Managing a contemporary condominium resembles, in many respects, running a business, requiring the property manager and administration staff to adopt a strategic vision that goes beyond mere building maintenance. At the heart of the financial concerns, the electricity bill stands out as one of the most critical elements, not only because of its absolute value, but because of the uncertainty it casts over cash flow.

In a scenario where the average monthly rate paid by residents saw an increase of almost 25% in just three years the pursuit of savings has become an absolute priority to ensure the stability of collective accounts. This significant increase reflects structural changes in maintenance costs and in the national economic dynamic, putting pressure on the budgets of families living in the more than 327,000 active condominiums in Brazil.

The financial instability caused by a fluctuating electricity bill undermines the ability to plan for the long term. When the manager cannot accurately predict how much will be spent on energy the following month, building reserve funds or planning infrastructure improvements become reactive tasks, rather than proactive ones. Energy savings, therefore, should not be seen merely as a cost reduction, but as a pillar supporting the overall financial health of the development. For the property manager, mastering the nuances of electricity consumption and applying strategies that ensure cost stability is what distinguishes efficient management from merely procedural administration.

In this context, understanding the electricity bill as an expense that can be stabilised is the first step towards excellent financial organisation. Over the following sections, we will explore the savings mechanisms that managers and administrators can implement to shield the condominium against the volatility of the Brazilian energy market.

Outlook for 2026: inflationary pressure on the electricity bill

A condominium's budget planning must be guided by concrete data and realistic projections. For 2025 and 2026, estimates point to a continuation of the pressure on electricity tariffs. According to data from TR Soluções, the residential and condominium electricity bill will carry significant weight in inflation, with projected average increases of 11%, driven mainly by the cost of purchasing energy and by transmission system usage tariffs. For the property manager, this means the electricity bill will continue to be one of the items putting the most pressure on the IPCA, often exceeding the overall inflation forecast of 4.36% for the period.

The stability of condominium budgets is put to the test when consultancies and banks project that electricity could rise up to 8% above inflation in 2026. This phenomenon is driven by a combination of factors: low reservoir levels at hydroelectric plants, increased use of thermoelectric plants (which have a much higher generation cost), and the rise in subsidies built into tariffs, which are expected to reach R$47.8 billion in 2026. For administration staff, this data is essential for underpinning the annual budget forecast and justifying the need for investment in energy-saving measures before the general meeting.

The instability is compounded by the tariff flag system, which acts as a real-time price signal. During periods of water stress, the activation of the yellow or red flags can drastically increase the electricity bill from one month to the next, without any real increase in consumption having occurred. This volatility makes it harder to maintain financial stability, as it forces the condominium to deal with unforeseen expenses that can drain the reserve fund. Therefore, pursuing strategies that promote energy savings is not just an environmental choice, but a defence mechanism against an increasingly costly and unpredictable electricity system.

Financial organisation: separating fixed from variable expenses

Assertive financial management begins with clarity in classifying expenses. In the condominium environment, confusion between what constitutes a fixed expense and what is a variable expense is common. Fixed expenses are those essential to basic, recurring operations, such as payroll, security contracts, and the predictable portion of the common areas' electricity bill. Variable expenses, on the other hand, are those that fluctuate according to need, such as emergency repairs and occasional maintenance. Real savings emerge when the manager is able to identify which variable expenses can be optimised and which fixed expenses can be renegotiated to ensure greater cash-flow stability.

For the property manager, organising the chart of accounts in detail is essential to prevent the condominium from operating at its limit. The electricity bill, although dependent on consumption, must be monitored so that its fluctuations are understood and mitigated. When the manager uses control tools to forecast the spending ceiling, the electricity bill starts to behave like a fixed expense in the planning, reducing the need for constant adjustments to the condominium fee. This predictability is what ensures the stability needed for the administration to focus on improvements that add value to the property.

Implementing an efficient chart of accounts provides a 360-degree view of the finances. By categorising every real spent, administration staff can pinpoint precisely where savings are effective and where bottlenecks still exist. A condominium's financial stability is built on the foundation of transparency and rigorous control. Where energy is concerned, this means not only looking at the final amount on the bill, but breaking the electricity bill down into consumption, demand and charges, always seeking the best value for the community.

