Smart Metering: reliable energy data, automatically
Smart metering turns energy consumption into reliable, digital data. It replaces manual readings with automated data transfer and gives building owners and operators a clear view of how their properties use energy.

Smart metering makes energy data available where it is needed
Energy data is only as good as the way it is collected. Annual invoices, manual readings and estimates leave gaps: values arrive late, cover long periods and rarely match the level at which decisions are made, such as the individual building, system or tenant. Smart metering closes these gaps. Digital meters capture consumption in short intervals, transmit it automatically and deliver it in a consistent format, regardless of who would have read the meter and when.
This makes smart metering the enabler for everything that builds on energy data: monitoring, cost allocation, emissions and ESG reporting, and energy management. Each of them needs figures that are traceable, current and comparable across sites. Without a digital metering layer, they depend on manual effort and on reconstructing consumption after the fact. With it, the data is there while consumption happens. It also prepares buildings for what follows, from flexible tariffs and on-site generation to an energy system with a growing share of renewables that relies on precise information about when and where energy is used.
Meters — accurate measurement
Digital meters record consumption in short intervals instead of a single annual value. Depending on the property, this covers electricity and gas, and in many countries also water and heat. The resulting data is far more detailed than a conventional reading and shows how consumption develops over the day, the week and the season.
Communication — secure transfer
The values are transmitted automatically, so nobody has to visit the site. Depending on the building and on national requirements, transmission runs over wireless networks, wired connections such as M-Bus, or a combination of both. Data is encrypted in transit and reaches only authorised recipients. Requirements for security and data protection are set nationally and are followed by ista in each country.
Platform — data in one place
On a platform such as MinuteView, the data appears as graphs and tables per meter, building or site. Thresholds can trigger alerts, comparisons show where a site deviates from others, and data can be exported for use in other systems. The figures reach the people who operate the building, not just those who produce the annual report.
What a smart metering project involves
The scope of services ista offers varies by country. In principle, a project runs through these stages.
Assessment and metering concept
What needs to be measured determines what has to be installed. A metering concept defines the measuring points, the energy carriers and the way the data is transmitted, based on the building's structure and technical infrastructure.
Installation and commissioning
The devices are installed, connected and put into operation. For larger portfolios, the rollout is coordinated across sites so that buildings are digitalised in a structured sequence.
Operation and data provision
Once running, data is collected automatically, checked for plausibility and made available on the platform. Data quality is monitored continuously, because a reading that arrives late or not at all is the most common reason a report cannot be produced on time.
Benefits
What smart metering does for a portfolio
- check
Less manual effort: Automated readings remove appointments, estimates and reading errors.
- check
Transparency: Consumption is visible per meter, building and site, without waiting for the year-end invoice.
- check
Reporting without reconstruction: Sustainability disclosure draws on data collected as it arose, not assembled after the fact.
- check
Comparability across the portfolio: Benchmarking shows which buildings deserve investment first, rather than spreading budget evenly.
- check
Comparability: Consistent data across sites shows which buildings deserve attention first.
ista worldwide — smart metering in your country
Smart metering is part of our portfolio in selected markets. Where it is available, the metering technology, the regulatory framework and the services differ, because building stock, market structures and national law differ. The country websites describe what we offer locally, in the local language, and who to speak to.
