Funding Energy Upgrades in 2026: CapEx, OpEx, and Incentives Explained

By Monte Hartranft, VP of Sales for Evolved Lighting & Energy

 

For facility leaders and property managers, energy projects often start with a simple goal. Reduce energy costs. Improve reliability. Modernize aging systems.
But the real challenge usually is not the technology. It is funding.

In 2026, organizations are balancing tighter capital budgets, rising operating costs, and a rapidly changing incentive landscape. Understanding the difference between CapEx and OpEx funding and how incentives interact with both can make the difference between a stalled project and one that moves forward quickly.

This guide breaks down how facilities and finance teams can approach energy upgrades strategically in today’s market.

Understanding CapEx vs OpEx for Energy Projects

Capital expenditures (CapEx) and operating expenses (OpEx) represent two different ways organizations pay for improvements.

CapEx typically covers major assets that provide long term value. Examples include lighting retrofits, HVAC replacements, building automation systems, or electrical infrastructure upgrades. These investments are capitalized and depreciated over time.

OpEx covers ongoing costs required to operate a facility. This includes energy consumption, maintenance, service contracts, and operational labor.

For energy efficiency projects, the decision often comes down to how organizations want to structure cash flow.

CapEx approach

• Organization funds the project upfront
• Equipment becomes a capital asset
• Savings reduce operating expenses over time
• Depreciation and tax deductions may apply

OpEx approach

• Costs are spread over time through service agreements, financing, or energy performance contracts
• No large upfront capital request
• Savings offset the ongoing payment

Many organizations now blend these approaches. Some equipment is purchased through capital budgets while controls, software, or performance contracts fall into operational budgets.

Why Energy Projects Are Gaining Attention in 2026

Energy has become a larger share of operating costs for many commercial facilities. Electricity prices and demand charges have increased in many regions, and aging infrastructure is becoming more expensive to maintain.

Energy efficiency projects remain one of the most reliable ways to reduce operating costs while improving building performance.

Lighting upgrades continue to deliver some of the fastest returns. LED retrofits can reduce lighting energy consumption by 50 to 75 percent while improving light quality and reducing maintenance requirements. Typical payback periods often fall between 18 and 30 months depending on incentives and operating hours.

These economics make lighting and controls upgrades especially attractive for facilities teams looking for quick operational savings.

At the same time, organizations are increasingly evaluating lifecycle cost instead of simply initial price. While advanced controls or smart building technologies may increase upfront CapEx by roughly 10 to 15 percent, they can reduce lighting operating costs by 20 to 35 percent annually through occupancy control and automated scheduling.

In other words, the most effective projects balance capital investment with long term operational savings.

The Role of Incentives in Project Funding

One of the most important drivers for energy projects in 2026 is incentives.

Utility programs, tax deductions, and state programs can significantly reduce project cost and accelerate approval. In some cases, incentives can cover 30 to 50 percent of total project cost depending on the utility program and energy savings achieved.

For facilities in Ohio, this is particularly relevant. Programs offered by utilities such as AEP Ohio, Duke Energy Ohio, and FirstEnergy provide prescriptive and custom rebates for upgrades including:

• LED lighting retrofits
• HVAC improvements
• motors and variable frequency drives
• refrigeration systems
• advanced controls

Lighting incentives alone can reach approximately $0.50 to $2.00 per watt reduced depending on the program and technology used.

These incentives directly reduce project CapEx, which can dramatically improve ROI and shorten payback periods.

Federal incentives also remain a key component of the funding strategy. The Section 179D energy efficient commercial buildings deduction allows building owners to claim deductions based on building square footage for qualifying upgrades including lighting, HVAC, and envelope improvements. In some cases, this can reach up to $5 per square foot of building space.

However, many federal provisions are scheduled to change in mid 2026, making early planning important for organizations that want to maximize available tax benefits.

How Incentives Influence CapEx vs OpEx Decisions

Incentives can change the financial structure of a project in meaningful ways.

When incentives significantly reduce project cost, organizations may choose a CapEx model because the payback period becomes very attractive.

For example,

A lighting retrofit that originally costs $300,000 may receive utility rebates and tax incentives that reduce the net cost by 30 to 40 percent. That reduction may shift a project from a five-year payback to closer to three years.

When that happens, capital approval often becomes easier because the return on investment is clear and measurable.

In other cases, organizations use incentives to reduce financing costs within an OpEx model. Rebates and tax deductions can lower the financed amount and improve cash flow from day one.

Strategies for Getting Energy Projects Approved

Even with strong financial returns, many energy projects stall during internal approval. Facilities teams often compete with production investments, technology upgrades, and other capital priorities.

Successful projects usually share a few common elements.

1. Lead with operational impact
   Finance leaders want to understand how the project improves operating costs. Demonstrating measurable reductions in energy, maintenance, and downtime helps justify the investment.
2. Use lifecycle cost analysis
   Instead of focusing only on upfront cost, present the full financial picture. Include energy savings, maintenance reductions, and avoided equipment failures.
3. Quantify incentives early
   Incentives should be included in the financial model from the beginning. Pre-approval from utilities often strengthens the business case and reduces financial uncertainty.
4. Bundle projects when possible
   Combining lighting, controls, and mechanical upgrades can improve incentive eligibility and increase overall savings.
5. Partner with experienced contractors
   Projects move faster when contractors understand incentive requirements, documentation, and engineering calculations. Many utilities require pre-approval and detailed savings documentation.

The Opportunity for Facilities Teams

Energy upgrades are no longer just sustainability initiatives. They are financial and operational strategies.

For facilities and operations professionals, this creates an opportunity to lead projects that improve building performance while reducing operating expenses. For finance teams, these projects represent measurable returns in an environment where cost control matters more than ever.

The key is understanding how funding structures, incentives, and long-term savings work together.

Organizations that take a proactive approach in 2026 can capture available incentives, modernize aging infrastructure, and create facilities that operate more efficiently for years to come.
