PROPOSED PROJECT
Tariff Bill Checker
Help energy managers check bills across several sites against agreed rates and meter readings. Read billing dates and charges, recalculate the amounts, and prepare a report of differences linked to the original records for review with the provider.
The meter agrees. The rate does not.

behind the total.
Two fictional site bills cover the same 30-day period. Site A uses 6,000 kWh at an agreed 0.18 currency units per kWh plus a 40-unit fixed charge, but its invoice uses 0.20. Site B uses 4,000 kWh at 0.21 plus 40 and matches. The checked totals are 2,000 expected and 2,120 billed, leaving a 120-unit rate difference for review. This simplified example excludes taxes, demand charges, and other tariff components.
WHAT IS USUALLY DONE
An energy manager compares several bills with contract PDFs and meter spreadsheets. A changed unit price can be missed when the overall total looks plausible. Different billing dates, meter multipliers, or extra charges can make a simple arithmetic comparison misleading.
WHAT SOVRUN CAN DO FOR YOU
Sovrun would build a bill review that reads designated bill and contract versions, aligns billing periods with meter records, and recalculates the supported charges. Each difference links to its original rate, reading, and invoice line. Unsupported charges and unclear terms stay in a review queue, ready for an energy manager to discuss with the supplier.
Same consumption.
Two different unit prices.
Site A’s meter moves from 10,000 to 16,000 kWh, with a multiplier of one. The agreed rate is 0.18 per kWh, but invoice I-A uses 0.20. The 40-unit fixed charge matches in both records.
0.18 per kWh
6,000 × 0.18 + 40
1,120 expected0.20 per kWh
6,000 × 0.20 + 40
1,240 billedPlease confirm why Site A uses 0.20 per kWh for this period when the supplied agreement lists 0.18. The resulting difference is 120 example currency units. Please provide any applicable rate-change record.
A recalculation you can follow.
A question backed by records.
The first build checks an agreed set of charge types across selected sites. Missing terms stay unresolved, and the energy manager approves any communication or payment decision.

How we’d make it happen.
Read and confirm the billing inputs
Extract candidate fields from the designated documents. Review site IDs, periods, meter factors, and rates before calculating.
Recalculate supported charges
Compute consumption and agreed charges using the supplied rounding rules. Keep missing or ambiguous components outside the verified total.
Prepare the evidence for review
Link each difference to its original records. The energy manager approves any question to the supplier and tracks the response separately.
Where AI helps
Document models extract candidate dates, rates, and charge fields. Deterministic calculations recompute amounts from reviewed inputs. Language models draft a concise explanation of a difference with source references. The tool does not invent missing contract terms, decide a legal dispute, or send a supplier claim automatically.
What people approve
Energy managers confirm document versions, meter factors, dates, applicable rates, and billing terms. They approve findings and decide whether to raise a question with the provider. Credits, disputes, and payment decisions stay with authorized people.
What we’d need to start
- Bills and agreed rate schedules with source versions and billing dates
- Meter readings, multipliers, site identifiers, and relevant adjustment records
- The charges to check, rounding rules, exclusions, and named billing reviewers
How we’d test it
Use known examples with rate changes, overlapping periods, meter factors, rounding, credits, and missing terms. Compare with independently checked calculations and ensure all source links resolve. Do not label a disputed difference as an approved credit or recovered saving.
Prepared for Energy & sustainability. We would agree on the work after reviewing your brief, materials, and requirements.
