Energy Audit for a Company: The Path to Cost Optimization and Energy Efficiency

Starting in April 2026, the electricity transmission tariff in Ukraine will rise to 742.91 UAH/MWh —this is the second increase this year. For businesses that pay 6–9 UAH per kilowatt-hour, every percentage point of increase translates into significant amounts on their monthly bills. An energy audit is a tool that reveals where money is being wasted: according to Ukrainian energy audit firms, businesses reduce their energy costs by 10–30% following an audit. Let’s break down how an audit works, how much it costs, and how quickly it pays for itself.

What Is an Energy Audit for a Business?

When electricity bills rise faster than revenue, business owners start looking for the cause. An energy audit is exactly the tool that turns guesswork into precise figures: a comprehensive assessment of the facility reveals how much energy each system consumes, where losses occur, and what measures will yield real savings.

The State Agency for Energy Efficiency defines an energy audit as an activity aimed at reducing energy consumption by improving energy efficiency. It differs from a routine technical inspection of equipment in its systematic approach: the auditor analyzes not a single machine or boiler, but the entire energy infrastructure—from the point of electricity supply to the end user. The methodology is governed by the international standard ISO 50002:2025, which provides for three levels of detail—ranging from a quick review of documentation to a comprehensive instrumental survey with a technical and economic justification for each measure.

As a result, the owner receives not just abstract recommendations such as “save electricity,” but a list of actions with a calculation of the implementation cost and payback period—in effect, a set of priorities for investments in energy efficiency.

Why Should Businesses Conduct an Energy Audit?

A company with a monthly electricity bill of 500,000 UAH saves up to 1.8 million UAH per year after implementing the audit’s recommendations. These savings result from dozens of specific measures:

• Switching to LED lighting reduces electricity costs for lighting by 60–80%;
• Installing frequency converters on electric motors reduces their energy consumption by 7–60%, depending on the operating mode;
• Optimizing energy consumption in ventilation and air conditioning systems can result in savings of up to 40%.

In addition to direct savings, an energy audit provides access to financial instruments. Ukraine’s Law “On Energy Efficiency” requires large enterprises to conduct an energy audit once every four years—or to implement an energy management system in accordance with ISO 50001. For small and medium-sized businesses, the procedure is voluntary, but without a report, it is difficult to obtain a loan for energy-efficient equipment or a grant from international programs.

Energy audits of industrial facilities also reveal hidden losses—for example, a low power factor, which results in penalties from the utility provider and causes equipment to overheat and wear out more quickly. Reactive power compensation simultaneously reduces utility bills and extends the service life of equipment.

Types of Energy Audits for Businesses

The ISO 50002 standard distinguishes between three types of energy audits, and the choice depends on the size of the organization and the objectives set by the owner.

An express energy audit is suitable when you need to quickly determine whether there is potential for savings—and whether it’s worth investing in a full-scale assessment. A standard audit provides enough data to make decisions about replacing equipment or modernizing systems. A comprehensive audit is necessary if a company is planning a large-scale renovation or wants to secure external financing: banks and grant programs require a detailed feasibility study with a payback analysis.

How an Energy Audit Is Conducted: Key Steps

So, how is an energy audit conducted? Once the type of audit has been selected, the work is divided into four sequential stages—each of which lays the groundwork for the next.

Stage 1. Document Review

The auditor begins with desk work: meeting with management, determining the specifics of production, and gathering primary documentation—energy bills for the past 12–36 months, contracts with suppliers, electrical diagrams, and technical documentation for equipment. This provides a preliminary picture of energy consumption and identifies areas for a detailed audit.

Phase 2. Technical Survey

Next, the auditor proceeds to the site. Using thermal imagers, power quality analyzers, and flow meters, he records the actual operating parameters of each system. A thermographic inspection identifies heat loss through building envelopes, insulation defects, and abnormally hot electrical connections.