Lighting and presence sensors as pillars of savings

Among practical cost-reduction strategies, modernising the common areas' lighting system is the measure with the fastest return on investment. Replacing incandescent or fluorescent bulbs with LED technology can generate savings of up to 80% in that sector's energy consumption. Besides directly reducing the electricity bill, LED offers greater durability, meaning fewer replacement and maintenance costs, contributing to the stability of the building repair budget.

Installing presence sensors in areas of intermittent traffic, such as corridors, stairwells and car parks, is another essential strategy for any management seeking savings. Often, a condominium's electricity bill is inflated by lights left on all night in areas where no one is present. Sensors ensure energy is used only when needed, eliminating waste without compromising residents' safety. For the property manager, this is one of the measures that is easiest to get approved at a general meeting, thanks to the immediate visibility of the results.

The savings generated by intelligent lighting go beyond the financial; it shows residents that management is paying attention to detail. By automating the switching of lights, the manager removes the human factor (forgetfulness) from the equation, ensuring consumption stability is maintained month after month. It is advisable for administration staff to keep a historical record of consumption before and after these interventions, using this data to demonstrate the effectiveness of savings measures in accountability reports.

Motor efficiency: booster pumps and lifts

If lighting is the "visible face" of consumption, the motors of booster pumps and lifts are the great invisible consumers weighing on the electricity bill. Poorly sized water pumps or those with inadequate maintenance can run for far longer than necessary, generating excessive electricity consumption and jeopardising the stability of the water supply. Regular preventive maintenance is essential to ensure this equipment operates at maximum efficiency, avoiding energy leaks and premature wear of parts.

To raise the level of savings, the property manager should consider installing frequency inverters on the motors. This technology allows the motor to adjust its speed according to actual demand, eliminating the start-up peaks that are moments of high consumption on the electricity bill. Using inverters can reduce the energy consumption of this equipment by up to 30%, as well as extending its service life. For lifts, optimising the call system and encouraging residents to avoid unnecessary trips also contribute to overall savings and to the building's operational stability.

Modernising this equipment should be seen as a strategic investment. Although the initial cost may seem high, the monthly reduction in the electricity bill and the decrease in emergency corrective maintenance expenses ensure a financial return in the medium term. Administration staff play a crucial role in reviewing maintenance contracts and ensuring that service providers focus on energy efficiency, not just on the basic functionality of the equipment.

Conscious-use campaigns: the human factor in savings

Technology alone cannot ensure the stability of accounts without genuine engagement from the people involved. Awareness campaigns aimed at residents and staff are essential for savings measures to be sustainable over time. The property manager should promote environmental education not as a lecture, but as a mutually beneficial strategy: the less waste in common areas, the less pressure there is for increases in the electricity bill and, consequently, in the condominium fee.

Using visual materials in strategic areas, such as lifts and notice boards, helps keep the topic of savings visible. Simple tips, such as switching off lights when leaving function rooms or gyms and using the lift sensibly, may seem small individually, but they add up in a condominium with hundreds of residents. Furthermore, transparency in publicising the results of savings initiatives fosters a sense of community and pride among residents, who come to see themselves as part of the solution for the building's financial stability.

For staff, training should be more technical and focused on inspection routines. Caretakers and cleaning staff should be the first to spot burnt-out bulbs, leaks in pumps, or lights left on unnecessarily. Creating a culture in which resource savings is valued turns the team into a guardian of budget stability. Administration staff can support this process by creating routine checklists that include checking critical points of energy consumption.

Training and engagement of administrative and operational staff

The foundation of efficient management lies in training those who carry out the day-to-day tasks. For the property manager, investing in training the operational team — caretakers, doormen and cleaning staff — is one of the smartest ways to ensure energy savings. A well-trained employee does not just switch off a light left on; they understand how the correct operation of a gate motor or a pool pump affects the electricity bill and the financial stability of the entire condominium.

Workshops on energy efficiency and predictive maintenance can be organised by the administrator, bringing in specialists to guide staff on how to spot invisible waste. Engagement increases when employees realise their work contributes to the sustainability of the development and to reducing operating costs. In addition, setting consumption-reduction targets and rewarding teams that achieve them can be an excellent motivator for the everyday practice of saving energy.

Documenting maintenance processes and rigorously tracking consumption records allow management to build a solid history for decision-making. By analysing this data, administration staff can suggest adjustments to work routines that favour savings. A condominium's stability does not arise by chance, but from the coordinated effort of a team that understands the electricity bill is a resource to be managed with care and technical intelligence.

