HUF 5.8 Million Annual Saving Potential Without Investment
OMS24 Zrt. analysed the electricity bills and related data of 15 consumption sites within a nationwide property management portfolio to determine whether any cost components were disproportionately high compared with actual operational requirements.
The result of the analysis was clear:
optimising the contracted capacity levels revealed an annual net saving potential of HUF 5,755,397.
This represented a 23% potential reduction in contracted capacity charges across the portfolio analysed.
Importantly, this result did not come from an investment aimed at reducing energy consumption.
It came from setting the contracted capacity levels correctly.
The starting point
In larger property portfolios, electricity demand and operating characteristics at individual sites often change over time, while contractual capacity settings may remain unchanged for years.
This can lead to two different problems:
contracted capacity may be too high, resulting in unnecessarily high network-use charges;
or it may be too low, creating operational and billing risks.
The objective was therefore not simply to reduce contracted capacity.
It was to determine the appropriate capacity level for each site based on actual operating conditions.
What did we analyse?
The assessment was based on:
electricity bills;
contracted capacity data;
and, where available, interval consumption data.
The aim was to determine for each site:
whether the existing contracted capacity was appropriate;
whether it should be reduced or increased;
whether there were any additional technical or operational anomalies worth investigating;
and whether there were any reactive power management issues.
What did the analysis reveal?
The aggregated figures speak for themselves:
Original annual contracted capacity charges: HUF 24,687,949
Identified annual saving potential: HUF 5,755,397
Potential saving: 23%
Average potential saving per site: HUF 383,693/year
This means that reviewing the contracted capacity levels alone revealed a significant opportunity to reduce costs across the portfolio.
Another important finding was that the correct solution was not the same at every site.
Of the 15 consumption sites:
several required a reduction in contracted capacity;
while at some locations we actually recommended an increase in contracted capacity, because the available data indicated that the existing level was not sufficiently aligned with actual operating requirements.
This demonstrates that the objective is not to reduce capacity at all costs.
It is to optimise it based on actual operation.
What specific recommendations were made?
A separate recommendation was prepared for each individual site.
In most cases, the required action was to modify the contracted capacity, for example:
reduce to 84 kW;
reduce to 72 kW;
reduce to 57 kW;
reduce to 30 kW;
while at other sites, increases such as:
increase to 88 kW;
increase to 135 kW;
increase to 80 kW
were considered appropriate.
In addition to the capacity recommendations, further actions were identified at several sites, including:
inspection of power factor correction equipment;
investigation of operational anomalies.
The analysis therefore identified not only opportunities for cost reduction, but also areas where operation could be further improved.
A closer look at the analysis
1. Overview assessment matrix
The table below summarises the data available at each of the 15 sites and shows where deviations or areas requiring further investigation were identified.
It demonstrates the underlying logic of the analysis: electricity bills, interval data, contracted capacity, reactive power conditions and operational anomalies were evaluated together.

2. Savings summary
The second table shows, for each individual site:
the original contracted capacity charge;
the saving potential identified by the analysis;
and the corresponding percentage reduction.
It clearly shows that the level of potential savings varied from site to site, while the combined opportunity across the portfolio was significant.

3. Recommended actions
The third figure shows not only the outcome of the analysis, but also the specific actions recommended for the individual sites.
This demonstrates that optimisation is not based on a standardised decision applied everywhere.
Each site requires a targeted recommendation based on its own operating data.

4. Power demand profile
The power demand profile shows how actual active power demand compares with the existing contracted capacity.
These profiles help determine whether the current contractual value is:
too high;
too low;
or appropriately set.
This is where electricity bill analysis becomes more than an administrative exercise and gains real technical depth.

5. Overall results
The final figure provides a clear summary of the overall result:
the current annual cost level;
the proposed optimised state;
and the potential difference between them.
Together, these figures show an identified annual net saving potential of approximately:
HUF 5.8 million.

What was the most important lesson?
This case study demonstrates that energy costs are not reduced only by lowering consumption.
In many cases, significant results can already be achieved by reviewing:
electricity bills;
contracted capacity levels;
and the actual operating data behind them.
Correctly configured contracted capacity can reduce operating costs without compromising operational reliability.
Contracted capacity is not an absolute ceiling that can never be exceeded or changed in the future.
By intelligently aligning actual power demand with contracted capacity, significant annual savings may be achievable without any technical investment — sometimes with little more than a few administrative changes.
Summary
Based on the analysis of the 15 consumption sites, OMS24 Zrt. identified that:
optimising contracted capacity could have delivered approximately HUF 5.8 million in annual net savings.
This represented:
23% cost-saving potential;
no technical investment requirement;
and savings arising solely from optimisation of contracted capacity.
For this reason, one of the first steps in reducing electricity costs is often not a new energy-efficiency investment.
It is a thorough analysis of the company’s existing electricity bills, contracts and actual operating data.
