a module, plug-and-play controls can be submitted as a Networked Lighting Controls or Advanced Networked Lighting Controls project, and we will honor the highest incentive for your customer.
  • You may submit for a controls-only project incentive in the future.


See Table Non-Prescriptive Lighting System Retrofit Incentives

Lighting: retrofits incentives

Express incentives

We are introducing an Express path to allow you to apply for most lighting projects on a post-purchase application process, which can be quickly submitted through the new online tool. Unlike past prescriptive incentives that calculated the incentive amount per fixture, Express incentives offer an incentive amount per watt installed and are not limited to specific retrofit kit/fixture categories. Express excludes replacement lamps, controls only, new construction and major renovation, and projects where there is an LED baseline and has different rates for interior and exterior installations.

  • Uses classifications
  • No controls
  • Plug and Play Controls Ready
  • NLCs
  • Luminaire Level Lighting Controls

Small and Medium Business Express (SMBE) incentives

We are expanding the previous Small Business Enhanced category to include medium-sized businesses too. This category uses the Express incentive structure described above, so this new category will be referred to as SMBE.

The original 75% incentive cap still applies, but you have more opportunities to achieve it. Rather than one set incentive of 75%, SMBE offers higher incentive levels.

The Express category excludes replacement lamps, is phasing out the lighting tool and offers you a new eligibility site.

Calculated (non-prescriptive)
Our non-prescriptive path goes by a few names such as calculated, Typical or simply the lighting tool path. We’re making some enhancements to the lighting tool.

The biggest change is that there is one rate for all customer sizes, eliminating segmentation in the tool. The Basic Controls category is being replaced with Plug and Play Controls Ready. This is the exclusive path for controls-only projects. You can receive lighting incentives for most product types in the tool, with the exception of replacement lamps, which are excluded from this category.

Exterior lighting

The following new measures have been added:

  • No controls
  • Basic or NLC
  • ANLC

All non-general illuminance will now be grouped in the non-prescriptive custom category.


See Tables Prescriptive Lighting System Retrofit Incentives and Small and Medium Business Express Incentives

Midstream incentives

This is the exclusive path for replacement lamps. As part of our program changes, the LED Instant Incentive and the existing post-purchase application are now replaced with the Express offering. Fixtures, kits, and controls will all be available downstream in the Express application or lighting tool.

The fullstream model of shared incentives is now combined into a midstream exclusive offer. Approved midstream trade allies may submit via single-sale log entries or via bulk uploads.


See Table Prescriptive Lighting System Retrofit Incentives

New Construction/Major Renovation

Most projects in this category include more than one system (e.g. lighting, HVAC or building envelope) and qualify for the Whole Building New Construction/Major Renovation offering.

If only a single system is changed, the project would fall into the following categories:

  • New construction incentives are available for most common building types lighting including Controlled Environmental Agriculture. For major renovation, lighting, HVAC, or building envelope is eligible for the incentives linked in the table below.

Exterior lighting

Single system new construction/major renovation exterior lighting incentives are changing to a tiered pay-for-savings structure where various incentive amounts per kilowatt hour apply based on the type of controls used:

  • No controls
  • Basic dimming controls
  • ANLC dimming controls


See Table New Construction/Major Renovation Lighting Incentives

Non-lighting incentives

The Green Motor Rewinds incentive is being removed from the program. 

See Table Motor Incentives 

TRANSITION PLAN:  

For projects requiring pre-approval see the table to understand which incentive applies.
For post-purchase projects, the earlier invoice date for the project is used to determine which tariff applies. 

 

Offer Letter dated prior to 9/24/25  We will use the program version in effect when the incentive offer letter was issued. 
Offer Letter dated from 9/24/25 to 10/23/25  Option to run on either incentive structure. 
Offer Letter dated 10/24/25 or later  New program with changes is in full effect.
