A monthly energy report shows consumption, maximum demand, power factor and savings against an agreed baseline, then explains what changed and what to approve next. Pull the readings, tariff lines and peak demand figures from meters and the utility bill without retyping, and keep your own hours for the written explanation. The client reads the explanation.
Start with what the client must decide
Your reader is a plant manager. Forty charts would lose them, so the report has to say whether the bill is falling, why one number moved and what needs a signature this month.
Open with three lines. The first compares consumption with last month and the baseline, the second compares peak demand with the contract limit, and the third names one action with an owner.
If it needs a call, rewrite it. A finance head reading on a phone between meetings should reach the decision before the second scroll, and an engineer should find the meter table one page later.
The four measures every report needs
Consumption in kilowatt hours comes first, split by meter, shift or area wherever sub-meters exist and by tariff band wherever the bill separates peak from off-peak hours.
Maximum demand follows, in kVA or kW, with the date and the half hour it occurred, then power factor as an average and a lowest reading. Savings against baseline come last. Adjust them for production or weather.
Baselines go wrong first. State how it was set, over which months, and which factors it was adjusted for, because a saving quoted without a baseline is only a claim. Add the utility bill lines beside the meter figures, including billed demand, the power factor penalty or incentive and the tariff slab, so any mismatch shows first. Disagreements deserve an explanation.
- Consumption by meter, area or shift
- Peak demand with date and time
- Average and lowest power factor
- Savings against the adjusted baseline
- Tariff slab or time-of-day split
Explain the peaks and the penalties
A demand peak has a cause. Say which compressors, furnaces or chillers started together at seven in the morning, and read it from the half-hourly load profile instead of guessing afterwards.
Power factor deserves the same care. A dip below the utility’s threshold can bring a penalty, and a failed capacitor bank is a common reason, so name the feeder and the day.
Flag anything the meters cannot explain and mark it as a question for the site team, because an honest gap earns more trust than a confident guess. Unexplained loads get a question mark.
What to pull from meters and what to write
Interval data, daily totals, peak demand, power factor and the baseline comparison should arrive from the meters, the data logger or the energy platform without anyone retyping them. Retyping is where transposed digits start.
Keep the commentary human. Each site gets a short note covering causes found, actions already taken and actions proposed, and a template with fixed headings lets the analyst write it in minutes.
Send the same layout every month. Clients learn where to look, and the analyst spends the saved hours on exceptions such as a missing meter reading or a tripped capacitor stage instead of formatting.
- Automatic: interval data, totals, peaks, power factor, baseline
- Semi-automatic: utility bill lines and tariff checks
- Manual: cause notes, actions and next month’s plan
Build it in this order
Fix one client first. Settle the four measures and the baseline with them, build the page in a spreadsheet or reporting tool, and run it for two months beside the old method.
Check every figure against the utility bill and, where meter data is missing, mark the gap rather than filling it with an estimate nobody asked for.
Only then copy the layout across. Each new site then costs an hour of mapping meters to the template, where the first one needed careful work on the baseline and the layout.
Monthly energy report template
A two-page template. Page one holds the three-line summary, a strip showing consumption, peak demand, power factor and savings, and an action list with an owner and due date. Page two carries a table by meter with kWh, peak kVA and date, a half-hourly load profile for the peak day, the baseline method note, a bill reconciliation block.

How long should a monthly energy report be?
Two pages serve most clients. Give decision makers a summary page and give the analyst, the auditor and the engineer a detail page with the meter table behind every figure on the first.
How do I set a fair baseline?
Choose a stable earlier period. Adjust it for production, weather or occupancy, write the method on the report itself, and agree both with the client before any saving is claimed.
Which numbers can be automated safely?
Automate anything that arrives straight from a meter, a logger or a bill, such as interval data, totals, peaks and tariff lines. Cause notes and recommended actions need a person who knows the site, its shift pattern and the machines that start together each morning.
What if meter data is missing for some days?
Show the gap and state how many hours of interval data are missing, then mark any estimate clearly, because a hidden estimate can distort the savings figure. Never fill it silently.
