Comparing Sites, Years and Meters: Expertpower's Advanced Energy Comparison Reporting
A single site’s energy bill tells you what one building used last month. It does not tell you whether that number is good, bad or ordinary. It says nothing about the other nine sites in the portfolio.
Real insight only shows up when performance can be lined up side by side. That means against last year and against the sites down the road. Most energy reporting is simply not built to do this.
Expertpower’s advanced comparison wizard was built for this gap. A user can select multiple devices, multiple parameters and multiple time periods together in a single view, instead of opening one report per site or per meter.
For a portfolio manager, that turns twelve separate monthly reviews into one comparison. It turns a hunch about an underperforming site into a number that can be acted on.
Key Points
- Comparing energy performance across a portfolio has traditionally meant exporting spreadsheets from separate systems then reconciling them by hand.
- Expertpower’s advanced comparison wizard lets a user select multiple meters, parameters and time periods in one screen rather than one report at a time.
- Year-on-year cumulative consumption comparisons reveal genuine trends that a single month’s bill cannot show on its own.
- Viewing a portfolio side by side surfaces the one underperforming site or circuit before it turns into an expensive surprise.
- Comparison reports export to HTML, Microsoft Excel or PDF and can run manually, automatically or on a set schedule.
- None of this comparison is worth anything if the underlying meter data is not accurate and consistent to begin with. That is where SATEC’s hardware does the groundwork.
Why One Number Never Tells the Whole Story
Multi-site organisations tend to hit the same wall. A retail chain, a university with several campuses, a council managing several public facilities and a landlord running an embedded network all produce the same problem: each site generates its own bill, its own meter reads and its own set of numbers.
None of those numbers are naturally comparable on their own. A sharp rise at one site might be a genuine problem. It might just as easily be a seasonal blip. Without a second site or a prior year to compare it against, there is simply no way to tell which.
That is the exact gap Expertpower’s energy management software was built to close.
Multiple Sites, Multiple Years, One View
Expertpower’s comparison wizard addresses this directly. Several devices, parameters and time periods can be selected and viewed together in one screen. A facilities manager can put three sites’ after-hours consumption side by side over the same twelve months.
They can just as easily compare one site’s performance this year against last year, without exporting anything or building a spreadsheet from scratch.
Expertpower collects data from SATEC and other metering devices over standard protocols including Modbus, BACnet, DLMS and SNMP. This means a mixed fleet of meters across different sites can still be brought into the one comparison. There is no need for every site to run identical hardware first.
The year-on-year angle matters just as much as the cross-site one. Expertpower’s efficiency reporting includes a cumulative comparison of monthly consumption against previous years. A genuine downward or upward trend becomes visible instead of being assumed.
That is a different question from asking whether one site used more energy than another. It is the question that actually tells a business whether an efficiency initiative is working. It is also the question that reveals whether last year’s saving has quietly crept back.
Turning Comparisons Into Reports People Can Use
None of this is useful if it stays locked inside a dashboard nobody else sees. Comparison reports in Expertpower can be generated manually, automatically or on a schedule. They export straight to HTML, Excel or PDF.
A comparison built once for a board pack or a tenant review becomes a report that can simply be reused each cycle. There is no need to rebuild it from scratch every time the numbers are due
How SATEC Fits Into the Picture
Comparison reporting is only as good as the data feeding it. That is the part hardware has to get right before software can do anything useful with it.
SATEC’s meters are built to deliver the accurate, granular readings a fair comparison depends on. This holds whether the job is a single circuit inside one building or dozens of sites spread across a state.
Consistency between sites matters here too. A comparison is only meaningful when every site is measured to the same standard rather than a mix of accurate and approximate readings. Sites that grow over time are also worth planning for.
Expertpower’s architecture scales from a single device to tens of thousands of devices without the reporting approach needing to change. Portfolio growth, in other words, does not mean starting the comparison process over from scratch.
Monthly Billing Review vs Expertpower Comparison Reporting
| Aspect | Monthly Billing Review | Expertpower Comparison Reporting |
|---|---|---|
| Data granularity | Monthly total only | Interval data down to the meter and circuit |
| Cross-site visibility | Site by site, combined manually | Multiple sites and meters in one wizard view |
| Year-on-year tracking | Manual spreadsheet work | Built-in cumulative comparison against prior years |
| Report format | Static PDF or paper invoice | Scheduled or on-demand HTML, Excel or PDF |
| Effort to compare | Hours per reporting cycle | Minutes once the comparison is configured |
| Scalability | Gets harder as the portfolio grows | Scales from one meter to tens of thousands |

FAQs - Comparing Sites, Years and Meters
-
What does Expertpower's comparison wizard actually let me compare?
It lets you select multiple devices, parameters and time periods together. Several meters or sites can be viewed side by side instead of one report at a time, mixing and matching by site, by circuit or by period depending on what the question actually is.
-
Can I compare this year's consumption with last year's?
Yes. Expertpower's efficiency reporting includes a cumulative comparison against previous years. A genuine year-on-year trend is visible rather than assumed from a single month's bill.
-
Does comparison reporting still work if my sites use different meter models?
Expertpower collects data from SATEC and other devices over standard protocols including Modbus, BACnet, DLMS and SNMP. A mixed fleet across sites can still be brought into one comparison view, though the accuracy of that comparison still depends on every meter being properly specified for the job it is doing.
-
How do I share comparison data with finance or the board?
Reports can be generated manually, automatically or on a set schedule and exported to HTML, Microsoft Excel or PDF. A comparison built once can be reused as a recurring report rather than rebuilt from scratch every cycle.