Phase 3. Analysis and Development of Measures

The auditor compiles the collected data into energy balances—tables that show how much energy enters the facility, how it is distributed among the systems, and where losses occur. Based on these balances, a list of energy-saving measures is developed, complete with a technical and economic justification: implementation cost, projected savings, and payback period.

Step 4. Preparing the report

The auditor compiles the results into a structured document: the company’s energy passport, a description of the identified issues, and an action plan with financial projections. The measures are ranked by priority—from those that will pay for themselves within months to large-scale modernization projects.

Who is authorized to conduct an energy audit

The quality of an audit depends directly on the auditor’s qualifications. In Ukraine, energy audits are conducted by certified specialists, whose qualifications are determined by the Ukrainian Association of Energy Auditors through a voluntary certification system.

The minimum qualification requirements depend on your education:

• A specialist or master’s degree holder with relevant education—at least 3 years of experience, 2 completed energy audit reports, and 2 letters of recommendation from clients;
• Bachelor’s degree in a relevant field — 5 years of experience, 3 reports, 3 letters of recommendation;
• Without a degree in the field — 10 years of experience, 5 reports, 5 letters of recommendation.

Certification requires passing a 40-question exam (passing score: 70%) and is valid for 5 years. The association maintains a registry of auditors used by banks and clients. A report from a non-certified specialist may be rejected by the regulator or a bank, so before signing a contract, verify that the service provider is listed in the registry.

What Is Included in an Energy Audit Report

The entire audit process is summarized in a single document—the energy audit report. Its structure is defined by the standard, while its content depends on the specific characteristics of the enterprise.

A typical report includes:

• a description of the company’s energy infrastructure—a list of systems, equipment, and energy sources;
• energy balances — breakdown of consumption by systems and processes, identified losses;
• results of instrumental measurements—actual equipment performance indicators compared to standard values;
• a list of recommended measures—each with a breakdown of implementation costs, projected savings, and payback period;
• An enterprise’s energy passport is a consolidated document containing key energy efficiency indicators.

A separate section covers the share of energy costs in the cost of production. This metric allows a company to compare itself against industry benchmarks and understand the extent to which its energy efficiency affects its competitiveness.

How much does an energy audit cost, and how quickly does it pay for itself?

The cost of an audit depends on the type of business, its size, and the level of detail selected. For an industrial facility with an area of 5,000 m², a comprehensive energy audit costs between 50,000 and 150,000 hryvnias. Commercial buildings—offices, warehouses, and retail spaces—are less expensive, starting at 30,000 UAH. If only thermography is needed (for example, to check insulation or locate heat leaks), such an inspection costs 3,000–8,000 UAH.

These investments pay for themselves in 3–6 months. A company with a monthly bill of 200,000 UAH that reduces its consumption by 15% following an audit will save 360,000 UAH per year—twice the cost of the audit itself.

Implementing these recommendations requires significantly greater investment—replacing lighting, installing frequency converters, and compensating for reactive power. This is where we at eDilo help businesses: our installment payment service allows you to purchase equipment for energy retrofits without a one-time drain on working capital.

In 2026, the “Affordable Loans 5–7–9%” program was expanded to include business energy independence, and a one-time grant of up to 15,000 UAH was introduced for sole proprietors to fund energy resilience measures. In total, the 2026 budget allocates 51.8 billion UAH to support businesses. To participate in most programs, banks and grant providers specifically require an energy audit report—applications without a verified feasibility study will not be considered.

An energy audit is the first practical step toward reducing energy costs and improving a business’s competitiveness. It identifies exactly where a company is losing money and provides a clear action plan with specific payback figures. With utility rates set to rise in 2026, every month of delay becomes increasingly costly—the sooner a business conducts an audit, the sooner it will start saving money.

And to implement these recommendations—from new lighting to industrial equipment—use eDilo. Our installment payment service will help you get started on your modernization without putting an undue strain on your budget.