Auditing invoices and identifying improper charges

An aspect frequently overlooked in managing the electricity bill is the thorough review of amounts charged by utility companies. Reading errors, incorrect tariff application, or charges for services not contracted can improperly inflate the monthly cost, harming the condominium's financial stability. The property manager, supported by administration staff, should carry out periodic audits of invoices to ensure the condominium pays only for what it actually consumed.

Technical issues such as contracted demand and excess reactive energy are critical points for large condominiums. If demand is poorly sized, the condominium may be paying for availability it does not use or, worse, facing fines for exceeding demand, which throws off any savings plan. Analysing these items requires a specialised eye, but the results in terms of budget stability are immediate. Identifying and disputing these errors with the utility company is a fiduciary duty of the manager.

The ANEEL's Resolution 1000 guarantees consumers the right to dispute amounts and request meter inspections in cases of suspected irregularity. If an improper charge is proven, the condominium may be entitled to a refund of double the amount overpaid, which represents a significant boost of funds for the reserve. Thus, auditing the electricity bill becomes a tool for asset protection, ensuring the intended savings are not undone by the utility company's administrative errors.

Property value and sustainability as a market differentiator

Adopting savings measures and clean energy sources brings more than immediate financial benefits; it adds value to the property on the real estate market. Research indicates that units in buildings that invest in sustainability and energy efficiency can achieve value increases of up to 30% compared with conventional buildings. In 2025, having solar energy systems or energy subscription solutions became one of the main criteria for buyers seeking a lower cost of living and environmental responsibility.

For the property manager, presenting the condominium as an efficient and sustainable structure is a way to attract better residents and increase the value of residents' property. A building that demonstrates stable fees thanks to smart energy management is far more appealing to investors. Moreover, ESG practices (Environmental, Social and Governance) are increasingly on the radar of administrators, who seek to modernise their portfolios with solutions that combine savings with the preservation of natural resources.

Sustainability, therefore, ceases to be an abstract concept and becomes a tangible financial asset. When the electricity bill is reduced through conscious practices and strategic partnerships, the condominium becomes a model of efficiency. This positive perception is directly reflected in how easily units can be sold or let, ensuring that the investment in energy savings pays back to the owner in various ways over time.

The Distributed Generation Legal Framework and approval quorums

Legal certainty for implementing energy projects in condominiums was established with Law 14,300/2022, known as the Distributed Generation Legal Framework. This legislation sets out the rules for offsetting energy credits, ensuring that savings investments made today have legal validity and regulatory stability for decades to come. For the manager, it is essential to know the quorum rules so that decisions made at general meetings are legally valid and not subject to future challenges.

For the physical installation of solar systems, which alter common areas, the quorum generally required is an absolute majority (50% + 1 of all residents), as it is considered a "useful improvement" that brings direct financial benefits to the building. However, for joining clean energy subscription contracts, such as NewSun's, since it is a service agreement aimed at reducing ordinary expenses (similar to a phone or maintenance contract), approval can often be decided by a simple majority of those present at the meeting, depending on the by-laws.

It is essential for the property manager and administration staff to prepare a robust presentation, focused on the benefits of savings and stability, to address doubts and secure residents' buy-in. Clarity on the legal aspects and adherence to the legal quorums prevent conflicts and ensure the transition to a more efficient energy model happens smoothly and safely for everyone involved.

The path to high-performance condominium management

Turning the electricity bill into a fixed, predictable expense is one of the greatest legacies a property manager can leave for their management. Through a combination of technical savings measures, people engagement and the adoption of innovative technologies such as the NewSun Energy Group energy subscription, it is possible to achieve a level of financial stability that seemed unattainable years ago. The modern manager can no longer accept tariff volatility as an inevitable fate; they now have the tools needed to shield the condominium and ensure residents' resources are applied with intelligence and sustainability.

Financial organisation, guided by a rigorous chart of accounts and constant invoice audits, creates a solid foundation for growth and the appreciation of the property. By investing in training and awareness campaigns, the condominium strengthens its social fabric, building a community that values savings and environmental preservation. The journey towards energy efficiency is ongoing, but the results in terms of stability, reduced default rates and property appreciation make every effort worthwhile.

High-performance condominium management requires proactivity and the use of data for decision-making. By focusing on stability and energy savings, the manager not only reduces expenses but builds a more resilient environment, ready for the economic challenges ahead. The electricity bill, once a villain, becomes an ally of good management when handled with the right strategies.
