MOL for municipalities, property funds and multi-site corporates.
A municipality protecting its revenue, a property fund recovering costs from tenants and a retailer tracking its energy spend across sites all need to know what was consumed, and to be able to prove it. PMT meets each of these needs with MOL. What differs by sector is which parts of MOL do the work.
Municipalities & utilities
Revenue that can be defended at audit.
A metro's electricity revenue is concentrated in a comparatively small number of large customers. Those customers have the technical capacity to query a bill and the commercial reason to do so.
Defending that revenue depends on the metering. A metering fault only becomes visible at billing, and by then the dispute is about the credibility of the bill.
Large power user metering
Metering for the customers who account for most of the revenue, read every thirty minutes. The billing determinants hold up when the customer's own consultant queries them.
Outage detection
PMT's outage gateways send a last-gasp notification. The topology model directs the crew to the highest connection point where the trip occurred, and matches the dispatch to the switching authority required.
Revenue protection
Phasor diagnostics detect reversed CTs (current transformers) and swapped phases, faults that leave a meter reading plausibly but billing wrongly. Tamper events are logged and reported.
Prepayment for commercial and industrial tariffs
Prepayment for commercial and industrial customers on tariffs that an STS (Standard Transfer Specification) token meter cannot apply: time of use, maximum demand, network charges, and multiple utilities on one balance.
Property funds & centre management
Tenant recoveries that reconcile, and bills tenants can check.
A landlord reselling electricity is required to charge tenants as though they were buying directly from the municipality. The obligation is straightforward but difficult to evidence, and most tenants have no practical way to confirm the charge passed to them is the charge the tariff permits.
Metering that can be shown to a tenant line by line settles the question before it becomes a dispute. It also tends to show losses the centre has been absorbing.
Tenant recovery that reconciles
Sub-metering of every tenant, plant room and common area, apportioned by rules you set and billed on the municipal tariff you are legally required to pass through.
Standby generation cost recovery
Diesel generation costs several times as much as grid supply. Conditional virtual meters bill generator-supplied consumption at a different rate from utility-supplied consumption. This is done in software, without duplicating the reticulation or adding a control system.
Solar apportioned to tenants
Tenants account for most of a centre's consumption, so most of a rooftop array's output is consumed by tenants. Virtual metering distributes the benefit to tenants pro rata rather than leaving it with the landlord.
Bill verification
Independent check meters, and a recalculation of every charge on the bill you receive (the tariff as well as the reading).
Multi-site corporates
Energy budgets built on interval data.
Most energy budgets assume next year will look much like last year, then add a factor for tariff increases and any major change in occupancy. The results are predictably inaccurate, and by the time the variance shows in the accounts the financial year is over.
Interval data shows consumption by site, by day and by half hour, measured against a baseline that already accounts for the weather.
Every site reported on one basis
Interval data from every branch, store or plant, whatever meters are installed and whoever the landlord is, reported through one hierarchy.
Weather-normalised baselines
Baselines are weather-normalised by regression against heating and cooling degree days, so a variance indicates a change in consumption rather than a warm month.
Benchmarking against business activity
Energy per square metre tells a retailer very little. Energy per unit of sales, per cover, per available room or per tonne of production gives an operations manager a figure to act on.
Baseload measurement
Baseload is what a site draws when nobody is there. It is usually the cheapest saving available and is rarely measured.
The same applies to water, gas, compressed air and heat. A traditional water meter gives a running total, so the manager cannot see how much was used on any given day or whether water is being consumed after hours. Recorded as interval data, it shows daily use, after-hours use and leaks.
Operated by your own team or by PMT.
Some customers operate MOL with their own team. Others contract PMT for the whole function: installation and commissioning, meter reading, data management, bill verification, tariff analysis and the monthly billing pack.
Most sit somewhere between the two and move along that range over time. MOL is the same in either case, so changing the arrangement later is a staffing decision rather than a migration project.
